Chrissie thinks of a number. 30% of her number is 270. What is the number she is thinking of?

Answers

The number Chrissie is thinking of is 900. This is obtained by solving the equation 0.3x = 270.

Let's call the number Chrissie is thinking of "x". We know that 30% of x is equal to 270.

We can write this as an equation:

0.3x = 270

To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides by 0.3:

x = 270 ÷ 0.3

x = 900

So the number Chrissie is thinking of is 900.

An equation is used to find the number Chrissie is thinking of. 30% of the number is equal to 270, so we can solve for the number by dividing 270 by 0.3, which gives us x = 900. Therefore, the number Chrissie is thinking of is 900.

The average number of vehicles waiting in a line to enter a parking ramp can be modeled by the function f(x)= 5(2−x)x 2where x is a quantity between 0 and 1 known as the traffic intensity. Find the rate of change of the number of vehicles in line with respect to the traffic intensity for x=02. The rate of change for x=0.2 is (Simplity your answer. Type an integer of decimal rounded to four decimal places as neoded)

Answers

The rate of change of the number of vehicles in line with respect to the traffic intensity for x=0.2 is -1.2000. The formula used to calculate the rate of change is the derivative of the given function f(x).

To find the rate of change of the number of vehicles in line with respect to the traffic intensity at x = 0.2, we need to take the derivative of the function f(x) with respect to x and then evaluate it at x = 0.2.

f(x) = 5(2 - x)x^2

f'(x) = 5[(2 - x)(2x) + x^2(-1)]

f'(x) = 5(4x - 3x^2)

f'(0.2) = 5(4(0.2) - 3(0.2)^2) = 0.68

Therefore, the rate of change of the number of vehicles in line with respect to the traffic intensity for x = 0.2 is 0.68.

Steve goes from Birmingham to Coventry by bus. He takes 9 minutes to walk from his house to the bus stop in Birmingham. He takes 12 minutes to walk from the bus stop in Coventry to work. Steve has to get to work by 10 am. What is the latest time Steve should leave his house to get to work on time?

Answers

Steve should leave his house no later than 8:49 am (10:00 am minus 529 minutes) to get to work on time.

Minutes or minutes is correct?

It's preferable to spell out the term minutes entirely rather than shorten it. Sixty seconds make up one minute, which is a measure of time. Minutes are a noun that also refers to the records of a formal meeting. The abbreviation "min" is frequently used.

Let's call the hour Steve needs to leave his house to leave for work "x".

He needs 9 minutes to walk from his home to the bus stop, and we don't know how long it will take the bus to get from Birmingham to Coventry. Call the length of the bus ride "t" for now.

Steve needs 12 minutes to walk to work from the bus stop in Coventry.

So, Steve's commute to work takes a total of:

Walking from the bus stop in Coventry to work takes 12 minutes, and it takes 9 minutes to go to the bus stop in Birmingham, thus the total time is 21 + t minutes.

Steve needs to arrive at work by 10 a.m., or 10 x 60 = 600 minutes.

Thus, we can formulate the equation shown below:

x + 21 + t <= 600

After finding x, we obtain:

x <= 579 - t

This indicates that Steve must leave his home no later than 579 minutes before 10 am, rounded to the nearest minute, minus the time it will take him to take the bus there and back (t).

For instance, if the bus ride takes 50 minutes, Steve should leave his house no later than:

x <= 579 - 50 = 529

In order to arrive at work on time, Steve must leave his residence no later than 8:49 am (10:00 am minus 529 minutes).

After answering the given query, we can state that As a result, function  g(x) = 7x + 2 indicates the translation that occurs 1 unit to the left of f(x) = 7x - 5.

what is function?

Mathematicians research numbers, their variations, equations, associated structures, shapes, and possible configurations of these. The relationship between a group of inputs, each of which has a corresponding outcome, is referred to as a "function." A function is a relationship between inputs and outputs where each input results in a unique, distinct output. Each function has a domain, codomain, or scope assigned to it. Functions are commonly denoted by the letter f. (x). An cross is entered. On functions, one-to-one capabilities, so several capabilities, in capabilities, and on functions are the four main categories of available functions.

The function f(x) = 7x - 5 must be translated 1 unit horizontally to the left in order to determine g(x).

In order to solve for f, we must substitute x in the equation with (x + 1) when there is a horizontal translation of 1 unit to the left.(x). This is due to the fact that by replacing x with x + 1, we are actually moving the curve of f(x) to the left by one unit.

So, g(x) = f(x + 1) can be expressed as:

g(x) = 7(x + 1) - 5

g(x) = 7x + 2

As a result, g(x) = 7x + 2 indicates the translation that occurs 1 unit to the left of f(x) = 7x - 5.

What are the multiples of 12, of which the square root is 6

Answers

The only multiple of 12 with a square root of 6 is 12 times 3, or 36 using generate multiples of 12 .

The multiples of 12 are numbers that are divisible by 12 without a remainder. We can generate multiples of 12 by multiplying 12 by any integer. For example, the first few multiples of 12 are 12, 24, 36, 48, 60, and so on.

To find which multiples of 12 have a square root of 6, we can use the following formula:

√(12n) = √(12) * √(n)

Since the square root of 12 is equal to 2 times the square root of 3, we can simplify the formula as follows:

√(12n) = 2 * √(3n)

If the square root of 12n is equal to 6, then we can set up an equation and solve for n:

2 * √(3n) = 6

√(3n) = 3

3n = 9

n = 3

In summary, we can use the formula √(12n) = 2 * √(3n) to find which multiples of 12 have a square root of 6. By solving for n, we find that the only multiple of 12 with a square root of 6 is 36.

Answer: 3

Step-by-step explanation:

On Saturday night, lots of people attend movies at the State Theater. The number who attends depends at least in part on the price of the tickets. At the current price of $8 per ticket, an average of 285 tickets are sold each Saturday night. What is the trice and the quantity demanded in this example?

Answers

From the given information provided,  the quantity demanded at a price of $8 per ticket is 293 tickets.

The demand in this example refers to the relationship between the price of movie tickets and the quantity of tickets that people are willing and able to buy at that price.

From the given information, we know that the current price of a movie ticket is $8 and the quantity demanded at that price is 285 tickets. However, we would need additional data points at different prices to get a more accurate estimate of the demand function.

Assuming that the demand for movie tickets is downward sloping (i.e., as the price of tickets increases, the quantity demanded decreases), we can say that the demand is:

Inverse: The price and quantity demanded move in opposite directions. When the price of tickets goes up, the quantity demanded goes down, and vice versa.

Negative: The slope of the demand curve is negative, indicating that there is an inverse relationship between the price and quantity demanded.

To estimate the quantity demanded at different prices, we can use the formula for a linear demand function:

Q = a - bP

where Q is the quantity demanded, P is the price, a is the intercept (the quantity demanded when the price is zero), and b is the slope (the change in quantity demanded for a one-unit change in price).

Using the given data point of $8 and 285 tickets, we can estimate the intercept:

285 = a - 8b

Assuming a relatively elastic demand, we can use a slope of -2:

Q = a - 2P

Substituting the intercept value we solved for earlier, we get:

Q = 309 - 2P

This is the estimated demand function for movie tickets based on the given information.

To answer the question of what is the quantity demanded, we can use the given data point of $8 per ticket and plug it into the demand function:

Q = 309 - 2(8)

Q = 293

Mr. Razon paid Php87 his lunch What % of his Php 100 did he paid for his lunch

Answers

Mr. Razon paid 87 percent of his Php 100 for his lunch.

What is percentage increase and decrease?

We first calculate the difference between the original value and the new value when comparing a rise in a quantity over time. The relative increase in comparison to the initial value is then determined using this difference, and it is expressed as a percentage. The relative reduction in comparison to the starting value is then determined using this difference, and it is expressed as a percentage.

The response denotes a percentage increase if the percent change number is positive. If the value is negative, it can be expressed as a positive number and designated as a reduction in percentage.

To find the percentage that Mr. Razon paid for his lunch, we can use the formula:

percentage = (part / whole) x 100%

Answers

D)probability that the sample proportion is between 0.56 and 0.59 is 0.7912.

E)Probability that the sample proportion is less than 0.51 is 0.0002

D. To calculate the probability that the sample proportion is between 0.56 and 0.59, we can use the Standard Normal Probability Distribution Table. To do this, we first calculate the standard score, or z-score, for the lower bound and the upper bound of our desired range. The formula for calculating the z-score is:


z = (x - μ) / σ


where x is the value for which you want to find the z-score, μ is the population mean, and σ is the population standard deviation. In this case, x is the sample proportion, μ is 0.61, and σ is 0.01. Therefore, the z-score for the lower bound (0.56) is -2.90, and the z-score for the upper bound (0.59) is -0.33. We can then look up the corresponding probabilities in the Standard Normal Probability Distribution Table. The probability that the sample proportion is between 0.56 and 0.59 is 0.7912.

E. To calculate the probability that the sample proportion is less than 0.51, we can use the same process as above. The z-score for 0.51 is -3.90. We can look up the corresponding probability in the Standard Normal Probability Distribution Table, which is 0.0002. Therefore, the probability that the sample proportion is less than 0.51 is 0.0002.

That is, the probability that none of the four patients will worsen to severe sepsis or septic shock after three days is 0.6561, so the probability that at least one patient will worsen to severe sepsis or septic shock after three days is:

[tex]1 - 0.6561 = 0.3439[/tex]

Therefore, there is a 34.39% chance that at least one patient will worsen to severe sepsis or septic shock after three days.

At school there is a group planning the exhibition.
There are 20 people in the group and the mean of their ages is 12 years. Three new people whose ages are 10, 11 and 15 join the group.
How does this affect the mean?

Answers

Answer:

The mean of a group is calculated by adding up all the values in the group and then dividing by the number of values. In this case, the mean age of the original group of 20 people is 12 years. This means that the sum of their ages is 20 * 12 = 240 years.

When three new people with ages 10, 11, and 15 join the group, the total number of people in the group increases to 23. The sum of their ages becomes 240 + 10 + 11 + 15 = 276 years. The new mean age of the group is calculated by dividing the sum of their ages by the number of people in the group: 276 / 23 ≈ 12 years.

So, after three new people join the group, the mean age remains approximately the same at around 12 years.

what is the average rate of change of f(x) from x=-4 to x=0?

Answers

The average rate οf change οf f(x) is equal tο the slοpe οf the line passing thrοugh the twο pοints, which is (y₂ - y₁) / 4.

What is the average rate οf change?

The average rate οf change is a mathematical cοncept that describes the rate at which a quantity changes οver a certain periοd οf time οr οver a certain range οf values. In calculus, the average rate οf change is οften used tο estimate the instantaneοus rate οf change οf a functiοn at a specific pοint.

Tο find the average rate οf change οf a functiοn οver an interval [a, b], we calculate the slοpe οf the line cοnnecting the twο pοints (a, f(a)) and (b, f(b)). This is given by the fοrmula:

average rate οf change = (f(b) - f(a)) / (b - a)

Tο calculate the average rate οf change οf f(x) frοm x=-4 tο x=0, we need tο find the slοpe οf the line cοnnecting the twο pοints.

The fοrmula fοr the slοpe οf a line passing thrοugh twο pοints (x₁, y₁) and (x₂, y₂) is:

slοpe = (y₂ - y₁) / (x₂ - x₁)

In this case, the twο pοints are (-4, f(-4)) and (0, f(0)). We dοn't have the specific values οf f(-4) and f(0), sο we'll use variables tο represent them. Let's say f(-4) = y₁ and f(0) = y₂.

Then the slοpe οf the line is:

slοpe = (y₂ - y₁) / (0 - (-4)) = (y₂ - y₁) / 4

Sο the average rate οf change οf f(x) frοm x=-4 tο x=0 is equal tο the slοpe οf the line passing thrοugh the twο pοints, which is (y₂ - y₁) / 4.

Decreasing Size of Cattle Herd. Drought has been the major reason for the decrease in the U. S. Cattle herd in recent years. The number of cattle is at its lowest level since 1952. In 2006, there were 96. 6 million head of cattle. This number had fallen to 87. 7 million by 2014. (Source: U. S. Department of Agriculture) Find the average rate of change in the number of cattle from 2006 to 2014

Answers

the average rate of change in the number of cattle from 2006 to 2014 is approximately -1.1125 million head of cattle per year.

To find the average rate of change in the number of cattle from 2006 to 2014, we need to divide the total change in the number of cattle over that period by the number of years.

The total change in the number of cattle is:

87.7 million - 96.6 million = -8.9 million

The number of years is:

2014 - 2006 = 8

So, the average rate of change is:

-8.9 million / 8 years = -1.1125 million per year

Mr. Crawford's class has 7 boys and 8 girls. Mrs. Ball's class has 4 boys and 10 girls. If one student is randomly selected from each class, what is the probability they are both boys?

A. 11/18
B. 2/15
C. 1/190
D. 1/24​

Answers

Given the chance of independent events, if one student is randomly selected from each class, the likelihood that both of them are female is 2/15.

What is the meaning of probability?

Probability relates the number of favourable events to the total number of possible events.

Thus, to determine the chance of any event, the ratio between the number of favourable cases (cases in which event A may or may not occur) and the total number of potential cases is employed. A:

Number of likely cases x Number of potential cases equals probability.

The number of independently likely events.

Two occurrences A and B are said to be independent if and only if the likelihood of event B is unaffected by the occurrence of event A, or vice versa.

The sum of the probabilities for each individual event is the probability that every independent event, for any number of occurrences, will occur. In other words, if A and B are independent events, P(A and B) = P(A)P. (B).

The response indicates that Mr. Crawford's class has a total of 15 students (8 girls and 7 boys).

14 kids, 10 female and 4 males, are enrolled in Mrs. Ball's class.

The likelihood that a boy will be chosen in each class, if one student is randomly chosen from each, is computed as follows:

Probability in Mr. Crawford's class is 7/15 (7/15 x 15).

In Mrs. Ball's class, the probability is 4 14 = 4/14.

Given that these are separate occurrences, the likelihood that both students chosen for the classes are boys is determined as follows:

Chance that both of the students chosen for the classes will be boys: In Mr. Crawford's probability class In Ms. Ball's class, probability

Chance that both of the students chosen for the classes will be boys: 7/15 4/14

The likelihood that both of the students chosen for the classes are boys is 2/15.

Ultimately, there is a 2/15 chance that they are both boys.

A study of a population of 1500 rabbits revealed that 8 out every 75 rabbits in the population were females. Based on the results of this study, how many rabbits in the population are males?

Answers

As per the proportion, the number of males rabbits in the population is 1000.

Let's first find the proportion of female rabbits in the population using the given information. We are told that 8 out of every 75 rabbits in the population are females. Therefore, we can write:

Proportion of females = 8/75

We can simplify this fraction by dividing both the numerator and the denominator by the greatest common factor, which is 1:

Proportion of females = 8/75 = 0.1067

This means that for every unit of 75 rabbits in the population, there are 8 female rabbits.

Then, the total number of rabbits in the population is:

Total number of rabbits = r x 75

Since we know that the proportion of females is 0.1067, we can find the number of female rabbits in the population as follows:

Number of female rabbits = Proportion of females x Total number of rabbits

= 0.1067 x (r) x 75

We also know that the total number of rabbits in the population is 1500. Therefore, we can set up an equation as follows:

Number of male rabbits + Number of female rabbits = Total number of rabbits

Number of male rabbits + 0.1067 x (r) x 75 = 1500

Now, we can solve for the number of male rabbits by rearranging the equation:

Number of male rabbits = 1500 - 0.1067 x (r) x 75

We can simplify this expression by first multiplying 0.1067 and 75:

Number of male rabbits = 1500 - 8.003 x r

Finally, we can substitute the value of x in terms of the total number of rabbits in the population (1500) to find the number of male rabbits:

Number of male rabbits = 1500 - 8.003 x (1500/75)

Number of male rabbits = 1000

Therefore, there are 1000 male rabbits in the population.
