The probability that the sample mean is within 1 month of the population mean is 0.7794, which is equivalent to a 77.94% chance.

The standard deviation of the lifespan of a certain brand of LED light bulbs is 13 months. The mean lifespan of all light bulbs produced by the company is 156 months. We want to find the probability that the sample mean is within 1 month of the population mean. To solve this problem, we need to use the z-score. The z-score is calculated as (sample mean - population mean) / standard deviation. In this case, the z-score is (156 - 155) / 13 = 0.077. We can then use a z-score table to find the probability. Using the table, we find that the probability is 0.7794. This means that there is a 77.94% chance that the sample mean is within 1 month of the population mean.

The interpretations of the functions for the new garden plots are as follows:

A(x) = x^2 represents the area of the original garden plot. Now, let's take a look at the other three functions:

Garden B: A(x) = x^2 + 8x + 7

This function adds 8x and 7 to the original garden plot area. This means that the garden will be wider and longer than the original plot. The 8x term indicates that the garden will be extended by 8 feet in length, and the constant term 7 indicates that the garden will be extended by 7 feet in width. Therefore, Garden B will be bigger than the original garden.

Garden C: A(x) = x^2 - 9

This function subtracts 9 from the original garden plot area. This means that the garden will be shorter and narrower than the original plot. The -9 term indicates that the garden will be reduced by 9 feet in width. Therefore, Garden C will be smaller than the original garden.

Garden D: A(x) = x^2 - 13x + 36

This function subtracts 13x and adds 36 to the original garden plot area. This means that the garden will be shorter and wider than the original plot. The -13x term indicates that the garden will be reduced by 13 feet in length, and the constant term 36 indicates that the garden will be extended by 36 feet in width.

To generate Pythagorean triples using an odd number, follow these steps:

Choose any odd number, say n.

Calculate (n^2-1)/2 and n. These two numbers will form a Pythagorean triple.

Check if the numbers obtained in step 2 are indeed a Pythagorean triple. The two numbers should satisfy the Pythagorean theorem, i.e., a^2 + b^2 = c^2, where a and b are the smaller numbers, and c is the largest number.

If the numbers in step 2 do not form a Pythagorean triple, choose a different odd number and repeat the process.

For example, let's choose the odd number 5:

(n^2-1)/2 = (5^2-1)/2 = 12

n = 5

Now, we can check if 5, 12, and 13 form a Pythagorean triple:

Using the concept of similar triangles, we were able to find the height of the tree given the man's height, distance from the tree, and distance from the steak. The tree is approximately 6.25 feet tall.

We can use similar triangles to find the height of the tree. Let x be the height of the tree in feet. Then, we have:

x / (x+5) = 6 / 30

Cross-multiplying, we get:

30x = 6(x+5)

Expanding and simplifying, we get:

30x = 6x + 30

24x = 30

x = 1.25

Therefore, the tree is 1.25 + 5 = 6.25 feet tall.

When a same bottle of ethanol starts at 10°C and absorbs 2500 J of heat, its final temperature is 45°C.

This problem can be solved using the specific heat capacity formula, which is expressed as

Q= mc ∆T

where Q is the amount of heat absorbed, m is the mass, c is the specific heat capacity and ∆T is the change in temperature.

The initial temperature of ethanol = 10°C

The amount of heat absorbed = 2500 J

We need to find the final temperature of ethanol. Let's use the specific heat formula to solve for the final temperature.

Q=mc∆T

where, Q = amount of heat absorbed = 2500 J

c = specific heat of ethanol = 2.44 J/g°C

∆T = change in temperature = final

temperature - initial temperature m = mass of ethanol

We need to calculate the mass of ethanol to use this formula.

Let's assume that the mass of ethanol is

100 g.m = 100 gQ = mc∆T2500 = 100 × 2.44 × ∆T ∆T = 10.25°C

Now, let's add this change in temperature to the initial temperature to find the final temperature.

Final temperature = Initial temperature + ∆T Final temperature = 10°C + 10.25°C

Final temperature = 20.25°C + 24.75°C

The variation model can be used to find the value of f = 42(m/p) for any given values of m and p.

What is the variation model?

The variation model is a mathematical model that describes the relationship between two or more variables. It is used to represent how the value of one variable changes in response to changes in another variable. The variation model can be direct or inverse, depending on whether the two variables change in the same direction or in opposite directions. In a direct variation model, two variables are directly proportional to each other, meaning that when one variable increases, the other variable also increases in the same proportion. This can be represented mathematically as y = kx. In an inverse variation model, two variables are inversely proportional to each other, meaning that when one variable increases, the other variable decreases in the same proportion. This can be represented mathematically as y = k/x.

If f varies directly with m and inversely with p, we can write:

f ∝ m/p

Using the constant of proportionality k, we can write:

f = k(m/p)

To find the value of k, we can use the given information that f=36 when m=6 and p=7:

36 = k(6/7)

Solving for k, we get:

k = 36(7/6) = 42

Now that we have the value of k, we can use the variation model to find the value of f for any given values of m and p:

f = 42(m/p)

Bill needs to make monthly payments of approximately $206.81 in order to pay off his balance in 18 months.

The effective rate of interest the bank is charging Bill is approximately 10.4%

From the question, we are to calculate how much Bill's monthly payment will be

To find the monthly payment Bill needs to make in order to pay off his balance in 18 months, we can use the formula for the present value of an annuity:

PMT = PV / ((1 - (1 + r)^(-n)) / r)

Where PMT is the monthly payment

PV is the present value of the outstanding balance

r is the monthly interest rate

and n is the number of payments (in this case, 18).

First, we need to calculate the monthly interest rate. Since the annual interest rate is 9.7%, the monthly interest rate is:

r = 0.097 / 12 = 0.0080833

Next, we can plug in the values for PV, r, and n:

PMT = 3400 / ((1 - (1 + 0.0080833)^(-18)) / 0.0080833)

PMT ≈ $206.81

Hence, Bill needs to make monthly payments of $206.81

To find the effective rate of interest the bank is charging Bill, we can use the formula:

(1 + r)^12 - 1

Where r is the monthly interest rate.

Plugging in the value for r, we get:

(1 + 0.0080833)^12 - 1 ≈ 0.104

so you would have to see what 35 can be multiplied to get to 150.

obviously no number multiplied by 35 will get you 150, but if you multiply 35 x 4, you will get 140, which is close enough, yet still you don't have enough for a full 4 hours.

Then you have to consider that you still need to pay $20 just to rent the ski boat alone.

So that will take away from the money you have.

when you subtract 20 from 140, you will still not have enough money for 4 whole hours, therefore you will only have enough for 3 hours with the $ 120 you have left.

The probability that both her selections are vegetarian is 1/14.

What is probability?

Probability is a branch of mathematics that deals with the study of random events or processes. It is the measure of the likelihood or chance of an event or outcome occurring, expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

There are 15 toppings in total, so there are 15 ways for the customer to choose her first topping.

If the first topping is vegetarian, there are 8 vegetarian toppings left out of 14 total toppings, so there are 8 ways for the customer to choose a second vegetarian topping.

If the first topping is non-vegetarian, there are 7 vegetarian toppings left out of 14 total toppings, so there are 7 ways for the customer to choose a second vegetarian topping.

Therefore, the total number of ways for the customer to choose two vegetarian toppings is 8 + 7 = 15.

The total number of ways for the customer to choose two toppings is the number of ways to choose the first topping (15) multiplied by the number of ways to choose the second topping after the first topping has been chosen (14).

Therefore, the total number of ways for the customer to choose two toppings is 15 x 14 = 210.

The probability of choosing two vegetarian toppings is the number of ways to choose two vegetarian toppings (15) divided by the total number of ways to choose two toppings (210):

P(choosing two vegetarian toppings) = 15/210

Simplifying the fraction by dividing the numerator and denominator by 15, we get:

P(choosing two vegetarian toppings) = 1/14

Therefore, the probability that both her selections are vegetarian is 1/14.

We can now use the fact that the total number of customers who shopped during the sale is equal to the sum of the customers who bought either pints or gallons of paint and those who did not buy any paint:

224 + y + 48 = x + y + 107 + 92

Simplifying the equation, we get:

y + 272 = x + 199

x - y = 73

Finally, we can add up all the customers who shopped during the sale:

107 + 132 + 15 + 48 = 302
