Answer:

Hammad has made his drink stronger in taste than Julie.

Step-by-step explanation:

We need to compare the ratio of juice to lemonade in each drink.

Julie's drink has a ratio of 42ml juice to 210ml lemonade, which simplifies to 1:5.

Hammad's drink has a ratio of 30ml juice to 170ml lemonade, which simplifies to 3:17.

To compare the strength of their drinks, we need to compare the ratios of juice to lemonade. Since a higher ratio of juice to lemonade indicates a stronger taste, we can see that Hammad's drink has a stronger taste, since his ratio of juice to lemonade is higher than Julie's.

Therefore, Hammad has made his drink stronger in taste than Julie.

The result is 5 1/3, not 5 1/4 as Lin suggested.

No, I don't agree with Lin's statement. Lin's explanation is incorrect.

When evaluating the expression 4 ÷ (3/4), we need to remember the order of operations, which states that we should perform the division before the multiplication.

To divide by a fraction, we can multiply by its reciprocal. The reciprocal of 3/4 is 4/3. Therefore:

4 ÷ (3/4) = 4 * (4/3)

Now we can simplify the expression:

4 * (4/3) = (4 * 4) / 3 = 16 / 3

The result, 16/3, is an improper fraction. To convert it to a mixed number (a whole number and a fraction), we divide the numerator (16) by the denominator (3):

16 ÷ 3 = 5 with a remainder of 1

The quotient is 5, and the remainder is 1. Therefore, the result is 5 1/3, not 5 1/4 as Lin suggested.

Answer:

To determine Laars' gross earnings per pay period under different payment frequencies, we need to divide his annual salary of $90,000 by the number of pay periods in a year for each frequency.

a. Monthly: Laars will receive 12 paychecks per year, one per month.

Gross earnings per pay period = $90,000 / 12 = $7,500 per month

b. Semi-monthly: Laars will receive 24 paychecks per year, two per month.

Gross earnings per pay period = $90,000 / 24 = $3,750 per semi-monthly period (twice per month)

c. Biweekly: Laars will receive 26 paychecks per year, one every two weeks.

Gross earnings per pay period = $90,000 / 26 = $3,461.54 per biweekly period (every two weeks)

d. Weekly: Laars will receive 52 paychecks per year, one per week.

Gross earnings per pay period = $90,000 / 52 = $1,730.77 per weekly period (every week)

Therefore, Laars' gross earnings per pay period are $7,500 per month, $3,750 per semi-monthly period, $3,461.54 per biweekly period, and $1,730.77 per weekly period.

The coefficient of variation for a Poisson distribution with A=5 is equal to 1/A, which is equal to 0.2.

Poisson Distribution is a type of probability distribution used for independent events which occur at a known average rate within a given interval of time or space. It is used to model the number of times an event is likely to occur within a specified period of time or space. It is used in fields such as healthcare, quality control, finance, and engineering.

Coefficient of variation (CV) is a measure of relative variability or dispersion. It is a measure of the relative dispersion of a set of data points around its mean. It is calculated by dividing the standard deviation of the data points by the mean.

The coefficient of variation for a Poisson distribution with A=5 is equal to 1/A, which is equal to 0.2. This means that the relative variability of a Poisson distribution with A=5 is 0.2. This is because the standard deviation of a Poisson distribution is equal to the square root of the mean, and in this case, the mean is 5. Therefore, the standard deviation is the square root of 5, or 2.236. When divided by the mean, the coefficient of variation is 0.2.

In general, the coefficient of variation is used to compare the variability of two different datasets. A low coefficient of variation indicates that the data points are relatively close to the mean and that there is not much variability in the data. A high coefficient of variation indicates that the data points are further away from the mean and that there is a greater amount of variability in the data.

Answer:

Step-by-step explanation:

thats all

The correct answer is interval 2. A function is a rule that relates each element in one set, called the domain, to exactly one element in another set, called the range.

It is a mathematical expression that takes an input, performs a calculation and produces an output.

In order to determine if dy/dx>0 and d2y/dx2<0 over interval 2, we must take the first and second derivatives of the function y=f(x). The first derivative of the function is dy/dx=2x-3 and the second derivative of the function is d2y/dx2=2.

Now, if we look at the graph, we can see that the function is increasing from 0 to 3 and then decreasing from 3 to 6. This means that over interval 2, which is from 3 to 6, the first derivative, dy/dx, must be negative. This means that dy/dx<0 over interval 2.

Furthermore, the second derivative, d2y/dx2, must be negative over interval 2 since the graph is decreasing over this interval. This means that d2y/dx2<0 over interval 2.

Therefore, the correct answer is interval 2 since it is the only interval for which both dy/dx>0 and d2y/dx2<0 are true.

Answer:

It is better to buy 6 pints at $8.10

Step-by-step explanation:

To compare the cost per pint in each option, we can divide the total cost by the total number of pints.

For the first option, buying 3 pints at $3.60, the cost per pint is shown by the following:

3 pints ÷ $3.60 = $0.83 / pint

For the second option, buying 6 pints at $8.10, the cost per pint is shown by the following:

6 pints ÷ $8.10 = $0.74 / pint

Therefore, buying 6 pints at $8.10 is less expensive per pint than buying 3 pints at $3.60. Each pint when buying 3 at a time costs $0.83 whereas each pint when buying 6 at a time costs $0.74.

The length of the side 'х' is 79.20 units to two decimal places.

Angle is a two-dimensional figure that is formed by two straight lines intersecting each other. It can also be defined as the amount of rotation between two lines or planes. An angle is measured in degrees, with a full rotation being 360°.

The given triangle is a right-angled triangle as it has an angle of 64° which is a right angle. The angle 35° and 113 are the other two angles of the triangle. To find the length of the side 'х', we need to use the Pythagorean Theorem. The Pythagorean Theorem states that "the square of the hypotenuse is equal to the sum of the squares of the other two sides".
In this case, the hypotenuse is 113, and the other two sides are 'х' and the perpendicular side opposite to the angle of 35°. Therefore, using the Pythagorean Theorem, we can say:
113² = х² + (perpendicular side)²
Using the trigonometric ratio sine, we can calculate the length of the perpendicular side opposite to the angle 35°, which is equal to the sine of 35° multiplied by the hypotenuse.
(perpendicular side) = sin 35° × 113
Therefore, the equation for the triangle now becomes:
113² = х² + (sin 35° × 113)²
Simplifying the equation and solving for 'х' gives us:
х² = 113² - (sin 35° × 113)²
х = √(113² - (sin 35° × 113)²)
Finally, substituting the values, we get:
х = √(113² - (sin 35° ×113)²)
 = √(12,841 - (0.5736 × 113)²)
 = √(12,841 - 6,539.7808)
 = √6,301.2192
 = 79.20
Therefore, the length of the side 'х' is 79.20 units to two decimal places.

Using percentage concept, we would have saved 2784.6 dollars after a year

To calculate how much you will have saved after a year, we can break down the savings for each week of each month, and then add up the total. Here's how it works:

We can use percentage to calculate how much is saved each week

In the first week of each month, you save 10% of your weekly allowance, which is 10 percent of 500 = 50 dollars.

In the second week of each month, you save 10% more than the previous week, which is 10% of (500 + 50) = 55 dollars.

In the third week of each month, you save 10% more than the previous week, which is 10% of (500 + 50 + 55) = 60.5 dollars.

In the fourth week of each month, you save 10% more than the previous week, which is 10% of (500 + 50 + 55 + 60.5) = 66.55 dollars.

So in total, you save 50 + 55 + 60.5 + 66.55 = 232.05  dollars per month.

Over the course of a year, you will have saved 232.05 dollars per month * 12 months = 2784.6 dollars.
