The soda machine contains 225 sodas at capacity. On average 15 drinks get dispensed per day.Write an equation in slope-intercept form to represent the total number of sodas in the vending machine in days.

Answers

Answer: y = -15x + 225

Step-by-step explanation:

slope-intercept form is y = mx + b

The 225 is the starting amount.

x is the number of days since the machine was loaded.

-15 is the amount subtracted on average per day. It is the slope, m

y is the number of sodas left in the machine

The area of a rectangle is 195 dm². The width is two less than the length. What is the length and the width of tge rectangle?

Answers

The length of the rectangle is 15 dm and the width is 13 dm.

Let's assume that the length of the rectangle is "L" and the width is "W".

From the problem statement, we have two pieces of information:

The area of the rectangle is 195 dm²:

Area = Length x Width

195 dm² = L x W

The width is two less than the length:

W = L - 2

Now, we can substitute the second equation into the first equation to eliminate W and get an equation with only one variable:

195 dm² = L x (L - 2)

Simplifying the equation:

195 dm² = L² - 2L

L² - 2L - 195 dm² = 0

To solve for L, we can use the quadratic formula:

L = (-b ± √(b² - 4ac)) / 2a

Where a = 1, b = -2, and c = -195.

L = (2 ± √(2² + 4 x 1 x 195)) / 2 x 1

L = (2 ± √4 + 780) / 2

L = (2 ± √784) / 2

L = (2 ± 28) / 2

L = 15 or L = -13

Since the length can't be negative, the length of the rectangle is L = 15 dm.

Now we can use the equation W = L - 2 to find the width:

W = 15 dm - 2 dm

W = 13 dm

Therefore, the length of the rectangle is 15 dm and the width is 13 dm.

#SPJ4

A researcher is using a repeated-measures study to evaluate the difference between two treatments. If the difference between the treatments is consistent from one participant to another, then the data should produce ______. A. a small variance for the difference scores and a small standard error
B. a small variance for the difference scores and a large standard error
C. a large variance for the difference scores and a small standard error
D. a large variance for the difference scores and a large standard error

Answers

Answer:

A) a small variance for the difference scores and a small standard error

Step-by-step explanation:

Since the difference scores are obtained by subtracting one variable form another, if the difference scores are consistent between treatments, then the variance will be small. The higher the variance, the higher the standard error. So if the variance is small, then the standard error will also be small.
