The sum of two positive integers, x and y, is not more than 40. The difference of the two integers is at least 20. Chaneece choo

ses x as the larger number and uses the inequalities y ≤ 40 – x and y ≤ x – 20 to determine the possible solutions. She determines that x must be between 0 and 10 and y must be between 20 and 40. Determine if Chaneece found the correct solution. If not, state the correct solution.

Value of expression 6 3/4(-11.5)
Inessa [12570]

Answer:

6 * 3/4 = 4.5 = 9/2 = 412

Step-by-step

6 * 3/4 = 6/1  3*4 = 18/4 = 9/2

2 · 2 = 9/2

Both the numerators and denominators are to be multiplied. Retain the resulting fraction with the lowest possible denominator; GCD(18, 4) = 2. In this intermediate calculation, cancelling by the common factor of 2 results in 9

2

.

In summary - six times three quarters equals nine halves.

Sal recorded the number of crackers in each snack-sized package he opened. Which statement must be true according to the box plo
PIT_PIT [12445]

Response:

The data shows skewness, with the minimum amount of crackers in a pack being 7

Detailed explanation:

Hello,

Firstly, the question lacks completeness due to missing information from the box plot, which I have provided to assist you in answering your inquiry.

Considering the details from the attached image, a symmetric distribution would be centered evenly, but that is not the case here.

The image indicates a positive skew, with the lowest count recorded as 7.

A set of speakers costs $22 and songs cost $1.25 each. The sales tax rate is 7.5%. The expression 0.075(22 + 1.25s) can be used
Leona [12618]

Answer:

1.65 + 0.09s

Step-by-step explanation:

Considering that:

Cost of speaker = $22

Cost per song = $1.25

Sales tax rate = 7.5%

To find the sales tax on the total purchase, use the expression: 0.075(22 + 1.25s)

Expanding this expression:

0.075(22 + 1.25s)

(0.075 * 22) + (0.075 * 1.25s)

1.65 + 0.09375s

Rounding to two decimal places:

The total sales tax on the purchase is:

1.65 + 0.09s
