Answer:

D. 10x - 20

Step-by-step explanation:

The perimeter is the sum of all the sides of the rectangle.

Set up your equation. Because the opposite sides of the rectangle are equal, you add them twice or multiply it by 2.

P = 2(2x - 8) + 2(3x - 2)

Now distribute the 2 across the parentheses.

P = 4x - 16 + 6x - 4

Combine the variables.

P = 10x - 16 - 4

Combine the constants.

P = 10x - 20

Use the formula to find the standard error of the distribution of differences in sample means, x¯1-x¯2 . Samples of size 110 fro
Volgvan

Answer:

2.104

Step-by-step explanation:

Data provided in the question:

For sample 1,

n₁ = 110

μ₁ = 94

s₁ = 14

For sample 2,

n₂ = 85

μ₂ = 72

s₂ = 15

Now,

Standard error = \sqrt{\frac{s^2_1}{n_1}+\frac{s^2_2}{n_2}}

or

Standard error = \sqrt{\frac{14^2}{110}+\frac{15^2}{85}}

or

Standard error = √4.43

or

Standard error = 2.104

lora16 [44]

Answer:

3/16

Step-by-step explanation:

Let the size of the whole apple be T

Given that 3/4 of the apple is left, it means the size left

= 3T/4

Since Victor plans to eat 1/4 of the pie that was left, this amounts to

1/4 * 3T/4

= 3T/16

This means that Victor will eat 3/16 of the whole pie tomorrow
