Answer:

a) 3 b) 5 c) 7 d) 9

Step-by-step explanation:

For this, you want to replace x in the equation y=x+5 with each of the values listed.

For the first one, -2, the equation becomes y=-2+5, which is solved to y=3.

For the second one, 0, the equation becomes y=0+5, which is solved to y=5.

For the third one, 2, the equation becomes y=2+5, which is solved to y=7.

For the last one, 4, the equation becomes y=4+5, which is solved to y=9.

PLEASE HELP WITH THESE 4 PROBLEMS

Marizza181 [45]

Answer:

y = -5/2x + 5
y = 2x -1
y = 24/11
y = 4x + 4

Step-by-step explanation:

To solve for y, subtract the x-term and divide by the coefficient of y.

5x +2y = 10

2y = -5x +10

y = -5/2x + 5

2y -4x = -2

2y = 4x -2

y = 2x -1

7y +4y = 24

y = 24/11

We assume there is a typo, but cannot tell what it is. Use the same method as described and demonstrated for the other problems.

-2x +1/2y = 2

1/2y = 2x +2

y = 4x +4

salantis [7]

Answer:

Cohen's D

Step-by-step explanation:

Cohen's D is a statistic that measures effect size. It shows standardised difference between 2 means.

Effect size is defined as how large the effect of a something is or its magnitude.

Cohen's D works effectively when the sample is >50 (that is for large samples). However a correction factor can be used to make results from small samples more accurate

The formular for Cohen's D is:

D = (mean1 - mean2) ÷ (√({standard deviation1}^2 + {standard deviation 2}^2)/2)

This is the most appropriate method in the given scenario

Hey 20 points for the first person to show work and answer this

Harrizon [31]

Step-by-step explanation:

First, the pizza is 18 inches in diameter, so

$d = 18$

and, because the radium is half of the diameter,

$r = 9$

<u>Note that the units are inches.</u>

Using the equation

$a = \pi r ^{2}$

where a is the area of a circle, we know that the area of the whole pizza is approx.254.5 square inches. Divide by 8 to find the area of 1/8 of a pizza. Each slice will have an area of approx. 32 square inches. For a precise result, the answer is

$a(s)= \frac{(\pi \times 9^{2})}{s}$

where a(s) is the area of a slice of pizza, and s is the total number of slices, given they are equal in size.
