You decide to determine, once and for all, which chocolate brownies are best-- yours or your sister-in-law's Yolanda-- by devisi

ng a test of hypothesis. She is a superb baker and she mocks your baking as inferior. Undaunted, you decide to randomly select 100 names from the NYC phone book. You contact each selected individual and they agree to participate in your study. Then, you send your brownies with instructions for rating the taste and one week later you send Yolanda's brownies with the same instructions. Each group rates the brownies on a 10 point ordinal scale--10 implies exquisite and 1 implies inedible. True or False: This test is performed on paired or matched samples.

Write an equation in point-slope form and slope-intercept form for each line.
Crank
Point slope formula is y-y1=m(x-x1)
The slope is -3. So you just plug in what you know which is the (x1,y1). So the point slope form is y+1=-3(x-4).
The slope intercept form is y=mx+b. So you plug in the m,x, and y to solve for b. B is 11. So the slope intercept form is y=-3x+11.

Which choice shows +=7
V125BC [204]

Answer:

y=-x +7 is the slope-intercept form and the graph is shown in the attachment.

Step-by-step explanation:

The given equation is

x + y = 7

We solve for y to get:

y =  - x + 7

This is now of the form, y=mx+c

This is called the slope-intercept form.

Since the slope is negative, the graph slopes backwards. Also the y-intercept is 7, so the graph will intersect the y-axis at 7

If they want a sample committee consisting of four male and four female students, from a possible volunteer pool of eight male a
andreyandreev [35.5K]

Answer:

There are 2450 ways.

Step-by-step explanation:

We can pick first the 4 man, and then the 4 women. The configuration of men and women are independant with each other, so the total of possibilities is obtained by multiplying the total possibilities to pick 4 men and the total possibilities of picking 4 women.

To pick 4 men from a group of 8, the total number of possibilities is the amount of ways to pick 4 elements from a group of 8. This number is represented by the combinatorial number of 8 with 4

{8 \choose 4} = \frac{8!}{4!4!} = 70

To pick 4 women from a group of 7, we need to count the total amount of ways to pick 4 elements from a group of 7. This is the combinatorial number of 8 with 7

{7 \choose 4} = \frac{7!}{4!3!} = 35

Hence, the total amount of ways to pick 4 men and 4 women from a group of 8 men and 7 women is 70*35 = 2450.

Please solve this with explanation, don’t just give the answer please explain too.
Gemiola [76]

Answer: 30x⁴

Step-by-step explanation:

2x⁴ + (-3x²)² + 10(x²)² + (-3x²)²

2x⁴ + (9x⁴) + 10 (x⁴) + (9x⁴)

2x⁴ + 9x⁴ + 10x⁴ + 9x⁴

2x⁴ + 10x⁴ 9x⁴ + 9x⁴

12x⁴ + 18x⁴

30x⁴

(-x)² = x²

(xᵃ)ᵇ = xᵃᵇ
