Three vertices of a rectangle are shown on the grid. I NEED HELP PLEASE

Answers

Answer:

(6,7)

Step-by-step explanation:

The great thing about rectangles is that they are super simple. For the top right point, it is going to share an x-value with the bottom right vertex and and y-value with the top left. This maintains the parallel lines that define a rectangle. So just find the x coordinate of the bottom right vertex (6) and the y coordinate of the top left (7) and put them together: (6,7)

Aline read a report saying 39% of teachers in the United State were members of a labor union. She wants to test whether this holds true for teachers in her state, so she is going to take a random sample of teachers and see what percent of them are members of a union. Let p represent the proportion of teachers in her state that are members of a union. Write an appropriate set of hypotheses for her significance test.

Answers

Answer:

H0: p= 0.39 vs Ha: p ≠ 0.39

Step-by-step explanation:

She wants to test whether this holds true for teachers in her state.

The test is the formulated into the hypotheses.

The null hypothesis would be

H0: p= 0.39 against the claim Ha: p ≠ 0.39

The null hypothesis tells that the the proportion of teachers in her state that are members of a union is equal to the proportion of teachers in the US that are members of the labor union.

against the claim

That the the proportion of teachers in her state that are members of a union is not equal to the proportion of teachers in the US that are members of the labor union.

m<D = 26

Step-by-step explanation:

Exterior angles thm:

83 + 6x - 4 = 21x + 4

6x + 79 = 21x + 4

6x - 21x = 4 - 79

-15x = -75

x = 5

if f(x) =2x-1 and g(x) =3x+2 find the fof(x)

Answers

Answer: 4x - 3

=================================================

Explanation:

We won't involve the g(x) function at all.

We're composing the f(x) function with itself, which means we're replacing every x with f(x) and then simplifying.

HELP WITH GEOMETRY SURFACE AREA, PAT ATTENTION TO THE DOUBLE SIDED RADIUS!!

Answers

Answer:

Half of 3 is 1.5(new radius)

1.5^2 = 2.25

2.25 x 3.14 = 7.065

7.065 x 2 = 14.13(area of two circles)

2 x 3.14 x 1.5 = 9.42

9.42(circumference) x 4(height) = 37.68(area of lateral)

Add the given areas:

37.68 + 14.13 = 51.81 cm2 is your answer.

there are 677,040 possible ways to arrange the boxes.

b) unlike question a, this is a permutation. the order matters.
