The product of 5 and a numberis -80

ad-work [718]

1. 5x= -80. x= -16

2. x - 73 = 129. x = 202

3. x/-8 = 22. x = -176

4. 2x + 8 = 8. 2x = 0. x = 0

5. 3x - 7 = 40. 3x = 47. x = 47/3

Find the coordinates of the midpoint M and the distance between J(4,3) and K(2,-3)

Sergio [31]

Answer:

(3,0)

Step-by-step explanation:

Co-ordinates of J =(4,3)

Co-ordinates of K = (2,-3)

Midpoint formula :

= $\frac{x_{1}+x_{2} }{2} , \frac{y_{1} +y_{2} }{2} \\ \frac{4+2}{2} ,\frac{3+(-3)}{2}\\\frac{6}{2},\frac{3-3}{2}\\3, 0$

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tail

Dahasolnce [82]

Answer: The parametric is being tested here is "p" (population proportion).

The hypothesis test is left-tailed.

Step-by-step explanation:

Given : The null and alternative hypotheses are

$H_0:\ p=0.2\\\\H_1:\ p$

The parametric is being tested here is "p", where p stands for population proportion.

Also, the type of test depends on the alternative hypotheses.

Since the alternative hypotheses is left-tailed, so the hypothesis test is left-tailed.

Please help me! I have no idea how to do this

elena-s [515]

The best way to do this is to make up values for the sides.

Say the lengths of square B's sides are each 4 cm. That means A's sides are 2 cm.

So, the area of square B is 4^2 = 16 cm^2, and A's area is 4 cm^2. We can see the shaded area is half of A, so it's 2 cm^2.

What percent of 16 is 2?

2 / 16 * 100 = 12.5%

Which of the following appear in the diagram below? Check all that apply. X Z. W O A. _XYZ B. ZYXZ C. w D. YX

iren2701 [21]

Answer:

A, C, and D.

Step-by-step explanation:

<XYZ appears in the diagram as the vertex angle Y, has two sides, YW and YX that intersect at point Y to form <XYZ.

Thus, <XYZ, line segments YW and YX all appear in the diagram given.

<YXZ does not appear because there's no vertex angle labelled X.
