Answer:

A,B,D

Step-by-step explanation:

Answer:

x = 40

Step-by-step explanation:

(x × [tex]\frac{1}{5}[/tex] )+ 24 = [tex]\frac{8}{10}[/tex] × x

0.2x + 24 = 0.8x

0.2x - 0.2x + 24 = 0.8x - 0.2x

24 = 0.6x

0.6x = 24

0.6x × [tex]1\frac{2}{3}[/tex] = 24 × [tex]1\frac{2}{3}[/tex]

x = 40

Answer:

x=40

Step-by-step explanation:

1/5x+24=8/10x

give like denominators

2/10x+24=8/10x

subtract 2/10x on both sides

24=6/10x

divide 24 by 6/10, or multiply by 10/6

x=240/6

refine/simplify

x=40

Answer:

A≈50.27

Diameter = 8

Using the formulas

A=πr2

d=2r

Solving forA

A=1

4πd2=1

4·π·82≈50.26548

Answer:

I think it would be 50.24

Step-by-step explanation:

Here's what I did:

1. Diameter = 8 so radius = 4

2. 4 to the second power is 16

3. 16 × 3.14 = 50.24

I'm not sure if what I did is correct, but I hope this helps! :)

Answer:

Based on the data, if we find moderate/strong evidence against the null hypothesis and conclude the mean arsenic level of the water is greater than 8.0 ppb, we have made ____________.

a correct decision.

Step-by-step explanation:

Since there is enough evidence to conclude that the mean level of arsenic is greater than 8.0 ppb, the correct decision has been made.  There is no type I or type II error.   The type I error (called a false positive) occurs if we reject the null hypothesis when it is true.   Since we have simply rejected the null hypothesis when the alternate hypothesis is true, and the null hypothesis should be rejected, a correct decision has been made.

Answer:

decision

Step-by-step explanation:

Based on the data, if we find moderate/strong evidence against the null hypothesis and conclude the mean arsenic level of the water is greater than 8.0 ppb, we have made decision

Answer:

166.67 is answer of this question

Answer:

42in²

Step-by-step explanation:

So, it's area time, the formula for the area of a trapezoid is (base + base) ÷ 2 x height, so:

5 + 9 = 14

14 ÷ 2 = 7

7 x 6 = 42

So the area of the trapezoid is 42in²

hope this helps:)
