Answer:

D. 22

22 is in the middle

There are three numbers on both sides of 22 so it makes it even and 22 ends up being in the middle.

Hope this helps

Help me solve 4= 3a - 14

malfutka [58]

For this all you need is to balance the equation out with the variables (a) on one side and the number on the other. Also remember that what you do to one side you do to another. So here we have 4=3a-14. You should add the 14 to both sides, on one side to cancel out the 14 and add the 14 on the other side to balance it out. Now you have 18=3a. Divide by 3 on both sides to isolate the variable a and you have your answer. A=6

State the null and alternative hypotheses to test if the population represented by Sample 1 has a mean that is 2.0 units higher

avanturin [10]

Answer:

Null Hypothesis, $H_0$ : $\mu_A-\mu_B$ = 2.0 units or $\mu_D$ = 2.0 units

Alternate Hypothesis, $H_A$ : $\mu_A-\mu_B\neq$ 2.0 units or $\mu_D\neq$ 2.0 units

Step-by-step explanation:

We are given the following data below and we have test if the population represented by Sample 1 has a mean that is 2.0 units higher than the population represented by Sample 2;

Pair : 1 2 3 4 5 6 7

Sample1 : 5 6 10 3 6 7 8

Sample2 : 4 4 3 5 5 5 3

Let $\mu_A$ = population mean represented by Sample 1

$\mu_B$ = population mean represented by Sample 2

$\mu_D$ = population mean matched-pair differences for Sample 1 - Sample 2

So, Null Hypothesis, $H_0$ : $\mu_A-\mu_B$ = 2.0 units or $\mu_D$ = 2.0 units

Alternate Hypothesis, $H_A$ : $\mu_A-\mu_B\neq$ 2.0 units or $\mu_D\neq$ 2.0 units

Here null hypothesis states that the population represented by Sample 1 has a mean that is 2.0 units higher than the population represented by Sample 2.

On the other hand, alternate hypothesis states that the population represented by Sample 1 has a mean that is not 2.0 units higher than the population represented by Sample 2.

How do you solve the inequality 6y+3> -18x

Alex17521 [72]

$6y + 3 \ \textgreater \ - 18 x$

Subtract 3 from both sides:

$6 y + 3 - 3 \ \textgreater \ - 18 x - 3$

$6y \ \textgreater \ - 18 x - 3$

Dividade both sides by 6 :

$\frac{6y}{6} \ \textgreater \ \frac{-18x-3}{6}$

$y \ \textgreater \ \frac{-18x-3}{6}$

hope this helps!
