Answer:

Below.

Step-by-step explanation:

I'll do number 20, 21, 22 for you.

20. It is ±1, ±2, ±4, ±8.

21. Reflected over the x-axis and down 4.

22. Common ratio = 25/5 = 5.

23. Imaginary roots occur in pairs so there is also a root -5i.

The answer is c.

19. Option (a).

This is a translation of 4 to the left ( due to the (x + 4).

If x =2 find the value of q in the equation 3x-4=x+q

Effectus [21]

Step-by-step explanation:

given x=2

and the equation

$3x - 4 = x + q$

to find the value of q , you need to make q the subject in the equation as shown below

q= 3x-x -4

q=2x-4

but x= 2

so just substitute the value of x in the equation for the q

$q = 2(2) - 4$

q=4-4

q=0

therefore the value of q is 0

Follow these steps:

-8.4b - 4.2 = 12.6

Add 4.2 on both sides:

-8.4b = 16.8

Divide by -8.4 on both sides to give you the final answer of:

b = -2

So you're answer is indeed correct! Hope this helps and that the steps are clear enough!

In 2008, data from the Center for Disease Control revealed that 28.5% of all male teenagers, aged 18-19 and attending U.S. colle

m_a_m_a [10]

Answer:

a) H0 : u = 28.5%

H1 : u < 28.5%

b) critical value = - 1.645

c) test statistic Z= - 1.41

d) Fail to reject H0

e) There is not enough evidence to support the professor's claim.

Step-by-step explanation:

Given:

P = 28.5% ≈ 0.285

X = 210

n = 800

$p' = \frac{X}{n} = \frac{210}{800} = 0.2625$

Level of significance = 0.05

a) The null and alternative hypotheses are:

H0 : u = 28.5%

H1 : u < 28.5%

b) Given a 0.05 significance level.

This is a left tailed test.

The critical value =

$-Z_0.05 = -1.645$

The critical value = -1.645

c) Calculating the test statistic, we have:

$Z = \frac{p' - P}{\sqrt{\frac{P(1-P)}{n}}}$

$Z = \frac{0.2625 - 0.285}{\sqrt{\frac{28.5(1-28.5)}{800}}}$

Z = -1.41

d) Decision:

We fail to reject null hypothesis H0, since Z = -1.41 is not in the rejection region, <1.645

e) There is not enough evidence to support the professor's claim that the proportion of obese male teenagers decreased.
