Answer:

C. 1.18b

Step-by-step explanation:

Hi! Ace here!

In order to do this, we have to convert 18% into a decimal.

The decimal form of it is .18.

So we have to do

b+.18b

Combine like terms:

1.18b

I hope this helped

Answer:

1.18b

Step-by-step explanation:

Remember: percentage = decimal × 100

total = b + 18% x b

Factor out b:

total = b x (1 + 18%) = b x (1 + 0.18)

total = b x 1.18 = 1.18b

If f(x)=(3+x)/(x-3), what is f(a+2)?
tigry1 [53]

Answer:

To answer items such as this, we directly substitute the a + 2 to the all the x's in the function such that,

                           f(a + 2) = (3 + a + 2) / (a + 2 - 3)

Simplifying the function generated above,

                           f(a + 2) = (5 + a) / (a - 1)

If the rejection region is +1.10, what will be your decision if the z computed value is 2.34
IRINA_888 [86]

The decision when the z value is within the rejection region is that we'll have to reject the null hypothesis.

<h3>What is a rejection region?</h3>

It should be noted that the rejection region is also known as the critical region. It is the set of values where the null hypothesis is rejected.

When the observed test statistic is in the rejection region, we'll have to reject the null hypothesis and then accept rte alternative hypothesis.
