the answer is D.
because you have to make the denominators the same so you have to multiply 3 until it gets to 15 and 3x5 is 15 and whatever you do to the denominator you have to do to the numerator

Answer:
Not a function
Step-by-step explanation:
there's two 9's
Based on the current population and the rate of decrease, the population in five years will be 81,537 people.
<h3>What is the population in five years?</h3>
This can be found by the formula:
= Current population x ( 1 - rate) ^ number of years
Solving gives:
= 100,000 x ( 1 - 4%)⁵
= 100,000 x 0.8153726976
= 81,537 people
In conclusion, option B is correct.

Answer:
The null and alternative hypothesis are:
This is a left tailed test.
Step-by-step explanation:
A hypothesis test is to be performed to determine whether last year's mean local monthly bill for cell phone users has decreased from the 2001 mean of $47.79.
Then, the claim that will be expressed in the alternative hypothesis is that the monthly bill is lower than $47.79.
The null hypothesis will state that the monthly bill does not differ significantly from $47.79.
Then, the null and alternative hypothesis are:
As we only want to test if its lower, we are interested only in the left tail of the distribution. We want to know if the test statistic is below the critical value to conclude if we have evidence for our claim. This is then a left tailed test.
Answer:
9/5
Step-by-step explanation:
Convert the mixed number 145 into an improper fraction first by multiplying the denominator (5) by the whole number part (1) and add the numerator (4) to get the new numerator. Place the new numerator (9) over the old denominator (5)
