A country's population in 1991 was 136 million. In 2000 it was 141 million. Estimate the population in 2016 using the exponentia

xeze [42]

Answer: The population will be about 150 million in the year 2016.

First, let's start by using the given equation. Fill in the values that you know and solve for the missing piece.

Our equation is:

141 = 136e^(9k) I used 9 because 2000 is 9 years past 1991.

(141/136) = e^9k Divide both sides by 136

ln (141/138) = 9k Take the natural log of both sides, the e is removed.

0.004 = k Find the natural log of 141/136 and divide it by 9.

Now, we have a new equation. Just plug in 25 for x and you will get 150. We used 26 because 2016 is 25 years past the starting year of 1991.

Your medical research team is investigating the standard deviation of the cost of a 30-day-supply of a certain heart medication.

Valentin [98]

Considering the situation described, the hypothesis tested are given as follows:

The null hypothesis is $H_0: \sigma \geq 23$

The alternative hypothesis is $H_1: \sigma < 23$

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if the standard deviation is not less than $23, that is:

$H_0: \sigma \geq 23$

At the alternative hypothesis, it is tested if there is significant evidence t conclude that the standard deviation is less than $23, that is:

$H_1: \sigma < 23$

How many 4/5 cup servings in 8 cups

Molodets [167]

To solve this question, we use simple division:
$\frac{8}{ \frac{4}{5} } = 8* \frac{5}{4} = \frac{40}{4} = 10$

So, there are 10 servings of 4/5 of a cup in 8 cups.

It should be just 12b, since they all have the same exponent, they can all be combined.
