Answer:

21.75

Step-by-step explanation:

Plugging in the variables, you'd get 24 - (20-4) over (4 + 4). Add the contents of the parenthesis and you'd get 24 - (18)/(8). You'd divide, and get 24- 2.25, or 21.75.

If you aren't supposed to simplify on this assignment, it would probably be 24 - 18/8, or if you use fractions 21 and 3/4.

This is an exponential equation that can be represented by the following:

f(x) = a(b)^x

In this case...

25143 = a(0.66)^3

25143 is the population after 3 hours.

3 is the amount of time in hours.

0.66 represents the percent of the population remaining after each hour (66% as there is a 34% decline each hour).

We must solve for a, which is the initial population.

First, simplify (0.66)^3 to 0.2874.

25143 = 0.2874a

Now divide both sides by 0.2874 to isolate a.

a = 87455

There were initially 87,455 people within the city. I wouldn't want to be in that place!

Math Question:<br> Pls help I will do anything
kow [346]

Answer:

The probability of spinning red is \frac{1}{3}, the probability of spinning a 1 is \frac{1}{6}, the probability of spinning an odd number is \frac{1}{2}, and the probability of spinning a 9 is 0.

Step-by-step explanation:

Since there are a total of 6 possible outcomes, you can use this in the following questions. There are 2 red tiles, so the probability of spinning red is \frac{2}{6} or \frac{1}{3}. Since there are only one 1 tile, the probability of spinning a 1 is \frac{1}{6}. Since there are three odd numbers, the probability of spinning an odd number is \frac{1}{2}. Since there are no 9 in the spinner, the probability of spinning a 9 is 0 or never.

Whenever the population standard deviation is unknown, which distribution is used in developing an interval estimate for a popul
r-ruslan [8.4K]

Answer:

The t-distribution is used.

Step-by-step explanation:

When we dont know the standard deviation of the population, we use the t-distribution(t-table).

Otherwise, the z-distribution(z-table) is used.

So the answer to this question is the t-distribution.
