Answer:

whatever is higher than 1.5 is higher than r

Step-by-step explanation:

-1.2 ≤ -0.8r

-1.2/0.8 ≤ -0.8r/0.8

-1.5 ≤ -r

-1.5/-1 ≤ -r/-1

1.5 ≥ r

1.5 is equal to or bigger than r

In 2000, the population of a county was 25,300,987. The population decreased at a rate of 2% each year. What was the population
EastWind [94]

Answer: In 2008 the population was 21,525,144

Step-by-step explanation:

You need to use the following formula for Exponential decay:

P=P_0(1-r)^t

Where P_0 is the initial population in the year 0, r is the rate of decay and t is the time.

In this case, you can identify that:

P_0=25,300,987\\\\r=2\%\\\\t=8

Therefore, substituting these values into the formula for Exponential decay, you get:

P=P_0(1-r)^t\\\\P=(25,300,987)(1-\frac{2}{100})^8\\\\P=21,525,144

Then, in 2008 the population was 21,525,144

Out of 100 employees at a company, 92 employees either work part time or work 5 days each week. There are 14 employees who work
Alexus [3.1K]

Answer: 0.02

Step-by-step explanation:

OpenStudy (judygreeneyes):

Hi - If you are working on this kind of problem, you probably know the formula for the probability of a union of two events. Let's call working part time Event A, and let's call working 5 days a week Event B. Let's look at the information we are given. We are told that 14 people work part time, so that is P(A) = 14/100 - 0.14 . We are told that 80 employees work 5 days a week, so P(B) = 80/100 = .80 . We are given the union (there are 92 employees who work either one or the other), which is the union, P(A U B) = 92/100 = .92 .. The question is asking for the probability of someone working both part time and fll time, which is the intersection of events A and B, or P(A and B). If you recall the formula for the probability of the union, it is

P(A U B) = P(A) +P(B) - P(A and B).

The problem has given us each of these pieces except the intersection, so we can solve for it,

If you plug in P(A U B) = 0.92 and P(A) = 0.14, and P(B) = 0.80, you can solve for P(A and B), which will give you the answer.

I hope this helps you.
