Answer:

a) The number of ants in week three is shown through the following geometric progression: 500*1.1*1.1*1.1

b) 1.21

Step-by-step explanation:

We know that 500 ants are increasing at a rate of 10% every week which means that we can calculate the week one ants like this

500*1.1

Week two

500*1.1*1.1

and so on.

We write the following equation

500(1.1)^n where n is the number of weeks

We plug in 8 and then 6 for n in the equation above and get

500(1.1)^8=1071.79

500(1.1)^6=885.78

Divide and get that p=1.21

Mazyrski [523]

Answer:

0.8413 or 84.13%

Step-by-step explanation:

Given : The mean is 72 inches and the standard deviation is 15 inches

To Find : What is the probability that in a randomly selected year, the snowfall was less than 87 inches

Solution:

Mean = \mu = 72

Standard deviation = \sigma = 15

Formula : z=\frac{x-\mu}{\sigma}

We are supposed to find the probability that in a randomly selected year, the snowfall was less than 87 inches

So, x = 87

Substitute the values in the formula

z=\frac{87-72}{15}

z=1

Now to find P(z<87) refer the z table

P(Z<87)=0.8413 = 84.13%

So, the probability that in a randomly selected year, the snowfall was less than 87 inches if the mean is 72 inches and the standard deviation is 15 inches is 0.8413 or 84.13%
