kompoz [17]

Answer:

2011

Step-by-step explanation:

Here is the formula.

A=P(1+r)^{n}

A = Final Value

P = Starting Value

R = Rate

N = Time in Years

A = 8,000,000,000

P = 5,400,000,000

R = 0.0195

N = Time in Years

Solve for n.

20.35 Years from 1990; so sometime in 2011 the population would be 8 billion.

A pizza shop sells three sizes of pizza, and they track how often each size gets ordered along with how much they profit from ea
777dan777 [17]

Answer:

The mean and standard deviation of Y is $6.56 and $2.77 respectively.

Step-by-step explanation:

Consider the provided information.

Let Y represent their profit on a randomly selected pizza with this promotion.

The company is going to run a promotion where customers get $2 off any size pizza.

Therefore, Y=\text{Profit}-\$2

Y=X-\$2

So the mean will be reduced by 2.

\mu_Y=\mu_X-\$2

\mu_Y =\$ 8.56 - \$2

\mu_Y =\$6.56

If we add or subtract any constant number from a given distribution, then the mean is changed by the same number(i.e constant number) but the standard deviation will remain the same.

Therefore \sigma_Y=\sigma_X=2.77

Hence, the mean and standard deviation of Y is $6.56 and $2.77 respectively.

BaLLatris [955]
To calculate the mean absolute deviation, you first must find the mean of the data and then find the difference between each piece of data and the mean.

Please see the attached picture for the work.

The mean absolute deviation is approximately 1.48.

This means that the numbers of candies in the 10 bags are all very close to one another. There is not much variation.
