Karen will be payed $60 in interest in the first four years. 

We can solve this problem by using the simple interest formula (Interest = Principal * Rate * Time)

Interest = 300 * 5/100 * 4

Interest = 60, meaning that Karen will be payed $60 in interest in the first four years.

A paint manufacturer discovers that the mean volume of paint in a gallon-sized pail is 1 gallon with a standard deviation of 0.0
Agata [3.3K]

Answer:

Approximately 68%.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 1, standard deviation = 0.05.

Estimate the percent of pails with volumes between 0.95 gallons and 1.05 gallons.

0.95 = 1 - 0.05

1.05 = 1 + 0.05

So within 1 standard deviation of the mean, which by the Empirical Rule, is approximately 68% of values.

Nana76 [90]

Answer:

0.0000007

And if we count the number of zeros before the number 7, we can rewrite the number like this:

7x10^{-7}

We cansolve this problem also counting the number of positions that we need to move the decimal point to the right in order to obtain the first number (7)

And the best option would be:

B. 7 x 10-7

Step-by-step explanation:

For this case we have the following number given:

0.0000007

And if we count the number of zeros before the number 7, we can rewrite the number like this:

7x10^{-7}

We cansolve this problem also counting the number of positions that we need to move the decimal point to the right in order to obtain the first number (7)

And the best option would be:

B. 7 x 10-7
