The unit price for the electrical wire is $0.041 per inch which i found by dividing the price by the length which i converted to inches to avoid decimals with the second one. $1.49/36in =$0.041per inch. The second one is $0.69/18in =$0.038 which makes the second one a better deal

1.49/3

0.5 dollars per feet.

This is a fraction equal to 1.49/3.

We want a unit rate where 1 is the denominator, so we divide the top and bottom by 3.

The answer is 0.49666667, which can be rounded to 0.5

Citrus2011 [14]

17.9:13

Step-by-step explanation:

I know this because in order to find the percentage of 310, you must mutiply 310 by the percentage.

The number of students who like basketball:

310 x 0.05774 = 17.9

The number of students who don't like basketball:

310 x 0.04726 = 13

Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.5
iris [78.8K]

Answer:

By the Empirical Rule, 99.7% of the students have grade point averages that are between 1.28 and 3.8.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed(bell-shaped) random variable:

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

95% of the measures are within 2 standard deviation of the mean.

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

In this problem, we have that:

Mean = 2.54

Standard deviation = 0.42.

Between 1.28 and 3.8?

1.28 = 2.54 - 3*0.42

So 1.28 is 3 standard deviations below the mean

3.8 = 2.54 + 3*0.42

So 3.8 is 3 standard deviations above the mean

By the Empirical Rule, 99.7% of the students have grade point averages that are between 1.28 and 3.8.
