Answer:

total balloons = 120r+72y

Step-by-step explanation:

If there are 120 cases of red balloons and r red balloons in each cases

Number of red balloons = 120*r

If there are 72 cases of yellow balloons and y yellow balloons in each cases

Number of yellow balloons = 72y

The total number of balloons is red balloons plus yellow balloons

total balloons = 120r+72y

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

Doss [256]

Answer:

Using the Empirical Rule, we find that .997 (99.7%) of students have grade point averages that are between 1.23 and 3.81.

Step-by-step explanation:

Calculate the z-scores corresponding to a GPA of 1.23 and 3.81.

$\displaystyle z=\frac{1.23-2.52}{.43} = \frac{-1.29}{.43}= -3$
$\displaystyle z=\frac{3.81-2.52}{.43}= \frac{1.29}{.43} =3$

We want to find the area between the z-scores of -3 and 3.

The Empirical Rule tells us that 99.7% of the data lies within three standard deviations under the normal curve.

Therefore, the area between -3 < z < 3 is about .997, or around 99.7%.
