Answer:

Eric's earning is $7

Step-by-step explanation:

Given

Represent Robert's earnings with R and Eric's with E.

R = 10\\R = 2E - 4

Required

What is the value of E?

Substitute 10 for R in the second equation.

10 = 2E - 4

Solve for 2E

2E = 10 + 4

2E = 14

Solve for E

E = 14/2

E = 7

<em>Eric's earning is $7</em>

Red, green, and white jellybeans are combined in a ratio of 5:4:3, respectively. What is the ratio of green jelly beans to the t
Rainbow [258]

We have been given that red, green, and white jellybeans are combined in a ratio of 5:4:3 respectively. We are asked to find out the ratio of green jelly beans to the total number of jelly beans.

In order to find out  the ratio of green jelly beans to the total number of jelly beans we have to find out the total number of jelly beans.

\text{Total number of jelly beans}=5+4+3=12

Now we can find out out our desirable ratio by substituting our finding in the ratio.

\text{Number of green jelly beans}:\text{Total number of jelly beans}=4:12\\=1:3

Therefore, ratio of green jelly beans with respect to all jelly beans is 1:3.

Suppose the dealer incentive per vehicle for honda's acura brand in 2012 is thought to be bell-shaped and symmetrical with a mea
andreev551 [17]

Answer:

From $1600 to $3400.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed 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 = 2500

Standard deviation = 300

What interval of dealer incentives would we expect approximately 99.7% of vehicles to fall within?

By the Empirical Rule, 99.7% fall within 3 standard deviations frow the mean. So

From 2500 - 3*300 = 1600 to 2500 + 3*300 = 3400.
