Answer:
The Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.
Step-by-step explanation:
Given data
Let no. of sales = x
Jonathon earning = $ 1500 + 
Raymond earning = $ 1200 + 
Given that the earnings of Jonathon & Raymond are same.
1500 +
= 1200 + 
300 = 
x = 6000 sales
Therefore the Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.
ANSWER

EXPLANATION
We can use any two points to determine the slope.
The line passes through;
(-3,1) and (-5,5).
The slope is given by

This implies that;


We can now find the equation using the formula;


Expand:


When it's 5th to the power you do the number by itself how many times the power is so the correct way would be
10×10×10×10×10

Step-by-step explanation:
In statistics, the empirical rule states that for a normally distributed random variable,
- 68.27% of the data lies within one standard deviation of the mean.
- 95.45% of the data lies within two standard deviations of the mean.
- 99.73% of the data lies within three standard deviations of the mean.
In mathematical notation, as shown in the figure below (for a standard normal distribution), the empirical rule is described as

where the symbol
(the uppercase greek alphabet phi) is the cumulative density function of the normal distribution,
is the mean and
is the standard deviation of the normal distribution defined as
.
According to the empirical rule stated above, the interval that contains the prices of 99.7% of college textbooks for a normal distribution
,

Therefore, the price of 99.7% of college textbooks falls inclusively between $77 and $149.
