Answer:
They need to wash 72 cars
Step-by-step explanation:
2000 - 1640 = 360
360/5 = 72
Answer:
The probability is of 0.1404 or 14.04%.
Step-by-step explanation:
The Poisson Distribution formula is given by:
Where:
,
is Euler's constant,
is the number of successes of which we're trying to calculate the probability of occurring.
In this exercise we have that:
.
Replacing in the formula we get:
Therefore the probability of three customers shopping at the store in an hour is of 0.1404 or 14.04%.

Answer:
The equation of the linear function that best fits the data is,
<em>y</em> = 18.66<em>x</em> + 66.87.
Step-by-step explanation:
The line of best is of the form: <em>y</em> = <em>mx</em> + <em>b</em>.
Here, <em>m</em> = slope of the line and <em>b</em> = intercept.
The formula to compute the intercept and slope are:
Consider the table below for the values of <em>∑ X, ∑ Y, ∑ X² </em>and <em>∑ XY</em>.
Compute the value of intercept and slope as follows:
The line of best fit is:
Thus, the equation of the linear function that best fits the data is <em>y</em> = 18.66<em>x</em> + 66.87.
Answer:
A. This is a linear function because there is a common difference of 2
Step-by-step explanation:
Differences are ...
The differences of 2 are common, so this is an arithmetic function.
