The interpretation of the slope in the context of the problem is: For every hour the electrician works, her pay will increase $28.
<h3>How to Interpret the Slope of a Function?</h3>
The slope of any function is the unit rate or average rate of change of the given function for that situation.
Given the function, E(x) = 130 + 28x, where:
E(x) is the amount an electrician charges per job
130 is the flat rate service which is the starting value or y-intercept
28 is the unit rate or slope, which is the fee charged per hour by the electrician to complete a job.
Thus, the interpretation of the slope in the context of the problem is: For every hour the electrician works, her pay will increase $28.

Answer:
x = 39.1
Step-by-step explanation:
<u>Points to remember</u>
Mean of a data set is given by
Mean = (sum of data set)/Total number of data
<u>To find the value of x</u>
It is given a data set
31.7, 42.8, 26.4, x
Mean = 35
Sum of data set = 31.7 + 42.8 + 26.4 + x = 100.9 + x
(100.9 + x)/4 = 35
100.9 + x = 35 * 4 = 140
x = 140 - 100.9 = 39.1
Therefore x = 39.1
When its to the negative power, you have to find the reciprocol in order to remove the negative exponent. so e^-3, which is equivilant to e^-3/1, is equal to 1/e^3. Then divide and the answer is 0.049
