Step-by-step explanation:
Let the random variable 
denote the damage in $ incurred in a certain type of accident during a given year. The probability distribution of is given by
A company offers a $500 deductible policy and it wishes its expected profit to be $100. The premium function is given by
For 
, we have
For 
,
For 
,
For 
,
Therefore, the probability distribution of 
is given by
To determine the premium amount that the company should charge, we need to calculate the expected value of 
Therefore,
which means the $600 is the amount the should be charged.
Answer:
x=2
TU:4(2)-1=7
UB: 3
TB: 10
Step-by-step explanation:
4x-1+2x-1=5x
6x-2=5x
6x=5x+2
subtract 5x from both sides
x=2
TU: (4x-1)
4(2)-1
8-1
7
TU:4(2)-1=7
UB: (2x-1)
2(2)-1
4-1
3
UB: 3
TB: 5(2)
TB: 10

Step-by-step explanation:
<u>Explanation for part 1.</u>
To find the mean, find total then divide by number of data set
For college salaries
Sum=41+67+53+48+45+60+59+55+52+52+50+59+44+49+52=786
Number of samples=15
Mean= 786/15 =52.4 * $1000=$52400
For High school salaries
Sum=23+33+36+29+25+43+42+38+27+25+33+41+29+33+35=492
Number of samples =15
Mean= 492/15 = 32.8 *$1000= $32800
College grads make more money according to the means.
<u>Explanation for part 2.</u>
Treat the data as part of coordinates and graph then on the same scale and axis to visualize the trend and make comparison.In this case, the graph for the line of best fit is linear as attached.
0,2 because the y intercept is th middle line so you go up the line and see what number the line goes through
