This is a weighted average basically take the percentages and multiply them by the amount. The total sum is the amount you will make.
0.4(-25000) + 0.25(0) + 0.35(40000)
-10000 + 0 + 14000
4000 is the expected value
If r is the cost of repairs, then the inequality is:
r > 50

Step-by-step explanation:
Step-by-step explanation:
The given data set is:
Week 1: 600
Week 2: 300
Week 3: 500
Week 4: 900
The following are the steps to find the standard deviation:
Step 1. Jim enters the data and calculates the average or mean.
Step 2. Jim calculates the deviation from the mean by subtracting the mean from each value.
Data value (x)
600 25
300 -275
500 -75
900 325
Step 3. Jim squares each deviation to remove negative signs.
Data value (x)
600 625
300 75625
500 5625
900 105625
Step 4. Jim sums the squares of each deviation and divides by the count for the variance.
Step 5.Jim takes the square root of the variance to find the standard deviation.
