Use this data in the problem below. follow the steps carefully. round to the nearest tenth.

lot 3:
week 1: 345 week 2: 340 week 3: 400 week 4: 325
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.

step 3. jim squares each deviation to remove negative signs.

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.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

45
