Answer:
C. 3.2
Step-by-step explanation:
Heights of dogs: 10, 22, 15, 12, 16
✔️Find the mean of the data set =
✔️Find |data value - mean|:
|10 - 15| = 5
|22 - 15| = 7
|15 - 15| = 0
|12 - 15| = 3
|16 - 15| = 1
✔️Find the sum of |data value - mean| and divide by 10:
✅M.A.D = 3.2
Answer:
Part A : E = 35h + 200
Part B : The per hour charges of the technician is $35/hour.
Step-by-step explanation:
The technician observes that his earnings are a linear function of the number of hours he works during the month. The technician finds that when he works 55 hours during the month, he earns $2,125 and when he works 30 hours, he earns $1,250 .
If we consider the number of hours that he works in a month is h and the amount he earns in dollars is E, then (30,1250) and (55,2125) are the two ordered pairs.
Part A : Therefore, the linear function to model the relationship between the number of hours worked and the money earned will be
⇒ E - 2125 = 35(h - 55)
⇒ E - 2125 = 35h - 1925
⇒ E = 35h + 200
Part B : The equation above is in the slope-intercept form and the slope is 35 which means that the per hour charge of the technician is $35/hour. (Answer)
Answer:

Step-by-step explanation:
(1)
Given
= - 0.3
Since n is divided by 5 then use the inverse operation, multiplication.
Multiply both sides by 5 to clear the fraction
n = 5 × - 0.3 = - 1.5
(2)
Given
- 2n = 4 ← change to an improper fraction
- 2n =
Since n is multiplied by - 2 then use the inverse operation, division.
Divide both sides by - 2
n = = -
