Answer: 49.5 ~50
Step-by-step explanation: 132/8=16.5 16.5(3)=49.5
Answer:
C(n) = pn
Step-by-step explanation:
Given :
n = time in hours for service call
C = total cost
Total cost = unit cost per hour * time in hours
If unit cost per hour = p
Hence,
C(n) = p * n
C(n) = pn
A) The mean of set 1 is 53,800, while the mean of set 2 is 38,600. The median of set 1 is 42,000, while the median of set 2 is 28,000.
B) The median is a more accurate estimate, because each set has 1 particularly large outlier which heavily skews the mean. In each set, the mean is actually higher than 4 out of the 5 data points, which is not very accurate in describing how much the typical car costs.
To solve use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
REMEMBER: IF A STEP IS NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .
14 + 18 ÷ 2 x 18 - 7
Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right. In this case that would be division first then multiplication.
NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression
Division
14 + 18 ÷ 2 x 18 - 7
18 ÷ 2 = 9
14 + 9 × 18 - 7
Multiplication
14 + 9 × 18 - 7
9 × 18 = 162
14 + 162 - 7
Addition
14 + 162 - 7
14 + 162 = 176
Subtraction
176 - 7
= 169

The y-intercept of f(x) = 5x - 45 would be -45, as that is what is represented in the equation. The way to find the x-intercept would be to solve the equation when f(x) = 0.
0 = 5x - 45
+ 45 + 45
45 = 5x
/5 /5
9 = x
And there we have it.
The intercepts of f(x) = 5x - 45 are as follows:
y-intercept = -45
x-intercept = 9
Hope that helped =)
