Answer:
23
Step-by-step explanation:
From the graph, derive the best fit equation :
Using the points ;
(0,2.5) (100 ,35)
x1 = 0 ; y1 = 2.5 ; x2 = 100 ; y2 = 35
Slope formula, m = (y2-y1)/(x2-x1)
m = (35-2.5)/(100-0)
m= (32.5)/100
m = 0.325
The y intercept, value on the graph where best fit line crosses the y axis = 2.5
The equation :
y = mx + c
c = intercept ; m = slope
y = 0.325x + 2.5
y = Number of cars
x = number of customers
The number of customers if there are 10 cars parked :
10 = 0.325x + 2.5
10 - 2.5 = 0.325x
7.5 = 0.325x
x = 7.5 / 0.325
x = 23.076
x = 23

Answer:
D or 6
Step-by-step explanation:
Angle G is bisected if FGHI is a square. That being the case
7x + 3 = 45 Subtract 3 from both sides
7x = 45 - 3 Combine
7x = 42 Divide by 7
7x/7 = 42/7
x = 6
Answer:
$15.35104
Step-by-step explanation:
Step 1
Calculate how much is 7.2% raise
$14.32 × 7.2%
= $14.32 × 7.2/100
=$ 1.03104
Step 2
Jack's hourly rate after his raise is
$14.32 + $ 1.03104
= $15.35104
