The answer to your question is:
Step-by-step explanation:
Data
a)
C (0, 0)
D (7, 12)
m = (12 - 0) / (7 - 0)
m = 12/7
Slope = 12/7
b)
(y - y1) = m(x - x1)
(y - 12) = 12/7 (x - 7)
y - 12 = 12/7 x - 1
y = 12/7 x - 1 + 12
y = 12/7 x + 11
c)
Domain [0, 7]
Range [0, 12]
Answer:The answer is B
Step-by-step explanation:
Answer:
mean ≈ 25.45
Step-by-step explanation:
mean is calculated as
mean = 
We require the sum for both classes
class A
mean = 
= 40 ( multiply both sides by 9 )
sum = 9 × 40 = 360
class B
mean = 
= 20 ( multiply both sides by 24
sum = 24 × 20 = 480
Total sum for both classes = 360 + 480 = 840 , then mean for both classes is
mean = 
≈ 25.45 ( to 2 dec. places )
