Answer:
B.) C(d)= 12d+42
Step-by-step explanation:
A flat fee means it is only paid once and doesn't increase or decrease.
The gigabytes of data fluctuate how much you pay the 12 dollar amount.
Meaning 12d represents the price of data and +42 shows the flat rate.
Overall giving us the equation C(d)= 12d+42.
the two points are,
(5,4) & (7,10)
so the slope is,
so, the slope of the line is,
m = 3
Answer:
(27.954, 30.046)
Yes
Step-by-step explanation:
Given that :
Mean (m) = 29
Standard deviation (σ) = 2.2
Sample size (n) = 17
Confidence interval (α) = 95%
Average age as claimed by the company = 28
Confidence interval formula :
Mean ± (Zcritical * σ/sqrt(n))
Zcritical at 95% = 1.96
(Zcritical * σ/sqrt(n)) = (1.96 * (2.2/sqrt(17)) = (1.96 * 0.5335783) = 1.0458136
Lower boundary = (29 - 1.0458136) = 27.954186
Upper boundary = (29 + 1.0458136) = 30.045813
(27.954, 30.046)
b. Does this result lend support to the car's company's claim?
Yes, it does, 28 falls in between the the calculated confidence interval.
Circumference of a circle:
C = 2 r π;
Length of an arc:
L = r π α / 180°
L = r π · 30° / 180° = r π /6
r π /6 : 2 r π = 1/6 : 2 = 1/12
Answer: A ) 1/12
