(40,25.20)(72,21.36)
slope = (21.36 - 25.20) / (72 - 40) = -3.84 / 32 = -0.12
y = mx + b
slope(m) = -0.12
(40,25.20)...x = 40 and y = 25.20
sub and solve for b, the y int
25.20 = -0.12(40) + b
25.20 = - 4.8 + b
25.20 + 4.8 = b
30 = b
ur equation is : y = -0.12x + 30....where x is ur minutes, and y is remaining credit.
after 86 minutes...
y = -0.12(86) + 30
y = - 10.32 + 30
y = 19.68 <===

Answer:
Sample size is
Step-by-step explanation:
Given that,
Margin of error %
Confidence level %
Suppose, sample proportion
i.e.
We know that,
Margin of error
∴
squaring on both side,
∴
Hence, the sample size is,
Hence, the correct option is
