2x - 4y = 8 → -4y = -2x + 8 → y = - 2
We know the slope (m) = 4, need to find y-intercept (b)
y = 4x + b
- 2 = 4x + b
- 2 = 4(6) + b
3 - 2 = 24 + b
1 = 24 + b
-23 = b
Equation: y = 4x - 23
Answer: C
Answer:
The minimum sample size 'n' = 862.538
Step-by-step explanation:
<u><em> Step(i)</em></u>:-
Given the percentage of students favoring a four-day school week during May and June of every school year is approximately 85%
Given the Proportion of students favoring a four-day school week during May and June of every school year
p = 85% = 0.85
q = 1-p = 1-0.85 = 0.15
Given Margin of error = 2 % or 0.02
Level of significance = 0.90 or 0.10
The critical value Z₀.₁₀ = 1.645
<u><em>Step(ii)</em></u>:-
The Margin of error is determined by
Cross Multiplication, we get
√n = 29.369
squaring on both sides, we get
n = 862.538
<u><em>Final answer:</em></u>-
<em>Sample size 'n' = 862.538</em>
