Answer: n = 14
Step-by-step explanation: margin of error = critical value × σ/√n
Where σ = population standard deviation = 1
n = sample size = ?
We are to construct a 99% confidence interval, hence the level of significance is 1%.
The critical value for 2 tailed test at 1% level of significance is gotten from a standard normal distribution table which is 2.58
Margin of error = 0.7
0.7 = 2.58×1/√n
0.7 = 2.58/√n
By cross multipying
0.7×√n = 2.58
By squaring both sides
0.7^2 × n = 2.58^2
0.49 × n = 6.6564
n = 6.6564/0.49
n = 14
F(2) = (5/2)f(1) = 8.0
f(3) = (5/2)f(2) = 20
f(4) = (5/2)f(3) = 50
f(5) = (5/2)*50 = 125

Answer:
h=7
Step-by-step explanation:
may be rewritten as
as adding a negative is the same as subtracting a positive.
To solve, add 3 to both sides.
Answer:
x = 25°
Step-by-step explanation:
The sum of the interior angles of a triangle = 180°
180° = 35° + x° + x + 95°
2x° = 50°
x = 25°
