Answer:
732 samples ;
752 samples
Step-by-step explanation:
Given :
α = 90% ; M.E = 0.03 ; p = 0.58 ; 1 - p = 1 - 0.58 = 0.42
Using the relation :
n = (Z² * p * (1 - p)) / M.E²
Zcritical at 90% = 1.645
n = (1.645² * 0.58 * 0.42) / 0.03²
n = 0.65918769 / 0.0009
n = 732.43076
n = 732 samples
B.)
If no prior estimate is given, then p = 0.5 ; 1 - p = 1 - 0.5 = 0.5
n = (Z² * p * (1 - p)) / M.E²
Zcritical at 90% = 1.645
n = (1.645² * 0.5 * 0.5) / 0.03²
n = 0.67650625 / 0.0009
n = 751.67361
n = 752 samples
Answer:
is the longest side in a triangle
Step-by-step explanation:
is the longest side in a triangle
1197 = 42 × h / 3 ; where h = the height of the pyramid ;
h = ( 3 × 1197 ) / 42 ;
h = 3591 / 42 ;
h = 85.5 feet ;
Answer:∠KJG and ∠FGJ
Step-by-step explanation:
Alternate interior angles are diagonal from each other and are the same value.
Answer:
x = 4
Step-by-step explanation:
the 2 given angles are corresponding angles and are congruent , then
25x = 24x + 4 ( subtract 24x from both sides )
x = 4
