Answer:
a) (0.576, 0.624)
Step-by-step explanation:
Given that the sample proportion (p) = 60% = 0.6, sample size (n) = 900, confidence (C) = 85%
α = 1 - C = 1 - 0.85 = 0.15
α/2 = 0.075
The z score of α/2 (0.075) corresponds with the z score of 0.425 (0.5 - 0.075) which is equals to 1.44, hence 
The margin of error (E) is:
The confidence interval = p ± E = 0.6 ± 0.024 = (0.576, 0.624)
Answer:
39°
Step-by-step explanation:
For a straight line, the sum of angle is 180°
At the point where we have the 107°, the inner angle in the triangle will be 180-107=73°
68° is alternate angle to the inner angle in the triangle
Since the sum of angles in a triangle are 180°, then angle x will be
X=180-73-68=39°
Therefore, missing angle is 39°
Answer:
n=8
Step-by-step explanation:
2(5-6n)=10n-166
1) Distribute the 2 to 5 and -6n:
10-12n=10n-166
2) Add 166 to both sides:
176-12n=10n
3) Add 12n to both sides:
176=22n
4) Divide both sides by 22:
n=8

Answer:
Step-by-step explanation:
You and your friends = 4
Appetizers = 8*3 $ (3 appetizers)
Deserts = 4*2 $ (2 deserts)
Bill = 8*3 + 4*2
= 24 + 8
= 32 $
Each pays equally
= 32 / 4. ( 4 people are there)
= 8
So, you and your friends need to pay 8$ each to pay bill
