Answer:
The probability that the sample proportion will be at least 3 percent more than the population proportion is 0.6157
Step-by-step explanation:
We need sample proportion between 0.75 - 0.03 = 0.72 and 0.75 +0.03 = 0.78. Here we have p = 0.75 and n= 158.
So z-score for sample proportion q = 0.72
z = 
= 
= - 
= - 0.872
So z-score for sample proportion q = 0.78
z= = 
= = 0.872
Therefore the probability that the sample proportion will be within 3 percent of the population proportion is
P( 0.72 < q < 0.78) = P ( -0.872 < z < 0.872)
= P( z < 0.872) - P( z < -0.872)
= 0.80785 - 0.19215
= 0.6157
Answer: The answer would be $50. Hope this helps :)

Answer:
72
Step-by-step explanation:
There are 12 inches in a foot.
Therefore in 8 feet there are 96 inches
Therefore the square floor is 96 * 96.
Therefore the area of the square floor is 9216 inches squared.
Each tile is 8 inches by 8 inches meaning it has an area of 64 inches squared.
9216 / 64 = 144.
Therefore 144 tiles are needed to tile the floor
Since each tile is 50 cents, 144 * 0.5 = 72
Therefore it costs 72 dollars to tile the floor.
Depends... is it an Iphone? Lol, just kidding.
So, for as long as he's been watching the NFL series on Cartoon Network, Joe has used 32% of his battery and he spent 4 hours watching TV. So, every 4 hours he spends watching TV, he uses 32% battery. You divide 4 by 32, and you should get 12.5. The original equation looks like this:
y = 4/0.32
Now you have 12.5 = 4/0.32.
Answer: Joe spends 12.5 hours of watching Rick and Morty if his battery was full.
Lol, I'm just random. Don't mind me.
