((12-4)(3-2))^2 + square root of 64
Answers
Answer: 72
Step-by-step explanation: First step that I did was to subtract 12 and 4 to get 8. I then subtracted 3 and 2 to get 1. Then since 8 and 1 are in the parenthesis, I multiplied 8 and 1 to get 8. 8 to the 2nd power then comes out to 64. 64 adding the square root of 64 which is 8 then comes out to 64 plus 8 because the square root of 64 is 8. 64 plus 8 equals 72.

Camilo uses 32 ounces of filling to make empanadas de queso. He puts 8 empanadas on each of 3 trays. Write a fraction to show how many ounces of filling Camilo uses in each empanada.
Answers
Answer: The fraction that will show the number of ounces of filling Camilo uses is x = 32 ounces
Step-by-step explanation:
Calculation by using fractions method :
The number of ounces used is x = 32
The number of trays = 3
Number of empanadas on each tray = 8
Therefore, the total number of empanadas on the 3 trays
= 3×8
= 24
If x = empanadas
32 ounce = x
Therefore, the fraction that shows number of ounces of filling Camilo uses in each empanada is x = 32 ounces

we get that the power set of {2, 3, 4, 5} a subset of the power set of {1, 2, 3, 4, 5, 6}.
We are given a power set:
A = {1, 2, 3, 4, 5, 6}
We are also given another power set:
B = {2, 3, 4, 5}
We need to tell if B is a subset of A or not.
We can see that every element of B is a part of A as well.
So, we can say that B is a subset of A.
B ⊂ A

A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. The company wishes to test the hypothesis H0: μ = 12 against H1: μ < 12, using a random sample of four specimens. (a) What is the type I error probability if the critical region is defined as x < 11.5 kilograms? (b) Find β for the case in which the true mean elongation is 11.25 kilograms.

The Type I error's computed value is 0.02275 and The Type II error has a computed value of 0.50 based on probability.
What is probability?
The potential or opportunity of an event happening is known as probability. The probability is equal to the variety of possible outcomes. the estimated number of outcomes that could occur.(a) Type I error probability if the critical region is defined as x < 11.5 kilograms

The product of 84.12 and which number will have three decimal places?
Answers
The product of 84.12 and 19.3 will have three decimal places.
Here, we are given a number 84.12. As we can see this number has 2 decimal places. We need to find a number such that when it is multiplied by 84.12, the result has 3 decimal places.
Let us look at each option one by one,
1. 4.22
4.22 has 2 decimal places and hence if we we multiply it by 84.12, it will give us 4 decimal places. Thus, it is not the correct option.
2. 10.51
Again, 10.51 has 2 decimal places and hence if we we multiply it by 84.12, it will give us 4 decimal places. Thus, it is not the correct option.
3. 14.163
14.163 has 3 decimal places and hence if we we multiply it by 84.12, it will give us 5 decimal places. Thus, it is not the correct option.
3. 19.3
19.3 has 1 decimal place and hence if we we multiply it by 84.12, it will give us 2 decimal places. Thus, 19.3 is the correct option.

Juan and Mahdi are to run a race, but Juan can run 18 meters per second, whereas Mahdi can run 6 meters per second. If Mahdi has a 228 -meter head start, how long will it be before the faster runner catches the slower runner, if they begin at the same time? Round your answer to the nearest whole number.
Answers
Answer:
19 seconds
Step-by-step explanation:
You want to know the time it takes for Juan, running 18 m/s, to overtake Mahdi, running 6 m/s, if Mahdi has a 228 meter head start.
Closing timeThe time to close the gap between the runners will be ...
time = distance/speed
time = (228 m)/(difference in speeds) = (228 m)/(18 m/s -6 m/s)
time = (228 m)/(12 m/s) = (228/12) s = 19 s
It will take Juan 19 seconds to catch Mahdi.
