Novay_Z [31]

Answer:

Type II error

Step-by-step explanation:

According to the definition of type II error, the type II error arises when we wrongfully accept the null hypothesis. It means that when we accept our null hypothesis and null hypothesis is not correct then type II error arises. So according to situation we are accepting the null hypothesis that the food is safe but it is actually not safe. Hence the given situation represents type II error.

If 12% = 1000, what is the remaining 88% worth?
MrRissso [65]
Note: I am not 100% sure that this is the correct way to solve this problem. It is just my best attempt to help. 

Keep in mind that every percentage can be made into a decimal. 12% = 0.12 because 12% is also 12/100 as a fraction.

Since a percentage is the original number multiplied by the percent, you can solve this problem by dividing the number given by the percent. Be sure to turn the percent into a decimal to make it easier. Your work should look like this:

12% = 0.12

1,000 / 0.12 = 8,333.33

That is the first step. How you have to finish the problem and find what 88% is. To do this, you can simply multiply 88%, or 0.88, times the answer you get in the first part. Your work should look like this:

88% = 0.88
0.88 * 8,333.33 = 7,333.33 

Now to check your work, you can add 7,333.33 and 1,000 to see if it equal the total of 8,333.33

7,333.33 + 1,000 = 8,333.3

Since it is equal, this is your answer.

What is the value of c so that -12 and 12 are both solutions of x^2-c=108? ​
murzikaleks [220]

Answer:

c=36

Step-by-step explanation:

  1. Because x^2-c=108 can be rewritten as x^2-c-108=0, finding the value of c so that x=(+-)12 solves this equation it means to find the value of c so that (+-)12^2-c-108=0.
  2. Because 12^2=(-12)^2=144, we must find c so that 144-c-108=0.
  3. Because 144-108=36, c=36.
  4. To check, replace c=36 in the initial equation, and check  it is a solution for x=(+-)12.
