Give me the brainliest if u like the answer
f(x)•g(x) = (5x+7)×(x-9)
now multiply 5x with both terms and 7 with both terms
Answer:6
Step-by-step explanation:
5 times 2h is 10h, so then you have to find 5 times what is 30, and 5 times 6 is 30. So your anwser would be 6.
Answer:
The volume is 356 
, which agrees with the second answer option listed.
Step-by-step explanation:
Recall that the volume of a pyramid is the product of the area of its base(B) times the pyramid's height (h), divided by three:
For our case, the area of the base "B" is the area of a square of side = 8 inches. That is the area B is:
Now we can include this value and the value of the pyramid's height (h=12 in) in the formula for the volume to give the answer:
Answer:
We want to reduce type II error we carry out the test using a larger significance level (such as 0.10) and not a small significance level α (such as 0.01).
Step-by-step explanation:
Type I error
- Rejecting the null hypothesis when it is in fact true is called a Type I error.
- It is denoted by alpha, α that is the significance level.
- Lower values of alpha make it harder to reject the null hypothesis, so choosing lower values for alpha can reduce the probability of a Type I error.
It is given that the consequences of a Type I error are not very serious, but there are serious consequences associated with making a Type II error.
Type II error
- This is the error when we fail to reject a false null hypothesis or accept a null hypothesis when it is true.
- Higher values of alpha makes it easier to reject the null hypothesis.
- So choosing higher values for alpha can reduce the probability of a type II error.
- The consequence here is that if the null hypothesis is true, increasing the value of alpha makes it more likely that we make a Type I error.
Since, we want to reduce type II error we carry out the test using a larger significance level (such as 0.10) and not a small significance level α (such as 0.01).
This will increase type I error but that is okay since we do not have serious consequences for it.
Answer:
2
Step-by-step explanation:
We know that P(Tail) = 1/2 and you want that to happen 4 times:
P(4Tails) = (1/2)(1/2)(1/2)(1/2)
P(4Tails) = 2
<em>You multiply because it is an </em><em>and</em><em> situation.</em>
