What is the value of x?

Mathematics
1 answer:
fredd [130]3 years ago
3 0

Answer: 4

Step-by-step explanation:

Well, first you need to use the 30-60-90 special triangle property to find out the length of the hypotenuse triangle with the side with the length 2√3.

The 30-60-90 property states that if the hypotenuse is x, then the leg opposite to 30 degrees has the length of x/2 and the leg opposite to 60 degrees has the length of (x√3)/2. So if the leg opposite to 60 degrees has a length of 2√3, the hypotenuse can be found with this equation: 2√3=(x√3)/2, and when you solve this equation, you should get x=4.

Now that you have figured out the hyptenuse of the 30-60-90 triangle, you can use that leg to find the length of the other leg in the 45-45-90 triangle. Since both of the legs are opposite to the same degree angle, they are both congruent, and the value of x in the problem is 4.

What is the ninth term in A(n)=-4 - 6(n-1)?
Ghella [55]

Answer:

A(9) = -52

Step-by-step explanation:

The given sequence is :

A(n)=-4 -6(n-1)

We need to find the 9th term of the above sequence.

To find it, put n = 9 in the above sequence.

A(9) = -4 -6(9-1)

= -4-6(8)

= -4-48

= -52

Hence, the 9th term of the sequence is -52.

For each of the following​ situations, indicate what the general impact on the Type II error probability will​ be:
Paraphin [41]

Answer:

Step-by-step explanation:

Hello!

The type II error is committed when you fail to reject a false null hypothesis.

The probability associated with this type of error is symbolized as β.

a. The alpha level is increased.

α and β are two probabilities that are closely related in such a way that if alpha is decreased, beta automatically increases and vice versa when the sample size n is predetermined.

If you increase α then the probability of committing type II error (β) decreases.

b. The "true" population mean is moved farther from the hypothesized population mean.

If the true population mean is moved away from its hypothesized value, then the probabilities of "keeping" a false null hypothesis are bigger.

c. The alpha level is decreased.

This is the inverse situation from a. If you decrease α then, β is automatically increased.

d. The sample size is increased.

If the sample size "n" is left free, it can be shown that by increasing the sample size, both α and β decrease. In practice, α is fixed and β is calculated with several possible sizes of n. Finally choosing as sample size the one that minimizes or gives a reasonable value of β.

I hope it helps!
