Look at the figure. Which trigonometric ratio should you use to find x?
Elis [28]

Answer:

B.  Sine.

Step-by-step explanation:

We need to find the value of x which is opposite to the given angle  (50 degree).  Also we are given the length of the hypotenuse.

Sine = opposite / hypotenuse so we would use the sine.

Its worth committing this mnemonic to memory, which helps to find the required trig ratio:

SOH-CAH-TOA.

SineOpposite/Hypotenuse- CosineAdjacent/Hypotenuse-TangentOpposite/Adjacent.

Suppose a random sample of n measurements is selected from a binomial population with probability of success p = .39. Given n =
Oksi-84 [34.3K]

Answer:

The answer is below

Step-by-step explanation:

a) Given that the number of sample (n) = 300, therefore since n > 30, the distribution of the sample means is going to be normally distributed.

b) The mean of the distribution of sample means (also known as the Expected value of M) is equal to the population mean μ.

\mu_x=\mu=np=300*0.39=117

c) The standard deviation of the distribution of sample means is called the Standard Error of M, it is given by:

\sigma_x=\sqrt{np(1-p)} =\sqrt{300*0.39(1-0.39)} =8.44

inessss [21]

Answer:

Total number of copies sold till date are 381522.

Step-by-step explanation:

It is given in the question the book sold 35100 copies in its first month of release and this number is 9.2% of the number of copies sold till date.

To find is how many copies have been sold.

Let the total number of copies sold be = A

Therefore 9.2% × A = 35100

\frac{9.2}{100}A=35100

A=\frac{35100\times 100}{9.2}

A = 381521.74 ≅381522 copies
