2,345 is 7% of 33,500 There are many sites that can show you how to get a percentage so I am going to move onward. You will add the seven percent on each year, like the following

First Year: 33,500
Second Year: 35,845 (+7%=2,345)
Third Year:38,354.15 (+7%=2509.15)

If h and j are positive, (h+j)2 = 73 and h2 +j2 = 51, what is hj?

kkurt [141]

Answer:

$hj = 11$

Step-by-step explanation:

$(h+j)^2=73,\:\: and\:\: h^2+j^2 =51$ (Given)

$(h+j)^2 = h^2+j^2 +2hj$

$\implies 73= 51 +2hj$

$\implies 73- 51 =2hj$

$\implies 22 =2hj$

$\implies hj = \frac{22}{2}$

$\implies hj = 11$

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:

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

Vlada [557]

Answer:

$x=15$

Step-by-step explanation:

We are given the equations $2(x+9), 30+18$ to search for a value of $x$ that yields an equivalent statement. $2(x+9)=30+18\\2(x+9)=48\\x+9=24\\x=15$ .
