Answer:

Step-by-step explanation:

When we find the prime factorization of a number, we are essentially finding breaking it down the most we can. When we multiply the prime factors, we will get the original number that we broke down.

So, let's multiply the prime factors

2*4*5 = 40

If we wanted to check, we can do so by finding the prime factors of 40.

Btw, 4 is not a prime number. We would factor 4 into 2 × 2. Then we would have 2³, as there are three 2s. The correct way to write this prime factorization would be,

2³ × 5

suppose that incomes of families in Newport Harbor are normally distributed with a mean of $750,000 and a standard deviation of

denis23 [38]

Answer: 0.345

Step-by-step explanation:

Given : The incomes of families in Newport Harbor are normally distributed with Mean : $\mu=\$ 750,000$ and Standard deviation : $\sigma= $250,000$

Samples size : n=4

Let x be the random variable that represents the incomes of families in Newport Harbor.

The z-statistic :-

$z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For x= $800,000

$z=\dfrac{800000-750000}{\dfrac{250000}{\sqrt{4}}}=0.4$

By using the standard normal distribution table , we have

The probability that the average income of these 4 families exceeds $800,000 :-

$P(x>80,000)=P(z>0.4)=1-P(z\leq0.4)\\\\=1-0.6554217=0.3445783\approx0.345$

Hence, the probability that the average income of these 4 families exceeds $800,000 =0.345
