A breakfast cereal producer makes its most popular product by combining just raisins and flakes in each box of cereal. The amoun
yarga [219]

Using the normal distribution, it is found that there is a 0.9192 = 91.92% probability that the total amount of product is less than 575 g.

In a normal distribution with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

  • It measures how many standard deviations the measure is from the mean.  
  • After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
  • When two normal variables are added, the mean is the sum of the means while the standard deviation is the square root of the sum of the variances.

In this problem, the product is composed by flakes and raisins, and we have that:

\mu_F = 370, \sigma_F = 24, \mu_R = 170, \sigma_R = 7

Hence, the distribution for the total amount of product has <u>mean and standard deviation</u> given by:

\mu = \mu_F + \mu_R = 370 + 170 = 540

\sigma = \sqrt{\sigma_F^2 + \sigma_R^2} = \sqrt{24^2 + 7^2} = 25

The probability that the total amount of product is less than 575 g is the <u>p-value of Z when X = 575</u>, hence:

Z = \frac{X - \mu}{\sigma}

Z = \frac{575 - 540}{25}

Z = 1.4

Z = 1.4 has a p-value of 0.9192.

0.9192 = 91.92% probability that the total amount of product is less than 575 g.

A real estate agent received 1.5% commission for a house that sold for $250,000. How much was the agent's commission?
vampirchik [111]

Answer:

The answer is B.

Step-by-step explanation:

The answer would be B because dividing 250,000 would get you 25,000 which would be 10% of the total cost. Dividing by 10 again would get you 2500 which would be 1% of the total cost. Divide 2500 by 2 and you'll get 1250. 1250 + 2500 would be 1.5% of the total cost.

F(n) = -11 + 22(n = 1)<br> Complete the recursive formula of f(n).<br> f(1) =<br> f(n) = f(n - 1)+
Maslowich

Answer:

f(n)=f(n-1)+22.

Step-by-step explanation:

Note: In the given function it should be (n-1) instead of (n=1).

Consider the given function is

f(n)=-11+22(n-1)

It is the explicit form of an A.P.

For n=1,

f(1)=-11+22(1-1)=-11+0=-11

For n=2,

f(2)=-11+22(2-1)=-11+22=11

Common difference is  

d=a_2-a_1=11-(-11)=11+11=22

The recursive formula of an A.P. is

f(n)=f(n-1)+d

Substitute d=22 in the above formula.

f(n)=f(n-1)+(22)

f(n)=f(n-1)+22

Therefore, required recursive formula is f(n)=f(n-1)+22.
