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.

Molodets [167]
The triangle on the left appears to be congruent with the triangle on the right.  If this observation is actually valid, then x+7 = 2x-5.  12=x  Yes, I realize that this doesn't match any of the answer choices, 'tho the 4th choice is the only one that contains "12."  Would you please share the instructions for this problem.

During the 2005-2006 term. 184 decisions were announced. This is a 44.6% decrease
Artyom0805 [142]

Answer:

332.

Step-by-step explanation:

Let the number of decisions made in 1982-1983 be x.

44.6% = 0.446.

This is a decrease,  so the number of decisions announced in 2005-2006 is

(1 - 0.446) * x and this =  184.

0.554x = 184

x = 184/0.554

x = 332.
