in a certain recipe, 2 1/4 cups of flour are called for to make a cake that serves 6. of mrs. jenkins wants to use the same reci
Phoenix [80]

If in a certain recipe, a cake serving 6 persons require 2(\frac{1}{2} ) cups of flour and Mrs. Jenkins wants to use the same recipe to make a cake for 8, then she will need to use 3(\frac{1}{3}) cups of flour.


As per the question statement, 2(\frac{1}{2} ) cups of flour are required to bake a cake that serves 6. Mrs. Jenkins wants to use the same recipe to bake a cake for 8.

We have to calculate the number of cups of flours she will need to bake her desired cake as per the same recipe.

To solve this question, we will simply use the unitary method, i.e.,

A cake serving 6 required 2(\frac{1}{2} )=\frac{5}{2} cups of flour in its preparation, then,

A cake serving 1 person will require \frac{\frac{5}{2} }{6} =\frac{5}{12} cups of flour, and finally,

A cake serving 1 person will require (\frac{5}{12} *8)=\frac{10}{3}=3(\frac{1}{3}) cups of flour.

Hence, Mrs. Jenkins wants to use the same recipe to make a cake for 8, then she will need to use 3(\frac{1}{3}) cups of flour.

  • Unitary Method: In Mathematics, the unitary method is a problem-solving technique where, we first find the value of a single unit, and then calculate the necessary value by multiplying that single unit value.

The expected value of the discrete distribution is of 20.97, hence option C gives the correct answer.

<h3>What is the mean of a discrete distribution?</h3>

The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability.</u>

Hence, according to the table, the expected value is given by:

E(X) = 12 x 0.08 + 18 x 0.15 + 20 x 0.31 + 22 x 0.08 + 24 x 0.15 + 25 x 0.23 = 20.97.
