Answer:

The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9

Step-by-step explanation:

Fraction of Portion

Suppose we have a number n and another number m such as m>n. The portion or fraction of size n of m is given by the quotient n/m.

For example, 3 pieces of cake out of a total of 6 make them a fraction of 3/6 = 1/2 of the whole cake, i.e. half of the total available.

Mrs. Manning needs 1/3 cup of flour to make cookies for the bake sale. She actually has 3/4 cups of flour. Calculate the fraction of needed against the available flour:

$\displaystyle \frac{\frac{1}{3}}{\frac{3}{4}}$

The division can be easier performed by multiplying by the reciprocal of the denominator:

$\displaystyle \frac{1}{3}\cdot \frac{4}{3}=\frac{1*4}{3*3}$

$\displaystyle =\frac{4}{9}$

The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9

Step-by-step explaanation:

We are regarding a normal distribution with a mean of 35 and a standard deviation of 6, i.e., $\mu$ = 35 and $\sigma$ = 6. We know that the probability density function for a normal distribution with a mean of $\mu$ and a standard deviation of $\sigma$ is given by
