A recipe for 10 servings of raspberry sorbet calls for 2 cups of water, 1ż cups of granulated sugar, and 4 cups of
ehidna [41]

Answer:

\huge\boxed{\sf 320\ servings = 4\ gallons}

Step-by-step explanation:

1 gallon = 16 cups (STANDARD)

For 10 servings:

10 servings = 2 cups of water

10 servings = 2 / 16 gallons

10 servings = 0.125 gallons

<u>For 320 servings:</u>

10 servings = 0.125 gallons

Multiply both sides by 32

10 * 32 servings = 0.125 * 32 gallons

320 servings = 4 gallons

\rule[225]{225}{2}

Hope this helped!

Rama09 [41]
To answer this item, find first the z-score of the given data.

    z-score = (x - m) / d

where x is data point, m is the mean and d is the standard deviation

Substituting the given values,

    z-score = (188 - 176.7) / 9.9  = 1.14

This translates to a percentage of 87.29%. 

Because we are asked of the percentage of those with height greater than this, that would be,
     100 - 87.29% = 12.71%

Answer: 12.71%

Two-thirds of students in a class are girls. If one-half of the girls wear glasses, what fractional part of students are girls w
Fantom [35]

Let's assume the number of students in the class be x.

Given that, Two-thirds of students in a class are girls.

So, number of girls =\frac{2}{3} x

Now ne-half of the girls wear glasses. So, one-half of \frac{2}{3} x is

= \frac{1}{2} *\frac{2}{3} x

=\frac{1}{3} x Cancel out 2 from both numerator and denominator.

So, one third of the students are girls who wear glasses.

So, the correct choice is E.
