Quarts of vinegar 3: Cups of Baking soda :4 |

According to the recipe, exactly how many cups of baking soda need to be mixed with 9 1/2 quarts of white vinegar

From the above recipe

3 quarts of vinegar = 4 cups of baking soda

9 1/2 quarts of vinegar = x

Cross Multiply

3 × x = 4 × 9 1/2

3x = 4 × 19/2

x = 4 × 19/2 ÷ 3

x = 4 × 19/2 × 1/3

x = 12.666666667 cups of baking soda or 12 2/3 cups of baking soda

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
