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

12 2/3 cups of baking soda

Step-by-step explanation:

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

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
