The table shows the heights that four people parachute from an airplane. What is the range of the heights? Write your answer as a decimal or fraction in simplest form.

The answer is 1.55

Explanation:

The he first step to find the range is to make all the values either fractions or decimal/integer numbers. Below I show the process to make all the numbers decimals/integers

Height in miles

2.75: This number is decimal because of this it does not have to be modified

: This number includes a rational number and a fraction to make this just one number write the first number as a fraction, multiply, and then divide the top number by the low number (denominator).

× =

: This number is a fraction to simplify it divide the nominator by the denominator:

: Write the integer as a fraction and then simplify

×

Now, from these values, the higher one is 2.75 and the lowest is 1.2, to find the range find the difference between these two numbers 2.75 - 1.2 = 1.55

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
