The data below gives the mass in grams of a cube of dry ice subliminating over a period of minutes.

min: 5,18,27,33,45,50,59,65,75
grams: 320,112,98,63,40,38,24,14,2

perform an experimental regression and give the values of y=a•b^x

use the equation to estimate the number of grams remaining after 10 minutes

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
