After moving into a new house, a couple wants to have a concrete patio poured to support a hot tub, because... well, because it's a hot tub. The plans call for a 6 ft by 17 ft slab of concrete 8 inches thick. which has a total volume of 2.52 cubic yards. The contractor estimates the amount needed at 3 cubic yards.

Find the percent error in the estimate compared to the actual amount of concrete needed.
Round to the nearest tenth of a percent.
a) The percent error in the estimate compared to the actual amount of concrete needed is __%

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
