Students randomly receive 1 of 4 versions (A, B, C, D) of a math test. what is the probability that at least 3 of the 5 students tested will get version A of the test? Express your answer as a percent, and round it to the nearest tenth. Show your work, or there will be no credits. A. 8.8% B. 1.6% C. 10.64% D. 74.7%

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

step-by-step explanation:

what was your answer?

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
