The proper air pressure for Caitlin's bicycle tire is 30 lbs per square inch (psi). The percent error in Caitlin's current tire pressure is 15%. What is the amount of error?(Use percent error formula) a. 300 psi b. 1.5 psi c. 4.5 psi d. .15 psi the proper air pressure for Caitlin's bicycle tire is 30lbs per square inch. The percent error in Caitlin's current tire pressure is 15%. Using the amount of error found in the last question what are the possible tire pressures a. 29.85-30.15psi b. 25.5-34.5psi c. 28.5-31.5psi d. 270-330psi​

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

i think 1: 2

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
