In a bumper test, three types of autos were deliberately crashed into a barrier at 5 mph, and the resulting damage (in dollars) was estimated. five test vehicles of each type were crashed, with the results shown below. research question: are the mean crash damages the same for these three vehicles? goliath varmint weasel 1600 1290 1090 760 1400 2100 880 1390 1830 1950 1850 1250 1220 950 1920

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.

step-by-step explanation:

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
