Two suppliers manufacture a plastic gear used in a laser printer. The impact strength of these gears measured in foot-pounds is an important characteristic. A random sample of 10 gears from supplier 1 results in and and another random sample of 16 gears from the second supplier results in and Is there sufficient evidence to conclude that the variance of impact strength is different for the two suppliers? Use Round numeric answer to 2 decimal places. Since the test statistic, f0 = Enter your answer; Since the test statistic, f0 = ,Choose your answer; _ in the rejection region in the rejection region, there Choose your answer; there _ sufficient evidence to conclude that the variance of impact strength is different for the two suppliers sufficient evidence to conclude that the variance of impact strength is different for the two suppliers.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.

step-by-step explanation:

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
