In tests of a computer component, it is found that the mean time between failures is hours. A modification is made which is supposed to increase reliability by increasing the time between failures. Tests on a sample of modified components produce a mean time between failures of hours. Using a level of significance, perform a hypothesis test to determine whether the mean time between failures for the modified components is greater than hours. Assume that the population standard deviation is hours.

factor trees are nice.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

yes, i heard the "tea" with james charles and a few other beauty gurus. i believe charles is in the wrong and i believe tati the most. tati didn't lie about james charles but may have exaggerated because he never sexually assaulted anyone. jeffery star is a really good friend to all and out anyone that needs it, until you mess with one of his "sisters"! james will never rise over jeffery or tati, he's way to sensitive and dramatic to rise about them. i think all three of them will make up and be friends again because they always get over it.

i hope this with your
