Aquality control expert at life batteries wants to test their new batteries. the design engineer claims they have a variance of 5929 with a mean life of 941 minutes. if the claim is true, in a sample of 109 batteries, what is the probability that the mean battery life would be greater than 948.8 minutes? round your answer to four decimal places.

ik how do do this just give me a few minutes and i will give it to

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
