Answer:
Hi your question is incomplete attached below is the complete question
answer : p ( X < 725 ) = 0.0116
Step-by-step explanation:
Given data:
Average life of bulbs (μ ) = 750 hours
standard deviation (б ) = 55 hours
n ( sample size ) = 25
X = 725
<u>Probability that the mean life of a random sample of 25 bulbs will be less than725 hours </u>
p ( X < 725 ) = p (( X - μ )/ б √n < 725 - 750 / 55√25 )
= P ( Z > - 2.27 )
Hence P ( X < 725 ) = 0.0116 ( using Z-table )
I reccomend the search bar up at the top ("What is your question") before you ask questions, to make sure they're not already answered.
There is a formula d = rt, distance = rate*time. So
r = d/t.
r = 7mi/55min = 0.127mi/min
Or another way to see this:
Very technically, yes. But . . .
-- Its angles would be 0°, 0°, and 180° .
-- Its height and area would both be zero.
-- It would look like a line segment, because the two ' 6 ' legs
would have to be wide open in a straight line, and they would
lie right on top of the ' 12 ' leg ... that's the only way they could
reach between the ends of it.
