Answer:
Required probability is 0.9748
Step-by-step explanation:
given data
mean
= 117.7-cm
standard deviation
= 2.2-cm
sample size n = 29
solution
we consider here random variable which represents here length of rod= x
so get here first z that is express as
put here value with x value 118.5-cm

Z = 1.9582
p value is 0.9748
so required probability is 0.9748
Answer:
50%
Step-by-step explanation:
Since there is either heads or tails, meaning only two options you have a 50% chance of getting heads
A and 90-a is the measure of the two angles
a=90-a-6
2a=84
a=42
42° and 48°
A.


cost is $16.50
B.

rearrange to solve for t:

C. This is the same as part B, only the rate changed

they ask for the greatest number of minutes, so we round down (take the floor of the value).
the answer is 105 minutes.
