Answer:
1%
Step-by-step explanation:
S.P of each radio=$ 2288
Total S.P=
$4576
Gain=10%
Lose=10%
C.P=
C.P=
By using the formula
C.P of one radio=
$2080
C.P of another radio=
=$2542.2
Total C.P of two radios=2080+2542.2=$4622.2
Total C.P >Total S.P
Loss=S.P-C.P
Loss=4622.2-4576=$46.2
Loss%=
Loss %=
1%
Hence, his loss 1%
Answer:
Option C
Step-by-step explanation:
Option c is right answer
Answer: the probability that a randomly selected tire will have a life of exactly 47,500 miles is 0.067
Step-by-step explanation:
Since the life expectancy of a particular brand of tire is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = life expectancy of the brand of tire in miles.
µ = mean
σ = standard deviation
From the information given,
µ = 40000 miles
σ = 5000 miles
The probability that a randomly selected tire will have a life of exactly 47,500 miles
P(x = 47500)
For x = 47500,
z = (40000 - 47500)/5000 = - 1.5
Looking at the normal distribution table, the probability corresponding to the z score is 0.067
They are most likely 90 degrees, due to the sharing of a common side and a common vertex. They really could be anything though. If given more details, I will give a better answer. I still would like Brainliest, however.
