Answer:
X = 25 because 25 · 3/5, you will get 15
Well, 217 miles ÷ 62 MPH is 3.5.
so it took the train 3.5 hours.
check it: 62 MPH x 3.5 hours, it went 217 miles
Answer:michelle
Step-by-step explanation: it is 70% of the cost since it’s 30% of the original
Answer: the probability that a measurement exceeds 13 milliamperes is 0.067
Step-by-step explanation:
Suppose that the current measurements in a strip of wire are assumed to follow a normal distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = current measurements in a strip.
µ = mean current
σ = standard deviation
From the information given,
µ = 10
σ = 2
We want to find the probability that a measurement exceeds 13 milliamperes. It is expressed as
P(x > 13) = 1 - P(x ≤ 13)
For x = 13,
z = (13 - 10)/2 = 1.5
Looking at the normal distribution table, the probability corresponding to the z score is 0.933
P(x > 13) = 1 - 0.933 = 0.067
