Answer:
0.34134
Step-by-step explanation:
in other to solve for this question we would be using the z score formula
z = (x - μ) / σ
x = raw score
μ = mean
σ = standard deviation
the question tells us to find the probability that a worker selected at random makes between $350 and $400
let x1 = 350 and x2= 400 with the mean μ = 400 and standard deviation σ = $50.
z1 = (x1 - μ) / σ = (350-400) / 50 = -1
z2 = (x2 - μ) / σ = (400 - 400) / 50 = (0/50) = 0
from tables, P(z <= -1) = 0.15866
P(z <= 0) = 0.5
then the probability would give us, P(-1 ≤ z ≤ 0) =0.5 - 0.15866 =
0.34134
that explains that the probability that a worker selected at random makes between $350 and $400 = 0.34134
Probability to get an bad battery
=10/25
=2/5
Probability that all 4 are bad
=2/5×2/5×2/5×2/5
=16/625
Answer:
The correct option is 2. The best estimate for the price of the house in year 2018 is $407,000.
Step-by-step explanation:
The given equation is
Where p is the average sale price of house (in thousands of dollars) and t is number of years since 2010.
We have to find the best estimate for the price of the house in year 2018. The difference between 2018 and 2010 is 8 years.
Substitute t=8.
Therefore the estimate for the price of the house in year 2018 is 407 thousand dollars, i.e.,$407,000. Option 2 is correct.
