Answer:
Step-by-step explanation:
Since the number of points per game for a certain basketball player is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = number of points per game
µ = mean
σ = standard deviation
From the information given,
µ = 14 points
σ = 2 points
The probability that in a randomly selected game, the player scored more than 8 points is expressed as
P(x > 8) = 1 - P(x ≤ 8
For x = 8,
z = (8 - 14)/2 = - 3
Looking at the normal distribution table, the probability corresponding to the z score is 0.00135
P(x > 8) = 1 - 0.00135 = 0.9987
Converting to percentage, it becomes
0.9987 × 100 = 99.87%
Answer:
<u>I will take around 1 year and 8 months to earn $ 45 of interest on this investment</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Interest earned = $ 45
Investment = $ 790
Annual simple interest rate = 3.4% = 0.034
2. How much time would it take to earn $45?
Let's recall the formula for calculating the simple interest of an investment:
A = P * (1 + rt)
Replacing with the values we already have:
835 = 790 + (1 + 0.034t).
Where t is the time we want to calculate
835 = 790 + 26.86t
26.86t = 835 - 790
26.86t = 45
t = 1.68 (Rounding to the next hundredth)
<u>t ≅ 1 year and 8 months</u>
Answer: It is D.
Step-by-step explanation: I have taken this quiz before!
Please give me brianliest
A= 7843/324b. i think it might be that, not so sure
