In this question, we're trying to find how many hours Mike had the bike for.
We know that 13 dollars as a flat rate.
We also know that they charge 13 dollars and hour.
Mike paid a total of 67 dollars for the bike.
Lets represent this as an equation:
67 = 9x + 13
x = hours the bike was rented
Solve for x:
67 = 9x + 13
Subtract 13 from both sides
54 = 9x
Divide both sides by 9
6 = x
This means that Mike rented the bike for 6 hours.
Answer:
6 hours
Answer:
Probability that next week's show will have between 30 and 37 million viewers is 0.2248.
Step-by-step explanation:
We are given that the distribution of the number of viewers for the American Idol television show follows a normal distribution with a mean of 26 million with a standard deviation of 8 million.
<em>Let X = number of viewers for the American Idol television show</em>
So, X ~ N(
)
Now, the z score probability distribution is given by;
Z =
~ N(0,1)
where,
= population mean = 26 million
= standard deviation = 8 million
So, probability that next week's show will have between 30 and 37 million viewers is given by = P(30 < X < 37) = P(X < 37) - P(X
30)
P(X < 37) = P(
<
) = P(Z < 1.38) = 0.91621
P(X
30) = P(
) = P(Z
0.50) = 0.69146
<em>Therefore, P(30 < X < 37) = 0.91621 - 0.69146 = 0.2248</em>
Hence, probability that next week's show will have between 30 and 37 million viewers is 0.2248.
