College students average 8.6 hours of sleep per night with a standard deviation of 35 minutes. If the amount of sleep is normall
Soloha48 [4]

Answer:

4.27%

Step-by-step explanation:

We have been given that college students average 8.6 hours of sleep per night with a standard deviation of 35 minutes. We are asked to find the probability of college students that sleep for more than 9.6 hours.

We will use z-score formula to solve our given problem.

z=\frac{x-\mu}{\sigma}

z = z-score,

x = Random sample score,

\mu = Mean,

\sigma = Standard deviation.

Before substituting our given values in z-score formula, we need to convert 35 minutes to hours.

35\text{ min}=0.58\text{ Hour}

z=\frac{9.6-8.6}{0.58}

z=\frac{1}{0.58}

z=1.72

Now, we need to find P(z>1.72).

Using formula P(z>a)=1-P(z, we will get:

P(z>1.72)=1-P(z

Using normal distribution table, we will get:

P(z>1.72)=1-0.95728

P(z>1.72)=0.04272

0.04272\times 100\%=4.272\%

Therefore, 4.27% of college students sleep for more than 9.6 hours.

What is the angle of rotation of the minute hand of a clock moving from 6:10 to 7:00?
igomit [66]
Because the movement of the minute han of a clock is clockwise ↓, then the angle of rotation will be negative.

1) we calculate the number of minutes from 6:10 to 7:00

number of minutes=7:00-6:10=6:60 - 6:10=50 minutes.

2)
We know that:
60 minutes of a clock have turned -360º
Then:

60 minutes of a clock------------------------- -360º
50 minutes of a clock-------------------------      x

x=(50 minutes of a clock * (-360º))/60 minutes of a clock=-300º


Answer:  A. -300º
