Nataly_w [17]2 years ago
8 0

Answer:

16%

Step-by-step explanation:

<em><u>Find the total number of throws</u></em>

3 + 5 + 8+ 11 + 14 + 16 + 15 + 12 + 9 + 5 + 1

When you add these together, you get 100

<em><u>Find the number of 7s that were thrown</u></em>

The number of 7s thrown was 16

<em><u>Find the probability that a 7 was thrown.</u></em>

P(7) = 16/100 = 0.16

<em><u>Find the %.</u></em>

0.16 * 100 = 16%

A truck driver travels at 59 miles per hour. The truck tires have a diameter of 30 inches. What is the angular velocity of the w
Misha Larkins [42]

Answer:

661.4\ rpm

Step-by-step explanation:

we know that

1 mile=63,360 inches

step 1

Find the circumference of the wheels

C=2\pi r

we have

r=30/2=15\ in -----> the radius is half the diameter

substitute

C=2\pi(15)

C=30\pi\ in

assume

\pi =3.14

C=30(3.14)=94.2\ in

Remember that    

The circumference of the wheels represent one revolution

Convert 59 miles per hour to inches per minute

59\ mi/h=59*63,360/60=62,304\ in/min

using proportion find the number of revolutions  

\frac{1}{94.2}\frac{rev}{in}=\frac{x}{62,304}\frac{rev}{in}\\ \\x=62,304/94.2\\ \\x=661.4\ rev

therefore

substitute

62,304\ in/min=661.4\ rev/min=661.4\ rpm
