Answer:

Probability of event E = (4/10) = 0.40

Step-by-step explanation:

Note that n(E) is the number of outcomes in E

n(S) is the number of outcomes in S

And with each outcome having equal likelihood of occurring,

SetS = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.

n(S) = 10

Event E = {1, 4, 7, 9}.

n(E) = 4

Probability of event E = n(E)/n(S)

Probability of event E = (4/10) = 0.40

Hope this Helps!!

A skydiver is falling at approximately 28 feet per second. Find the skydiver's change in altitude
Free_Kalibri [48]

9514 1404 393

Answer:

  -140 feet

Step-by-step explanation:

The relation between speed, distance, and time can be written ...

  distance = speed × time

  distance = (28 ft/s)(5 s) = 140 ft

In 28 seconds, the skydiver changed position by 140 feet. Since the direction is presumed to be down (falling), the change in altitude is -140 feet.

The ratio of boys to girls in a group is 7:1. If there are 66 more boys than girls, work out how many girls there are
nevsk [136]

Answer:11

Step-by-step explanation:

Boys : girls=7:1

Sum of ratio=7+1=8

Let them number of girls be y

Then they number of boys=y+66

Total number of pupils=y+y+66

Total number of pupils=2y+66

Number of girls=(girls ratio)/(sum of ratio) x (total number of pupils)

y=1/8 x (2y+66)

Cross multiply

y x 8=2y + 66

8y=2y + 66

Collect like terms

8y-2y=66

6y=66

Divide both sides by 6

6y/6=66/6

y=11

The number of girls is 11

A packing carton in the shape of a triangular right prism shown below. Find the volume of the prism.
Annette [7]

Answer: The volume is 120 in^3.

Step-by-step explanation:

-The volume formula for a triangular prism is:

(Height × Base × Length) /2

-So, you put the height, base, and length:

(4 × 6 × 10)

-Then, you solve:

(4 × 6 × 10)

(24 × 10)

240

-Divide 240 by 2:

240 ÷ 2

120

Therefore, the volume of a Triangular Prism is 120in^3.
