Answer:
17 wins
Step-by-step explanation:
Given
P(winning) = 1/5
Number of games = 85
The number of winnings could simply be calculated as the product of the probability and number of games played.
Expected number of winning : P(winning) * number of games
Expected number of winning = 1/5 * 85 = 17 wins
Answer:
Step-by-step explanation:240 : 24=10
Hourly rate is $10.00
Answer:
V = 8491 mm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius is 13 and the height is 16
V = pi * (13)^2 *16
V = 169*16 *pi
V =2704 *pi
Let pi be approximated by 3.14
V =2704(3.14)
V =8490.56
To the nearest whole number
V = 8491 mm^3
The correct question is:
What is the probability that 2 girls and 2 boys will be selected?
Solution:
Total number of students = 10
Ways to select a team of 4 students = 10C4 = 210
2 Boys can be selected from 6 boys in ways = 6C2 = 15
2 Girls can be selected from 4 girls in ways = 4C2 = 6
Number of ways to select 2 boys and 2 girls = 15 x 6 = 90
Probability of choosing 2 boys and 2 girls = 90/210 = 3/7
Thus, if 4 team members are selected, the probability of choosing 2 boys and 2 girls will be 3/7
First, we find the area of the circle.
A = pi * r^2
A = pi * (1 cm)^2
A = pi cm^2
The area of the circle is pi cm^2.
The area of the triangle is also pi cm^2.
Now we use the area of a triangle.
A = (1/2)bh
(1/2)bh = A
(1/2)(3 cm)h = pi cm^2
(3 cm)h = 2pi cm^2
h = (2/3)pi cm
The exact height is 
If you want an approximate height, then it is 2.09 cm.
