Answer:
The probability that all are male of choosing '3' students
P(E) = 0.067 = 6.71%
Step-by-step explanation:
Let 'M' be the event of selecting males n(M) = 12
Number of ways of choosing 3 students From all males and females

Number of ways of choosing 3 students From all males

The probability that all are male of choosing '3' students


P(E) = 0.067 = 6.71%
<u><em>Final answer</em></u>:-
The probability that all are male of choosing '3' students
P(E) = 0.067 = 6.71%
Answer:
a = 38⁰
b = 54⁰
c = 54⁰
Step-by-step explanation:
a + 142⁰ = 180⁰ because a straight line = 180⁰
b + 38⁰ + 88⁰ = 180⁰ because the angles of a triangle equal 180⁰, and the missing measurement = 38⁰ because it is a vertical angle to angle a
c + 88⁰ = 142⁰ because the angles are corresponding angles
The volume of a sphere is 
So, if the small sphere has radius
and the largest sphere has radius
, their volumes are

So, their ratio is

Answer:
0.025
Step-by-step explanation:
The equation 13x+30=134 can be used to find the number of months Kenneth can receive internet service.
Step-by-step explanation:
Given,
Start up fee to receive internet = $30
Per month charges = $13
Total amount = $134
Let,
x be the number of months.
y be the total cost.
y = 13x+30
Putting y=134

The equation 13x+30=134 can be used to find the number of months Kenneth can receive internet service.
