Answer:
P(a junior or a senior)=1
Step-by-step explanation:
The formula of the probability is given by:

Where P(A) is the probability of occurring an event A, n(A) is the number of favorable outcomes and N is the total number of outcomes.
In this case, N is the total number of the students of statistics class.
N=18+10=28
The probability of the union of two mutually exclusive events is given by:

Therefore:
P(a junior or a senior) =P(a junior)+P(a senior)
Because a student is a junior or a senior, not both.
n(a junior)=18
n(a senior)=10
P(a junior)=18/28
P(a senior) = 10/28
P(a junior or a senior) = 18/28 + 10/28
Solving the sum of the fractions:
P(a junior or a senior) = 28/28 = 1
Answer:
$63.36
Step-by-step explanation:
First we need to determine how many pencils are needed
8 pencils times 96 students
8*96 =768 pencils
A dozen is 12 pencils
Divide the number of pencils needed by 12 to determine how many dozen pencils are needed
768/12 =64
We need 64 dozen pencils
They cost .99 per dozen
64*.99 =63.36
It will cost $63.36 for the pencils
Answer:
x²+2x+3....
Step-by-step explanation:
The given expression is:
5x3+10x2+15x/5x
To simplify this expression take out the common of the numerator:
5x is common in all three terms of the numerator:
Like,
5x(x²+2x+3)/5x
Now the value of the common and the denominator is same. Therefore 5x will be cancel out by 5x
Then the remaining term is:
= x²+2x+3
Thus the answer is x²+2x+3....
Subtract 6x from both sides, then square root, and have parabola.
