Probability helps us to know the chances of an event occurring. The probability that a randomly selected student is a junior is 0.35.
<h3>What is Probability?</h3>Probability helps us to know the chances of an event occurring.
The probability that a randomly selected student is a junior will be,
P(Junior) = [(Number of Juniors)\(Number of total students)]
P(Junior) = 35/100 = 0.35
Hence, The probability that a randomly selected student is a junior is 0.35.

Answer:
1) (2x - 3)(x + 5)
2) 1.5, -5
3) Open upwards from both ends
4) Minimum
Step-by-step explanation:
Step 1:
The given polynomial is:
Taking out commons, we get:
This is the factorized form of the polynomial.
Step 2:
The zeros of the functions occur when the function is equal to zero.
i.e.
This means, the zeros of the polynomial are 1.5 and -5
Step 3:
The end behavior of a graph depends on its degree and the sign of leading coefficient. Since the degree is even and the coefficient is positive the graph of the polynomial will opens upwards from left and right side.
Step 4:
The given polynomial is a quadratic function with positive leading coefficient. Since it open vertically upwards, its vertex will be the lowest most point. So, the vertex will be the minimum of the function.
Answer:
the number of children has red or brown hair is .
Step-by-step explanation:
We have been given that in Marci's family there are total 6 children.
Out of 6 children
Number of children have blonde hair =
Number of children have red hair =
Number of children have brown hair =
Since, we have to find the fraction of children has red or brown hair=
Hence, the number of children has red or brown hair is
The value of x is 9 and AD is 54.
<u>Step-by-step explanation:</u>
From figure, if DC = AD, we can solve for value 'x'
DC = AD
Given:
DC = 6 x
DA = 4 x + 18
Equating the values of both, we get
6 x = 4 x + 18
6 x - 4 x = 18
2 x = 18
x = 9
So, the value of x is 9. By using this value of x, find AD
AD = 4 (9) + 18
AD = 36 + 18
AD = 54
