Hi this was my last test, the answers complementary
Answer:
a. A quadratic can only have one y-intercept.
Step-by-step explanation:
We have to simplify the given expression:

Dividing the terms of the numerator by the given term of denominator individually, we get
= 
By using the laws of exponent,
, we get
= 
= 
= 
= 
Therefore, the simplification of the given expression is
.
So, Option 3 is the correct answer.
Given:
Point k is located on the y-axis 8 units away from the origin.
To find:
The coordinates of point k.
Solution:
Since point k is located on the y-axis, therefore it means the x-coordinate is 0.
Point k is 8 units away from the origin. So, it can be either or positive or negative side of y-axis.
If k is on the negative side of y-axis then y-coordinate of point k is -8.
If k is on the positive side of y-axis then y-coordinate of point k is 8.
Therefore, the possible coordinates of point k are either (0,-8) or (0,8).
Answer:
P(X = 3) = 0.1442
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
In this problem we have that:

We have to find P(X = 3).
