-4x+5
Step-by-step explanation:
use FOIL
<u>Importance of origin:</u>
The point at which the two axes intersect is called the origin. The intersecting x- and y-axes divide the coordinate plane into four sections.
The origin is at 0 on the x-axis and 0 on the y-axis. Since the origin has an x-coordinate of 0 and a y-coordinate of 0, its ordered pair is written (0, 0).
The origin is used to determine the coordinates for every other point on the graph. It is generally the starting point on a grid.
In general, origin is the place where something comes from or the place where something originates.

Answer:
c. y = (x +2)² -5
Step-by-step explanation:
If you replace the squared term with zero, you are choosing the minimum of the remaining values. (A squared term cannot have a negative value.)

Answer:
D. 2.2m + 4.5
Step-by-step explanation:
Answer:
The probability that at least one of the 20 4th graders is addicted to comic books is 0.12.
Step-by-step explanation:
Let X = number of hours a 4th grader reads comics and Y = number of 4th grader addicted to reading comics.
The random variable X is continuous and follows a normal distribution with mean, μ = 6 hours and standard deviation, σ = 2 hours.
And the random variable Y is discrete and follows a binomial distribution with success defined as a 4th grader is addicted to reading comics.
Compute the probability that a 4th grader is addicted to reading comics as follows, i.e. determine the value of P (X > 11) .

Use the <em>Z</em>-table for the probability value.
Now compute the probability that out of 20 fourth graders at least 1 is addicted to comics as follows:
The Binomial probability function is:

Compute the value of
as follows:

Thus, the probability that at least one of the 20 4th graders is addicted to comic books is 0.12.
