Answer:
0.85
Explanation:
Using the addition law of probability which states that for two events A and B, the probability that A or B will occur is the sum of their individual probabilities minus the probability that both A and B will occur. The addition rule is given by the formula:
P(A or B) = P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
Let probability that a college freshman takes a math class the first semester = P(A) = 0.75
probability that a college freshman takes an English class the first semester = P(B) = 0.70
probability that a college freshman takes both a math class and an English class the first semester = P(A ∩ B) = 0.60
the probability that a college freshman takes a math class or an English class the first semester = P(A ∪ B) = P(A or B)
Therefore, P(A or B) = P(A ∪ B) = P(A) + P(B) - P(A ∩ B) = 0.75 + 0.7 - 0.6 = 0.85
P(A or B) = 0.85
Read the excerpt below from Raise Happy Chickens and Other Poultry and answer the question that follows.
Once you have decided that keeping chickens is feasible, which breed will suit you? If you sort out your priorities, you will find this out. You need to decide whether you want lots of eggs per week or only a few; meat; beauty; rare breeds; pets; your vegetable garden weeded. No single type or breed will fulfill all of these requirements and it is so important that you like the look of the hens you buy as they will become part of the family.

Read the following paragraph that Elijah wrote about Lawton Allen, founder and president of Hope House, for his blog series “Inspirational Stories”: More than 50 people have found jobs through this program. Mr. Allen was once homeless. You can take a career class there and get help with a job search. Hope House was founded in March 2014. Did you know that they will fit you for a suit so you can go to a job interview? The organization has nonprofit status, so most of the budget can be spent helping people. Hope House is a place to go when you are down on your luck. How could Elijah improve his writing?
Answer:
Elijah has too many ideas in his paragraph. With this single jam-packed paragraph, he’s provided too many details and no real focus. Elijah needs to decide what his most important idea is and place it prominently in his first paragraph. Then he should move the other ideas to the following paragraphs and provide details to support them.

The equation y = - 8) is graphed in the zy-plane. Which of the following equations will
have a graph that is parallel to the graph of the above equation and have an X-intercept on the
negative x-axis?
Answer:
[tex]y = \frac{3}{2}(x + 8)[/tex]
Explanation:
Given
[tex]y = \frac{3}{2}(x - 8)[/tex]
Required
Equation of line with the same slope and x intercept on negative axis
We start by solving for the slope of the first equation.
It should be noted that the slope of a line (in equation form) is the coefficient of x.
So, we start by opening the bracket of [tex]y = \frac{3}{2}(x - 8)[/tex]
This gives
[tex]y = \frac{3}{2}(x) - \frac{3}{2}(8)[/tex]
[tex]y = \frac{3}{2}(x) - \frac{24}{2}[/tex]
[tex]y = \frac{3}{2}(x) - 12[/tex]
Hence, the slope of the line is [tex]\frac{3}{2}[/tex]
To solve for x intercept, we simply substitute 0 for y. This gives.
[tex]0 = \frac{3}{2}(x) - 12[/tex]
Add 12 to both sides
[tex]12 + 0 = \frac{3}{2}(x) - 12 + 12[/tex]
[tex]12 = \frac{3}{2}(x)[/tex]
Multiply both sides by ⅔
[tex]\frac{2}{3} * 12 = \frac{3}{2}(x) * \frac{2}{3}[/tex]
[tex]\frac{24}{3} = \frac{3}{2}(x) * \frac{2}{3}[/tex]
[tex]\frac{24}{3} = x[/tex]
[tex]8 = x[/tex]
[tex]x = 8[/tex]
This is the x intercept of equation [tex]y = \frac{3}{2}(x - 8)[/tex]
From the question we understand that the second equation has the same slope and has a negative x intercept as [tex]y = \frac{3}{2}(x - 8)[/tex]
For two parallel lines, their slope are always equal.
Hence, the second equation has the following info.
[tex]Slope = \frac{3}{2}[/tex]
[tex]x,intercept = -8[/tex]
This can be rewritten as follows;.
x = -8
Add 8 to both sides
x + 8 = -8 + 8
x + 8 = 0
Multiply both sides by the slope (3/2)
[tex]\frac{3}{2}(x + 8) = \frac{3}{2} * 0[/tex]
[tex]\frac{3}{2}(x + 8) = 0[/tex]
Recall that to solve for x intercept, we simply substitute 0 for y.
At this point, we also replace 0 with y.
This gives
[tex]\frac{3}{2}(x + 8) = y[/tex]
[tex]y = \frac{3}{2}(x + 8)[/tex]
Hence, the equation of the second line is [tex]y = \frac{3}{2}(x + 8)[/tex]

Listen to the other person not me!
Explanation:
someone help me please!
Answer:
1) 28.6%
2) 78.6 %
3)
(a) 75%
(b) 25%
Explanation:
1)
14 total blocks.
4 red blocks
Probability that the block is red:
[tex]\frac{4}{14}[/tex] = 0.286 = 28.6%
2)
There are 3 yellow blocks.
14 total blocks - 3 yellow blocks = 11 blocks that are not yellow
Probability that the block is not yellow:
[tex]\frac{11}{14}[/tex] = 0.786 = 78.6%
3)
(a)
The word or means that you need to add the probabilities together.
63 + 12 = 75%
(b)
Probability that Joe Starr will sign with the Yankees or the Dodgers is 75%.
If Joe Starr signs with a team other than the Yankees or the Dodgers, you need to subtract 75 from 100
100 - 75 = 25%
Most college campuses offer a _____________

A. recreation center
B. club membership
C. yoga and Pilates studio
D. gym membership
Most college campuses offer a recreation center for students to exercise.
What is Recreation center?
The activities of everyday living, employment, sleep, social responsibilities, and leisure take up much of a person's time.
Recreation requires time that is free from prior obligations to physiologic or social demands. In spite of the fact that leisure time has expanded along with lifespan and, for many, with fewer hours needed for physical and financial survival, some contend that time pressure has increased for modern individuals as a result of their commitment to too many responsibilities.
Affluence, demographic patterns, and growing commercialization of recreational options are further factors contributing to an enhanced role for recreation.
Therefore, Most college campuses offer a recreation center for students to exercise.
