The probability that a college freshman takes a math class the first semester is 0.75. The
probability that a college freshman takes an English class the first semester is 0.70. The
probability that a college freshman takes both a math class and an English class the first
semester is 0.60. Find the probability that a college freshman takes a math class or an English
class the first semester.
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

18. In poultry, feathered shank (F) is dominant over clean shank (f). If the
hen's genotype is represented by ff and the rooster's genotype is Ff, what
percentage of their offspring would be expected to have feathered
shanks?
0%
50%
75%
100%
Answer:
50%
Explanation:
f f
F Ff Ff
f ff ff
There are two Ff and two ff
Thus, the percentage of their offspring that would be expected to have feather shanks is [tex]\frac{2}{4}[/tex] [tex]\times[/tex] 100 = 50%
+23PTS! PDF Volume question -_- find diameter from the cylinder. I got 9 answer is 6 how???
Answer: See below
Explanation:
For this question, we are given the volume, and we want to find the diameter. We have to work backwards to get our radius, then to find the diameter.
[tex]V=\pi r^2h[/tex] (Volume of cylinder)
[tex]72\pi =\pi r^2h[/tex] (The π cancel out)
[tex]72 =r^2(8)[/tex] (Plug in h=8)
[tex]9=r^2[/tex] (Divide 8)
[tex]r=3[/tex] (Square root of 9 is 3)
Now that we have our radius, we can find our diameter.
[tex]d=2r[/tex] (Equation for diameter)
[tex]d=2(3)\\[/tex] (Plug in r=3)
[tex]d=6yards[/tex] (Multiply)

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%

how can i raise my gpa from 1.3 to 4.0?
Answer:
study
Explanation:
Well to be honest, this could be rather difficult depending on what year of school you are in; however all good things take a little effort!
Having such a high goal is very good, but start with small goals that will lead you to the overall achievement. 4.0 is an A average and getting to that from a 1.3 (D average) may be difficult, not impossible though! Like the person above stated studying is going to be a big part of this journey. Taking alot of time to focus on bringing grades up and your schoolwork will help you in the long run. Try talking to your teacher(s) about any low grades you could bring up with extra credit or even retaking or redoing any assignments or exams you may have done less than ideal on. My biggest tip for keeping your grades up is to make sure you ask for help if you dont understand. I have found myself too many times not asking for help for a variety of reasons and I ALWAYS pay for it after the fact. Your assignments and exams directly reflect your knowledge of the subjects; if you dont understand it, then you wont do well. Another tip that will help you keep up your grades is... DON'T PROCRASTINATE! I am personally the biggest procrastinator ever; I basically do it for a living at this point. So take it from me, its never a good idea. You will always regret it and it will show in your grades. I hope this helps a little bit! Good luck!
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.

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.

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]
