What’s the y-intercept of this graph
Answers
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
Finding the slope:
So first it'll help to find the slope. You could do that by finding two perfect points, which in my case I chose (3,4) and (4,2). Then you tell what the rise over run is....you go down 2 and right 1 to get from (3,4) to (4,2). So the slope would be -2, since we went down it'll become a negative.
Finding the y-intercept:
Then after we found the slope we could easily make an equation and solve it for the y-intercept, but first we'll need to get a point. Let's choose (4,2). So after you got your point you will plug it into the slope formula like this....
[tex]y=mx+b\\\\\\2=-2(4)+b[/tex]
Then we solve it to get....
[tex]2=-2(4)+b\\2=-8+b\\b=10[/tex]
So the y-intercept is 10.
The football team at a high school wants to conduct a survey of student opinion. The coaches want to begin with a simple random sample of 200 students. Which of the following survey methods will produce a simple random sample?
Survey the first 200 students to arrive at school in the morning
Survey every 20th student entering the school gym until 200 students are surveyed
Number the students on the school roster. Use a table of random numbers to choose 200 students from this roster for the survey.
Use random numbers to choose 50 each of freshmen, sophomores, juniors, and seniors
Number the gym seats. Use a table of random numbers to choose seats and interview the students until 200 have been interviewed.
Answers
Answer: Number the students on the school roster. Use a table of random numbers to choose 200 students from this roster for the survey.
Step-by-step explanation:
A truly random sample would be one that gave every member of the population the same chance to be represented. This is why the method that will produce a simple random sample is one where the official school rooster is used and 200 students are selected randomly. This way every student in the school gets an equal chance of representation.
The first option is not random as it excludes students arriving after the first 200.
The second and last options will not be representative nor will it be random because it does not account for students who do not use the gym.
The fourth option limits the number of people that may be picked per class so reduces the chance of simple random selection across the school. This is stratified instead.

A rope for zip lining is tied between two parallel trees. The rope is taut, forming a straight line. What is m<2?
Answers
Answer:
72°.
Consecutive interior angle
Step-by-step explanation:
The complete question is shown below
The consecutive interior angle theorem states that if two parallel lines are cut by a transversal line, the pair of interior angles formed are supplementary (that is they sum up to 180°).
Hence since the two trees are parallel and the rope forms a transversal hence they form an interior angle:
m∠2 + 72° = 180° (consecutive interior angles)
Add -72 to both sides and then simplify:
m∠2 + 72 -72 = 180 - 72
m∠2 = 108°

12. Dominic drives a taxi. He charges a $2 flat fee plus $1.50 per mile.
The table represents f(x), a function that can be used to predict the
total cost of any trip in Dominic's taxi.
Answers
Answer:
The y-intercept represents the flat fee.
Step-by-step explanation:
The y-intercept on the graph would be the point at which the line cuts across or intercepts the y-axis. At this point, the value of x (miles travelled) would be 0. The y-intercept in this case, would be the flat fee which is given as $2.
At x = 0, f(0) = 2.
The y-intercept represents the flat fee on the graph of f(x).

Arrivals at a parking lot are assumed to follow the Poisson distribution. The average arrival rate is 2.8 per minute. What is the probability that during a given minute no cars will arrive
Answers
Answer:
[tex]P(x = 0) = 0.061[/tex]
Step-by-step explanation:
Given
[tex]Average = 2.8[/tex]
Required
Determine the probability that no car will arrive.
Since it is a Poisson distribution, the required probability is:
[tex]P(x) = \frac{e^{-m}m^x}{x!}[/tex]
Where
[tex]m = average = 2.8[/tex]
In this case;
[tex]x = 0[/tex]
So:
[tex]P(x) = \frac{e^{-m}m^x}{x!}[/tex]
[tex]P(x = 0) = \frac{e^{-2.8}2.8^0}{0!}[/tex]
[tex]P(x = 0) = \frac{e^{-2.8}*1}{1}[/tex]
[tex]P(x = 0) = e^{-2.8}[/tex]
[tex]P(x = 0) = 0.06081006262[/tex]
[tex]P(x = 0) = 0.061[/tex] --- Approximated

Read Edward Corsi’s quotation from the book Immigrant Kids by Russell Freedman. The writer Angelo Pellegrini has recalled his own family’s detention at Ellis Island: We lived there for three days - Mother and we five children, the youngest of whom was three years old. Because of the rigorous physical examination that we had to submit to, particularly of the eyes, there was this terrible anxiety that one of us might be rejected. And if one of us was, what would the rest of the family do? This quotation adds credibility to the text because his mother lived on Ellis Island with her children, and their experience agrees with Freedman’s statement that families were separated. he lived at Ellis Island for three days, and his experience agrees with Freedman’s statement that families were afraid of the health examinations. he was a writer who wrote about Ellis Island and described the feelings an immigrant might have during the physical exams. he lived at Ellis Island for three days, a

If the population proportion p = 0.63, what is the probability of getting correct answers on less than 60% of the questions?
Answers
Complete question:
An exam consists of 50 multiple choice questions. Based on how much you studied, for any given question, you think you have a probability of 0.63 of getting the correct answer. Consider the sampling distribution of the sample proportion of correct questions out of 50.
If the population proportion p = 0.63, what is the probability of getting correct answers on less than 60% of the questions?
Answer:
the probability of getting correct answers on less than 60% of the questions is 0.33
Step-by-step explanation:
Given;
number of samples, n = 50
population proportion, P = 0.63
For normal distribution;
np ≤ 60 and n(1-p) ≤ 60
(50 x 0.63) ≤ 60 and (1-0.63) ≤ 60
31.5 ≤ 60 and 22.2 ≤ 60
The condition is satisfied, then mean of the distribution is given by;
x = p = 0.63
The standard deviation is given by;
[tex]\sigma_p =\sqrt{\frac{P(1-P)}{n} }\\\\ \sigma_p =\sqrt{\frac{0.63*0.37}{50} }\\\\ \sigma_p = 0.068[/tex]
For a correct answers on less than 60% of the questions
Upper boundary = 0.6
lower boundary = 0
Thus, the probability is given by;
P (p' < 0.6) = 0.33
Therefore, the probability of getting correct answers on less than 60% of the questions is 0.33

Consider the following information about travelers (based partly on a recent Travelocity poll): 40% check work e-mail, 30% use a cell phone to stay connected to work, 25% bring a laptop with them, 23% both check work e-mail and use a cell phone to stay connected, and 51% neither check work e-mail nor use a cell phone to stay connected nor bring a laptop. Finally, 88 out of every 100 who bring a laptop check work e-mail, and 70 out of every 100 who use a cell phone to stay connected also bring a laptop.
(a) What is the probability that a randomly selected traveler who checks work e-mail also uses a cell phone to stay connected?
(b) What is the probability that someone who brings a laptop on vacation also uses a cell phone to stay connected?
(c) If a randomly selected traveler checked work e-mail and brought a laptop, what is the probability that s/he uses a cell phone to stay connected?
Answers
Step-by-step explanation:
I defined the following events:
J = travellers check email
K = they use a cell phone to stay connected
M = they have a laptop alongside
P(J) = 0.40
P(K) = 0.30
P(M) = 0.25
P(J n K) = 0.23
P(J U K U M)' = 0.51
P(J|M) = 0.88
P(M|K) = 0.70
A.
We are to find probability of K|J
P(JnK)/p(J)
= 0.23/0.40
= 0.575
B.
P(K|M)
= P(KnM)/P(m)
= 0.21/0.25
= 0.84
C.
P(J U K U M) = 1 - p(J U K U M)'
= 1-0.51
= 0.49
P(JnM) = p(J|M)p(M)
=0.88x0.25
= 0.22
P(JnKnM) = 0.49-0.40-0.30-0.25+0.23+0.22+0.21
= 0.20
P(K|JnM) = P(JnKnM)/p(JnM)
= 0.20/0.22
= 0.909
