Answer:
[tex]c=-10.4[/tex]
[tex]c=-\frac{52}{5}[/tex]
Step-by-step explanation:
Hello! You did not provide given values, but we can go through this together without any given choices.
Start with:
[tex]5c-5=-50-7[/tex]
Combine like terms:
[tex]5c-5=-57[/tex]
Add [tex]5[/tex] to both sides of the equation:
[tex]5c=-52[/tex]
Divide both sides of the equation by the coefficient of [tex]c,[/tex] which is [tex]5[/tex]:
[tex]c=-10.4[/tex]
- or -
[tex]c=-\frac{52}{5}[/tex]

fran drank 19/20 liter of juice how many quarts of juice did she drink (1 L =1.06qt). set up a proportion and solve using means of extremes
Given :
Fran drank 19/20 liter of juice.
1 L = 1.06 qt.
To Find :
How many quarts of juice did she drink.
Solution :
It is given that :
[tex]1 \ L=1.06\ qt\\\\1=\dfrac{1.06\ qt}{L}[/tex]
Now, amount of water he drink :
[tex]\dfrac{19}{20}\times 1 \ L\\\\\dfrac{19}{20}\times 1.06\ \dfrac{qt}{L}\times L\\\\\dfrac{19}{20}\times 1.6 \ qt\\\\1.52\ qt[/tex]
Hence, this is the required solution.

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.
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.
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
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

Select ALL of the perfect squares
6
100
25
5
Answer:
100 and 25 are the perfect squares
Our answers are 100 and 25.
Some insight:
6 = [tex]\sqrt{6}*\sqrt{6}[/tex] -- We cannot simplify the square root of 6 to integers, so no.
100 = [tex]\sqrt{100}* \sqrt{100}[/tex] = 10*10 -- This is a perfect square
25 = [tex]\sqrt{25}* \sqrt{25}[/tex] = 5*5 -- This is a perfect square
5 = [tex]\sqrt{5}* \sqrt{5}[/tex] -- No.

If the population proportion p = 0.63, what is the probability of getting correct answers on less than 60% of the questions?
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

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.
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).
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?
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

what is a positive - negative
Answer:
Numbers can either be positive or negative. ... Adding and multiplying combinations of positive and negative numbers can cause confusion and so care must be taken. Addition and Subtraction. Two 'pluses' make a plus, two 'minuses' make a plus. A plus and a minus make a minus.
