You are comparing phone plans. Q company charges a one time fee of $25 and then $3 per month. W company charges a one time fee of $60 and then $1 per month. How many months until the two companies have the same cost
Answers
Answer:
17 1/2 months or rounded up to 18
Step-by-step explanation:
so first you need to set up an equation,
lets do company Q first..
because the monthly fee is 3 bucks thats gonna be the number that goes hand in hand with x so lets put that down
Q - 3x
now we have to add our one time fee of 25 dollars
Q - 3x + 25 .. bam thats our first equation
lets do the same thing for our next company
W - x + 60
( because the fee is one dollar, theres no reason to put 1x, its not mathematically correct, so we just leave it as x )
so now we have to set up the equation together, and because we are trying to find when the two will meet and have an EQUAL cost we make them equal to each other
so
3x + 25 = x + 60
if you solve it...
2x + 25 = 60
2x + 35
x = 17.5

The relationship between the distance run and the time for Amy can be represented by the equation Y equals 17.45X, where she ran Y meters in X seconds. which two equations could be used to represent the relationship for Brandon and Ruben
Answers
Question;
Assumption:
Let us assume Brandon's running speed is = 18.30 and
Ruben's running speed is = 16.50 and
Answer:
The two equations that can represent the relationship between the meters and second for Brandon and Ruben are;
Brandon → Y₁ = 18.3·X₁ and
Ruben → Y₂ = 16.5·X₂
Step-by-step explanation:
The equation is of the form
Y = 17.45·X
That is Amy ran Y meters in X seconds
Therefore we have
[tex]17.45 = \frac{Y}{X}[/tex] or the value 17.45 is the running speed of Amy
Therefore, where the running speed of Brandon is 18.30 and the running speed of Ruben is 16.50 we have
Y meters ran by Brandon in X seconds given by
Y₁ = 18.3·X₁ and
For Ruben we have Y meters ran in X seconds given by
Y₂ = 16.5·X₂.
Answer:
Brandon : Y = BX, where B is the speed (positive integer) and X is the time in seconds.
Ruben : Y = RX, where R is the speed (positive integer) and X is the time in seconds.
Step-by-step explanation:
For Amy, the relationship between the distance run and the time taken is represented by the equation Y equals 17.45X, where she ran Y meters in X seconds.
Therefore we have,
Y = 17.45X
Y/X = 17.45 m/s, where m/s is meter per second.
Let us assume that the speed for Brandon is represented by B and that of Ruben is represented by R.
For Brandon, we obtain Y/X = B m/s
Y = BX
For Ruben, we obtain Y/X = R m/s
Y = RX

Suppose 20% of the population are 65 or over, 26% of those 65 or over have loans, and 53% of those under 65 have loans. Find the probabilities that a person fits into the following categories. (a) 65 or over and has a loan (b) Has a loan (c) Are the events that a person is 65 or over and that the person has a loan independent? Explain.
Answers
Answer:
(a)The probability that a person 65 or over and has a loan is 0.052.
(b)The probability that a person 65 or over and has a loan is 0.476
(c) The probability that a person is 65 or over and has a loan independent is 0.0952
Step-by-step explanation:
Conditional probability:
Let A and B any two event is connected to a given random experiment E. The conditional probability of the event A on the hypothesis that the event B is occurred, denoted by P(A|B), is defined as,
[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}[/tex]
So, P(A∩B) = P(B).P(A|B)
Given that,
The age of 20% of population are 65 years or over.
26% of those whose age 65 years or more have loans.
53% of those whose age under 65 years have loans.
E= the person is 65 or more.
F= the person has loan.
P(E)= 20%=0.2
P(F|E)=26%=0.26
P(F|E')=53%=0.53
So,
P(E')=1-0.2=0.8
P(F'|E)= 1-0.26=0.74
P(F'|E')= 1-0.53=0.47
(a)
The probability that a person 65 or over and has a loan is
=P(E∩F)
=P(F|E).P(E)
=0.26×0.2
=0.052
(b)
A person who has a loan either 65 or more , or under 65.
P(F)= P(F∩E)+P(F∩E')
=P(F∩E)+P(E').P(F|E')
= 0.052+ (0.8).(0.53)
=0.476
(c)
Independent event:
If A and B are two independent event,
Then,P(A∩B)=P(A).P(B)
The probability that a person is 65 or over and has a loan independent is
=P(E∩F)
=P(E).P(F)
=(0.2)×(0.476)
=0.0952
The probability that a person is 65 or over and has a loan is 0.052, the probability that a person has a loan is 0.476, and the probability that a person is 65 or over and that the person has a loan independent is 0.0952.
Given :
Suppose 20% of the population are 65 or over, 26% of those 65 or over have loans, and 53% of those under 65 have loans.
Let A represent the person who is 65 or more and B represents the person who has a loan.
If (P(A) = 20% = 0.2) then (P(A') = 1 - 0.2 = 0.8)
If (P(B|A) = 26% = 0.26) then (P(B'|A) = 1 - 0.26 = 0.74)
If (P(B|A') = 53% = 0.53) then (P(B'|A') = 1 - 0.53 = 0.47)
a) The probability that a person is 65 or over and has a loan is:
[tex]\rm = P(A\cap B)[/tex]
[tex]\rm = P(B|A)\times P(A)[/tex]
[tex]=0.26\times 0.2[/tex]
= 0.052
b) The probability that a person has a loan is:
[tex]\rm P(B) = P(A\cap B)+P(B\cap A')[/tex]
[tex]\rm = P(B \cap A)+P(A')\times P(B|A')[/tex]
[tex]=0.52+0.8\times 0.53[/tex]
= 0.476
c) The probability that a person is 65 or over and that the person has a loan independent is:
[tex]= \rm P(A\cap B)[/tex]
= P(A).P(B)
= (0.2)[tex]\times[/tex](0.476)
= 0.0952

(b) Suppose a random sample of 40 houses are selected from the city. Estimate the probability that the mean value of the 40 houses is less than $500,000. Show your work.
Answers
Answer:
a) 0.71
b) 0.9863
Step-by-step explanation:
a. Given the mean prices of a house is $403,000 and the standard deviation is $278,000
-The probability the probability that the selected house is valued at less than $500,000 is obtained by summing the frequencies of prices below $500,000:
[tex]P(X<500,000)=P(X=0)+P(X=500)\\\\=0.34+0.37\\\\=0.71[/tex]
Hence, the probability of a house price below $500,000 is 0.71
b. -Let X be the mean price of a randomly selected house.
-Since the sample size 40 is greater than 30, we assume normal distribution.
-The probability can therefore be calculated as follows:
[tex]P(X<x)=P(z<\frac{\bar X-\mu}{\sigma/\sqrt{n}})\\\\P(X<500,000)=P(z<\frac{500-403}{278/\sqrt{40}})\\\\=P(z<2.2068)\\\\\\=0.9863[/tex]
Thus, the probability that the mean value of the 40 houses is less than $500,000 is 0.9863

Answer:
(B) median because there is an outlier
Step-by-step explanation:
The given data is as follows:
{1, 4, 9, 4, 10, 8, 42}
We can see from the given data that 42 is a data point which differ greatly from the other data points, and from the definition of OUTLIER that is a data point that differ greatly from the trend expressed by the other values in the data set.
Thus, 42 is an outlier.
Now, We have to find the center for the given data set, thus we will use the median as the definition of median states that median is the middle value of the data set.
Therefore, the best measure to find the center of the given data will be median because there is an outlier 42 present in it.

Lou has a solid clay brick in the shape of a rectangular prism with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches. If the clay weighs 1.055 oz/in^3, how much does Lou's brick weigh, to the nearest ounce?
Answers
Answer:
The weight of the brick is 60 ounce to the nearest ounce
Step-by-step explanation:
In this question, we are asked to calculate the weigh of Lou’s brick given the dimensions of the shape of the brick and the weight of the clay.
To answer this question quite aptly, we need to know exactly the volume of the rectangular prism given the dimensions we have in the question.
To calculate this volume , we simply use the measurements we have to get it.
mathematically the volume of a rectangular prism is simply V = w * h * l
where w , h and l are width, height and length respectively.
now let’s calculate!
V = 3.5 * 2.25 * 8 = 63 inches^3
Now we need to know what the brick weigh in ounce. We already have the weight of the clay. now this is equal to the volume of the brick divided by the weight of the clay.
Mathematically this is = 63/1.055 = 59.72 ounce which is 60 ounce to the nearest ounce
Answer:
60 ounce
Step-by-step explanations:
The volume of a rectangular prism is length multiplied by width and the height.
And if the width is 3.5 inches
Length is 8 inches
Height of 2.25 inches
V = 2.25 × 8 × 3.5
= 63 in³
And since the clay weighs 1.055 oz/in³,the total weight of the clay brick will be derived by dividing the volume of the brick by its weight per in³
63/1.055
= 59.7 and to the nearest whole number = 60 ounce
