Answer: Regression with sales as the dependent variable
Step-by-step explanation:
Since the franchise company wanted to determine why sales were higher at some locations rather than others, the statistical process that would be most appropriate is regression with sales as the dependent variable.
Regression will be used in determining the strength of the relationship that exist between one dependent variable and the independent variables. In this case, the dependent variable is sales.

If f(x)=x^2−8x and g(x)=−12x^2 what is g(f(−4))?
Answer:
-27648
Step-by-step explanation:
In this problem, we are looking for the function of g in terms of the function f. Simply put, we just replace the variable x in the function g with f(-4).
Step 1, writing g(f(-4)):
[tex]g(f(-4))=-12(f(x))^2[/tex]
Great! Let us substitute f(x) with the given expression.
Step 2, substituting and simplifying:
[tex]\\g(f(-4))=-12(x^2-8x)^2\\g(f(-4))=-12((-4)^2-8*(-4))^2\\g(f(-4))=-12(16+32)^2\\g(f(-4))=-12*2304\\g(f(-4))=-27648[/tex]
g(f(-4) is [tex]\fbox{-27648}[/tex].

What is the probability of flipping a coin 10 times and getting heads 5 times? Round your answer to the nearest tenth percent.
The Probability is 1/2 or .5, .5 rounded to the nearest tenth would be irregular because .5 is already in the tenth place but according to the law of rounding since ut is five it would be rounded up giving the whole number 1
The initial number of views for a reader board is 25. The number of views is growing exponentially at a rate of 18% per week. What is the number of views expected to be four weeks from now?
Answer:
48
Step-by-step explanation:
n = 25(1.18)^4
n = 48.469444
Rounded to 48
Answer:
48 views.
Step-by-step explanation:
18% = 0.18 as a decimal fraction.
The increase in number of books per week is found by multiplying by 1.18.
The equation is an exponential one and is:
V = 25(1.18)^t where V = views and t = number of weeks.
So after 4 weeks :
V = 25 (1.18)^4
= 48.47

Suppose we are sending a digital signal which is a string of 0s and 1s of length five. (Example stringsare 00101, 11000, 10101 are all 5 bit strings.) When we send the message, each bit (0 or 1) is sentindependently and there is some chance that the bit is corrupted. Namely, each time we send a 0 thereis a 5% chance that a 1 is received and each time we send a 1 there is a 5% chance a 0 is received.Suppose we send a message of length 5, what is the probability that an incorrect message is received
Answer:
0.7738 = 77.38% probability that an incorrect message is received.
Step-by-step explanation:
For each bit, there are only two possible outcomes. Either it is corrupted, or it is not. The probability of a bit being corrupted is independent of any other bit. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
5% probability a bit is sent incorrectly:
This means that [tex]p = 0.05[/tex]
Message of length 5
This means that [tex]n = 5[/tex]
What is the probability that an incorrect message is received?
This is the probability of at least one incorrect bit, which is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{5,0}.(0.05)^{0}.(0.95)^{5} = 0.7738[/tex]
0.7738 = 77.38% probability that an incorrect message is received.
Assume that you purchased a new car today and financed $55,000 of the price on a 72-month payment contract with a nominal rate of 6.00%. Further, assume that you plan on paying off the balance of the car loan after you make your 48th payment. How much will your loan balance be when you pay off the car?
Answer:
The amount that your loan balance will be when you pay off the car is $20,566.18.
Step-by-step explanation:
Step 1. Calculation of monthly payment
This can be calculated using the formula for calculating the present value of an ordinary annuity as follows:
PV = P * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)
Where;
PV = Present value or the cost of the new car = $55,000
P = Monthly payment = ?
r = Monthly nominal rate = Nominal rate / 12 = 6% / 12 = 0.06 / 12 = 0.005
n = number of months = 72
Substitute the values into equation (1) and solve for P, we have:
$55,000 = P * ((1 - (1 / (1 + 0.005))^72) / 0.005)
$55,000 = P * 60.3395139355201
P = $55,000 / 60.3395139355201 = $911.51
Step 2. Calculation of the loan amount balance when you pay off the car
This can be calculated using the ballon payment formula as follows:
P = (PV - (Ballon / (1 + r)^n)) * (r / (1 – (1 + r)^-n)) ...................... (1)
Where:
P = Monthly payment = $911.51
PV = Present value or the cost of the new car = $55,000
Ballon = Ballon payment or the loan amount balance when you pay off the car = ?
r = Monthly nominal rate = Nominal rate / 12 = 6% / 12 = 0.06 / 12 = 0.005
n = number months to pay off the loan amount balance = 48
Substituting the values into equation (1) and solve for Ballon, we have:
911.51 = (55,000 - (Ballon / (1 + 0.005)^48)) * (0.005 / (1 - (1 + 0.005)^-48))
911.51 = (55,000 - (Ballon / 1.27048916109538)) * 0.0234850290479363
911.51 / 0.0234850290479363 = 55,000 - (Ballon / 1.27048916109538)
38,812.39 = 55,000 - (Ballon / 1.27048916109538)
Ballon / 1.27048916109538 = 55,000 - 38,812.39
Ballon / 1.27048916109538 = 16,187.61
Ballon = 16,187.61 * 1.27048916109538
Ballon = $20,566.18
Therefore, the amount that your loan balance will be when you pay off the car is $20,566.18.
what is the best estimate of (-3/8)(17 5/6)
Answer:
-11
Step-by-step explanation:
Given the expression (-3/5)(17 5/6)
Converting the mixed to improper fraction
(-3/5)(17 5/6)
= (-3/5)(107/6)
= (-3*107)/(5*6)
= -321/30
= -10.7
Hence the required best estimate is -11
Show that the transformation T defined by T(x1, x2)= (x1x2, x1, x2) is not linear. If T is a linear transformation, then T(0)= ____________
Answer:
A linear transformation is defined as:
For a transformation T that goes from R^n to R^m, this transformation is linear if, for two vectors A and B, we have that:
T(A + B) = T(A) + T(B)
In this case, we have the transformation:
T(x1, x2)= (x1x2, x1, x2).
If we define two vectors:
A = (a1, a2)
B = (b1, b2)
if the transformation is lineal, we will have that:
T(A + B) = T(A) + T(B)
Or
T(0) = T(A - A) = T(A) + T(-A)
(just two different ways of writing the same thing, I will use the first one, because it is the general way)
We want to see that, for our transformation, this equation is false.
first the left side:
A + B = (a1, a2) + (b1, b2) = (a1 + b1, a2 + b2)
Then the transformation applied to that vector gives:
T(A + B) = T(a1 + b1, a2 + b2) = ( (a1 + b1)*(a2 + b2), (a1 + b1), (a2 + b2))
= (a1*a2 + a1*b2 + b1*a2 + b1*b2, a1 + b1, a2 + b2)
While for the right side, we have:
T(A) + T(B) = T(a1, a2) + T(b1, b2) = (a1*a2, a1, a2) + (b1*b2, b1, b2)
= (a1*a2 + b1*b2, a1 + b1, a2 + b2)
Then we can rewrite:
T(A + B) = T(A) + T(B)
as:
(a1*a2 + a1*b2 + b1*a2 + b1*b2, a1 + b1, a2 + b2) = (a1*a2 + b1*b2, a1 + b1, a2 + b2)
We can see that the first part of these vectors is different, thus, the equality is false.
Then we can conclude that:
T(A + B) ≠ T(A) + T(B)
Then the transformation T is not linear.

Answer:
Paige is incorrect. g(x) has a steeper slope
Step-by-step explanation:
The slope for f(x) is
m =( y2-y1)/(x2-x1)
= (17/2 - 5/2) / ( -1 - -6)
= (17/2 - 5/2) / ( -1 +6)
= (12/2)/5
= 6/5
The slope for g(x) is
m =( y2-y1)/(x2-x1)
= (-1 - 13/3) / ( 6 - 2)
=(-3/3 -13/3) / (6-2)
(-16/3)/4
-16/3 * 1/4
- 4/3
Comparing the magnitudes
|6/5| |-4/3|
|6/5*3/3| |-4/3*5/5|
|18/15| |20/15|
|20/15| is greater so it has a steeper slope
g(x) has a steeper slope

I took 18 pencils from the box. this is equivalent to 2/5 of the total number of pencils.
How many pencils were there in the box originally. Show your work.
Answer: 45 pencils were in the box originally
Step-by-step explanation:
Suppose there were x pencils in the box originally. Since 18 pencils is equal to 2/5 of the total number of pencils in the box originally, set 18 equal to 2/5x or
18=2/5x
Now solve
x = 18x5/2 = 45

Answer:
224 in²
Step-by-step explanation:
There are a couple of ways to go at this. Here, we choose to figure the areas of each of the prisms individually, then subtract the "hidden" area where they are joined together.
The area of a prism is ...
A = 2(LW +H(L+W))
Pink area:
A = 2(10·4 +2(10+4)) = 2(40 +28) = 136 . . . square inches
Green area:
A = 2(7·4 +4(7+4)) = 2(28 +44) = 144 . . . square inches
One 4 in × 7 in face of the green prism meets with a similar area of the pink prism, so the area hidden at that interface is 2(4·7) = 56 square inches. Then the total surface area of the composite figure is ...
SA = 136 in² +144 in² -56 in² = 224 in²
