Step-by-step explanation:
In a logistic regression model, the predictor _________
a. is interval/ratio data.
b. must undergo a logarithmic transformation before undergoing logistic regression.
c. must be in the range of 0 to 1
d. represents ranked scores
e. must be a binary variable
Answer:
B. must undergo a logarithmic transformation before undergoing logistic regression.
Step-by-step explanation:

Marcus expects to earn about $10,000 in sales per month.
He can choose Salary A of $1,500 plus 5.5% of sales which will make him $2050 each month.
Salary B offers $2400 plus 3% of sales. How much does Salary B offer Marcus each month?
Which salary option should he choose: A or B?
Answer:
A
Step-by-step explanation:
5.5 x 2050 = 11,275
In a dance contest in which 53,000 votes were cast, the winner received 3/5 of votes. How many votes did the winner not receive? (Incorrect solution: 3/5 x 53,000 = 3/5 x 53,000/1 = 3x53,000/ 5 x 1 = 31,800) ( explain error please and add correct work/solution and if you could share a strategy you used? Thanks!!)
Answer:
21,200
Step-by-step explanation:
Votes casted = 53000
Votes received = 3/5
Votes did not receive = 1- 3/5 = (5-3)/5 = 2/5
Total votes not received by winner
= 53000 *2/5
= 10,600 * 2
= 21,200

Ms. Van Tress has 134 students. She sees 38 students before lunch and 96 students after lunch.
What percentage of her students does she see before lunch? After lunch? (Round your answers to
the nearest whole number percent)
Answer:
[tex]\%Percent = 28\%[/tex] ---- Before Lunch
[tex]\%Percent = 72\%[/tex] --- After Lunch
Step-by-step explanation:
Given
[tex]Total = 134[/tex]
[tex]Before\ Lunch = 38[/tex]
[tex]After\ Lunch = 96[/tex]
Required
Determine the percentage of students seen in both cases.
This percentage is calculated by dividing the number of students seen by the total number of students. Then multiplied by 100%
i.e
[tex]\%Percent = \frac{Seen}{Total} * 100\%[/tex]
- Before Lunch;
[tex]\%Percent = \frac{Before\ Lunch}{Total} * 100\%[/tex]
[tex]\%Percent = \frac{38}{134} * 100\%[/tex]
[tex]\%Percent = \frac{3800\%}{134}[/tex]
[tex]\%Percent = 28\%[/tex] --- approximated
- After Lunch;
[tex]\%Percent = \frac{After\ Lunch}{Total} * 100\%[/tex]
[tex]\%Percent = \frac{96}{134} * 100\%[/tex]
[tex]\%Percent = \frac{9600\%}{134}[/tex]
[tex]\%Percent = 72\%[/tex] --- approximated

Melissa multiplied [tex]\sqrt{a}[/tex] and [tex]\sqrt{b}[/tex] and got a rational number.
We are also given that a and b are both natural numbers. It means their product must be not only rational but also a natural number.
We can write that product like:
[tex]\sqrt{a} \cdot \sqrt{b}=\sqrt{a\cdot b}[/tex]
If the result is a natural number, then the product of a and b must be a perfect square. so the radical disappears.

1) You are taking a Tae Kwon Do class that costs $15 a month. In addition, you needed to
purchase a uniform. You paid a total of $108 after 6 months. Write an equation that glves
the total cost (in dollars) as a function of the length of time you have been taking classes
(in months). Find the total cost after 9 months.
Answer:
$162
Step-by-step explanation:
you divide 6 months by 2 then you divide 108 by 2 then you add the half of 108 and plus it to 108 then you get your total.
The function of the length of time you have been taking classes is f(x) = 15x and cost for 9 months is $135
What is unit rate?A unit rate means a rate for one of something.
Given that, You are taking a TAE Kwan Do class that costs $15 a month. In addition, you needed to purchase a uniform. You paid a total of $108 after 6 months.
We have unit rate = $15 per month
Since, one month cost is $15 therefore, for 6 months = 15×6 = $90
Therefore, cost of uniform = $108 - $90 = $18
Let you are taking classes for x months, the function of the length of time you have been taking classes,
f(x) = 15x
For 9 month cost =
f(9) = 15×9 = 135
Hence, the function of the length of time you have been taking classes is f(x) = 15x and cost for 9 months is $135

Slope is 0
Use point-slope form.
y-y1=m(x-x1)

STEAM: The boiling pint of water is affected by changes in elevation. Use the expression of -2A/1000 where a represents the altitude in feet to find the number of degrees Farenhite at which the boiling point of water changes at altitude 5,000 feet
A) -10°F B) 20°F C) 10°F D) -20°F
Answer:
A) -10°F
Step-by-step explanation:
Given that:
Boiling point of water gets affected when there is a change in the elevation.
Expression to represent the temperature i.e. boiling point w.r.to altitude [tex]A[/tex] is given by the equation:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
Given that, the altitude, [tex]A[/tex] = 5,000 feet
To find:
The number of degrees Farenhite at which the boiling point of water will change.
Solution:
Here, we are given the expression:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
And value of altitude, [tex]A[/tex] = 5,000 feet
Let us put the value of [tex]A[/tex] in the equation and let us find the value of temperature in [tex]^\circ F[/tex].
Temperature in [tex]^\circ F[/tex] =
[tex]\frac{-2\times 5000}{1000}\\\Rightarrow -2\times 5\\\Rightarrow \bold{-10^\circ F}[/tex]
Therefore, the answer is:
A) -10°F

Answer:
θ = cos-1 (38/47)
Step-by-step explanation:
sin θ = [tex]\frac{opposite}{hypotenuse} = \frac{27}{47}\\[/tex]
θ = sin-1 (27/47)
cos θ = [tex]\frac{adjacent}{hypotenuse} = \frac{38}{47}[/tex]
θ = cos-1 (38/47)
tan θ = [tex]\frac{opposite}{adjacent} = \frac{27}{38}[/tex]
θ = tan-1 (27/38)
