Answer:
multiple regression
Step-by-step explanation:
In the field of statistics, the multiple regression is the statistical technique which uses the various explanatory variables for predicting the outcome of the response variable. It is the extension of the simple linear regression. It explains the relation between the multiple predictor variables or independent variables and one dependent variable or criterion variable.
In the context, the manager of a tourist company predicting the number of calls to the toll free number is using the statistical technique of multiple regression.
3. The photo below is being enlarged to form
a 16-by 20- inch print. What is the scale
factor being used to enlarge it?
4 in
5 in
Answer:
4 in
Step-by-step explanation:
Given the following data;
Length = 16 in
Width = 20 in
To find the scale factor;
Scale = 16:20
Dividing by 4, we have;
Scale = 4:5
Therefore, the scale factor is 4 in.
Scale = scale factor * ratio
Scale = 4 * (4:5)
Scale = 16:20

Note: Make your final answer clear by writing 'The number is ...'
(the question is formatted a bit weird, but I'm assuming the third statement is meant to be '1/3 of the number is a square number'. If not, let me know and I'll adjust my answer accordingly)
Answer:
The number is 27
Step-by-step explanation:
Let the number be called x.
10% of x is greater than 1 but less than 7. Written mathematically, this is 1<0.1x<7. Multiply this by ten to get 10<x<70.
1/3 of x is a square number. The squares 4, 9, and 16 are the only squares that satisfy this statement, because the if the square was 1, x would be 1, which doesn't fit x>10, and if the square was 25 or higher, x would be greater than 70, which doesn't fit x<70.
x isn't a multiple of six. If the square is 4, x is 12, which is a multiple of six so this doesn't work. If the square is 16, x is 48, which is a multiple of six too, so this doesn't work. But if the square is 9, x is 27, which isn't a multiple of six and satisfies the statement.
Double check that x=27 is a valid answer.
Is 27 a whole number between 1 and 100? Yes
Is 10% of 27 greater than 1 and less than 7? Yes (10% of 27 is 2.7)
Is 1/3 of 27 a square number? Yes (1/3 of 27 is 9, which is the square of 3)
Is 27 not a multiple of 6? Yes (27 isn't divided evenly by 6)
Therefore, the number is 27.
please help me this is confusing please add an explanation to it
Answer:
2
Step-by-step explanation:
As it would look better.
1 would make the graph too big
12 would be useless as there are no "answers" more than 12
10 would be useless too as the biggest number used is 10. therefore, 5, 7 would be cramped and too hard to figure out.

107 > 45+ y hurry pls
Answer:
C. y<62
Step-by-step explanation:
107<45+y
(take 45 from both sides)
62<y, or y>62
The answer of the given inequality is 107>45+y is y<62.
We have given that inequality
107<45+y
What is inequality?
Inequality is a relation that makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
107<45+y
(take 45 from both sides)
Therefore the solution of inequality 62<y, or y>62.

Maria can stuff envelopes twice as fast as her friend James. Together they can stuff 6750 envelopes in 4.5 hours. How long would it take each of them working alone? Which of the following equations could be used to solve this problem?
I thinks it's the last one
hope this helps
Answer:
B. 4.5/t + 4.5/(2t) = 1Step-by-step explanation:
Work = rate*timeMaria's rate = 6750/tJames's rate = 6750/2tTheir rate when working together:
6750/t + 6750/(2t) = 6750/4.5 ⇒ 1/t + 1/(2t) = 1/4.5 ⇒4.5/t + 4.5/(2t) = 1Correct choice is B
( 9 − p ) ( 9 − q ) ( 9 − r ) ( 9 − s ) = 9. What is the value of p + q + r + s ?
p(r + s) = 5 and q(r + s) = 3.
by simply addind those two equations.
p(r + s) + q(r + s) = 5 + 3
(p + q) (r + s) = 8 Statement #2: (p + q) = (r + s)
(p+q)×(r+s)=(p+q)×(p+q)=(p+q
it's been said it's not allowed us to arrive at a specific numerical value. The statementby itself inadequate.

Answer:
c and
28.57%
Step-by-step explanation:
count how many number fall into each category
50-59 has 1
60-69 has 2
70-79 has 4
80-89 has 4
and 90-99 has 3
So the last histogram fits this data
to find the % of those that are between 70-79, take the total number of items that fit into that category (4) and divide by the total number of items (14)
4/14=.2857 --> turn to a percent .2857*100= 28.57%

Answer:
First statement: 10 road workers take 5 days to complete a work, working 2 hours a day.
Let us calculate how many days 2 workers will need, if they were to work at the same pace (i.e. each working 2 hours a day). The workforce is now decreased to 2 divided by 10 = 1/5 (i.e. one-fifth).
Therefore proportionately, the time will increase to 5 days divided by 1/5, (i.e. 5 / (1/5) = 25 days.
We now know that 2 workers will need 25 days to finish the work, if they work for 2 hors a day.
Now the question is what will happen if the two people work 5 hours per day, instead of 2 hours per day?
The labor they put in has increased to 5 divided by 2 = 2.5 (i.e. 2 and half times).
Consequently, the time needed to finish the work will decrease to 25 divided by 2.5 (i.e. ( 25 / 2.5 ) = 10. days.
The answer : 10 Days.
