museum, A chaperone is needed for every 10 students. Each bus can hold 40 people. The principal
writes the equation 40b=114+114/10 to find the number of buses necessary, b.
How many buses are needed to carry everyone? Justify your answer.
Answer:
4 buses
Step-by-step explanation:
40b=114+114/10
40b=114+11.4
40b=125.4
b=3.135
The answer is 4 because you have to round up to get the remaining people.

solve 2m-44=76-8m and give the right answer
Answer:
m = 12
Step-by-step explanation:
2m − 44 = 76 − 8m
Move all terms containing m to the left side of the equation
10m − 44 = 76
Add 44 to both sides of the equation
10m = 120
Divide each term by 10 and simplify.
10m/10 = 120/10
m = 12
Answer:
[tex]\boxed{m = 12}[/tex]
Step-by-step explanation:
[tex]2m-44=76-8m[/tex]
Simplify both sides of the equation.
[tex]2m + -44 = 76 + -8m[/tex]
[tex]2m - 44 = -8m + 76[/tex]
Add 8m to both sides.
[tex]2m - 44 + 8m = -8m + 76 + 8m[/tex]
[tex]10m - 44 = 76[/tex]
Add 44 to both sides.
[tex]10m - 44 + 44 = 76 + 44[/tex]
[tex]10m = 120[/tex]
Divide both sides by 10.
[tex]\frac{10m}{10} = \frac{120}{10}[/tex]
[tex]m= 12[/tex]

For which data set is a linear regression most reasonable? A. A set of nine data pairs with a correlation coefficient r = –0.4 B. A set of five data pairs with a correlation coefficient r = 0.3 C. A set of four data pairs with a correlation coefficient r = –0.8 D. A set of six data pairs with a correlation coefficient r = 0.6
Answer:
Set of four data pairs with correlation coefficient r= -0.8 reasonable linear regression data set.
Step-by-step explanation:
Linear regression is a primary type of predictive analysis. It describes does a variable does a useful job. Which variable is significant.
Set of nine data pairs with correlation coefficient r = -0.4
Set of five data pairs with correlation coefficient r= 0.3
Set of four data pairs with correlation coefficient r= -0.8
Setoff six data pairs with correlation coefficient r = 0.6
A setoff four data pair with correlation coefficient r = -0.8 is the valid data set.
Because
r = -0.8
r2 = 0.64,
This is very close to 1 as compared to any other data pair.
Hence, Set of four data pairs with correlation coefficient r= -0.8 reasonable linear regression data set.
Answer:
C "a set of four data pairs with a correlation coefficient r = –0.8"

ed a Hint
Answer:
0.0520
Step-by-step explanation:
In this expression, we conclude that 1 is the least significant figures after decimal in this problem. The answer will be 0.0520.
What is Significant figures?Significant figures is the figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the multiplication and division is that the least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The rule apply for the addition and subtraction is that the least precise number present after the decimal point determines the number of significant figures in the answer.
The given expression is: 0.0702 - 1.35
0.0702 - 1.35
= 0.0520
In this expression, we conclude that 1 is the least significant figures after decimal in this problem.
The answer will be 0.0520.

A marathon runner ran 15 miles in 120 minutes. What is the ratio of minutes per mile?
Answer:
Step-by-step explanation:
Answer: So that means it would take him 7.9 minutes to run a mile
Step-by-step explanation:
Divide your run distance by your run time.
If you ran 2.5 miles and you ran for 20 minutes: 2.5 mi ÷ 20 min = 0.125 miles per minute. So the answer would be
15 miles= 79200
79200 divided by 120=660
