Answer:
3.7001 × 10 to the power of 4 is the answer for #1
Step-by-step explanation:
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
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"

Amy baked 114 brownies for a bake sale. She sold bags of brownies with
each bag containing 6 brownies. After the bake sale, she had 18 individual
brownies left. Which of the following equations represent b, the number
of bags of brownie Amy sold? *
O 114 = 185 - 6
18 = 6b +114
18 = 114 - 6b
Answer:
18=114-6b
Step-by-step explanation:
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]

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

2) The 114 students in the ninth grade at Mathville High are going on a field trip to the science
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.

Step-by-step explanation:
You"re welcome!
Answer:
Step-by-step explanation:
3/4 - 1/3
lcm of 4 and 3 is 12
so,
3/4 = 3/4 × 3/3 = 9/12
1/3 = 1/3 × 4/4 = 4/12
so, 3/4 - 1/3 = 9/12 - 4/12 = 5/12

Answer: The slope is 3/2 if the given equation is actually this: [tex]y=-\frac{2}{3}x+11[/tex] Not this:
[tex]y=-\frac{2}{3}x+11y= -32[/tex]
Step-by-step explanation:
For perpendicular slopes, use the reciprocal of the given slope and reverse the positive-negative sign (additive inverse
the reciprocal of -2/3 is -3/2 the additive inverse is +3/2
in the diagram below which is not drawn to scale a b is perpendicular to a d if the measurement of CAD is three times measurement of BAC determine the measurement of CAD
Answer:
67.5°
Step-by-step explanation:
From the diagram attached, it can be seen that <BAD = 90° (right angled). Also <BAD = <CAD + <BAC
From the question, we are told that the measurement of CAD is three times measurement of BAC, this means <CAD = 3<BAC
substituting this condition into the formula above:
<BAD = 3<BAC + <BAC
<BAD = 4<BAC
4<BAC = 90
<BAC = 90/4
<BAC = 22.5°
Next is to get <CAD:
<CAD = 3<BAC
<CAD = 3(22.5)
<CAD = 67.5°
Hence the measurement of <CAD is 67.5°
