Answer:

  D.  3, 4, 5, 6

Step-by-step explanation:

  3x + 2 > 8 . . . . . . given

  3x > 6 . . . . . . . . . subtract 2 from both sides

  x > 2 . . . . . . . . . . divide both sides by 2

Any set of values that includes 2 or any smaller numbers is NOT a solution set. The only set with numbers greater than 2 is ...

  D.  3, 4, 5, 6

Why do equivalent ratios form a straight line when graphed?

The vertical distance between points is constant, and the horizontal distance between points increases with each point.

The ratio of the change in y-values to the change in x-values is equivalent for any two points in a graph of equivalent ratios.

The horizontal distance between points is constant, and the vertical distance between points increases with each point.

The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.

Eliza intends to buy a new vehicle. She wishes to estimate the mean fuel efficiency (in miles per gallon) of all family sized SUV's currently available on the market. Eliza selects a random sample of 15 family sized SUV's and looks up their fuel efficiency on a trusted website. The results of the random sample are shown below:

27, 28, 30, 28, 28, 31, 29, 33, 28, 28, 31, 33, 41, 41, 25

What is the mean fuel efficiency rounded to the nearest whole number?

Question 1 options:

Answers

Answer:

28

Step-by-step explanation:

because if you add all the numbers together you get 433 then you have to divide 433 by the total numbers which is 15 then you get 28.

The answer is 28 because you divide 433 by 15 and get 28

Answers

Answer:

  No. Since 7^2 + 9^2 ≠ 11^2, the triangle cannot be a right triangle.

Step-by-step explanation:

You may recall that side lengths of 3, 4, 5 make a right triangle. That particular triple has several interesting characteristics. One is that it is the only (reduced) triple that is an arithmetic sequence (has a constant difference between the side lengths). Any right triangle that has sides that differ by a constant amount must be a multiple of 3, 4, 5.

Here, we have sides of length 7, 9, 11—values that differ by 2. They form an arithmetic sequence that is not a multiple of 3, 4, 5, so we know right away they cannot be sides of a right triangle.

__

If we want to use the Pythagorean relation to check, we can see if the equation is true:

  7² + 9² = 11²

  49 + 81 = 121

  130 = 121 . . . . . . Not True

Answers

Answer:

The answer should be 77, but the triangle in the question seems off. Read the explanation.

Step-by-step explanation:

To find the exterior angle in this problem, you can use the exterior angle theorem.
Interior angle + interior angle = exterior angle
25 + 52 = 77
You can double-check this answer by figuring out the third interior angle.
Since the sum of all the interior angles of a triangle should be 180, you can determine that
25 + 52 + y =180
Y= 103
or, since a straight line is always 180 degrees (Y+X=180)
25+52+(180-x)=180

X= 77
The reason why I think the question looks weird is since 77 is an acute angle, and even though it's the only answer that makes sense in this question, angle X is clearly an obtuse angle, as shown in the picture.



Solve for varible
-7y=91
a/9=-4
-1/2m=-9

Answers

1. y= -13
2. a= -36
3. m= -18

Answer:

y = -13

a = -36

m = 18

Step-by-step explanation:

-7y=91

divide both sides by -7

-7y/-7 = 91/-7

y = -13

a/9=-4

multiply both sides by 9

9(a/9) = 9(-4)

a = -36

-1/2m=-9

multiply both sides by 2

2(-1/2m) = 2(-9)

-1m = -18

divide both sides by -1

m = 18

Emily, Zeke, Harry, and Brook each conducted surveys on the number of books people have in their homes. Then, each student determined the accuracy of the following statement.
All measures of central tendency must appear as a number in the set of data collected.
Which student’s statement is CORRECT?
A.
Zeke says this is never true because all the measures of central tendency are never numbers in the set of data.

B.
Emily says this is always true because all the measures of central tendency also have to be numbers in the set of data.

C.
Harry says this is sometimes true because the mean and median may or may not be in the set of data, but the mode is always in the set of data.

D.
Brook says this is sometimes true because the mean and mode may or may not be in the set of data, but the median is always in the set of data.
