Answers

So you take the lowest and highest values of each set and subtract the lowest value from the highest one (to calculate the range).

A. Range is 17
B. Range is 22
C. Range is 23
D. Range is 24

Therefore D’s set of data has a range with the greatest difference

Yes. Since 7^2+9^2=11^2, the triangle must be a right triangle.

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

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.

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

Answers

Answer:

The difference between the two is that in a dependent event an action will affect the ultimate outcome, but in an independent event an action won't affect the ultimate outcome. A way to tell is if the total number of the "item" at hand will be affected by the action the question is saying. In the case of the example given, that is a dependent event because the total of marbles you started with is changed due to you not replacing the one you first took. Therefore the probability is now different.
