Answer:
The correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].
Step-by-step explanation:
We know that the opposite of the opposite of a number, say 2, is the number itself.
That is:
Opposite of 2 is -2.
Then the opposite of -2 is:
- (-2) = 2
It is provided that:
Justine answered a question incorrectly and lost 7 points. Then Meagan answered correctly and got the opposite score.Assume that both Justine and Meagan started with 0 score.
Justine plays first.
If Justine answered a question incorrectly, his score would be -7.
Then Meagan plays, and answers the question correctly.
So, Meagan got the opposite score.
The opposite of -7 will be [- (-7)].
Thus, the correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].

Answer:
no
Step-by-step explanation:
What is the range of the function graphed below?
Answer: C -3< y ≤ 3
Step-by-step explanation:
Starting from the lowest point of the y coordinate to the highest point of the y coordinate. The lowest point is -3 and highest point is 3.At the y coordinate -3 there is an open circle which means we are excluding it and at the highest point 3 there is a closed circle so we will have to include that.
if 3 point A,B, and C are collinear and B is between A and C then?

Which of the following dot plots shows data that is symmetrical?
Hey there! I'm happy to help!
If something is symmetrical you can cut a line through it and it will be the same on both sides. If you have a perfect circle you can cut it in half and it will be the same on both sides, so it is symmetrical.
We see that W looks the same on both sides if you cut it in half at the 3. It is the same on both sides, so the answer is W.

Which expression gives the distance between the points (3, -8) and (3, -19)? *
1 point
Captionless Image
|3 - 3|
|-19 - (-8)|
|3 + (-19)|
|3 - (-8)|
| 3 + (-19) |
Answer:
| - 19 - (- 8) |
Step-by-step explanation:
Given that the 2 points have the same x- coordinate, then the distance between the 2 points is the difference in the y- coordinates, that is
distance = | - 19 - (- 8) | = | - 19 + 8 | = | - 11 | = 11
Or
distance = | - 8 - (- 19) | = | - 8 + 19 | = | 11 | = 11
f(x)=-4x-6 and g(x)=3x+5. Find (f o g)(-3) plzzzzzzzzzzz helpppppppp
Answer:
(f o g)(-3) = 10Step-by-step explanation:
f(x) = - 4x - 6
g(x)=3x+5
To find (f o g)(-3) we must first find
(f o g)(x)
To find (f o g)(x) substitute g(x) into f(x) that's for every x in f (x) replace it with g (x)
That's
(f o g)(x) = - 4( 3x + 5) - 6
= - 12x - 20 - 6
(f o g)(x)= - 12x - 26
Now to find (f o g)(-3) substitute the value of x that's - 3 into (f o g)(x) and solve
We have
(f o g)(-3) = - 12(-3) - 26
= 36 - 26
We have the final answer as
(f o g)(-3) = 10

Suppose a social networking site has roughly 1,000,000 users, and as each
member signs up for an account, he or she is assigned a number. Which of these would result in the largest sample size using systematic sampling?
A. Surveying every 25,000th number
B. Surveying every 25th number
C. Surveying every 250th number
D. Surveying every 2,500th number.
The option that results in the largest sample size using systematic sampling is; Surveying every 25,000th number
How to find the Sample Size?
If the numbers of people are assigned in order of 1 to 1,000,000 then the smallest sample would be obtained by conducting surveys every 25 000th numbers.
The calculation of the sample size would be made by dividing 1, 000,000 by 25000.
1,000,000/25000 = 40
Therefore, the smallest sample selected would be 40 people.
If the surveys were made every 25th numbers, then the sample size would be:

A 50 litre solution of acid and water contains 10 litres of acid. How much water must be added to make the solution 8 % acidic. Will mark brainest to whoever answers.
Answer:
Your welcome!Step-by-step explanation:
Acid present in the solution = 10 L
Required volume concentration of acid = 8/100
Let x amount of water be added to achieve the required %.
In the new solution, proportion of acid= 10/(50+x)
Therefore,
10/(50+x) = 8/100
x=75
Ans: 75 L of water must be added to the solution
