Answer:
- Elanor's standardized score is 1.19
- Gerald's standardized score is 0.72
- Elanor has higher score
Step-by-step explanation:
To compare Elanor's and Gerald's math scores, we need to standardize them and calculate their z-scores.
z score can be calculated using the formula
z=
where
- M is the mean score of the exam
- s is the standard deviation of the exam
Elanor's standardized score is:
z(e) = 
≈ 1.19
Gerald's standardized score is:
z(g)= 
≈ 0.72
Since z(e) > z(g), Elanor has higher score
Answer:
false
Step-by-step explanation:
7(1)-10=-3
which means -3=7(1)-10

Answer:
x = - 33
Step-by-step explanation:
Given
(x + 6) = - 18
Multiply both sides by 3 to clear the fraction
2(x + 6) = - 54 ( divide both sides by 2 )
x + 6 = - 27 ( subtract 6 from both sides )
x = - 33
For the first coordinate they have given it to you, so plug it in to get the y coordinate.
2x -3y = 4
2 * 2 - 3y = 4
4 - 3y = 4
4 - 4 - 3y = 4 - 4
-3y = 0
-3y/-3 = 0/-3
y = 0
(2, 0)
To find another set of coordinate to form a line, all you have to do is put in an x value that would make the line true.
2x -3y =4
2 * 8 - 3y = 4
16 - 3y = 4
16 - 16 -3y = 4 - 16
-3y = -12
-3y/-3 = -12/-3
y = 4
