Answer:
Her final exam grade would be 11.7521 above the mean
Step-by-step explanation:
We have:
The number of students = 213
Standard deviation of total quiz = 15
Standard deviation of final exam = 17
Correlation = 0.61
0.61x17/15
= 0.6913
If the student scored 17 points above the mean of total quiz marks
17 x 0.6913
= 11.7521
Her final exam grade would be 11.7521 above the mean
Answer:
Step-by-step explanation:
Por aspa simple:
x²+x-30=0
X +6
X -5
(x+6)(x-5)=0
x+6=0
x=-6
x-5=0
x=5
espero te sirva suerte en tus estudios :D
To simplify this expression you would factor out the greatest common factor which is y^2.
9y^2 - 11xy^2 -----> Factor out y^2
y^2(9 - 11x) ----> This should be as far as you can go, meaning this is your final answer!
Hope this helps!
Answer:
Step-by-step explanation:
Answer:
A. y=0
Step-by-step explanation:
This is the equation because y=0 is just a horizontal line across the x-axis, so it'll be perpendicular with AB and go through (0,0).
y=x is wrong because it starts at the origin and goes up with positive slope of 1.
x=0 is just the y-axis, also wrong.
y=1 is just a horizontal line at one, so it's perpendicular to AB, but it doesn't go through the origin.
Hope this helps!
