Answer: 8 and 9 or -9 and -8
Step-by-step explanation:
Let 
be the first of the two integers. Then, since the numbers are consecutive, 
is the other integer. We then know that the sum of the squares of 
and is equal to 145. So, now we have the equation
which can be expanded and simplified to
which then gives us the quadratic equation
This can then be factored into
Which can be simplified further into
So either 
or 
. This gives us two solutions: 8 and 9 or -9 and -8.
Hope this helps! CHEERS!
F(n)=9n
f(10)=9(10)
f(10)=90
f(10)=90 means that when you work 10 hours your gross pay is $90.
Answer:
Option B
Step-by-step explanation:
Given that the regression equation using least squares for test scores and student teacher ratio is
Test Score = 557.8 + 36.42 In (Income).
Say if 1% income is increased.
Let income be 100
New income = 101
Then we have
Test score original =
Test score new income
= 
Increase = 0.362~0.36
Option B is right.
Answer:
The grade point average of the student is 49.92.
Step-by-step explanation:
A student earned grades : C, A, B, and A
Corresponding numbers of credit hours : 44, 66, 11, and 66
Assigns quality points to letter grades :
A = 4 , B = 3 , C = 2 , D = 1 , F = 0
The grade point average (GPA):
The grade point average of the student is 49.92.
Answer: LAST OPTION.
Step-by-step explanation:
The missing figure is attached.
You need to observe the circle attached and and analize the data provided in the exercise.
As you can notice in the figure, the measure of CED can be found by adding the measure of CE and the measure of ED.
Then, you can write the following equation:
You can identify in the figure that the measure of CE is:
You can also identify that the measure of ED is the following:
Knowing those measures, you can substitute them into the equation:
Finally, evaluating, you get that the measure of CED is:
