Answer:
The top right quadrant
Step-by-step explanation:
This is because both the X and the Y are positive numbers meaning they are in the top right quadrant
Answer:
C) f(x)=2(25)x
For question 4: f(x)=4()^x
Step-by-step explanation: The correct answer from the choices listed above is option C. IT would be f(x) = 2(25)x that is an equivalent function to f(x) = 2(5)^2x. You can square directly 5 since it will still follow the rules for exponents.
Answer:
Test Statistic = 10
Critical Value = 9.488
Step-by-step explanation:
Given :
Grade A _ B _ C _ D _ F
_____14 _ 18 _32_ 20_16
H0 : distribution of grade is uniform
H1 : Distribution of grade is not uniform
Using the Chisquare statistic :
χ² = (observed - Expected)² / Expected
The expected value :
(14+18+32+20+16) / 5 = 20
χ² = (14-20)^2 / 20 + (18-20)^2 / 20 + (32-20)^2 / 20 + (20-20)^2 / 20 + (16-20)^2 / 20
χ² statistic = 10
The χ² critical at df = (n - 1) = 5 - 1 = 4
χ² Critical(10, 4) = 9.488
Use Pythagoras to get the height, the use it to find x:
26^2-11^2 =555
555^1/2(square root of 555)
=23.55843798 ~you need this number left as it is for a more accurate answer.
Then you do
42^2-23.55...^2(which we know is 555)
Then whatever that equals you square root that
Then you round up the answer to that to get the final answer.
I left the last part so you can do it and do some active learning, if you have more questions on this please feel free to ask, hope this helps
