C is the hypotenuse, which is 10.
a^2 + b^2= c^2
(6)^2 + (8)^2= (10)^2
ANSWER: B) 6^2 + 8^2= 10^2
Hope this helps! :)
Answer:
Step-by-step explanation:
The null and alternative hypothesis are usually used in hypothesis testing to present the claim being tested as give in terms of the mean or proportion :
Given that the mean score of high school students is 10 ; using a sample of 50 students, a mean of 8 was obtained ; we could want to test the claim that the mean score is less than 10.
Here; population mean, μ = 10 ; the claim is now that, μ < 10 based on what was observed about the sample.
H0 : μ = 10
H0 : μ < 10
If we wanted to test If the mean was greater than 10 ; then the sign is reversed
H0 : μ = 10
H0 : μ > 10
If we wanted to test If the score is just different from the mean score stated ; (it may be less than or greater than)
H0 : μ = 10
H0 : μ ≠ 10
Add more picture or is the one picture for all these questions
The answer should be -4,
7x2=14
2x-9=-18
14+ -18= -4
The solution is indeed accurate.
