Should be $1900.
I divided 36.8% by 18.4 to get a whole number. (2%)
Same goes for $700. Divided that by 18.4. ($38)
This means that $38 is 2% of Sally's yearly salary
2% times 50 is 100% and $38 times 50 is $1900
The area of the wall including the windows is 152ft
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
1 ton is 2,000 lbs
9 x 2,000 = 18,000
So, 18,000 is equal to 9 tons.
Hope this helps. :)
