For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.
Answer:
b=A/h
Step-by-step explanation:
To isolate b, you need to divide both sides by h. Therefore:
A=bh
b=A/h
Hope this helps!
Answer:
A. H0: μ = 6 vs. Ha: μ > 6
H0 : µ = 6 vs. Ha : µ > 6
Step-by-step explanation:
Null hypotheses state that there is no difference between a parameter and a specific value.
Alternative hypotheses states a specific difference between a parameter and a specific value.
Null hypotheses is represented as H0
Alternative hypotheses is represented as Ha.
From the question,
The claim is this "Is the mean height for all adult American males between the ages of 18 and 21 now over 6 feet?" The claimed statement represent the Alternative hypotheses.
So, the alternative hypotheses is:
Ha: μ > 6
While the null hypotheses is:
H0: μ = 6
I’d like to think ... that the answer is 18 it seems to be the same length as the line labeled 18 as well
Hope It’s Helps & Is Correct ✌
