Answer:
Should be 606 gallons in 23 minutes
Step-by-step explanation:
If it takes 8 minutes to fill it up 226 gallons then it should take just as long from 15 to 23 as it is also 8 minutes. Meaning you add 226 to 380
16%(i used cross multiply and divide).
Answer:
h < 100
Step-by-step explanation:
isolate h by dividing both sides by 2
h < 100
For this equation I used the fact that S and U are congruent (because Line ur and rs are equal and lines UT and TS are equal. All the interior angles need to add to 360 degrees. U+R+S = 340 so T has to equal 20 degrees.
Answer: C. 461
Step-by-step explanation:
We know that the formula to find the sample size is given by :-
, where = Population standard deviation from prior study.
E = margin of error.
z* = Critical value.
As per given , we have
E= 15
Significance level :
Critical value (Two tailed)=
Now , Required sample size =
[Round to next integer]
Hence, the required sample size to be taken is 461.
Correct answer = C. 461
