Answer:
1 mile = 160 934.4 centimeters
For this case we have that by definition, if we draw the diagonal of a square two rectangular triangles are formed. If the diagonal measures "x", then the Pythagorean theorem is fulfilled:
Where:
l: It's the side of the square.
We know that the area of a square is given by:
So, the area is:
Answer:
12 pages
Each side count as a page
21+15=36 36/3=12

Answer with explanation</u>

Let be the average estimated calorie content in the population.
As per given , we have
, since the alternative hypothesis is right -tailed , so the test is a right tailed test.
Sample size : n= 58
Sample mean :
sample standard deviation : s= 86
Population standard deviation is unknown , so we use t-test.
Test statistic:
Critical value at significance level 0.001 and degree of freedom 57 (∵ df=n-1 ) :
Decision : Test statistic value is greater than the critical value at significance level 0.001, so we reject the null hypothesis .
Conclusion : We have sufficient evidence to support the claim that the true average estimated calorie content in the population sampled exceeds the actual content.
You could do :
Johnny was financing a limited editions Xbox One S. The price was $420 and he put down 40%. How much is left to be financed?
dp=420(40/100)=16800/100=168
then you would subtract 420-168 which would give you 252
;) good luck !!
