Let 
be the population mean amount of garbage per bin .
Given : A sanitation supervisor is interested in testing to see if the mean amount of garbage per bin is different from 50.
i.e. 
→ Alternative
Thus , the appropriate null and alternative hypotheses :
We use the tangent for this
tan 26 1 = opposite / adjacent = h / 205 where h = height of cliff
h = 205 tan 26 1 = 100 feet
Answer:
side = 111.274........
Explanation:
area of square = side × side
means we're finding area by finding square of side.
now, we're finding side. so, we'll do the opposite of square, which means square root.
so,
side = 111.274........

Answer:
3x+5y=105
x+y=25
Step-by-step explanation:
x is the number of 3 mile runs so the total distance travelled is 3x miles. y is the number of 5 mile runs so the total distance travelled is 5y miles. Together Gavin travelled 103 miles so 3x+5y=105.
The number of 3 mile and 5 mile runs he did in total were 25 so x+y=25.
So the answer is:
3x+5y=105
x+y=25
Done.
