Let p be the percentage of students enrolled in an introductory Chemistry class dropped before the midterm. Then null and alternative hypotheses are:
: p=10%
: p>10%
The alternative hypothesis states that the parameter is greater than the hypothesized value.

Answer:
Solution given:
y=25 [base side of isosceles triangle]
sin 45=opposite/hypotenuse
sin45=25/x
x=25/sin45
x=25√2
Answer:
All the points on (x - 2)² + (y - 5)² = 100
Step-by-step explanation:
It should be the circle with its center on point (2,5) and radius is 10.
(h , k) : center of circle (2,5) h = 2 k = 5
r: radius r = 10
Circle: (x - h)² + (y - k)² = r²
(x - 2)² + (y - 5)² = 100
Answer:
The runners drank 661 bottles of water.
Step-by-step explanation:
Subtract 661 from 750, and you are left with 89.
