Answer:
Step-by-step explanation:
Area of the Pond A= 
The increase in the area of the pond as it moves outward is: 
Since the area of the circle formed increases at the rate of 100 square feet per minute.
= 100 Square feet per minute
When the radius, r = 5 feet, we want to determine the rate at which the radius is changing, 
.
Answer:
H0: p1-p2=0
Ha: p1-p2≠0
This hypotheses can be written as
H0: p1=p2
Ha: p1 ≠p2
Step-by-step explanation:
Here the claim is if these data provide strong evidence the rate of sleep deprivation is different for the two states which will be formulated as alternate hypothesis .
Ha: p1-p2≠0
The null hypothesis is
H0: p1-p2=0 i.e these data do not provide strong evidence the rate of sleep deprivation is different for the two states.
where p1 = as population 1 of California
p2= as population 2 of Oregon
This hypotheses can be written as
H0: p1=p2
Ha: p1 ≠p2
which will also give the same results as above and a two tailed test will be performed for both hypotheses.
Answer:
85 tickets where sold
Step-by-step explanation:
Which equals 85 tickets
To find the distance between two coordinate points, we can use the distance formula as shown below.
distance = √[(x₁ - x₂)² + (y₁ - y₂)²]
where (x₁, y₁) and (x₂, y₂) are the coordinates we are comparing. So for M(6, 16) and Z(1, 14), we have
distance = √[(6 - 1)² + (16 - 14)²] = √(9 + 4) = 3.6.
Therefore, the distance M and Z is equal to 3.6 units.
