Answer:
Step-by-step explanation:
JM is a diameter. 1/2 JM is the radius. 1/2 10 = 5
The radius is 5
The above statement is true if N is the center.
The semi circle has an area of pi r^2/2 = 5^2/2 * pi = 25/2 * pi
12.5 pi
The area of the other part is
(58/360) * pi * r^2 =
0.161 * pi * 5^2
0.161 * pi * 25
4.03 * pi
Now add these two parts together.
12.5pi + 4.03= 16.53 * pi.
That's one possible answer.
Another would be 16.53 * 3.14 = 51.897
If you have choices, list them.
Answer:
The right answer is:
"If 74% of Americans still favor mandatory testing this year, then there is a 1.5% chance that poll results will show 71% or fewer with this opinion."
Step-by-step explanation:
The P-value represents the probability of getting the sample we got, given that the null hypothesis is true. For this reason, it the P-value is lower than the significance level, it means that the sample result is unlikely due to chance, but due to a false null hypothesis.
In this case, the P-value represents a probability P=0.015 of having a sample with proportion p=0.71, given that the population has a proportion π=0.74.
The right answer is:
"If 74% of Americans still favor mandatory testing this year, then there is a 1.5% chance that poll results will show 71% or fewer with this opinion."
Answer:
m= 4.5 miles
Step-by-step explanation:
Let the number of miles Evelyn can run be m and can be modeled by the equation below
m= kx
Where x Is the Minutes
When m= 3
x= 40
3= k40
k= 3/40
If x= 60
m=3/40(60)
m = (60*3)/40
m= 180/40
m= 4.5 miles
4x - 2y = 5
4x - 4x - 2y = -4x + 5
-2y = -4x + 5
-2 -2
y = 2x - 2¹/₂
y - y₁ = m(x - x₁)
y - 4 = 2(x - 3)
y - 4 = 2(x) - 2(3)
y - 4 = 2x - 6
+ 4 + 4
y = 2x - 2
