Answer:
0.5375
Step-by-step explanation:
The point estimate of proportion of all Americans who are in favor of outlawing cheese can be computed as
p=x/n
Here. x is the number of favorable outcomes and n is sample size.
We are given that x=2150 and n=4000, So,
p=2150/4000
p=0.5375.
Thus, the point estimate of proportion of all Americans who are in favor of outlawing cheese is 0.5375.
Since the distance is 560 miles and the bus goes 268 miles per hour, the answer can be given as:
If 268=1 hour
560=?
560/268*1 hour =2(rounded to nearest ones)
Therefore it will take the train approximately 2 hours to travel between both cities.
Answer:
x=4
Step-by-step explanation:
It's a parallel line so the equation is
100+19x+4=180
19x=180-100-4
19x=76
x=76/19
x=4
Answer:
A = 157 in^2
Step-by-step explanation:
First, we need to get the radius, we can do this by dividing our given diameter by 2.
20/2 = 10
Now, we have our radius of 10 inches.
Formula for Area of a Semi Circle: (1/2)(pi(r^2)
Input values.
(1/2)(3.14(10^2)
Solve.
(1/2)(3.14(100)
(1/2)(314)
1/2(314) = 157
Finally, we have our result which is 157 inches^2.
