It is this property which makes the plane "flat". Two distinct lines intersect in at most one point, two distinct planes intersect in at most one line. If two coplanar lines do not intersect, they are parallel. Two lines which re not coplanar cannot intersect and are called "skew" lines.
Answer:
C
Step-by-step explanation:
Area of circle = 
15/2 = 7.5
7.5 = radius
Plug 7.5 into the formula:
= 176.71
Closest answer to 176.71 = 176.625
Answer would be C.
Answer:
The probability that none will have high blood pressure is 0.0281
Step-by-step explanation:
The correct question is as follows;
Twenty percent of Americans ages 25 to 74 have high blood pressure. If 16 randomly selected Americans ages 25 to 74 are selected, find each probablility. a. None will have high blood pressure
This is a binomial problem. We shall solve in that line
The probability of success is 20% or 0.2 [(Americans ages 25 to 74 have high blood pressure)] p = 0.2
The probability of failure q is thus 1-p = 1-0.2 = 0.8
The probability of none is thus;
P(X= 0) = 16C0 p^0 q^16
= 16C0 * 0.2^0 * 0.8^16 = 0.0281

Answer:
558
Step-by-step explanation:
Let p represent the student population at Edison Jr High. Then we know ...
(4/9)p = 248 . . . . . 248 students is 4/9 of the student population
p = 248(9/4) = 558 . . . multiply the equation by 9/4
558 students attend Edison Jr. High.
