Answer:
n = 200
p = 0.33.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
In this problem we have that:

Answer:
73°
Step-by-step explanation:
the measure of two complementary angles add up to 90
so We need to solve this equation to get the measure of its complementary angle :
x + 17 = 90
then
x = 90 - 17
= 73
Answer:
No
Step-by-step explanation:
y = 2x -1
Substitute the point into the equation
4 = 2(3) -1
4 = 6-1
4 =5
This is not a true statement so the point is not on the line
