Given are:
250 adults and 180 parents
so we can solve the number of not parents
not parents = 250 - 180
not parents = 70
then we can number of people of votes for no
no not parents = 70 - 40 = 30
no parents = 180 - 150 = 30
yes no
parents 150 30
not parents 40 30
Answer:
y= 2/5x+4/5
Step-by-step explanation:
identify two points on line m then find it's gradient.
using the gradient of line m find the gradient of the perpendicular line
then use points (3,2) and (x,y) to find it's equation.
Answer:
-2
Step-by-step explanation:
4/5 = 0.8 which would be 80%
Answer:
0.8
Step-by-step explanation:
The question here says that In a class of 30 students, 18 are men, 6 are earning a B, and no men are earning a B. If a student is randomly selected from the class, find the probability that the student is a man or earning a B.
Since the question says that 18 out of 30 students are men,6 out of the remaining people earn a "B" and non of the 18 men earn a "B".
The probability of picking a man or a person that earns a "B" is
18/30 (since there are 18 men out of the 30 students)
And 6/30(since there are 6 people that earn a "b")
The probability of picking a man or a "b" earner is
18/30 + 6/30
= 24/30 or 0.8
