Answer: 324 students
Step-by-step explanation:
We are given the information that 7/12 of the students like neither superhero nor space movies and this represents 189 members of the student body.
The total number of students that go to this school would be:
= 189 ÷ 7/12
= 189 × 12/7
= 27 × 12
= 324 students
Answer:
The probability that at least one of the 5 donors has Group O blood type is 0.9497.
Step-by-step explanation:
We can model this as a binomial random variable, with n=5 (the sample size) and p=0.45.
The probability that exactly k donors have Group O blood type in the sample can be written as:
We have to calculate the probability P(x≥1). In this case it easy to substract from 1 the probabitity that x is exactly 0:
Answer:
1.5%.
Step-by-step explanation:
The fractional increase is 15,000,000 / 1,000,000,000
= 15/1000
= 15 * 100 / 1000
= 1.5%
To determine the equation of the line using two points, calculate first the slope with the equation,
m = (y2 - y1)/ (x2 - x1)
In this given,
m = (7 - 1)/ (2 - 0) = 3
Use the point-slope form of the equation where,
y - y2 = m (x - x2)
y - 7 = 3 (x - 2), y = 3x + 1
Thus, the equation of the line is y = 3x + 1
