Answer:
0.5944 = 59.44% probability that the team has at least 2 grade 11 students
Step-by-step explanation:
The students are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x successes is given by the following formula:
In which:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
We have that:
6 + 8 = 14 students, which means that
6 grade 11 students means that
Teams of 4 members means that
What is the probability that the team has at least 2 grade 11 students?
This is:
In which
So
Then
0.5944 = 59.44% probability that the team has at least 2 grade 11 students
Answer:
The answer to your question is:
Step-by-step explanation:
If the line is rotated, we get the perpendicular of the initial line.
See the attachment, the blue line is the original and the red one is the new line.
Process
new slope = 2/5
Point ( 0, 4)
(y - y1) = m (x - x1)
( y - 4) = 2/5 (x - 0)
y - 4 = 2/5 x
y = 2/5 x + 4 New line
