The median is the middle of your data when it is arranged in order.

Since you have 9 data points, the median will be the 5th value.
Your data in numerical order would be:
50 50 52 53 54 55 55 55 57

Therefore, the median is 54mm

To do this, you would need to use synthetic division.

-2 | 4 -3 10
-8 22
4 -11 32

Your reminder would be 32.

Sorry if my graph of synthetic division is a bit messy, you can only do so much on a phone!

40. In a statistics class of 30 students, there were 13 men and 17 women. Two of the men and three of the women received an A in
Harrizon [31]

Answer:

a) 56.67% probability that the student is a woman

b) 16.67% probability that the student received an A

c) 63.33% probability that the student is a woman or received an A.

d) 83.33% probability that the student did not receive an A.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

We have that:

30 students

13 men

17 women

2 men that got an A and 11 men that did not get an A.

3 women that got an A and 14 women that did not get an A.

a. Find the probability that the student is a woman.

30 students, of which 17 are women.

P = \frac{17}{30} = 0.5667

56.67% probability that the student is a woman

b. Find the probability that the student received an A.

30 students, of which 5 received an A

P = \frac{5}{30} = 0.1667

16.67% probability that the student received an A

c. Find the probability that the student is a woman or received an A.

30 students, of which 17 are women and 2 are men who received an A. So

P = \frac{19}{30} = 0.6333

63.33% probability that the student is a woman or received an A.

d. Find the probability that the student did not receive an A.

30 students, of which 25 did not receive an A.

P = \frac{25}{30} = 0.8333

83.33% probability that the student did not receive an A.

Given m ll n,<br> find the value of x and y.<br> Can someone answer this today please
Artemon [7]

Answer:

  • x = 15, y = 50

Step-by-step explanation:

m and n are parallel and cut by a transversal

<u>Finding x</u>

  • 8x + 12 + 2x + 18 = 180 (consecutive interior angles sum up to 180°)
  • 10x + 30 = 180
  • 10x = 150
  • x = 15

<u>Finding y</u>

  • 8x + 12 = 3y - 18     (vertical angles are equal)
  • 8(15) + 12 = 3y - 18
  • 132 = 3y - 18
  • 150 = 3y
  • y = 50
