What is the ordered pair for point b on the graph (-1,4) (4,-1) (5,1) (1,5)
IRINA_888 [86]

Option C: (5,1) is the ordered pair for point B

Explanation:

The graph is plotted with unit scale 1 units for both x and y axis.

We need to determine the ordered pair for point B.

<u>Ordered pair:</u>

Since, the graph is plotted with unit scale 1, the point B is 5 units away from the point (0,0)

Thus, the x - coordinate for point B is 5.

Also, the point B is 1 unit away from the point (0,0)

Thus, the y - coordinate is 1

The coordinates of point B is (5,1)

Thus, the ordered pair for point B is (5,1)

Hence, Option C is the correct answer.

Suppose you just purchased a digital music player and have put 15 tracks on it. After listening to them you decide that you like
blsea [12.9K]

Answer:

Total songs = 15

Liked songs = 3

Un liked songs = 15-3=12

Find the probability that among the first two songs played

​(a) You like both of them.

Probability that among the first two songs played you like both of them = \frac{3}{15} \times \frac{2}{14} = 0.029

​(b) You like neither of them.

Probability that among the first two songs played you like neither of them = \frac{12}{15} \times \frac{11}{14} = 0.629

​(c) You like exactly one of them.

Probability that among the first two songs played you like exactly one of them = \frac{3}{15} \times \frac{12}{14}+ \frac{12}{15} \times \frac{3}{14}= 0.343

(d) Redo​ (a)-(c) if a song can be replayed before all

​(a) You like both of them. Would this be​ unusual?

Probability that among the first two songs played you like both of them = \frac{3}{15} \times \frac{3}{15} = 0.04

​(b) You like neither of them.

Probability that among the first two songs played you like neither of them = \frac{12}{15} \times \frac{12}{15} = 0.64

​(c) You like exactly one of them.

Probability that among the first two songs played you like exactly one of them = \frac{3}{15} \times \frac{12}{15}+ \frac{12}{15} \times \frac{3}{15}= 0.32
