Find the slope of a ski run that descends 15 feet for every horizontal change 24 feets
Diano4ka-milaya [45]

Answer: 5/8


Step-by-step explanation:


Slope is determined by dividing the amount of vertical movement by the amount of horizontal movement and then simplifying the answer. In this case it is 15/24. To simplify you need to find the least common denominator (LCD), which is 3, and divide both numbers by it. 15/3=5 and 24/3=8, so the answer is 5/8.

Find the distance between each pair of points <br><br> (7 1/2, 3 1/4) and (7 1/2, 9 1/2)
Alexeev081 [22]

Answer:

d=13

Step-by-step explanation:

D = √(x2 - x1)2 + (y2 - y1)2

D = √(-6 - (-8))2 + (1 - 4)2

D = √(-6 + 8)2 + (-3)2

D = √(2)2 + (-3)2

D = √4 + 9

D = √13

During a single day at radio station WMZH, the probability that a particular song is played is 1/5. What is the probability that
Lilit [14]

Answer:

the probability that the song should be played on accurately  3 days out of 5 days is 0.051

Step-by-step explanation:

Given that

The probability that a particular song is played is 1 by 5

We need to find out the probability that the song should be played on accurately  3 days out of 5 days

So,

P(x = 3) = \frac{5!}{3! (5 - 3)!} (\frac{1}{5})^3(1 - \frac{1}{5})^{5-3}

= 0.051

Hence, the probability that the song should be played on accurately  3 days out of 5 days is 0.051

The same is considered
