Mr. mcelroy enjoys listening to his mp3 player, which has 2,000 songs in five different genres of music. he took a sample of the number of each type of song it played on two different one-hour sessions when it was set to play a random mix. the counts are shown in the table below. which proportion would predict the number of jazz songs he has stored on his mp3 player?

Pretty sure its StartFraction 3 over 20 EndFraction = StartFraction x over 2000 EndFraction aka 3/20 = x/2000

Step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
