An arrow on a spinner is spun 250 times. Some of the results are shown below. The relative frequency of landing on a 4 is the sa
N76 [4]

Answer:

11/50

Step-by-step explanation:

The frequency numbers for landing on 1, 2, and 3 are:

25, 53, 62.

We add them up to get: 25 + 53 + 62 = 140

Since 250 spins were made, and 140 of them landed on 1, 2, or 3, then

250 - 140 = 110,

so 110 landed on 4 or 5.

We are told the numbers of spins landing on 4 and 5 are equal, so

110/2 = 55,

so the spinner landed 55 times on 4 and 55 times on 5.

relative frequency = 55/250 = 11/50

Which line has an equation of y=-5x+4 in slope-intercept form?
tino4ka555 [31]

You can figure the line for each pair of points, or you can try the points in the equation you have and see which are on the line.


First answer: x=1, y=-5×1 +4 = -1 . . . not 9. (1, 9) is not a point on the line


Second answer: x=2, y=-5×2 +4 = -6 . . . not -14. (2, 14) is not a point on the line


Third answer: (see the calculation for the first answer) . . . -1 ≠ 1. (1, 1) is not a point on the line


Fourth answer: (see the calculation for the second answer) We know that (2, -6) is on the given line. Checking (4, -16), we find it is as well.



The appropriate choice is the 4th answer:

... a line passing through the points (2, -6) and (4, -16)
