A poll shows that 50% of students play sports. A random sample of 20 students showed that 70% of them play sports.

A number generator was used to simulate 20 samples from a population in which 50% of students play sports. The results are shown in the dot plot.

What is the chance of getting a sample proportion of 70% or greater?

0.2

0.3

0.4

0.6

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

x=6 and x=3

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
