Out of 50 people surveyed, 42 respond ‘yes’ to the survey question. What is the probability of a ‘yes’ response? Write your answer as a decimal.

Step-by-step explanation:

Given

Total no. of observation = 50

Given, No. of observations that told yes = 42

Therefore,

Probability of getting response as yes

In decimal form ,

= 0.84 (Ans)

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
