Let x be the number of girls
let 2x be the number of boys
given that There are 48 children.
<span>x+2x=48</span>x=48/3<span>x=16</span>
therefore there are 16 girls in the group...
The probability that the person is a man or heavy smoker is 621 / 1124.
<h3>What is the probability?</h3>
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0. The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.
The probability that the respondent is a man or heavy smoker can be determined by adding the probability that the respondent is a man and the probability that the respondent is a heavy smoker together.
The probability that the person is a man or heavy smoker = (number of men / total number of respondents) + (number of heavy smokers / total number of respondents)
(531 / 1124) + (90 / 1124) = 621 / 1124

A full circle is 360 degrees, so subtract your other values from that, making 178. The opposite angle is a right triangle, which is 90 degrees. So that means angle ED is 88 degrees.
Answer:
a = -2
Step-by-step explanation:
1. 14- 8 = 6
2. 6/-3 = -2
This is a linear relationship as the rate of change is constant, ie constant velocity. And the slope represents the velocity, and slope is:
m=(y2-y1)/(x2-x1)
m=(50-25)/(2-1)=25/1
m=25
So the rate of change is 25 mph
