Answer: B 0.5 kWh per day
Step-by-step explanation:
Since the graph represents the function where electricity usage in kilowatts per hour of a clock radio varies directly with the number of days it is plugged into the wall current
The constant of variations will be the gradient ( slope ) of the graph.
Gradient = (Y2 - Y1)/(X2 - X1)
Where X1 = 2, X2 = 6, Y1 = 0.5, Y2 = 1.5
Substitute all the values into the formula
Gradient = (1.5 - 0.5)/( 6 - 4 )
Gradient = 1/2
Gradient = 0.5.
Therefore, a reasonable estimate of the constant of variation is 0.5 kWh per day

We're looking for a percentage of the people who voted for Candidate-A. So
the first thing we need to know is: How many people voted for Candidate-A ?
The number of people who voted for Candidate-A is
(1,253 men) + (1,921 women) = 3,174 people .
The question is: What percent of those people were women ?
Out of the total, 1,921 were women.
To find percent, you divide the part by the total.
1,921 / 3,174 = 0.6052 .
Changed to percent and rounded to the nearest whole one, that's<em> 61% .</em>
