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
Answer:
The approximate relative frequency of Managers who worked more than 40 hours will be 
.
Step-by-step explanation:
The complete question is mentioned below in the attached diagram.
From the question diagram which is attached below, it is clear that
- there are total
employees, and
- there are
are who work more than 
hours per week.
Hence, the approximate relative frequency of managers who worked more than 40 hours will be:
Which is is equal to .
Therefore, the approximate relative frequency of Managers who worked more than 40 hours will be .
To find percentage, you must divide 32 by the decimal percent. In this case, it is .64
The equation is X/P=Y, with Y being the answer.
When you plug the numbers in, you get this. 32 / .64 = Y
Since 32/ .64 is 50, the correct response is 50.
7(1/3x- 5) = 28
7/3x - 35 = 28
7/3x = 28 + 35
7/3x = 63
x = 63 * 3/7
x = 189/7 = 27 <==
