Answer:
19,600.
Step-by-step explanation:
Combination as the order of applicants des not matter.
Number of ways = 50C3
= (50*49*48)/ (3*2*1)
= 50*49*8
= 19,600.
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:
AOB = 55°
BOC = 87°
COD = 130°
AOD = 88°
Step-by-step explanation:
AOB = a°
= 55°
BOC = b°
= 87°
COD = c°
= 130°
AOD = 360°-AOB-BOC-COD
= 360°- a° - b° - c°
= 360° - 55° - 87° - 130°
= 88°

Answer:
48 people
Step-by-step explanation:
1. 4/50 = x/600 do 4x600 and 50 times x
2.50x=2400
3. divide both sides by 50 to get a result of x=48.
