Answer:
The utilization rate with the minimum number of voters = 0.75
Step-by-step explanation:
Rate of arrival of voters = 27 voters per hour
If each voter spends 5 minutes in the voting booth,
In 1 hour, number of voters = 60/5 = 12. i.e. service rate = 12 voters per hour
Utilization rate, UR= ...............(1)
Maximum value for UR = 1. i.e UR ≤ 1
number of voters cannot take a decimal value, therefore,
The minimum number of voters = 3
Substituting number of voters into equation (1)
Answer:
gradient =
Step-by-step explanation:
calculate the gradient m using the gradient formula
m =
with (x₁, y₁ ) = (- 6, 0) and (x₂, y₂ ) = (0, 2) ← 2 points on the line
m = =

Answer:
Bag of windflower bulbs costs $8.50
Package of crocus bulbs costs $17.60
Step-by-step explanation:
Let $x be the price of one bag of windflower bulbs and $y be the price of one package of crocus bulbs.
1. Mark sold 2 bags of windflower bulbs for $2x and 5 packages of crocus bulbs for $5y. In total he earned $(2x+5y) that is $105. So,
2x+5y=105
2. Julio sold 9 bags of windflower bulbs for $9x and 5 packages of crocus bulbs for $5y. In total he earned $(9x+5y) that is $164.50. So,
9x+5y=164.50
3. You get the system of two equations:
From the first equation
Substitute it into the second equation:
9x+105-2x=164.50
7x=164.50-105
7x=59.5
x=$8.50
So,
5y=105-2·8.5
5y=105-17
5y=88
y=$17.60
