Answer:
8x
Step-by-step explanation:
Revenue = $2000
Labour cost = 40 x 8 = $320
Percentage = 320/2000 x 100 = 16%
Answer: 16%
Answer:
The player answer correctly 30 questions
Step-by-step explanation:
First we have to develop the information that gives us as 2 equations
x = correct answer
y = incorrect answer
z = score = 40
h = total answer = 50
2x - y = z x + y = h
2x - y = 40 x + y = 50
we clear the x of one equation and replace the value of x in the other equation
x = 50 - y
2x - y = 40
2(50 - y) - y = 40
100 - 2y - y = 40
-3y = 40 -100
y = -60/-3
y = 20
x = 50 - y
x = 50 - 20
x = 30
It is the first equation, 3x-y=-7.
It is the only equation that both sets of points satisfy as true.
There are 14 fruit to start with and 2 bananas
2/14
then there are 13 fruit and 2 pears
2/13
So the probability of the two events in a row without replacement is:
(2/14)(2/13)=4/182
2/91 ( about 2.2%)
