You dived 14.28/4.2 by taking the decimal out and when you get the answer put it back
Variable A is x. Variable B is y. (x,y)
2 , 2, 4, 5, 6, 7, 8, 9
Mean is computed by adding all the numbers in the data set and dividing it by its count.
2 + 2 + 4 + 5 + 6 + 7 + 8 + 9 = 43
43 / 8 = 5.375 rounded to 5.4
Answer:
20
Step-by-step explanation:
For the sake of the problem, let's make female workers "x" and male workers "y".
x+y<40 This equation shows that the total number of workers has a max of 40.
30x+20y<1,000 This equation shows that the total cost the manager pays ($30 to each woman, $20 to each man) has a max of $1,000.
Now you can solve for x and y.
X+y<40
-y -y
X<-y+40
Substitute -y+40 in for X in the second equation
30(-y+40)+20y<1,000
-30y+1200+20y<1,000 Distribute
-10y+1,200<1,000 Combine like terms
-10y<-200 Subtract 1,200
y>20 Divide by -10; flip the sign
Since y>20, and y=male workers, you now know that the minimum
number of male workers he should send is 20
Answer:
