The solution for the problem is as follows:
((12x + 15y)/228) = 13
x + y =228
x = kentucky bluegrass
<span>y = chewings fescue
</span>
By systems of linear equations, the answers would be:
x = 152
y = 76
Therefore, there should be 152 pounds of Kentucky bluegrass to be used and 76 pounds of chewings fescue.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
Probability that 2 of the 10 chargers will be defective =0.35
Number of ways of selecting 10 chargers from 20 chargers is 20C10
20C10 = 184756
Number of ways of selecting 10 chargers from 20 = 184756
Number of ways of selecting 2 defective chargers from 5 defective chargers = 5C2
5C2 = 10
Since 2 defective chargers have been chosen, there remains 8 to choose
Number of ways of selecting 8 good chargers from 15 remaining chargers = 15C8
Number of ways of selecting 8 good chargers from 15 remaining chargers = 6435
Probability that 2 of the 10 will be defective =
(10x6435)/184756
Probability that 2 of the 10 will be defective = 64350/184756
Probability that 2 of the 10 chargers will be defective =0.35

Answer:
idk
Step-by-step explanation:
-0.8b+4.1c-(-3.2b)-0.1c
-(-3.2b)= 3.2b
4.1c-0.1c=4c
-0.8b+4c+3.2b
-0.8b+3.2b=2.4b
4c+2.4b
It would be the top one bro i know
