Answer:
Any points on the line y=2/5 x - 6/5. See picture below.
Step-by-step explanation:
Convert the equation to slope intercept form and graph it.
2x - 5y = 6
-5y = 6 - 2x
y = -2/-5 x + 6/-5
y=2/5 x - 6/5.
Locate each of the points listed on the graph. If they are a part of the line, then they are solutions.
Answer:
x-7>0
Straight answer: x-7
Step-by-step explanation:
Assuming that the timber is X cm long and 7cm was cut off, there remaining amount is x - 7cm. In order for 7cm to be cut off, the timber must have been > 7cm long => x > 7 => x - 7 > 0

Answer:
198 is the variance for the number of defective parts made each week.
Step-by-step explanation:
We are given the following in the question:
Number of parts produced each week = 20,000
Percentage of defective parts = 1%
We have to calculate the variance for the number of defective parts made each week.
We treat defective part as a success.
P(Defective part) = 1% = 0.01
Then the number defective parts follows a binomial distribution
.
Formula for variance =
Thus, 198 is the variance for the number of defective parts made each week.
Answer:
I don't know the answer to the first one, but the second one's answer is 8.625
Step-by-step explanation:
1.5*2.5 + 1.5*2.5 + (1.5*1/5)/2 = 3.75 + 3.75 + 2.25/2 =
7.5 + 1.125 = 8.625
