Answer:
Step-by-step explanation:
5% of 3,000 is 150
Start by finding the first number on the Y axis,
then find the next number on the x axis, you can move up OR down if you have to
Make sure if your number is a - for instance, (-5, 1) you plot it on the negative 5 one, not the positive five.
Answer:-2/3
Step-by-step explanation:the problem is asking for the slope of (0,2) and(3,0). The formula for this problem is y2-y1 over x2-x1. And if your writing this formula down write it like a fraction with y on top and x on bottom. (x,y) (x2,y2). You take the 0 from the second set and the 2 from the first set and subtract them to get -2. Then you take the 3 from the sea d set and the 0 from the first set and you subtract them to get 3. That’s how you get the answer of -2/3.
Answer:
a) The third quartile Q₃ = 56.45
b) Variance 
Step-by-step explanation:
Given that :
= 30.8
Median 
= 48.5
Mean = 42
a) The mean is less than median; thus the expression showing the coefficient of skewness is given by the formula :
Divide both sides by 1.38
b) The objective here is to determine the approximate value of the variance;
Using the relation
Variance = 
For this you would do 4000 x 0.2 which equals 800.
800 acres were not plowed.
