Answer:
6
Step-by-step explanation:
So to find how much sheep there were on each acre, you divide.
250/40
You do this because you are splitting the 250 sheep into 40 acres.
250/40 = 6.25
There cannot be .25 of a sheep, and since it says on average the answer does not need to be exact. So you would round it off to 6 as your answer.
Answer:
12 inches
Step-by-step explanation:
The formula for a trapezoid is
A = 1/2(a +b)h
The formula to find the height =
h = 2A/a + b
A= 216 in²
a =14 in
b = 22 in
Hence,
h = 2 × 216/14 + 22
h = 12 inches
The height of the trapezoid = 12 inches
Answer:
15(5)+3=78
21(5)+4=109
78+109=187
Step-by-step explanation:
The value of co-efficient of determination is 0.241.
<h3>What is the relationship between linear co-relation co-efficient and co-efficient of determination ?</h3>
The co-efficient of determination R² is similar to the linear correlation co-efficient.
We can think of co-relation of determination as a percentage. It gives us the data for how much percentage of data will fall within the linear co-relation.The higher the percentage the more data falls within.If the coefficient is 0.5 then 50% of data falls within the linear co-relation.
According to the given question
Linear correlation coefficient is -0.491
∴ Co-efficient of determination is (-.491)² which is equal to 0.241.
