Using geogebra (see attached), I get roughly r = 0.98886 which rounds to r = 0.989
Answer:
0.989Side Note: The fact that r is very close to +1 means the data set has strong positive linear correlation. The points all fall very close to a line with positive slope.
Answer:
4, 6, 1
Step-by-step explanation:
We can solve this problem using a system of equations:
1) a + b + c = 11
2) 2a + 5b + 6c = 44
3) 4a - b = 10
First, we can substitute the value of b from equation #3 into equation #1:
b = 4a - 10
a + (4a - 10) + c = 11
5a - 10 + c = 11
5a + c = 21
c = 21 - 5a
Now, we can plug the values of b and c into equation #2, as b and c are represented in terms of a:
2a + 5(4a - 10) + 6(21 - 5a) = 44
2a + 20a - 50 + 126 - 30a = 44
-8a + 76 = 44
-8a = -32
a = 4
b = 4a - 10 = 4(4) - 10 = 6
c = 21 - 5a = 21 - 5(4) = 1
Part A:
10p + 12v > 3200
p > 12000
v < 15000
(imagine they have the line underneath the symbols)
Part B:
at least 14,000 cups of plain yogurt
(make sure to convert the dollars to cents so that it is accurate)
math:
10p + 12(15000) > 320000
10p > 140000
p > 14000
Answer:
y = -x + 3
Step-by-step explanation:
The equation of a line with slope equal to -1 and y-intercept equal to 3 has the form
y = mx + b. With m = -1 and b = 3, we get: y = -x + 3
Think about this problem, please. Is there any way in which you could be clearer about what you wanted to learn?
