Answer:
A correlation coefficient of +1 or -1 will indicate a direct linear model is the most appropriate but 0.94 shows that a very good direct correlation exists between the length of an aspen leaf and its surface area.
Step-by-step explanation:
this is because a values of r lying between +1 and −1, where +1 indicates perfect direct correlation,−1 indicates perfect inverse correlation and 0 indicates that no correlation exists.
Between these values, the smaller the value of r, the less is the amount of correlation which exists. Generally, values of r in the ranges 0.7 to 1 and −0.7 to −1 show that a fair amount of correlation exists.
A correlation coefficient of 0.94 shows that a very good direct correlation exists between the length of an aspen leaf and its surface area but not necessarily indicate a linear model is the appropriate .
Answer:
12°
Step-by-step explanation:
Sum of interior angles of the triangle is 180°:
m∠A + m∠B + m∠C = 180°
3x + 28° + 5x + 52° + 2x - 10° = 180°
10x + 70° = 180°
10x = 110°
x = 11°
Find the measure of angle C:
m∠C = 2x - 10° = 2(11°) - 10° = 22° - 10° = 12°
Use rounding to get -6(0.2), and then multiply.
Use compatible numbers, such as -6(0.5), and then multiply.
Use front-end estimation to get -6(0.2), and then multiply.
Estimate -6.1(0.22)
Answer:
Use rounding to get -6(0.2), and then multiply.
Use front-end estimation to get -6(0.2), and then multiply.
Round the factors to the nearest whole number, and then multiply.
Step-by-step explanation:
Actual answer:
-6.1(0.22) = -1.342
Estimate answer:
-6 (.2) = 1.2
Answer:

Step-by-step explanation:
Answer:
Tennessee
Step-by-step explanation:
First, let's find out how much tax he paid...
$695.49-$649.99=$45.50
We can use this to set up an equation...
x%(649.99)=45.50
We can convert x% to x/100 since any percentage is just that number over one hundred...
Multiply 100 to both sides
Divide both sides by 649.99
This is closest to 7 (our answers is not exact since you can only have two decimal places in money), therefore he lives in D. Tennessee
