Answer:
0.783
Step-by-step explanation:
To find first r and then r square for the data
correlation coefficient of x and y = Cov (x,y)/std dev x * std dev Y
Cov (x,y) = E(xy) -E(x)E(y)
Hence calculations would be as follows:
x y xy
1 2 2
2 10 20
5 5 25
7 18 126
10 25 250
Mean 5 12 84.6
Cov E(xy)-E(x)E(y) 24.6
r 0.884640297
r^2 0.782588454
so answre is 0.783 after rounding off.
Answer:
I think it would become 20 because if you were to half seven, it would be about 3, and if 7 m/s2 makes around 40N, half that and you would get 20.

Answer:
<h2>
</h2>
Step-by-step explanation:
First of all using the addition property add 4x to both sides
That's
Next using the subtraction property subtract 18 from both sides to make 34x stand alone
We have
<u>Divide both sides by 34</u>
That's
We have the final answer as
