First, you'd find the mean of all the numbers by doing 10+9+16+5+10 = 50/5 = 10. Second, you'd subtract all values from the mean by doing
16 - 10 = 6
10 - 10 = 0
10 - 10 = 0
10 - 9 = 1
<span>10 - 5 = 5
Lastly, finding the mean of all 5 numbers would be, 2.4! Hope this helps!! :D</span>

Supplier B: $221.6
I hope I helped but I honestly have no idea if I did. Anyway sorry if I didn't. Good luck.

Ax^2+bx=c
REMEMBER THIS
ok
first, make sure that a is 1
done
now take 1/2 of b and square it
-18/2=-9, (-9)^2=81
add that to both sides
x²-18x+81=19+81
x²-18x+81=99
factor perfect square
(x-9)²=100
square root both sides
don't forget positive and negative root
x-9=10
x-9=-10
ad 9 to both sides
x=19
x=-1
answer is -1; 19
2nd choice is answer
Answer:
The strongest relation between the two factors is B.) -0.8
Step-by-step explanation:
The correlation coefficient typically varies from -1 to 1.
The value of -1 for the correlation coefficient denotes that the two variables are have a very strong negative correlation.
The value of +1 for the correlation coefficient denotes that the two variables are have a very strong negative correlation.
Therefore among the four options given of -0.15, -0.8, 0.38, 0.03 the strongest relation between two factors is given by -0.8 but as the '-' sign indicates the two factors are negatively correlated.
Negative correlation means that if one variable is high the other would be low.
Positive correlation means that if one variable is high then the other variable is also high and if one variable is low then the other is also low.
