The Factors are 1,3,29,87
Easy,
write the coordinates out in pairs:
x= hours
y= earnings
(1,10)
(2,20)
(3,30)
(4,40)
(5,50)
Now it makes it much easier to see the increase,
After 1 hour of working she has made $10
After 2 hours of working she has made $20
<span>After 3 hours of working she has made $30
</span>
And so on,
that being said it's easily seen that she is getting paid $10
Thus the unit rate is $10.
Answer:
The standard deviation is 5.29 kg.
Step-by-step explanation:
The standard deviation is the square root of the variance. Mathematically, we have that:
In this problem, we have that:
So
The standard deviation is 5.29 kg.
Variables: x and y
Coefficients: 5 and 2
Constants: 4
Exponents: 2 (if 3y is being squared)
The second one is the only equivalent equation. Simply plug in each variable in each equation. And compare!
