A] The most likely value of the correlation function for the data is -0.04, this i because the relationship between the two variables time and velocity do not how a strong linear relationship between them.
Part B:
The value of the slope between times 10 min and 20 min will be:
slope, m=(y-y1)/(x-x1)
thus taking points (10,0.2) and (20,0.8)
slope,m=(0.8-0.2)/(20-10)=0.6/10=0.06 miles/ min²
c] The relationship will be described as causation/ causality because time is partly responsible for the velocity of the toy and velocity is partly dependent on time.
It is basically 22 x 4 or the other way around 4 x 24 of which equals: 88
C
Because the graph of the line is y = 2x + 2
The graph is shaded above the line, so we want y values above the line and since it is shaded in (red and not dashed), we want the values above and on the line (aka greater than or equal to SIGN)
Hey,
So first we are told that they charg a fixed fee of 25:00 right?That means even if you didn’t send any text messages you still have to pay 25:00.
So first we have to subtract that 25:00 form 58.25 right?This means the rest of the bill is for text messages OK?
So he spent 33.25(this is the answer to the subtraction) on the text messages right?
And for every text he sent he was charged 0.35 right? So we have to divide 33.25 by 0.35 right?
And that gets us 95.
Now we can double check the answer by multiplieng 95 by 0.35 and adding 25.
So th answer is 95
Hope this helps !!
