Answer:
92.616%
Step-by-step explanation:
Given is the data of x and y where
x = current density (mA/cm2) and
y = rate of deposition (µm/min)
to find out whether there is linear relationship between x and y
x y
20 0.14
40 1.25
60 1.71
80 2.07
r 0.962364513
r^2 0.926145457
Since r is very near to 1, we find that there is a strong positive correlation and hence linearity can be assumed
r square the coefficient of determination is 0.9261 which is 92.616%
this is the measure which accounts for variation in x due to y and or variation in y due to x.
First you figure out that the ratio 7:4 is 1.75
Then you do this problem 28 divided by 1.75=16
And 28:16 is the same as 7:4
Now all you do is add 28+16=44
Step-by-step explanation:
In a equation of a line
y=mx+c
Let's take two points from the graph (0,1) and (4,3)
Slope=m= (3-1/4-0)= 2/4=1/2
C= 1
y=½x+1
The answer would depend on how many other numbers they are on the spinner...
1m-1.61km
50m-x
There 50 x 1.61
80.5 km
