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.

Mars2501 [29]

Answer:

Step-by-step explanation:

Growth rate is 3%

Current pop is 75000 taking 2000 as current year.

Time difference between 2030 and 2000 = 30 years

Growth rate in a year = 100%+3% ×75000 = 77250 people

Population in 2030= 77250×30 = 2,317,500 people

Gotta be correct.
