Answer:
41
Step-by-step explanation:
We know that complex numbers are a combination of real and imaginary numbers
Real part is x and imaginary part y is multiplied by i, square root of -1
Modulus of x+iy = ![\sqrt{x^2+y^2}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E2%2By%5E2%7D)
Here instead of x and y are given 9 and 40
i.e. 9+40i
Hence to find modulus we square the coefficients add them and then find square root
|9+49i| =![\sqrt{9^2+40^2} =\sqrt{1681}](https://tex.z-dn.net/?f=%5Csqrt%7B9%5E2%2B40%5E2%7D%20%3D%5Csqrt%7B1681%7D)
By long division method we find that
|9+40i| =41
Answer:
<u>a. two or more samples are equal.</u>
<u>Step-by-step explanation:</u>
ANOVA (Analysis of Variance) is a statistical procedure that could be used to compare two or more population means are equal.
Remember, the means referred to here is the expected value or average value of a set of numbers, which is calculated by summing the values in a given set divided by the number of values. Also, put simply, the analysis of variance is a measure of how much differences exist out a data set.
