G Calculate the sample mean of x without the use of mean(), sd(), sum(), or . Hint: Recall that vectors in R are column vectors. (Although when you display them, they often look like row vectors.) You may need to create a second vector, which is allowed, and should also look into the function crossprod(). Essentially, you need to use matrix algebra to recreate the formulas above. You may use mean() to check your answer.

the answer is c

step-by-step explanation:

x + 4/7

step-by-step explanation:

use cymath

a and c

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
