Multiply (2 – 71)(-1 + 47)

Serhud [2]

(2-7i)(-1+4i)
2x-1=-2
2x4i= 8i
-7ix-1=7i
-7ix4i=-28i^2

so the answer is
-2+8i+7i+28i^2
=28i^2+15i-2

If the coefficient of determination for a data set is 0.25 and the SSE for the data set is 6, what is the SST for the data set ?

Cerrena [4.2K]

Answer: The SST for the data set is 8.

Step-by-step explanation:

Since we have given that

Coefficient of determination (R²) = 0.25

SSE for the data = 6

SST = ?

As we know the formula for coefficient of determination:

$R^2=1-\dfrac{SSE}{SST}\\\\0.25=1-\dfrac{6}{SST}\\\\0.25-1=-\dfrac{6}{SST}\\\\-0.75=-\dfrac{6}{SST}\\\\SST=\dfrac{6}{0.75}\\\\SST=8$

Hence, the SST for the data set is 8.

How do you solve<br> -2=u-93÷-3

viktelen [127]

Answer:

u=91

Step-by-step explanation:

-2=u-93÷-3

multiply both sides by 3

3(-2)=(u)3+(-93÷-3)3

-6=3u-279

add 279 to both sides

-6=3u-279

+279. +279

273=3u

divide by 3

273÷3=3u÷3

91=u
