Luda [366]1 year ago

5 0

Answer:

28, 28, 34, 34

Step-by-step explanation:

8x - (6 + y)

8(5) - (6 + 6)

40-12

w ¾ + x²

4(¾) + 5²

3 + 25

y² - 0.5w

6² - 0.5(4)

36 - 2

w / 4 + 3(x + y)

4 / 4 + 3(5 + 6)

1 + 3(11)

Complete the tables of values.

zlopas [31]

<u>Answer with Step-by-step explanation:</u>

We are given two tables and we are to complete the missing values.

For table one, we are to substitute the given values of x in the term $4^{-x}$ :

when x = 0, $4^{-0} = 1$

when x = 2, $4^{-2} = \frac{1}{16}$

when x = 4, $4^{-4} = \frac{1}{256}$

For table two, we are to substitute the given values of x in the term $(\frac{2}{3} )^x$ :

when x = 0, $(\frac{2}{3} )^0 = 1$

when x = 2, $(\frac{2}{3} )^2 = \frac{4}{9}$

when x = 4, $(\frac{2}{3} )^4 = \frac{16}{81}$

Given that the sum of squares for error is 60 and the sum of squares for regression is 140, then the coefficient of determinatio

Anastasy [175]

Answer:

Step-by-step explanation:

The coefficient of determination which is also known as the R² value is expressed as shown;

$R^{2} = \frac{sum\ of \ squares \ of \ regression}{sum\ of \ squares \ of total}$

Sum of square of total (SST)= sum of square of error (SSE )+ sum of square of regression (SSR)

Given SSE = 60 and SSR = 140

SST = 60 + 140

SST = 200

Since R² = SSR/SST

R² = 140/200

R² = 0.7

Hence, the coefficient of determination is 0.7. Note that the coefficient of determination always lies between 0 and 1.
