Answer:

3x - 11

Step-by-step explanation:

(x-4)+(2x-7)

We can remove the parenthesis because we are adding and not multiplying.

x - 4 + 2x - 7 Combine like terms

x + 2x - 4 - 7

3x - 4 + - 7

3x - 11

Andre45 [30]

To solve, isolate the variable (x)
Steps:
a) simplify 4/6, the smaller the number the better when it comes to fractions:
2/3x - 34 =32
b) add 34 to both sides:
2/3x = 66
c) multiply by 3 to get it out of the denominator:
2x = 198

A multiple regression model involves 5 independent variables and a sample of 10 data points. If we want to test the validity of

Ber [7]

Answer:

The critical value is 6.26.

Step-by-step explanation:

It is provided that there are 5 independent variables involved in a multiple regression model and the sample consist of 10 data points.

The critical value of F to test the significance of the model is:

$\text{Critical Value}=F_{\alpha, (k, n-k-1)}$

Here,

k = number of independent variables

n = number of observations.

Then the critical value is:

$\text{Critical Value}=F_{\alpha, (k, n-k-1)}$

$=F_{\alpha, (5, 10-5-1)}\\=F_{0.05,(5, 4)}\\=6.2561\\\approx 6.26$

*Use a F-table.

Thus, the critical value is 6.26.
