X = number of cds on the rack

x + 7 = 30
x = 30 - 7
x = 23 <== so there are currently 23 cds on the rack

Solve the value for v.
NemiM [27]

Answer:

Hey mate !!

Your answer is so simple :)

<h2>V= 9°</h2>

Go through the explanation to understand.

Step-by-step explanation:

In the given question,

We see that 105° and it's adjacent angle (i.e. 8v+3° ) forms a supplementary angle. Which means the sum of 8v+3°+105° is 180°

<h3>Therefore,</h3>

According to the question

105 + 8v + 3 = 180

=  > 105 + 8v = 180 - 3

=  > 8v =  177 - 105

=  > 8v = 72

=  > v =  \frac{72}{8}

=  > v = 9

Answer the value of v is 9° .

Hope it helps you!!

The regression line has been fitted to the data points (4, 8), (2, 5), and (1, 2). the sum of the squared residuals will be:____
Inessa [10]

Based on the regression line, and the data points, the sum of squared residuals is 22.

<h3>What is the sum of squared residuals?</h3>

The squared residual can be found as:

= (y - 3 + 2x)²

For point (4 , 8)

= (8 - 3 - 2(4))²

= 9

For point (2 , 5)

= (5 - 3 - 2(2))²

= 4

For point (1, 2)

= (2 - 3 - 2(1))²

= 9

The sum of squared residuals is:

= 9 + 4 + 9

= 22

Full question is:

The regression line = 3 + 2x has been fitted to the data points (4,8), (2,5), and (1,2). The residual sum of squares will be:
