The sum of the residuals should always be 0 because the predicted values should be that close to the actual values.
True or false

Answer: The answer is 9/30.

Step-by-step explanation:

The total of the number of DVDs is 30. The number of western DVDs is 9. This forms a proportion for probability which is 9/30.

I think it's 462.99, rounded it's 463

Answer:

0.972x

Step-by-step explanation:

x - 0.1x + 0.08(0.9x)

Converting percentages to decimals has you divide the percentage by 100.

So our first equation is full price minus a tenth of that price, leaves you with nine tenths, right? Then we multiply that nine tenths by 8 percent, which is 8 hundredths.

0.9x + 0.072x = 0.972x

Answer:

150 workers are at the company

Step-by-step explanation:

If 20% of the workers is equal to 30 workers than in order to find 100% of the worker you need to multiply the percentage with a number that makes it 100% and then multiply that number to the 30 workers so

20% * 5 = 100%

30 * 5 = 150

so 100% of the workers is equal to 150 workers

Answer:

t=100-s

Step-by-step explanation:

Since we know T as the total amount, we need to figure out how much was spent from the $100 Julie has. She can't gain more money magically so you have to take away from the 100. The amount taken away is the S (a.k.a- how much was SPENT). After putting that together, you get t=100-s.

Step-by-step explanation:

36.77 Times (x) 0.2 (percentage)

7.354

round

$7.35

EX: If it was on 20% off and an item was 36.77 then you would also mutliply it and then subtract 7.35 from 36.77

Answer:

[tex] \rm Numbers = 4 \ and \ -3.[/tex]

Step-by-step explanation:

Given :-

And we need to find out the numbers. So let us take ,

According to first condition :-

[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]

Hence the numbers are 4 and -3

Step-by-step explanation:

[tex]integers \: = x \: and \: y \\ then \: x \times y = - 12 ....(1)\\ x + y = 1.....(2) \\ x = 1 - y.....(3) \\ put \: (3 )\: in \: (1) \\ then \: (1 - y) \times y = - 12 \\ y - {y}^{2} + 12 = 0 \\ {y}^{2} - y - 12 = 0 \\ factorise \\ {y}^{2} - 4y + 3y - 12 = 0 \\ y( y - 4) + 3(y - 4) \\ (y - 4)(y + 3) \\ y = 4 \: and \: - 3 \\ thank \: you[/tex]

Answer:

[tex]\sqrt{65}[/tex]

Step-by-step explanation:

d = √(5+2)²+(0+4)²

d = √7² + 4²

d = √49+16

d = √65

Answer:

square root of 65

Step-by-step explanation:

So remember, the pythagreons theorm is A^2+B^2=C^2.

A and B are the side lengths, and C is the long, sloped line.

Lets count the side lengths, and plug them into the formula.

Line CB is 4, and counting AB, its 7. So lets plug them in:

4^2+7^2=C^2

Square the values(except for the missing one):

16+49=C^2

=

65=c^2

Now, we need to get C on its own.

To do this, we must get the square root of both sides:

[tex]\sqrt{65} =\sqrt{C^2}[/tex]

=

[tex]\sqrt{65} =C[/tex]

So C equals the square root of 65!

This is C, the third answer down(the square root of 65).

Hope this helps! :)
