Which Regression Equation Best Fits These Data ?

Answers

Answer 1

Answer:

C. [tex]y = -0.30\cdot x^{2}-0.48\cdot x+15.83[/tex]

Step-by-step explanation:

The best fit curve for the given set of points is the quadratic form, which is defined by:

[tex]y = A\cdot x^{2}+B\cdot x + C[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]A[/tex], [tex]B[/tex], [tex]C[/tex] - Coefficient.

The coefficient associated with the second-power component determines whether vertex is an absolute maximum or not. The vertex is an absolute maximum if and only if [tex]A < 0[/tex], otherwise it is an absolute minimum. From image we notice that resulting fit curve will have an absolute maximum, then [tex]A < 0[/tex]. Hence, the correct answer is C.

Answer:

Both Question (bottom right corner)

Step-by-step explanation:

Question 2 is obviously a variable because the amount of goals you can score in a game varies, one game it could be 10 then next it could be 5, But for question 1 the amount of work hours she puts in, (assuming she choses when to work and when not to) is also a variable because the amount she works varies from day to day.

Both these examples how data that varies from day to day.

Subtract 5 from 8 to get 3.

3×2.3−8=2

Multiply 3 and 2.3 to get 6.9.

6.9−8=2

What is the value of x in the equation below?
3(12x-24) = 16
A) 2
B) 6
C) 8
D) 10



ANSWER: B) 6

Answers

Answer:

3(12x - 24) = 16 (use the distributive property)

36x - 72 = 16  (add 72 to both sides to get the x-term alone)

36x = 88 (divide both sides by 36 to isolate x)

x = 2.4 (the four is repeating. that's the exact answer.)

I would say the answer is A because 2.4 is close to 2 than any of the other answers.

y=11
is the answer to your question! <3

Answer:

y is 11

Step-by-step explanation:

-7y = -77

Divide both sides by -7

-7y/-7 = -77/-7

Since it's -77/-7, a negative divided by a negative gives us a positive output.

Y=11 is our final answer.

Find g(x), where g(x) is the translation 6 units up of f(x)=x2. Write your answer in the form a(x–h)2+k, where a, h, and k are integers.

Answers

Answer:

g(x) = x²+6

Step-by-step explanation:

g(x) = f(x)+6 = x²+6

If f(x) = -2 and g(x) = 2x² + x-3, find (f +9)(x).

Answers

Answer:

(f + g)(x) = 2x² + x - 5

Step-by-step explanation:

Given

[tex]f(x) = -2[/tex]

[tex]g\left(x\right)\:=\:2x^2+\:x-3[/tex]

To determine

(f + 9)(x) = ?

Using the formula

(f + g)(x) = f(x) + g(x)

substituting f(x) = -2 and g(x) = 2x² + x - 3

             = -2 + 2x² + x - 3

             = 2x² + x - 5

Therefore, we conclude that:

(f + g)(x) = 2x² + x - 5

Mrs kin picked some tomatoes from her garden. She use 5/9 of her tomatoes to make pasta sauce. Then she used 5/8 of the remainder to make a salad and saved the rest for the next day. What fraction of the tomatoes did mr kin saved

Answers

Answer:

1/6 of the tomatoes

Step-by-step explanation:

So first, after she uses 5/9 she has 1 - 5/9 = 4/9 of her tomatoes left. Then, she uses 5/8 of that 4/9 to make a salad, so she used 5/8 * 4/9 = 5/18 of her tomatoes overall.  That means that she has 4/9 - 5/18 = 8/18 - 5/18 = 3/18 = 1/6 of her tomatoes saved.
