Which quadratic regression equation best fits the data set?
O = 2.608x2 +115.265z+1568.065
Oy=2.60822 - 115.265x + 1568.065
O y = 1568.065x2 + 115.265x + 2.608
O = 1568.06522 - 115.265z +2.608
Hurry please

the correct answer is

3x = x + 5

3x - x = 5

2x = 5

x = 5/2

Answer:

C) 9 heads and 9 tails

Step-by-step explanation:

if a fair sided coin is tossed, the probability of obtaining either heads or tails is 50%

If the coin is tossed 18 times, we would expect to see the same probability outcome which is 50% heads and 50% tails.

which corresponds to 9 heads and 9 tails.

Answer:

Step-by-step explanation:

Each throw is independent of any other throw. The probability of getting a head or tail is 1/2, so you should expect to flip as many heads as tails. Answer C shows that even split.

Answer:

  (b)  60°

Step-by-step explanation:

The sum of angles in a pentagon is 540°, so you have ...

  90° +90° +150° +x +150° = 540°

  x = 540° -480°

  x = 60°

Answer:

Just divide 23 by 92 using long division to get a decimal answer, then convert the decimal to a percent by moving the decimal over to the right by 2 places and adding a percent sign.

Step-by-step explanation:

23/92 = x/100

92x = 2300

x = 25

Answer: The commutative property

Step-by-step explanation: The commutative property is where an equations can be swapped and not change the answer. The following is true with that problem.

Answer:

e

Step-by-step explanation:

If you divide 36 by 12, you get 3.

For this to work, whatever the white wax is, it needs to be 3 times as more as 5.

5x3=15

Answer:

i’ve done this before

Step-by-step explanation:

E and D

for every 12ml of red wax there’s 5 ml of white wax right? so you just multiply them at the same number to see if it matches.

12 x 5 = 60

5 x 5 = 25

12 x 3 = 36

5 x 3 = 15

First move the 9 to the right side by subtracting 9 from both sides.

So we have x² + 6x ___ = 7 ___.

Notice that I created a space on each side of the equation.

The space is what we need to complete the square.

The number that goes in the spaces comes from half the coefficient of the

middle term squared, which in this case is half of 6, or 3, squared, which is 9.

So we add 9 to both sides of the equation.

Once we have completed the square, out trinomial will always factor as a binomial squared, and the number that goes inside the binomial will always be half the coefficient of the middle term of the trinomial.

So we have (x + 3)² = 16.

Now square root both sides to get x + 3 = ± 4

So x + 3 = 4 or x + 3 = -4.

Solving each equation from here, we get x = 1 or x = -7.

So our solution set is {1, -7}.

Answer:

8°

Step-by-step explanation:

5w + 1° + 7w - 7° + 90° = 180° { being linear pair }

12w = 180° - 84°

12w = 96°

w = 96° / 12

w = 8°

Hope it helps :)

Answer:

5w+1+90+7w-7=180(linear pair)

12w=180-84

w=96/12=8

Answer:

105

Step-by-step explanation:

A straight line is 180 degrees so 180-75=105

Answer:

x= 105 degrees

Step-by-step explanation:

We know that the sum of x and 75 degrees is equal to 180 degrees.

So that means that x= 180-75 or x=105 degrees

Answer:

18 ft

Step-by-step explanation:

5 years for every 3 feet

30 years

Knowing this information, we can multiply or create an equation:

Multiplication:

5 x 6 = 30 so...

3 x 6 = 18

Equation:

5/3 = 30/x

5x = 90

/5    /5

x = 18

5n+2k = 25k or 7n but u have to divide by 2

25k divided by 2 = 12.5

7n divided by 2 = 3.5

12.5 + 3.5 = 16 therefore the answer is 16
