Answer 1

Answer: .8, -.9, -.5, .9 (estimates)

Step-by-step explanation: correlation coefficients are between -1.0 and 1.0.

    -1.0 means a perfectly negative correlation, which will be a straight line going down from left to right

    0 means no correlation, it's just random points on the graph with no sense of direction or relationship

   1.0 means a perfectly positive correlation, which will be a straight line going up from left to right

the more line-like the shape the data points make are, the further away the correlation coefficient is from 0. you can tell if it's negaitive or positive from the direction of the line.

Find f ( 6)

Answers

Answer:

so substitute x with 6

y = 4 + 36 + 1

so y or f(x) would = 41

Answer:

f(6) = 109

Step-by-step explanation:

Given polynomial:

f(x) = 2x2 + 6x + 1

To Find:

f(6)

Solution:

Here,in order to find f(6), substitute x = 6 onto the polynomial given:

f(x) = 2x^2 + 6x + 1f(6) = 2(6)^2 + 6(6) +1

Now Simplify using PEMDAS rule.

f(6) = 2(36)+36+1f(6) = 72+36+1f(6) = 108+1f(6) = 109

Hence, f(6) will be 109.

Kathy is laying stepping stones in her garden the stones are 8 inches long and she wants to create a path that is 10 feet long how many stones will she need

Answers

Answer:

15 stones

Step-by-step explanation:

1) It is easier to convert to one unit. So i chose to convert everything to inches.

1 foot = 12 inches

10 feet = 120 inches

2) we then simply divide the size of the stones to see how much we need to cover the path

120/8 = 15 stones

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

#12

The square root of a number is a whole number between 50 and 100.

Let the number be n, given:

50 < √n < 100

Square both sides:

50² < n < 100²2500 < n < 10000

The number is a perfect square between 2500 and 10000.

#13

Let the number is n:

√n > n

Square both sides:

n > n²n² - n < 0n(n - 1) < 0

Solution is:

0 < n < 1

The answer is yes, the number must be between 0 and 1.

Given that,
Lines b and c are parallel, and the m<1=4x-30 and m<5=2x+50. Find the measure of angle 1 and the measure of angle 7 .

What is the angle?

The orientation of one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

here,
From the figure,
∠1 = ∠5
4x - 30 = 2x + 50
2x = 80
x = 40
Now,
∠ 1 = 4 [40] - 30
∠1 = 130° = ∠5

∠7 = 180 - ∠5
∠7 = 180 - 130 = 40°

Thus, the required measure of the angle 1 and 7 is given as 130° and 40° respectively.

Answers

Answer:

[tex]x = \frac{-3}{2}[/tex]

Step-by-step explanation:

3(x - 4) = 11x

Expand the brackets:

3x - 12 = 11x

Subtract 3x from both sides to isolate the -12:

3x - 12 = 11x

3x - 3x - 12 = 11x - 3x

-12 = 8x

8x = -12

Divide both sides by 8:

[tex]\\\frac{8x}{8} = \frac{-12}{8}\\x = \frac{-12}{8}\\[/tex]

Simplify fraction:

[tex]x = \frac{-12}{8}[/tex]

[tex]x = \frac{-12 \div 4}{8 \div 4}\\x = \frac{-3}{2}[/tex]

If f(x) =6(9)^x then f(1/2)=?

Answers

Answer: f(1/2) = 18

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

In order to find f(1/2), we want to substitute 1/2 for x in our equation.

[tex]f(\frac{1}{2}) = 6(9)^{\frac{1}{2} }[/tex]

Then we can solve.

[tex]9^\frac{1}{2}[/tex] = 3, which means our equation is now:

[tex]f(\frac{1}{2}) = 6(3)[/tex]

6 * 3 = 18, so now we have:

[tex]f(\frac{1}{2}) = 18[/tex]
