What’s green and fluffy and comes from outer space?

____________________________________________________________

1 . 2x – 4y = 8

Rewriting the standard form linear equation into slope intercept form.

-4y = -2x + 8

Dividing both sides by -4.

y = (-2/-4)x + 8/-4

y = (1/2)x - 2

The best match is A and 23.

____________________________________________________________

2. 2x + 8y = - 64

Rewriting the standard form linear equation into slope intercept form.

8y = - 2x - 64

Dividing both sides by 8.

y = (-2/8)x - 64/8

y = -1/4 x - 8

The best match is N and 19.

____________________________________________________________

3. -2x + 4y = 8

Rewriting the standard form linear equation into slope intercept form.

4y = 2x + 8

Dividing both sides by 4

y = (2/4)x + 8/4

y = 1/2 x + 2

The best match is M and 4.

____________________________________________________________

4. 3x + 5y = -15

Rewriting the standard form linear equation into slope intercept form.

5y = - 3x - 15

Dividing both sides by 5.

y = (-3/5)x - 15/5

y = -3/5 x - 3

The best match is M and 15.

____________________________________________________________

5. 12x - 3y = 3

Rewriting the standard form linear equation into slope intercept form.

-3y = -12x + 3

Dividing both sides by -3.

y = -12/-3 x + 3/-3

y = 4x - 1

The best match is L and 16.

____________________________________________________________

6. y = - 8

In this case the slope is zero. Which means the rise is zero and run can be anything greater than 1. This will make a horizontal line parallel to the y-axis at the point (0 , -8).

The best match is L and 11.

____________________________________________________________

7. x + 3y = 18

Rewriting the standard form linear equation into slope intercept form.

3y = -x + 18

y = -1/3 x + 6

The best match is T and 2.

____________________________________________________________

8. -4x + 6y = -54

Rewriting the standard form linear equation into slope intercept form.

6y = - 4x - 54

Dividing both sides by 6.

y = -4/6 x - 54/6

y = -2/3 x - 9

The best match is I and 5.

____________________________________________________________

9. 4x - y = - 8

Rewriting the standard form linear equation into slope intercept form.

-y = - 4x - 8

Dividing both sides by -1.

y = -4/-1 x - 8/-1

y = 4 x + 8

The best match is B and 22.

____________________________________________________________

10. 2x - 10y = 20

Rewriting the standard form linear equation into slope intercept form.

-10y = -2x + 20

y = -2/-10 x + 20/-10

y = 1/5 x - 2

The best match is O and 24.

____________________________________________________________

11. 6x + 9y = 9

Rewriting the standard form linear equation into slope intercept form.

9y = -6x + 9

Dividing both sides by 9.

y = -6/9 x + 9/9

y = -2/3 x + 1

The best match is E and 7.

____________________________________________________________

12. 5x - 2y = 12

Rewriting the standard form linear equation into slope intercept form.

-2y = -5x + 12

Dividing both sides by -2.

y = -5/-2 x + 12/-2

y = 5/2 x - 6

The best match is A and 8.

____________________________________________________________

13. 8x + 4y = 40

Rewriting the standard form linear equation into slope intercept form.

4y = -8x + 40

Zara is serving a fresh pie.she starts by cutting the pie in half and then cuts each half into 4 equal pieces what fraction of t

gladu [14]

Answer:

$\boxed{\frac{1}{8}}$

Step-by-step explanation:

You are starting with ½ pie. Then you cut it into four pieces.

You want to evaluate ½ ÷ 4

Step 1. Treat the integer as a fraction

$\frac{1}{2}\div{\frac{4}{1}}$

Step 2. Invert the divisor and change divide to multiply

$\frac{1}{2}\times{\frac{1}{4}}$

Step 3. Multiply numerators and denominators

$\frac{1}{2}\times{\frac{1}{4}} = \mathbf{\frac{1}{8}}\\\\\text{Each piece is } \boxed{\mathbf{\frac{1}{8}}} \text{ of a whole pie.}$

Line segment ON is perpendicular to line segment ML, and PN = 10.

Ne4ueva [31]

we know that

Triangle MOL is an isosceles triangle

because

$MO=OL=radius\ of\ circle=25\ units$

$ON=25\ units$

$ON=OP+PN\\ 25=OP+10\\ OP=25-10\\ OP=15\ units$

Find the base MP

Applying the Pythagorean Theorem in the right triangle MPO

$MO^{2} =MP^{2}+PO^{2}\\ MP^{2}=MO^{2}-PO^{2}\\ MP^{2}=25^{2}-15^{2}\\ MP^{2}=400\\ MP=20\ units$

$ML=2*MP\\ ML=2*20\\ ML=40\ units$

Find the area of triangle MOL

$A=\frac{1}{2}ML*PO\\ \\ A=\frac{1}{2}*40*15\\ \\ A=300\ unit^{2}$

therefore

the answer is

the area of triangle MOL is

$300$ square units

Answer:

Option D. statistical inference

Step-by-step explanation:

We are given the following situation in the question:

"A statistics professor asked students in a class their ages. On the basis of this information, the professor states that the average age of all the students in the university is 21 years."

This is a n example of statistical Inference.

Statistical inference is the procedure of making inference or estimating parameters of a population with the help of test statistics.

In the given situation the university students are the population and the students of a particular class are sample.

The professor with the help of sample statistic (mean age of students in class) approximated the mean age of students in the university.
