Answer:

y = -1/4x - 6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Find points from the graph.

Point (-4, -5)

y-intercept (0, -6)

Step 2: Find slope m

Substitute: $m=\frac{-6+5}{0+4}$
Add: $m=\frac{-1}{4}$

Step 3: Write linear function

y = -1/4x - 6

The probability that a point is chosen at random in the square is in the blue region is 0.8.

<h3>What is Probability?</h3>

The probability helps us to know the chances of an event occurring.

$\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

As we know that the area of the shaded region is the sum of the area of triangle A and the area of triangle B. Therefore, the area of the blue shaded region is,

$\text{Area of shaded region} = (\dfrac{1}{2} \times 8 \times 8) + (\dfrac{1}{2} \times 4 \times 8)$

$= (32) + (16)\\\\= 48\rm\ in^2$

The area of the square can be written as,

$\text{Area of Square} = \rm(Side)^2 = 8^2 = 64\ in^2$

Now, the probability that a point is chosen at random in the square is in the blue region can be written as,

$\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\$

$\rm Probability = \dfrac{\text{Area of blue region}}{\text{Area of square}}\\\\Probability = \dfrac{48}{60} = 0.8$

Hence, the probability that a point is chosen at random in the square is in the blue region is 0.8.

PLZ HELP 20 POINTS FOR THE ANSWER. BTW THERE IS ANSWER CHOICE F WHICH IS NONE OF THE ABOVE

SpyIntel [72]

Answer:

F. None of the above

Step-by-step explanation:

A cone is produced by rotating the shape about line m.

The height of the cone will be 0.5 because it's perpendicular to the base.

Since the height is 0.5, the answer is not A or B.

The circular base is formed by the line split into two "1"s. Each "1" is the radius, together, the diameter of the base.

Since r = 1, the answer is not C.

Since d = 2r = 2(1) = 2, the answer is not D.

∴ The answer is none of the above, F.
