Answer: Choice D

=========================================================

Explanation:

The angles 3,4,5,6 are all considered interior angles because they are inside or between the parallel lines.

The remaining angles 1,2,7,8 are exterior angles as they outside the parallel lines. You can think of angles 3,4,5,6 being in the river or a road, while the other angles are on the sidewalk or the shoreline.

Alternating angles are ones that are on either side of the transversal cut.

Combining the two ideas leads to alternate exterior angles being outside the parallel lines and on either side of the transversal. This applies to the following pairs:

This is why choice D is the answer.

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In this question, some of the data is missing, that's why this question  can be defined as follows:

It Includes an objective feature coefficient, its sensitivity ratio is the ratio for values on which the current ideal approach will remain optimal.

When there is Just one perfect solution(optimal solution) then the equation is:

[tex]Max \ Z = \$ 5x_1 + \$10x_2\\\\Subject\ to: \\\\8x_1 + 5x_2 \leq 80\\\\2x_1 + 1x_2 \leq 100\\\\x1, x2 \geq 0[/tex]

When there are Several perfect solutions then the equation is:

[tex]Max \ Z = \$ \ 200x_1 + \$ \ 100x_2\\\\ Subject \ to:\\\\8x_1 + 5x_2 \leq 80\\\\2x_1 + 1x_2 \leq 100\\\\x1, x2 \geq 0[/tex]

When there is also no solution, since it is unlikely then the equation is:

[tex]Max \ Z = \$40x_1 + \$10x_2 \\\\Subject \ to:\\\\8x_1 + 5x_2 \leq 80\\\\2x_1 + 1x_2 \geq 100\\\\x_1, x_2 \geq 0[/tex]

When there is no best solution since it is unbounded then the equation is:

[tex]Max \ Z = \$ 30x_1 + \$15x_2 \\\\Subject to:\\\\8x_1 + 5x_2 \geq 80\\\\2x_1 + 1x_2 \geq 100\\\\x_1, x_2 \geq 0\\[/tex]

Complete Question:

Yanay gets a lot of spam calls. An area code is defined to be a three digit number from 200-999 inclusive. In reality, many of these area codes are not in use, but for this question we'll simplify things and assume they all are.

Assuming each area code is just as likely as any other, what's the probability that the area code of two back to back spam calls are 804?

Answer:

1/6400 or 0.0000015625

Step-by-step explanation:

Given

Area Codes = 200 to 999 (inclusive)

Required

Determine the probability that back to back calls have area code 804

[First, we need to calculate the totality of area codes]

Total Area Codes = 999 - 200 + 1

Total Area Codes = 800

The probability of each code is 1/800

So, the probability of having back to back code of 804 is:

Probability = 1/800 * 1/800

Probability = (1/800)²

Probability = 1/640000

Hence, the required probability is 1/640000 or 0.0000015625

Answer:

positive 3

Step-by-step explanation:

flip it so its 10-7

Answer:

y = -2x+7

Step-by-step explanation:

equation of line formula:

[tex]y = mx + c[/tex]

m = slope, c = y-intercept

1) find the slope using the given coordinates

slope formula:

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

i) (3,1)

x1=3

y1=1

ii) (7,-7)

x2=7

y2=-7

substitute the values into the formula

[tex]m = \frac{ - 7 - 1}{7 - 3} [/tex]

[tex]m = \frac{ - 8}{4} [/tex]

[tex]m = - 2[/tex]

so now half of the equation is complete as we have the the value of m. substitute the value of m into the slope formula.

[tex]y = - 2x + c[/tex]

2) find the value of c

to find the value of c, we must substitute either coordinate into the half equation. so, i choose the coordinate (3,1). if you substitute the coordinate (7,-7) , you will get the same value of c.

(3,1)

x = 3

y = 1

[tex]y = - 2x + c[/tex]

[tex]1 = - 2(3) + c[/tex]

[tex]1 = - 6 + c[/tex]

[tex]1 + 6 = c[/tex]

[tex]c = 7[/tex]

substitute the value of c into the half equation and that is your straight line equation

[tex]y = - 2x + 7[/tex]

Answer: Sale Price = $84.99 (answer). This means the cost of the item to you is $84.99. You will pay $84.99 for a item with original price of $99.99 when discounted 15%. In this example, if you buy an item at $99.99 with 15% discount, you will pay 99.99 - 14.9985 = 84.99 dollars.

Step-by-step explanation:

principal=$1900

rate =13.6 %

Answer:

y=5x-12

Step-by-step explanation:

y=5x+3, and just replace the x and y to get the b. The slope is the same.

Answer:

8

Step-by-step explanation:

Answer:

y = -3x - 3

Step-by-step explanation:

Going from the point (0,3) to the point (1,0), we see that the rise (change in y) is -3 and the run (change in x) is 1.  Thus, the slope of the new line is

m = rise/run = -3/1 = -3.

Using the coordinates of the given point (-1, 0), we'll find the equation of this line in point-slope form:

y - 0 = m(x + 1), or y = -3(x + 1), or (in slope-intercept form)  y = -3x - 3

what is 2/3 divided by 1/6=4

Answer:

x = 60 and y=25

Step-by-step explanation:

it is equilateral triangle and  an equilateral triangle is a triangle in which all three sides have the same length. In the familiar  geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

Answer:

4833 m

Step-by-step explanation:

Given that her angle of elevation at the first recording is 47.3 at an altitude of 4900 m

We use Pythagoras Theorem to get this done

We can say that the opposite of the angle is the altitude, while the hypotenuse of the triangle, is the distance between herself and the top

Using the sine angle rule, we have

Sine 47.3 = 4900 / h

h = 4900 / sin 47.3

h = 4900 / 0.7349

h = 6668 m

This means that she was 6668 m away from the top of the mountain

She then moves 1000 m closer to the mountain top, this means that our h = 6668 - 1000

Using the same sine angle rule, we have

Sine 58.5 = o / 5668

o = 5668 * sine 58.5

o = 5668 * 0.8526

o = 4833 m

She is 4833 m above the sea level
