Find the slope of the line that passes through the ordered pairs (-2,8) and (-9,19)

Answers

Answer 1

Answer:

slope: -11/7

Step-by-step explanation:

Slope is equal to the change in yy over the change in xx, or rise over run.

m=change in ychange in xm=change in ychange in x

The change in xx is equal to the difference in x-coordinates (also called run), and the change in yy is equal to the difference in y-coordinates (also called rise).

m=y2−y1x2−x1m=y2-y1x2-x1

Substitute in the values of xx and yy into the equation to find the slope.

m=19−(8)−9−(−2)m=19-(8)-9-(-2)

Simplify.

m=−11/7

Answer 2

Answer:

[tex]m=-1\frac{4}{7}[/tex]

Step-by-step explanation:

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\\\\\left(x_1,\:y_1\right)=\left(-2,\:8\right),\:\\\left(x_2,\:y_2\right)=\left(-9,\:19\right)\\\\m=\frac{19-8}{-9-\left(-2\right)}\\\\m=\frac{11}{-9+2}\\\\m=\frac{11}{-7} \\\\m=-\frac{11}{7}\\\\m=-1\frac{4}{7}[/tex]

What is the area of the figure?

Answers

Answer:   17.5 square yards

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

Work Shown:

base = 5 yards

height = 7 yards

The base and height are always perpendicular to one another

area of triangle = 0.5*(base)*(height)

area of triangle = 0.5*(5)*(7)

area of triangle = 17.5 square yards

The other values aren't used. They're likely thrown in as a distraction.

There are 2 value's in a game. one of them is Pancake, the other is waffle. Pancakes are worth 1.5x a waffle. I have 10 waffles, how much Pancake value do I have?

Answers

Answer:

Approximately 6.67 pancakes.

Step-by-step explanation:

We can write an equation that relates the two items.

Let P represent Pancake and let W represent Waffle.

Pancakes are worth 1.5 times a Waffle. Therefore:

[tex]W=1.5P[/tex]

To find the Pancake value for 10 Waffles, we can substitute 10 for W and solve for P. Therefore:

[tex]\begin{aligned} W&=1.5P \\ 10&=1.5P \\ 6.\overline{6}&=P \end{aligned}[/tex]

Hence, 10 Waffles equates to approximately 6.67 pancakes.

A cab company charges $4 per cab ride, plus an additional $2 per mile driven. Write an equation that shows the relationship between the distance x and the cost y. Write your answer as an equation with y first, followed by an equals sign.

Answers

Answer:

y = 2x + 4

Step-by-step explanation:

So, the cab company charges a flat fee of $4 per cab ride, meaning 4 has no variables in the equation. Now, x is the distance, and the cab company charges $2 per mile driven. Per mile driven is a distance unit, so the x goes with the 2. From that, you can get that the cost is equal to 4 dollars plus 2x (2 times the distance in miles). This is y = 2x+4.

Step-by-step explanation:

Five hundred consumers were surveyed about a new brand of snack food, Crunchicles. Their age groups and preferences are given in the table.

18–24 25–34 35–55 55 and over Total
Liked Crunchicles 39 66 10 86 201
Disliked Crunchicles 27 19 38 95 179
No Preference 24 37 35 24 120
Total 90 122 83 205 500


One consumer from the survey is selected at random. Use reduced fractions for your responses to each of the following questions.

What is the probability that the consumer is 18–24 years of age, given that they dislike Crunchicles?

Answers

Answer:

The probability that the consumer is 18 - 24 years of age, given that they dislike Crunchicles is 0.151.

Step-by-step explanation:

The age groups and preferences are given as follows:

                                     18 - 24     25 - 34       35 - 55     55 and over      Total

Liked Crunchicles           39             66              10                  86                201

Disliked Crunchicles       27              19             38                  95                179

No Preference                 24             37             35                  24                120

Total                                 90           122             83                205               500

One consumer from the survey is selected at random.

Compute the probability that the consumer is 18 - 24 years of age, given that they dislike Crunchicles as follows:

[tex]P(18-24|DC)=\frac{P(18-24\cap DC)}{P(DC)}[/tex]

                        [tex]=\frac{n(18-24\cap DC)}{n(DC)}\\\\=\frac{27}{179}\\\\=0.15084\\\\\approx 0.151[/tex]

Thus, the probability that the consumer is 18 - 24 years of age, given that they dislike Crunchicles is 0.151.

If a couple has 3 children, what is the probability of all three children being girls? Justify.

Answers

Answer:

The probability of all three children being girls will Be: 1/8

Step-by-step explanation:

The couple has 3 children.

We have to determine the probability of all three children being girls.

As we know that for each child, the probability of being a girl is ' [tex]\frac{1}{2}[/tex] ' as is the probability of being a boy is ' [tex]\frac{1}{2}[/tex] '.

so for there to be all girls, the probability will be:

P  ( all girls)  = 1/2 × 1/2 × 1/2 = 1/8      

Therefore, the probability of all three children being girls will Be: 1/8
