Answer: ( -8,3)

Step-by-step explanation:

It's not rocket science.

An ordered pair is a composition of the x coordinate (abscissa) and the y-coordinate (ordinate).

To find the ordered pair you need to be able to identify the y and x axis.

y axis is vertical

x axis is horizontal

You want to start on the x axis and find where you think the dot is stopping at...which is -8 in the problem... once you do that move on up to the dot and move your finger to the left to see where that dot is leading you to, which is 3.

And there you have it. I hope this helps. I tried my best to explain.

Triangle MNP has vertices N(2, 2) and P(0, –2). The triangle is symmetric about the y-axis. What is the approximate measure of t

Evgesh-ka [11]

Point M of the triangle is (-2,2) to make triangle MNP as shown in the attached image

Triangle MNP has a base of 4 units and a height of 4 units. We can work out the angle x and angle y using trigonometry ratio

We use tan ratio to find both angles

$Tan (x) = \frac{opposite}{adjacent}$
$Tan(x)= \frac{4}{2}$
$Tan(x)=2$
$Tan^{-1}(2)=63.43494882$
$Angle x=63.43$

$Tan(y)= \frac{opposite}{adjacent}$
$Tan(y)= \frac{2}{4}$
$Tan^{-1}(0.5)=26.56505118$
$Angle y=26.6$

Angle MNP = Angle NMP = 63.43 degrees (this is based on the fact that the triangle is an isosceles triangle)

Angle MPN = 2×26.6 = 53.2 degrees (we multiply by 2 as angle y is only a half of angle MPN - as shown in the diagram)

The probability that aperson living in a certaincity owns a dog is estimated to be 0.3. Find the probabilitythat the tenth perso

allochka39001 [22]

The probability that the tenth person randomly interviewed in that city is the ﬁfth one to own a dog = 0.051

Given,

Consider the interview of a person is a trial.

Lets consider it success if a person owns a dog and consequently , a person without a dog will be a failure.'

Let the random variable X represent the number of persons to be interviewed to get 5 dog owner: in other words, to get 5 successors.

Probability of a success in each trial is p = 0.3. Therefore probability of a failure in each trial is q = 1 - p = 0.7 .

Because trials are independent. X has a negative binomial distribution with parameters k = 5, p = 0.3

P(X =x ) = b(x: k, p) = $[(x-1)(k-1)] p^kq^r^-^k$

where, x = k , k + 1 , k + 2......(1)

Now, Lets find the probability that the tenth person randomly interviewed in that city is the fifth one to own a dog

Using equation (1), we get:

P(X = 10) = b(10: 5, 0.3)

= [(10-1) (5 - 1)] $(0.3)^5(0.7)^1^0^-^5$

= [(9)(4)] $(0.3)^5(0.7)^1^0^-^5$

= 0.05146

Hence, The probability that the tenth person randomly interviewed in that city is the ﬁfth one to own a dog = 0.051
