What is the slope of the line NP

Luba_88 [7]

Answer:

The slope of NP is $\frac{-5}{7}$ ⇒ B

Step-by-step explanation:

In any square, every two opposite sides are parallel and every two consecutive sides are perpendicular

Parallel lines have the same slope

The product of the slopes of the perpendicular lines is -1, which means if the slope of one m, then the slope of the other is $\frac{-1}{m}$ (reciprocal m and change its sign)

The rule of the slope of the line which passes through the points (x1, y1) and (x2, y2) is m = $\frac{y2-y1}{x2-x1}$

In square MNPR

∵ MN and NP are adjacent sides

∴ MN ⊥ NP

∵ M = (3, 8) and N = (-2, 1)

∴ x1 = 3 and y1 = 8

∴ x2 = -2 and y2 = 1

→ Use the rule of the slope above to find the slope of MN

∴ m(MN) = $\frac{1-8}{-2-3}$

∴ m(MN) = $\frac{-7}{-5}$

∴ m(MN) = $\frac{7}{5}$

∵ MN ⊥ NP

∴ The product of their slopes = -1

→ Reciprocal the slope of MN and change its sign

∴ m(NP) = $\frac{-5}{7}$

∴ The slope of NP is $\frac{-5}{7}$

A spinner is divided into five sections numbered 1 through 5. Juana records the number the spinner lands on for each of 50 spins

Jet001 [13]

The distribution of the probability of the given data is a Positive Skewed Probability distribution.

Given to us

A spinner is divided into five sections numbered 1 through 5. Juana records the number the spinner lands on for each of the 50 spins. She computes and graphs the relative frequencies for each number

<h3>What is a Probability distribution?</h3>

It is a type of distribution in which the distribution has a constant probability, therefore, the probability of each event occurring is equal.

<h3>What is symmetric distribution?</h3>

Symmetric distribution is the type of distribution where the left side of the distribution and the right side of the distribution are mirror images to each other, therefore, they are symmetrical.

<h3>What is Negatively Skewed Probability distribution?</h3>

Negatively Skewed Probability distribution is a type of distribution of the probability where the right side(tail) of the distribution is more concentrated than the right side.

<h3>What is Positive Skewed Probability distribution?</h3>

Positive Skewed Probability distribution is a type of distribution of the probability where the left side of the distribution is more concentrated than the right side.

<h3>Which of the following describes the probability distribution of the given data?</h3>

Since in the given graph probability of every number occurring from 2 to 5 is equal to 0.12(12%), while the probability of number 1 occurring is 0.5(50%).

Thus, the distribution of the probability is towards the right end of the graph.

Hence, the distribution of the probability of the given data is a Positive Skewed Probability distribution.
