Answer:

slope = -7/3

Step-by-step explanation:

slope formula: (y2-y1)/(x2-x1)

We need to implement the points into this formula

y2 = 3

y1 = -4

x2 = -1

x1 = 2

(3-(-4)) divided by (-1-2) = 7/-3 = -7/3

Describe a sequence of transformations that can be performed to polygon ABCDE to prove that it is similar to polygon FGHIJ

maxonik [38]

Answer:

answer below

Step-by-step explanation:

ABCDE go through dilation over center (6 , -2) with factor of 1/2 to FGHIJ

AB // FG slope: -2 , √20:√5 = 2: 1

BC // GH // X axis 8:4 = 2:1

CD // HI, slope= 1 , √8:√2 = 2:1

DE // IJ // x axis, 4:2 = 2:1

EA // JF // y axis, 2:1

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Ski

Event B: Snowboard.

28 out of 120 students ski:

This means that $P(A) = \frac{28}{120} = 0.2333$

16 out of 120 do both:

This means that $P(A \cap B) = \frac{16}{120} = 0.1333$

P ( snowboard I ski)

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.1333}{0.2333} = 0.5714$

P ( snowboard I ski) = 0.5714

How do i identify the slope in a math question?

Thepotemich [5.8K]

Answer:

y=mx+b is the equation for a line, x and y being coordinates, m as your slope and b as your y intercept. Slope is rise over run.
