Answer:

rectangles are similar figures, thus if scaled copies of each other then the ratios of corresponding sides must be equal

compare ratios of lengths and widths

rectangles A and B

k = = ← ratio of lengths

k = = ← ratio of widths

scale factors are equivalent, hence rectangle A is a scaled copy of B

rectangles C and B

k = = ← ratio of lengths

k = = ← ratio of width

scale factors (k ) are not equal, hence C is not a scaled copy of B

rectangles A and C

k = = ← ratio of lengths

k = ← ratio of widths

the scale factors are not equal hence A is not a scaled copy of C

Write an equation in slope for a line that passes through (3,4) (and has a y intercept of -8)

Vlad [161]

Answer:

Part 1) The equation in slope intercept form is $y=4x-8$

Step-by-step explanation:

Part 1) Write an equation in slope-intercept form for a line that passes through (3,4) (and has a y intercept of -8)

we know that

The equation of a line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$b=-8$

$point\ (3,4)$

substitute

$4=m(3)-8$

solve for m

$4+8=3m$

$3m=12$

$m=4$

therefore

$y=4x-8$

Answer Choices : (A) 1/6 (B)5/36 (C) 1/2 (D) 1/36

Sati [7]

Answer:

$Probability = \frac{1}{6}$

Step-by-step explanation:

Given

The above table

Required

Determine the probability of a sum that is a multiple of 6

Represent the event that an outcome is a multiple of 6 with M.

List out all possible values of M

$M = \{6,6,6,6,6,12\}$

Number of M is

$n(M) = 6$

Total possible outcome is:

$n(Total) = 36$

The theoretical probability is then calculated as follows:

$Probability = \frac{Number\ of\ desired\ outcomes}{Number\ of\ possible\ outcomes}$

In this case, it is:

$Probability = \frac{n(M)}{n(Total)}$

$Probability = \frac{6}{36}$

Simplify fraction

$Probability = \frac{1}{6}$
