Answer:

Independent

Step-by-step explanation:

with replacement the total number of tiles will always remain the same,i.e the sample size will not be changed. so the events are independent.

(-5,2) (-5,-1) how to find the slope-intercert form

Novay_Z [31]

The slope-intercept form of (-5,2) (-5,-1) is undefined

<u>Solution:</u>

Need to find the slope intercept form of line passing through two point (-5,2) (-5,-1).

Slope intercept form of line passing through $\left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right)$ is given by

$y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\left(x-x_{1}\right)$

$\text { Here in this problem } \mathrm{x}_{1}=-5, \mathrm{x}_{2}=-5, \mathrm{y}_{1}=2 \text { and } \mathrm{y}_{2}=-1$

On Substituting the values we get the slope intercept form of given points,

$\begin{array}{l}{y-2=\frac{-3}{0}(x+5)} \\\\ {y-2=-\frac{3(x+5)}{0}}\end{array}$

= undefined

Hence the slope intercept form of given points is undefined

Line AB contains points A(4, 5) and B(9, 7). What is the slope of AB? 5 2 2 5 N/ur un in ni 2 5 o 2

IRINA_888 [86]

Answer:

The answer is

$\frac{2}{5} \\$

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(4, 5) and B(9, 7).

The slope is

$m = \frac{7 - 5}{9 - 4} = \frac{2}{5} \\$

We have the final answer as

$\frac{2}{5} \\$

Polygon stuv is reflected over the x axis and then over the y axis to create wxyz . Which of the following sides are congruent ?

JulsSmile [24]

Answer:

ST and WX are congruent ⇒ first answer

Step-by-step explanation:

∵ S = (-5 , -4) , T = (-3 , -1) , U = (-1 , -3) , V = (-2 , -6)

∵ STUV reflected over the x-axis

∴ S' = (-5 , 4) , T' = (-3 , 1) , U' = (-1 , 3) , V' = (-2 , 6)

∵ S'T'U'V' reflected over the y-axis

∴ S" = (5 , 4) , T" = (3 , 1) , U" = (1 , 3) , V" = (2 , 6)

∵ W = (5 , 4) , X = (3 , 1) , Y = (1 , 3) , Z = (2 , 6)

∴ S"T"U"V" is WXYZ

∴ ST and WX are congruent
