Answer:

1. y ax

|
A-------------------------------B

|

------------C---------------------

|

|__________________x ax

for this, your A might be (0,5), B (5,5), C (2,2).

parallel means railroad tracks: same slope, different intercepts.

line AB in this case has a slope of 0, intercept (0,5), so y₁=0x+5 or just y₁=5

the line passing through C also has slope 0, but intercept (0,2), so y₂=0x+2 or just y₂=2

2. perpendicular means that the slopes of two lines multiply out to -1. If line AB has, for example, a slope of 2/3, then the line passing through C would have slope -3/2 (negative reciprocal). To make things easier have either point A or B be on the x or y axis

khan academy has some helpful videos :)

A weighted die comes up spots with the following probabilities: Spots 1 2 3 4 5 6 Probability 0.10 0.15 0.20 0.25 0.20 0.10 If t
Mandarinka [93]

Answer:

Probability (A sum of 10)=0.1025

Step-by-step explanation:

\begin{center}\begin{tabular}{ c c c c c c c } Spots & 1 & 2& 3 & 4& 5 & 6 \\ \\Prob & 0.10 & 0.15& 0.20 & 0.25& 0.20 & 0.10     \end{tabular}\end{center}

To find the Probability the sum is 10, we can either have

i. a 4 and a 6

ii. a 5 and a 5

Pr (A AND B) = Pr (A) x Pr(B)

Pr (A OR B) = Pr (A) + Pr(B)

Probability (A sum of 10) = Pr(getting a 4 AND a 6) OR Pr(getting a 5 AND a 5)

=(0.25 x 0.25)+(0.20 x 0.20)

=0.0625+0.04

=0.1025
