Recall from Example 1 that whenever Suzan sees a bag of marbles, she grabs a handful at random. She has seen a bag containing th

hammer [34]

Answer:

Required Probability in the lowest terms as fractions = $\frac{15}{182} =0.0824$

Step-by-step explanation:

Step 1:-

Given Suzan has three red marbles, two green ones, five white ones, and two purple ones.

Total marbles = 3R+2G+5W+2P = 12

The number of exhaustive cases that the five marbles drawn from 12 marbles

n(S) = $12C_{5} = 792 ways$

by using formula $n_{Cr_{} } = \frac{n!}{(n-r)!r!} = \frac{12!}{(12-5)!5!}$ = 792

The number of favorable cases

She has drawn two red marbles from 3 red marbles, that is 3c₂ ways

she has drawn one marble drawn from 2 green marbles, that is 2c₁ ways

she has drawn one marble drawn from 5 white marbles, that is 5c₁ ways

she has drawn one marble drawn from 2 purple marbles, that is 2c₁ ways

The favorable cases are (n(E) = 3c₂ X 2c₁X5c₁X2c₁ = 60 ways

Required Probability = $\frac{n(E)}{n(S)}$

$Required probability = \frac{n(E)}{n(S)} = \frac{60}{792}$

Required Probability in the lowest terms as fractions = $\frac{15}{182} =0.0824$

Which graph represents the function f(x)= 2x-1/x-1

Effectus [21]

To determine which <u>graph</u> represents the <u>function</u> $f(x)=\dfrac{2x-1}{x-1}$ make following steps:

1. The vertical asymptote is $x=1.$

2. Simplify the function

$f(x)=\dfrac{2x-1}{x-1}=\dfrac{2x-1-1+1}{x-1}=\dfrac{2(x-1)+1}{x-1}=2+\dfrac{1}{x-1}.$

Then the horizontal asymptote is $y=2.$

Only option C contains graph with such asymptotes.

Answer: correct choice is C

<h3>Answer: 36%</h3>

============================================

Explanation:

There are 20 blue cards out of 10+20+25 = 55 cards total.

Divide the 20 over 55 to get

20/55 = 0.363636...

where the "36"s go on forever

So 20/55 = 0.3636 approximately

Move the decimal point over 2 spots to go from 0.3637 to 36.37%

Then round to the nearest percent: 36.37% ---> 36%

The probability of getting a blue card is approximately 36%
