Victoria used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. The results are shown in the tables below:Color of
Marble
Number of
Times Rolled
Blue
18
Green
20
Yellow
12
Heads Tails
20 30
Using Victoria's simulation, what is the probability of pulling a blue marble and the coin landing tails up?
540/2500
48/50
38/50
360/2500

Answers

Answer 1

Answer:

Answer: $(540)/(2500)$

Step-by-step explanation:

Formula:

$\text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}$

Using Victoria's simulation :

Total number of outcomes = Total number of times marbles rolled x Total number of times coin flipped

= 50 x 50 =2500

Favorable outcomes = Total number of times pulling a blue marble and the coin landing tails up

= Number of times blue marble rolled x Number of times coin flipped to tail

= 18 x 30=540

Now, the the probability of pulling a blue marble and the coin landing tails up will be :-

$=(540)/(2500)$

Answer 2

Answer:

Answer:

C. 540/2500

Step-by-step explanation:

18 times 30=540

50 times 50= 2500

How do I solve forax+by=c

Answers

Answer:

Subtract ax from both sides. ax + by − ax = c − ax.

Simplify. by = c − ax.

Divide both sides by b ; b ≠ 0. by b = c b − ax b ; b ≠ 0.

Simplify. y = c − ax b ; b ≠ 0.

What is the whole to which a percent is compared?

Answers

The whole to which a percent is compared is 100. This is evident in both the name, and the method of calculation of percentages. The name, is broken to "per" and "cent" meaning every 100. Also, when we calculate percentages, we find the ratio of the given amount to the total amount. If we don't multiply by 100, we see that this ratio is compared to the ratio of the percentage to 100.

Reorder the following equations in ascending order of steepness.y = 15x + 5y = 0.15x - 1y = xy = x + 100

Answers

Equations don't have steepness. "Steepness" is the slope of the line you get when you graph the equation. If you always massage the equation into the form
[ y = (something times x) + something },
then the number that multiplies 'x' is the slope of the graph..

y = 15x + 5
The slope is 15.

y = 0.15x - 1
The slope is 0.15 .

y = x
The slope is 1. ( y = 1x )

y = x + 100
The slope is 1. ( y = 1x + 100 )
