A bag contains 7 red marbles, 5 yellow marbles, 6 blue marbles, 4 green marbles, and 3 orange marbles. What is the probability o

baherus [9]

The probability of randomly selecting a yellow marble out of the bag is $\frac{1}{5}$

Step-by-step explanation:

A bag contains:

7 red marbles
5 yellow marbles
6 blue marbles
4 green marbles
3 orange marbles

We need to find the probability of randomly selecting a yellow marble out of the bag

Probability is the ratio of number of favorable outcomes to the total number of possible outcomes P(A) = $\frac{n(A)}{n(outcoms)}$

∵ A bag contains 7 red marbles, 5 yellow marbles, 6 blue

marbles, 4 green marbles, and 3 orange marbles

- Add all the color to find the number of total marbles

∴ n(all) = 7 + 5 + 6 + 4 + 3 = 25

∵ There are 5 yellow marbles

∵ P(yellow) = $\frac{n(yellow)}{n(all)}$

∴ P(yellow) = $\frac{5}{25}$

- Divide up and down by 5 to simplify the fraction

∴ P(yellow) = $\frac{1}{5}$

The probability of randomly selecting a yellow marble out of the bag is $\frac{1}{5}$

David had 80 dollars from washing cars

Tomtit [17]

Answer:

It cost 30$

Step-by-step explanation:

Since 50% is 1/2 we put 80/2

so we have 40

25% is 1/4 we put 40/4=10 40-10=30

so the answer is 30

Given that √5 = 2.24 and √50= 7.07 , find <br> √500 and √0.5

sineoko [7]

Answer:

see explanation

Step-by-step explanation:

using the rules of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

$\sqrt{\frac{a}{b} }$ ⇔ $\frac{\sqrt{a} }{\sqrt{b} }$

then

$\sqrt{500}$

= $\sqrt{100(5)}$

= $\sqrt{100}$ × $\sqrt{5}$

= 10 × 2.24

= 22.4

-------------------------------

$\sqrt{0.5}$

= $\sqrt{\frac{50}{100} }$

= $\frac{\sqrt{50} }{\sqrt{100} }$

= $\frac{\sqrt{50} }{10}$

= $\frac{7.07}{10}$

= 0.707

Please answer this please

TiliK225 [7]

Answer:

100

Step-by-step explanation:

$4\times(2+3)^{2}$

This can be turned into:

$4\times5^{2}$ (if we add the numbers inside the brackets)

Following PEDMAS, this becomes:

$4\times25$ which equals $100$

∴ $4\times(2+3)^{2}=100$
