A bag contains blue marbles and red marbles, 75 in total. The number of blue marbles is 5 more than 4 times the number of red ma
horrorfan [7]

There are 61 blue marbles

<em><u>Solution:</u></em>

Let "b" be the number of blue marbles

Let "r" be the number of red marbles

Given that bag contains blue marbles and red marbles, 75 in total

number of blue marbles + number of red marbles = 75

b + r = 75 -------- eqn 1

The number of blue marbles is 5 more than 4 times the number of red marbles

number of blue marbles = 5 + 4(number of red marbles)

b = 5 + 4r ------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 2 in eqn 1

5 + 4r + r = 75

5 + 5r = 75

5r = 75 - 5

5r = 70

r = 14

From eqn 2,

b = 5 + 4(14) = 5 + 56 = 61

b = 61

Thus there are 61 blue marbles

From a bag containing 5 nickels, 8 dimes, and 7 quarters, 5 coins are drawn at random and all at once. What is the probability o
murzikaleks [220]

Answer:

0.13

Step-by-step explanation:

From a bag containing 5 nickels, 8 dimes, and 7 quarters, 5 coins are drawn at random and all at once

we need to select 2 nickels from 5 nickels and select 2 dimes from 8 dimes and 1 quarter from 7 quarters

There are total of 5+8+7=20 coins

select 5 coins from total of 20 coins

2 nickels can be selected from 5 nickels in 5C2 ways

5C2=\frac{5!}{2!(5-2)!} =\frac{5!}{2!(3!)!}=10

2 dimes selected from 8 dimes

8C2=\frac{8!}{2!(8-2)!} =\frac{6!}{2!(6!)}=28

1 quarter selected from 7 quarter

7C1=\frac{7!}{1!(7-1)!} =\frac{7!}{1!(6!)}=7

5 coins selected from 20 coins

20C5=\frac{20!}{5!(15)!} =15504

probability of getting 2 nickels, 2 dimes, and 1 quarter

\frac{10 \cdot 28 \cdot 7}{15504} =\frac{1960}{15504} =0.13
