Question is not proper, Proper question is given below.

There are some nickels, dimes, and quarters in a large piggy bank. For every 2 nickels, there are 3 dimes. For every 2 dimes, there are 5 quarters. There are 500 coins in all. How many nickels, dimes, and quarters are in the piggy bank? How much are the coins in the piggy bank worth all together?

Answer:

There are 80 nickels, 120 dimes and 300 quarters in the piggy bank.

The piggy bank is worth $91.

Step-by-step explanation:

Let Number of Nickels be represented by 'n'.

Let Number of Dimes be represented by 'd'.

Let of Quarters be represented by 'q'.

Now Given:

For every 2 nickels, there are 3 dimes.

2 n = 3 d

1 n = number of dimes.

We will use Unitary method to find the same.

Number of 1 dimes d = \frac{3}{2}n

Also Given:

For every 2 dimes, there are 5 quarters.

2 d = 5 q

1 d = number of quarters

We will use Unitary method to find the same.

Number of 1 quarter q = \frac{5}{2}d

Also Given:

Total Number of coins = 500

n+d+q=500

Now d = \frac{3}{2}n

AND q = \frac{5}{2}d = \frac{5}{2} \times\frac{3}{2}n = \frac{15}{4}n

So Substituting the values we get;

n+\frac{3}{2}n+\frac{15}{4}n=500

Taking LCM we get making denominator as 4.

\frac{4}{4}n+\frac{3\times2}{2\times 2}n+\frac{15\times 1}{4\times 1}n=500\\\\\frac{4}{4}n+\frac{6}{4}n+\frac{15}{4}n=500\\\\\frac{4n+6n+15n}{4}=500\\\\\frac{25n}4 =500\\\\25n = 500\times 4\\\\25n =2000\\\\n=\frac{2000}{25}=80

Hence number of Nickels n = 80

Number of Dimes d = \frac{3}{2}n=\frac{3}{2} \times 80 = 120

Number of Quarters q = \frac{15}{4}n= \frac{15}{4} \times 80 = 300

Hence There are 80 nickels, 120 dimes and 300 quarters in the piggy bank.

Now we know that;

1 nickel = $0.05

so 80 nickels  = 0.05\times80= $4

1 dime = $0.1

so 120 dimes = 0.1\times120= $12

1 quarter = $0.25

so 300 quarters = 0.25\times300= $75

So Total money = $4+$12+$75 = $91

Hence the piggy bank is worth $91.

A large manufacturing firm tests job applicants who recently graduated from college. The test scores are normally distributed wi
anzhelika [568]

Answer:

lowest score a college graduate must earn to qualify for a responsible position is 578

correct option is D. 578

Step-by-step explanation:

given data

mean = 500

standard deviation = 50

distribution = 6 %

to find out

What is the lowest score a college graduate must earn to qualify for a responsible position

solution

we know that here Probability P that is express as

P ( Z > x ) = 100% - 6%      .....................1

so with the help of normal table

here value of Z is =  1.55 from cumulative probability 0.94

so by z score formula here x will be

x = z × standard deviation +  mean    ................2

so put here value

x = 1.55 × 50 + 500

x = 577.7387 ~ 578

so lowest score a college graduate must earn to qualify for a responsible position is 578
