Anurak has nickels, dimes, and pennies in his pocket. The coins in Anurak's pocket have a total value of 75 cents. He has three more nickels than dimes and five times as many pennies as dimes. How many coins of each type does Anurak have?

Answers

Answer:

Anurak has 15 pennies, 6 nickels and 3 dimes.

Step-by-step explanation:

We must have these informations in mind:

1) A penny is a 1-cent coin.

2) A dime is a 10-cent coin.

3) A nickel is a 5-cent coin.

Let be x, y, z the quantities of pennies, nickels and dimes, respectively. From statement we get that to value in Anurak's pocket is represented by this mathematical expression:

0.01\cdot x + 0.05 \cdot y + 0.10\cdot z = 0.75(Eq. 1)

In addition, we get the following identities:

i)He has three more nickels than dimes

z + 3 = y(Eq. 2)

ii)And five times as many pennies as dimes

x = 5\cdot z(Eq. 3)

The system of linear equations is now reduced: (Eqs. 2, 3) in (Eq. 1)

0.05\cdot z +0.05\cdot z + 0.15 + 0.10\cdot z = 0.75

0.20\cdot z = 0.60

z = 3

The remaining variables are y = 6 and x = 15.

Answers

m = 25

25 + 2(25-5) = 65

1. parentheses first (25-5) = 20
2. multiplication 2•20 = 40
3. addition 25 + 40 = 65

Patients come into a medical clinic have a mean weight of 207.6 pounds with a standard deviation of 22.6 pounds. the distribution of weight is not assumed to be symmetric. between what two ways does Chebyshev's Theorem guarantee that we will find at least 95% of the patients? Round your answers to the nearest 10th

Answers

I know the answer it is 98.2

Answer: 105.9 lbs and 309.3 lbs

Step-by-step explanation:

By Chebyshev's Theorem, the proportion of patients with weights within 4.5 standard deviations of the mean is at least 95%.  Therefore k=4.5.

The weight that is 4.5 standard deviations less than the mean is 207.6−4.5(22.6)=105.9 pounds.

The weight that is 4.5 standard deviations greater than the mean is 207.6+4.5(22.6)=309.3 pounds.

So at least 95% of the patients have weights between 105.9 and 309.3 pounds.
