The number of half dollars coins are 5 and the number of the quarters dollars coins are 12.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

You have a cup with 17 coins inside.

The total inside the cup is $5.50.

Let x be the number of half dollars and y be the number of the quarters dollars.

Then the equations will be

             x + y = 17  ............1

0.5x + 0.25y = 5.5 ...........2

By solving equations 1 and 2, we have

x = 5 and y = 12

More about the linear system link is given below.

List three different combinations of coins, each with a value of 30% of a dollar
ipn [44]

Answer:

Step-by-step explanation:

30% of a dollar...

0.30(1) = 0.30.....so 30% of a dollar is 30 cents

1 quarter and 1 nickel = 0.30

3 dimes = 0.30

2 dimes and 2 nickels = 0.30

6 nickels = 0.30

3 nickels, 1 dime, 5 pennies = 0.30

10 pennies, 2 nickels, a dime = 0.30

30 pennies = 0.30

take ur pick :)

PLEASE HELP!!!! WILL GIVE BARAINLYIST!!!!

Experimental probability = 1/5

Theoretical probability = 1/4

note: 1/5 = 0.2 and 1/4 = 0.25

=============================================

How I got those values:

We have 12 hearts out of 60 cards total in our simulation or experiment. So 12/60 = (12*1)/(12*5) = 1/5 is the experimental probability. In the simulation, 1 in 5 cards were a heart.

Theoretically it should be 1 in 4, or 1/4, since we have 13 hearts out of 52 total leading to 13/52 = (13*1)/(13*4) = 1/4. This makes sense because there are four suits and each suit is equally likely.

The experimental probability and theoretical probability values are not likely to line up perfectly. However they should be fairly close assuming that you're working with a fair standard deck. The more simulations you perform, the closer the experimental probability is likely to approach the theoretical one.

For example, let's say you flip a coin 20 times and get 8 heads. We see that 8/20 = 0.40 is close to 0.50 which is the theoretical probability of getting heads. If you flip that same coin 100 times and get 46 heads, then 46/100 = 0.46 is the experimental probability which is close to 0.50, and that probability is likely to get closer if you flipped it say 1000 times or 10000 times.

In short, the experimental probability is what you observe when you do the experiment (or simulation). So it's actually pulling the cards out and writing down your results. Contrast with a theoretical probability is where you guess beforehand what the result might be based on assumptions. One such assumption being each card is equally likely.
