Solve the system of linear equations by elimination.

2x+5y=16
3x−5y=−1

Get (x,y)

Answers

Answer 1

Answer:

(3,2)

Step-by-step explanation:

2x+5y=16

3x-5y=-1

Subtract 2x from the first equation

5y=16-2x

Substitute the given value of 5y into the equation

3x-(5y)=16

3x-(16-2x)=-1

Solve for x

3x-(16-2x)=-1

3x-16+2x=-1

5x-16=-1

5x=15

x=3

Substitute the given value of x into the equation

3x-5y=-1

3*3-5y=-1

Solve

3*3-5y=-1

9-5y=-1

-5y=-10

y=2

Instructions
In this experiment, you will be using two different coins as a simulation for a real-world compound event.

Suppose that a family has an equally likely chance of having a cat or a dog. If they have two pets, they could have 1 dog and 1 cat, they could have 2 dogs, or they could have 2 cats.

What is the theoretical probability that the family has two dogs or two cats?
Describe how to use two different coins to simulate which two pets the family has.
Flip both coins 50 times and record your data in a table like the one below.

Result Frequency
Heads, Heads
Heads, Tails
Tails, Heads
Tails, Tails
Total 50
Based on your data, what is the experimental probability that the family has two dogs or two cats?
If the family has three pets, what is the theoretical probability that they have three dogs or three cats?
How could you change the simulation to generate data for three pets?

Answers

This is 10 point in this long question.

Answer:

see below <3 i hope this helps!

Step-by-step explanation:

What is the theoretical probability that the family has two dogs or two cats? (1/2)

The choices are dd, dc, cd, cc

There are 4 choices = dd or cc/ total = 2/4 = 1/2

Let the heads of the coin be dogs and the tails of a coin be cats

Flip two coins and coin A is the first pet and coin B is the second pet

heads , heads = 10

heads, tails  14

tails heads  =13

tails tails =  13

         total 50

Experimental probability  2 dogs or 2 cats = ( hh, tt) /total = ( 10+13) /50 =                    23/50

If we had 3 pets  

what is the theoretical probability that they have three dogs or three cats?

ddd, ddc, dcd, dcc, ccc, ccd ,cdc, cdd

There are 8 options

ddd or ccc/ total = 2/8 = 1/4

Let the heads of the coin be dogs and the tails of a coin be cats

Flip three coins and coin A is the first pet and coin B is the second pet Coin C be the third pet. ///////////// Did this help? :3 If so please give brainliest bc this took a while to type

An artist mixes paint to make new colors.
She uses 1/3 cup of red paint and 1/3 cup of yellow paint to make a batch of orange paint.
If the artist has 2 cups of red paint available and 3 cups of yellow paint available, how many batches of orange paint can she make?
Enter your answer in the box.

Answers

Answer:

6 batches of orange paint can be made.

Step-by-step explanation:

2 cups of red paint can go to 6 cups of 1/3 a batch of red paint, and 3 cups of yellow paint can go to 9 cups of 1/3 a batch of yellow paint.

She then combines 6 cups of 1/3 cups of red paint with 6 cups of 1/3 cups of yellow paint. The reason it is not 9 is that she doesn't have 3 extra 1/3 cups of red paint.

6 batches of orange paint can be made, with 3 extra 1/3 cups of yellow paint.

A storeowner made a list of cake flavors sold in the last month. They sold 120 vanilla cakes, 270 chocolate cakes, and 110 red velvet cakes. Based on this data, what is the probability that the next customer will buy a red velvet cake? Express your answer as a fraction and percent

Answers

Answer:

The fractional/percentage probability of someone buying a Red Velvet cake is 110/500, or 0.22.

Step-by-step explanation:

First, note the amount of red velvet cakes. There are 110 cakes in this flavor. Next, add up the total amount of cakes. There are 500 cakes in the store. This gives us 110/500. Finally, express 110/500 as a decimal, 0.22.
