A bag contains colored blocks.
3 blocks are pink
4 blocks are yellow
1 block is brown
a block will be randomly selected from the bag. what is the probability in decimal form that the block selected will be yellow?

Answers

Answer 1

Answer:

0.5

Explanation:

3+4+1= 8. So there are 8 blocks in the bag. There are 4 yellow blocks, so there is a 4/8 chance you'll get a yellow block. 4/8 can be simplified to 1/2, and 1/2 in decimal form is 0.5

Hope this helps!

Answer 2
The answer is 0.5 I’m really bad at explaining so I’m sorry!

What is the connection between linear systems and linear functions?

Explain.

Answers

Answer: While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).

Step-by-step explanation: Hope this helps :)

A linear function of one variable is one whose graph is a straight line. In general, a linear function can be a function of one or more variables. Each term in a linear function is a polynomial of degree one in one of the variables, or a constant. So ()=3+2
f
(
x
)
=
3
x
+
2
is a linear function.

A linear equation has an equals sign, with linear functions on both sides. You can always move everything to one side of the equation, so solving a linear equation is essentially finding the zero of some linear function. 3+2=0
3
x
+
2
=

is a linear equation. A little algebra yields =−23.
x

It does get murky because the notation is overloaded. Consider =3+2.

x

We normally think of that as a function of a single variable
x
, pretty much just an abbreviation for ()=3+2
f

x

. But it’s also a linear equation in two variables
x

That equation’s solutions are the zeros of the linear function of two variables (,)=3−+2

Answer:

A. Each large envelope costs $1.42

Step-by-step explanation:

To solve this, we want to set up a system of equations.

The first customer paid $12 for 14 postcards & 5 large envelopes.

The total number of dollars paid is $12. This will be on one side of the equal sign.They bought 14 postcards. This will be represented by 14p.They bought 5 large envelopes. This will be represented by 5eThe equation will be: 14p + 5e = 12

The second customer paid $24.80 for 10 postcards & 15 large envelopes.

The total number of dollars paid is $24.80. This will be on one side of the equal sign.They bought 10 postcards. This will be represented by 10p.They bought 15 large envelopes. This will be represented by 15eThe equation will be: 10p + 15e = 24.80

Now let's set up our equations together.

14p + 5e = 12

10p + 15e = 24.80

We will solve this through elimination. First we want to eliminate one variable at a time. We will start with e because we can see that 5 and 15 will simplify easily.

Multiply the first equation by -3 to cancel out the variable e.

-3(14p + 5e = 12) = -42p - 15e = -36

Now set this up for elimination.

-42p - 15e = -36

10p + 15e = 24.80

______________

-32p = -11.2

Divide both sides by -32.

p = 0.35

Each postcard costs $0.35.

Now that we know the value of p, let's plug it into one of equations to find e.

14p + 5e = 12

14(0.35) + 5e = 12

4.9 + 5e = 12

5e = 7.1

e = 1.42

Each large envelope costs $1.42

Check your answer by plugging both values back into the equation you haven't used yet.

10p + 15e = 24.80

10(0.35) + 15(1.42) = 24.80

3.5 + 21.3 = 24.80

24.80 = 24.80

Your answer is correct.

Hope this helps!

-Todo <3

Step-by-step explanation:

9/4=2.25

180/2.25=80

Answer:

48

Step-by-step explanation:

for this we need to figure out the rate of change and the price for one notebook, we can take any point on the graph like 12 notebooks for $27

first divide the price by the amount of books

27 / 12 = 2.25

and BOOM step one is done, we now know the cost for one notebook, not to find out how many notebooks $108.00 will give you, we will divide again, this time we divide the goal cost by the unit cost

108.00 / 2.25 = 48

and that is the amount of notebooks that $108.00 will get ya, please comment if you have questions about the process or how it can be used in similar situations

This is the previous problem: A rabbit started at point 0 and made 3 jumps a jump of 4 units then a jump of 2 units and then a jump of 1 unit we do not know the direction of either jump where on the line could the rabbit be.

This is my question: next time, the rabbit from the previous problem started at 10. Where on the number line can he be after the same three jumps?

Answers

Answer:

Q1: The rabbit could be at eight different numbers of the number line: -7, - 5, - 3, - 1, 1, 3, 5, and 7.

Q2: 13

Step-by-step explanation:

Q1: Let's simulate each of the jumps of the rabbit in all the possible directions, as follows:

Option 1: - 4 - 2 - 1 = -7

Option 2: - 4 - 2 + 1 = -5

Option 3: - 4 + 2 - 1 = - 3

Option 4: - 4 + 2 + 1 = - 1

Option 5:  4 - 2 - 1 = 1

Option 6: 4 - 2 + 1 = 3

Option 7: 4 + 2 - 1 = 5

Option 8: 4 + 2 + 1 = 7

Q2: If the rabbit started at 10 you would add 3 to 10 and get 13.

Which graph of ordered pairs shows a proportional relationship?


(Provide an explanation if you can! Thanks.)

Answer:

1 and 4 i think they look proportional

Answer:

Only the first graph

Step-by-step explanation:

In order for a equation to be proportional it has to have a straight line (which indicates that it has a constant rate of change.) and it has to go through the origin

If  you were to draw a line straight through the ordered pairs of graph 1 it would be a straight line and it would go through the origin (0,0)

therefore graph one would show a proportional relationship
