Step-by-step explanation:

7+(4*1/2)=2+7=9

Answer:

(Shown below)

Step-by-step explanation:

The Mean, AKA the average is all of the numbers added up, then divided by how many numbers there were. For example, take this data set:

3, 5, 10, 6, 5, 5

We add up all of the numbers:

3 + 5 + 10 + 6 + 1 + 5 + 5 = 35

Now, we divide by how many numbers there were. Since there were 7 numbers, we do:

[tex]\frac{35}{7} = 5[/tex]

Therefore, 5 is our Mean.

Next up, the Median. Median is just the number in the middle of the data set, but we have to put it from least to greatest. Here it is again:

3, 5, 10, 6, 1, 5, 5

1, 3, 5, 5, 5, 6, 10

As you can see, the 5 is in the middle, so it is our Median.

Now the Mode. The Mode is number that occurs most often. Again, it's easier to put the numbers from least to greatest. The data set:

3, 5, 10, 6, 1, 5, 5

1, 3, 5, 5, 5, 6, 10

So, the 5 is the Mode because it occurs thrice, while the other numbers only occur once. Remember the Mode is what the number is, not how many times it repeats.

Lastly, the Range. The Range is just the difference of the largest number to the smallest number. This one also requires to be from least to greatest.

1, 3, 5, 5, 5, 6, 10

10 - 1 = 9

Therefore, the Range of the data set is 9. I hope this helps you!

Answer:

The slope is 2!

Step-by-step explanation:

To find the slope of a line, you must first find two points that are EXACTLY on the grid.

Two points I picked are (-1, -2) and (0,0).

Now count how many points the numbers are far from each other up and down. So, starting from (-1,-2) to (0,0), the points are two points away from each other vertically (on the y-axis)

Now find how far they are on the x-axis

Once again I counted and they are 1 point away from each other horizontally.

Now you need to turn these two points into a fraction.

Slopes are rise/run or y/x

So:

The slope is 2/1.

Also, the slope is positive as the line ascends (goes up).

If the line were negative or going down, the slope would be negative, but the line is positive.

So, the answer is 2!

0.25% chance or 1/4th.

You have a 50/50 chance of getting heads or tails on a throw. .50 for each.

If you do get heads, there's the same chance of getting another heads.

Multiply the .50% chance of getting heads by .50 again, and you end up with a 0.25% chance total of getting heads twice in a row.

Answer:

The solution is given below:

Step-by-step explanation:

Given that

The equation is 4.2x

It could present the total price for the no of goods

Here we take an example

The price per chips is $4.2

And, the number of chips purchased be x

And, the total price would be y

So if 5 chips were purchased, so the total price would be

y = $4.2 (5)

= $21

hence, the above represent the description

Answer:

600 times

Step-by-step explanation:

5400000 ÷ 9000 = 600

Answer:

500,000

Step-by-step explanation:

so here's what's up, because it says about we can round 28.6 acres up to about 30. and there is 15,000,000 water every time. its a rather simple question. because all of the water needs to be divided equally, we must divide 15,000,000 by 30. and that makes a total of 500,000. so your answer is 500,000. but be carful because sometimes you must do the opposite.

Answer:

524,475.5 gallons

Step-by-step explanation:

15,000,000 / 28.6 = 524,475.5 gallons

Answer:

x=41, y=24

Step-by-step explanation:

Given data

We are given the expression

-2x - 7y = -250  

4x - y = 140

Multiply eqn 1 by 1 and eqn 2 by 7  and minus we have

  -2x - 7y = -250

-   28x-7y=   980

  -30x+0= -1230

-30x=-1230

30x=1230

x= 1230/30

x=41

Put x=41 in eqn 1

-2(41) - 7y = -250

-82-7y= -250

-7y= -250+82

-7y=-168

7y=168

y=168/7

y= 24

Answer:

1) -5+(-1)+7

-6+7

=1

2) 19+(-3)+6

16+6

=22

Answer:

1: 1

2: 22

Step-by-step explanation:

1 ) -5 + (-1) is -6, because they both have the same sign.

-6+7} when there is a negative and a postive, put the postive in front

so it will look like this 7-6 which is 1

2) 19+(-3) is basically 19-3, which is 16, and 16+6=22

Extra note:

when you see n+(-n), always remove the + sign and subtract

when you see -n+n, always switch the roles of the two

when you see -n+-n, remove the - sign and add it back later

when you see -n-n, think of -n+n

I hope these helps :)

Answer:

8) scale factor: 3

angles Q & L, S & N, r & M

sides 10 x 3 = 30, 6 x 3 = 18, 13 x 3 = 39

9) scale factor: 0.4

angles B & F, C & G, D & H, A & E

sides 9 x 0.4 = 3.6, 7.5 x 0.4 = 3, 10 x 0.4 = 4, 12 x 0.4 = 4.8

The scale factor for part (8) is 3, angles Q & L, S & N, R & M, for part (9) is 0.4 and angles of pair are congruent B & F, C & G, D & H, A & E

The ratio among comparable dimensions of an object and a model with that object, known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

8)

Scale factor for the triangle LMN:

Let's suppose the scale factor is x

3x= 30 ⇒ x = 3

6x= 18  ⇒ x = 3

13x=39  ⇒ x = 3

So the scale factor is 3

Angles Q & L, S & N, R & M

39/13 = 30/10 = 18/6 = 3

9)

Scale factor for the triangle LMN:

Let's suppose the scale factor is y

12y= 4.8 ⇒ x = 0.4

9x= 3.6  ⇒ x = 0.4

10x=4  ⇒ x = 0.4

So the scale factor is 0.4

Angles  B & F, C & G, D & H, A & E

4.8/12 = 3.6/9 = 4/10 = 0.4

Thus, the scale factor for part (8) is 3, angles Q & L, S & N, R & M, for part (9) is 0.4 and angles of pair are congruent B & F, C & G, D & H, A & E

Answer:

2. X^2-7x+3

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Given that the function h(x) = 2x-9 is translated up 5 united to become a new function, i(x)

To find: Equation of new function

The graph of a function can be moved up, down, left, or right by adding to or subtracting from the output or the input.

Adding to the output of a function moves the graph up

Therefore,

Given function is:

h(x) = 2x - 9

Translated up by 5 units

Therefore, new function is:

i(x) = h(x) + 5

i(x) = 2x - 9 + 5

i(x) = 2x - 4

Thus Option B is correct
