Please I Dont Have A Lot of Time
what is the median, mode, mean, and range
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!

This is a scale drawing of a Flag. The scale factor of a drawing to the actual flag is represented by the ratio 1:18. What is the area in square inches of the actual flag?
Answer:
648 in²
Step-by-step explanation:
Scale factor of drawing to actual flag = 1 : 18
This means the actual flag is 18 times bigger or larger than the drawing
To obtain the area in square inches of the actual flag :
Multiply the dimension of the drawing by 18 to obtain the actual dimension of the flag, then using the formular for the Area of a rectangle, we can obtain the actual area of the flag.
Actual width = 1 inch * 18 = 18 inches
Actual length = 2 inches * 18 = 36 inches
Actual area of flag = length * width
Actual area of flag = (18 * 36) inches
Actual area of flag = 648 in²

-2( x ) - 7(y) = 250 X
4(x ) - (y) = 140 X
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

Vhen flipping a coin, what is the probability of landings
meads and then heads again?
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.
What is the slope of the line
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!

An umbrella and a pen are sold at a discount of 8% and 3% respectively . Calculate the overall percentage discount offered on the two commodities , if the cost of the umbrella is four times that of the pen.
9514 1404 393
Answer:
7%
Step-by-step explanation:
The cost of the umbrella is 4/5 of the total cost of the two items. If the base price of the two items is 1, then the discounted price is ...
(4/5)(1 -8%) + (1/5)(1 -3%) = 0.8·0.92 +0.2·0.97 = 0.93 = 1 - 7%
The overall discount is effectively 7%.

In the Exercises below, find the scale factor. Then list all pairs of congruent angles and write the ratios of the corresponding side lengths in a statement of proportionality.
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

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

A corn field has an area of 28.6 acres. It requires about 15,000,000 gallons of water. About how many gallons of water per acre is that?
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

G = 139
G = 41
G = 10
G = -10
Answer:
G = 41
Step-by-step explanation:
Since G and E are parallel to each other, they have the same degrees.
5x - 9 = 3x + 11
Solution: Shift numbers to one side and numbers to another side.
3x to shifted to the left side, so it becomes negative. -9 is shifted to the right side, so it becomes positive.
5x - 3x = 9 + 11
2x = 20
x = 20 ÷ 2 = 10
Find G.
5x = 10 x 5 = 50
50 - 9 = 41°
Answer:
m∠G = 10
Step-by-step explanation:
Angles E and G are equal to each other, so we can set up an equation where both statements equal each other to solve for x.
[tex]3x+11=5x-9[/tex]
We then combine like terms, so the equation becomes:
[tex]3x-5x = -9-11[/tex]
Then we calculate it, giving us:
[tex]-2x=-20[/tex]
From here, we divide both sides by -2 so we can isolate the x:
[tex]\frac{-2x}{-2} = \frac{-20}{-2}[/tex]
The -2's cancel out, so we're left with:
[tex]x = \frac{-20}{-2}[/tex]
Which equals:
[tex]x = 10[/tex]

Suppose the function h(x) = 2x - 9 is translated up 5 units to become a new function,
i(x)
What's the equation of the new function?
A) i(x) = 2x - 4
B) i(x) = 77-9
C) i(x)= 2x- 14
D) i(x)= 7x- 4
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
