For a set of ten numbers, removing the largest number decreases the average by 1. Removing the smallest number increases the average by 2 . What is the positive difference between the largest and the smallest of these ten numbers?
Hint: Sometimes thinking of the average of a list of numbers as "balancing" the list helps solve problems.
Hint: How far must the largest number be from the average of the origiNl list?

Answer:

x=2cm

Step-by-step explanation:

By using pythagoras theorem:

H²=P²+B²

x²=1.6²+1.2²

x=2cm

The shape has 2 pairs of parallel lines and 4 sides of equal length. The shape is a rhombus. Jabar is correct.

Also, I-Ready? Is that like a practice thing or the actual test? Because there is no way that you can take a picture of that in school

Answer:

Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly travel in 24 hours if it continues to fly at the same speed?

The dependent variable is time, the equation is y = 22x, and the dragonfly will travel 528 miles.

The dependent variable is time, the equation is x = 22y, and the dragonfly will travel 1,056 miles.

The dependent variable is distance, the equation is y = 22x, and the dragonfly will travel 528 miles.

The dependent variable is distance, the equation is x = 22y, and the dragonfly will travel 1,056 miles.

Answer:

b= -48

Step-by-step explanation:

by transposing,

43=59+b/3

b/3+59=43

b/3=43-59

b/3= -16

b= -16×3

b= -48

therefore the answer is b= -48

Answer:

13

Step-by-step explanation:

3x4+12+1+13

Answer: See in the explanation

Step-by-step explanation:

The domain is all of the X values in a set.  

The range is all of the Y values in a set.

You can tell if a set of coordinate pairs is a function if each x value corresponds to 1 Y value. For example, lets say we have an x value of 3. This X value can only correspond to ONE y value. So if the x value 3 corresponded to , e.g, 4, or 7 as y values, it would not be a function because 1 x value has to have only 1 y value. 

a. {(0,9), (8, 1), (-1, 9), (9, 8), (1, -1)}

* This relation is a function, because there aren't many of the same x value numbers.

* The domain is {0, 8, -1, 9, 1}. Those are all of the X values

* The range is {9, 1, 9, 8, -1} (All of the Y values)

b. {(62, -3.1), (61, -3.1), (60, -3.1), (-3.1, -3.1)}

* This relation is a function, because even though all of the y values are the same , the x values are different.

* The domain is {62, 61, 60, -3.1}.

* The range is {-3.1, -3.1, -3.1, -3.1}

c. {(123,876), (-15, 2.6), (2.6, -15), (123, 1), (-87, -0.98)}

* This relation is a function, because all of the X values are different

* The domain is {123,876, -15, 2.6, 123, -87}

* The range is {0, 2.6, -15, 1, -0.98}

d. {(2.9, 0), (2.9, 1), (2.9, 2), (2.9, 3)}

* This relation is not a function. All of the x values are the same, and for this reason, they all have different y values.

* The domain is {2.9, 2.9, 2.9, 2.9}

* The range is {0, 1, 2, 3}

Answer:

n represents 5

Step-by-step explanation:

10 divided by 5 = 2

do the same operation for 25...

25 divided by 5 = 5

Answer:

5

Step-by-step explanation:

becaus 10/25 is .4 and 2/5 is .4

By using the graph, all of the true statements that apply include the following:

B. The variables are dollars and hours.

C. Hours is the independent variable and dollars is the dependent variable.

F. The relationship is y = 3.50x.

In Mathematics and Geometry, a proportional relationship is a type of relationship that produces equivalent ratios and it can be modeled or represented by the following mathematical equation:

y = kx

Where:

Next, we would determine the constant of proportionality (k) by using the various data points from table D as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = 3.5/1 = 7/2 = 10.5/3

Constant of proportionality, k = 3.50

Therefore, the required linear function is given by;

y = kx

y = 3.50x

Answer:

1.) 6

2.) -1

3.) 36

4.) 1/3

5.) 90

Step-by-step explanation:

1.) -12/a

-12/a -> -12/2

=6

2.) a+ (-b)

a+(-b) -> 2+(-3)

=-1

3.) 3a (12-2b)

3a(12-2b) -> 3(2) (12-2x3)

6(12-6)

6(6)

=36

4.) 2a-c/b

2a-c/b -> 2(2)-5/3

4-5/3

=1/3

5.) 3abc

3abc-> 3x2x3x5

=90

Answer:

60%

Step-by-step explanation: Because the graph flattens out at about 60% meaning that that is the most likely percentage.

Answer:

m = 8

Step-by-step explanation:

turn it into a square and then you can divide 48 by 6 and the answer is 8

Answer:

the answer for the first one is 8 because we need to divide the area which is 48 by 6 to get the answer which is 8 so we multiply  6 times 8 to check if it is 48 and yes sir it is.

In the second one you need to divide 42 by 6 not by 4 and when you do that you get 7 so we multiplied 6 times 7 to check if the area is 42 and yes it is sir again so the first one is 8 and the second one is 7

Answer:

[tex]\boxed{\sf volume = 320 \ ft^3}[/tex]

Explanation:

Volume of triangular prism = 1/2 × Base × Height × Length

Identify the following:

Find Volume:

[tex]Area \: of \: triangle = ½ × height× width \\ area = \frac{1}{2} \times 8 \times \frac{20}{3} \\ area = \frac{{ \cancel8} {}^{ \: \: 4} }{ \cancel2} \times \frac{20}{3} \\ area = \frac{80}{3} {ft}^{2} [/tex]

Now for volume :-

Volume = area of triangle (2D ) × length

[tex]volume = area \times length \\ vol = \frac{80}{3} \times 12 \\ vol = \frac{80}{ \cancel3} \times { \cancel{12}} {}^{ \: \: 4} \\ volume = 320 {ft}^{3} [/tex]

Answer:

x = 3

y = 1

Step-by-step explanation:

So to solve this by addition we have to add both x's, y's and the numbers on the other side of the equal sign:

x + y = 4

x - y = 2

Both y's will cancel out because we are subtracting y from y

Adding 4 +2 = 6

2x = 6          (adding both x gets 2x)

x = 3

Now that we found x we can find y by plugging it into either equation:

3 + y = 4

y = 1

We can check these in both equations:

3 + 1 = 4        4 = 4

3 - 1 = 2        2 = 2

These answers are then proven correct!

I hope this helps! Good luck!

During the first week of her training, she runs 200 meters.  On the second week, she plans to run 50% more.  

Now, how do you calculate this?

To increase 200 meters by 50%, multiply by 1.5

The second week she pans to run 450 meters.

Since there are only 3 weeks, do it again!

The thrid week, she plans to run 675 meters.

Since she runs the same ammount each day of the week, the calculation is simple.

7(200) + 7(450) + 7(675)

In these three weeks, she runs 9275 meters.

OR, she runs 10143.26 yards.

Answer:

1005.3 [tex]ft^{3}[/tex]

Step-by-step explanation:

V=π r^2 h = π · 42· 20 ≈ 1005.30965 ---> 1005.3

Answer:

the answer to this question should be 1004.8 because first you need to use this formula to find the volume of a cylinder which is V=TTr^2h so remember the radius is half of the diameter.

So the half of 8 is 4 so 4 is the radius but remember that 4 is to the power of 2 in the exponent so the answer should be 16 because you multiplied 4 times 4 equals 16.

Then we need to multiplied 16 times 3.14 and 20 and when we do that we get an answer of 1,004.8 so 1004.8 feet^3 is the correct answer.

Step-by-step explanation: :DDDDD give brainliest to the first people that answer first than me if you want and have a great day.

Here, the focus of the parabola is (2,0) and directrix is x=−2.

So, equation of parabola will be y2=4ax

Here,a=2.So, Equation becomes,

y2=4∗2x⇒y2=8x, which is the required equation of parabola.
