As you can see now.. Median is 13

[RevyBreeze]

Answer:

Median Arrayed Data :From ascending order; 5,6,6,9,11,13,13,13,15,18,24,28,33,36,48

Now,

Median= n+1/2

=15+1/2

=16/2

=8

5,6,6,9,11,13,13,13,15,18,24,28,33,36,48

Median = 8 th term= 13.

Hence the median is 13.

Answer:80

Assume the number to be 400 for instance,

10% of 400 increased = 400 + ( 10/100 × 400 )

= 400 + 40 = 440

The resulting number decreased by its 10% = 400 - (10/100 × 400)

= 400 - 40 = 360

Now, net decrease = 440 - 360 = 80

Answer:

400.

10% of 400 is 40 (Simply reduce the hundreds place to the tens place)

So now we have 440.

Decrease it by 10% again, and that brings you right back to 400.

Answer: The length of the rectangle would be 20 inches and the width would be 14 inches.

Step-by-step explanation:

If the length is 20, first, it’s 6 more than 14, and second it would add up to 40. If the width is 14, it’s 6 less than 20, and adds up to 28. If you add those two together, you’d get your total of 68 inches for the perimeter!

Answer: In 4 HOURS they will be 468 miles apart.

Step-by-step explanation:

1st car DATA:

rate = 59 mph ; time = x hrs. ; distance = 59x miles

2nd car DATA:

rate = 58 mph ; time = x hrs. ; distance = 58x miles

EQUATION:

distance + distance = 385

59x + 58x = 468

117x = 468

x = 4 hours.

Answer:

5.928 liters is the correct answer

Step-by-step explanation:

Since 1 milliliter is 0.001 liters

Multiply both values by 5928.

Therefore... 5928 milliliters equals 5.928 which is letter D

Answer:

The answer is 0.5928 liters

Step-by-step explanation:

1 liter is made of 1000 milliliters

So 5,929 ÷ 1000

gives us 0.5928

-3.75 +4.35 -6.55

-3.75 + 4.35 = 0.6

0.6 - 6.55 = - 5.95

- 3.75 + 4.35 - 6.55 = - 5.95

There is one input being mapped into two different outputs, so this is not a function. The correct option is D.

A function is a relation that maps elements from one set (the domain) into elements from another set (the range). Such that each element from the domain can be mapped into only one element from the range.

In this case, the table is:

So, the input "12" appears twice, the first time is mapped into 300 miles, and the second time is mapped into 350.

So the same value from the domain is being mapped into two different values of the range, meaning that this is not a function. So the correct option is D.

Answer:

36%

Step-by-step explanation:

Area of circle is

[tex]\pi {r}^{2} [/tex]

If the radius is decreased by 20%. Then the radius will be

80% of the original radius.

So our radius is 0.8.

So our area is

[tex]\pi(0.8r) {}^{2} [/tex]

[tex]\pi(0.64 {r}^{2} )[/tex]

Since pi is constant, the radius only really matters.

We went from

[tex]1 {r}^{2} [/tex]

to

[tex]0.64 {r}^{2} [/tex]

So our area will decrease by 36%

Proof: Let the radius be 10.

So the area of circle will be

[tex]\pi(10) {}^{2} = 100\pi[/tex]

Let our other radius is 8 because 8 is a 20% decrease of the orginal radius

[tex]\pi(8) {}^{2} = 64\pi[/tex]

Next, we subtract the area to find decrease in area

[tex]100\pi - 64\pi = 36\pi[/tex]

Since pi is constant, we can ignore it so our decrease in area is 36%

Answer:

Base 10 is always the decimal system which is from (0-9).

Using the normal distribution, it is found that P(X = 8) is equals to zero.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Hence, from the last bullet point, it is found that P(X = 8) is equals to zero.

Problem 3

A triangle cannot be constructed with these parameters.

----------------------------

Explanation:

Use the Law of Sines to find angle B

sin(A)/a = sin(B)/b

sin(120)/12 = sin(B)/13

sin(B) = 13*sin(120)/12

sin(B) = 0.93819419

B = arcsin(0.93819419) or B = 180 - arcsin(0.93819419)

B = 69.75047247 or B = 180 - 69.75047247

B = 69.75047247 or B = 110.24952753

These angle values are approximate.

-----------

If B = 69.75047247, then,

A+B+C = 180

C = 180 - (A+B)

C = 180 - (120 + 69.75047247)

C = -9.75047247000001

We get a negative result which isn't valid.

This means B = 69.75047247 isn't valid either.

-----------

If B = 110.24952753, then,

A+B+C = 180

C = 180 - (A+B)

C = 180 - (120 + 110.24952753)

C = -50.24952753

We get a similar conclusion here as well.

-----------

No matter what value of B we go with, we end up with a negative value for angle C.

Negative angles are not allowed.

Therefore, we cannot construct a triangle with sides a = 12, b = 13 and angleA = 120 degrees.

This is one example of an SSA triangle leading to no possible solutions. Refer to the SSA ambiguous case for more info.

-----------

Check out the diagram below. Imagine that point B can be anywhere on the dotted circle. Imagine it can rotate around as in an animation. This circle is centered at point C and has radius a = 12. No matter where point B is placed, we cannot get it to land on the horizontal line to therefore form a triangle. Simply put: side a = 12 is too short.

I used GeoGebra to make the diagram and make sure it's to scale. This is to visually verify that we cannot construct such a triangle with these parameters.

Answer:

Step-by-step explanation:

A rhombus is a quadrilateral where all four sides are equal and the opposite angles are equal.

3x - 4 = 3y + 8 = -2x - 9 = 39

The value of x is 43/3

The value of y is 31/3

The value of z is -24

A rhombus is a quadrilateral where all four sides are equal and the opposite angles are equal.

We have,

Rhombus:

All four sides are equal.

So,

3x - 4 = 3y + 8 = -2x - 9 = 39

Now,

3x - 4 = 39

3x = 39 + 4 = 43

3x = 43

x = 43/3

3y + 8 = 39

3y = 39 - 8

3y = 31

y = 31/3

-2z - 9 = 39

-2z = 39 + 9

-2z = 48

z = -24

Thus,

The value of x is 43/3

The value of y is 31/3

The value of z is -24

Answer:

828 in²

Step-by-step explanation:

To find the surface area of a triangular prism, you find the area of each side and add them together.

Find the area of each rectangular side:

Side 1 :  9 × 20 = 180 in²

Side 2 : 15 × 20 = 300 in²

Side 3 : 12 × 20 = 240 in²

Find the area of the triangular sides:

Area of a Triangle = [tex]\frac{1}{2}[/tex]bh

As you can see, 9 and 12 both work as the height/base for the triangular sides, so

Δ Side 1 = [tex]\frac{1}{2}[/tex]bh = [tex]\frac{1}{2}[/tex](9)(12) = 54

Δ Side 2 is also 54.

Add the areas of all the sides together:

180 + 300 + 240 + 54 + 54 = 828 in²
