What is the median for the data set? 15, 17, 8, 23, 14
15 38.5 8 15.4

Answers

Step-by-step explanation:

Add all the data and divide by 2 to get your median

The median of the data set 8, 8, 14, 15, 15, 15.4, 17, 23, 38.5 will be 15.

What is a median?

The median of the data is the middle value of the data which is also known as the central tendency of the data and is known as the median.

The data set is given below.

17, 8, 23, 14, 15, 38.5, 8, 15.4

Arrange the data in ascending order, then we have

8, 8, 14, 15, 15, 15.4, 17, 23, 38.5

The number of the term will be 9, then the median will be

Median = (n + 1) / 2

Median = (9 + 1) / 2

Median = 10 / 2

Median = 5th term

5th term that is 15.

The median of the data set 8, 8, 14, 15, 15, 15.4, 17, 23, 38.5 will be 15.

The value of a car depreciates every year. Suppose you buy a new car for $17,000, and each year its value is only 90% of what it was the previous year. Write an equation that represents the value of the car, y, after x years.


A.
y=0.90 · 17,000xy equals 0.90 times 17,000 superscript x baseline


B.
y=17,000 · 0.90xy equals 17,000 times 0.90 superscript x baseline


C.
y=17,000 · 0.10xy equals 17,000 times 0.10 superscript x baseline

Answers

B.

y=17,000 · 0.90xy equals 17,000 times 0.90 superscript x baseline

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Since the car’s initial value was $17,000, a = 17,000. Since the car retains 90% of its value each year, b = 0.90.

Answer:

Step-by-step explanation:

Prinkpal balance = $24^4^6% =5.76

The principle amount will be equal to $100. The correct option is B.

What is simple interest?

The straightforward crediting of cash flows related to an investment or deposit is referred to as "simple" interest. Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest.

Given that Imani earned $24 in interest after four years on an account that paid 6% simple interest annually.

The principle amount will be calculated by using the simple interest formula.

SI = ( P x R x T ) / 100

24 = ( P x 0.06 x 4 )

P = 24 / ( 0.06 x 4 )

P = $100

Therefore, the principle amount will be equal to $100. The correct option is B.

Find the distance between each pair of points (2, -6) and (7, -2)

Answers

Answer:

6.4 units

Step-by-step explanation:

The points plotted on a graph forms a right-angle triangle parallel with the x-axis. The hypotenuse is the direct distance between the points. So

a**2 + b**2 = c**2 where a is the x difference and b is the y difference

(2 -7)**2 + (-6 -(-2))**2 = c**2

-5**2 + -4**2 = c**2

25 + 16 = c**2

41 = c**2

41**(1/2) = (c**2)**(1/2)   and ignore the negative because they're lengths

i would really appreciate it if you'd help me

Answers

Answer:

1.) x = 150

2.) x = 8.5

Step-by-step explanation:

1.)

[tex]\frac{x}{5}+10=40\\\\\frac{x}{5}=30\\\\x=150[/tex]

2.)

[tex]4x-36=-2\\\\4x=34\\\\x=8.5[/tex]

Answer:

1. x = 150

2. x = 8.5

Step-by-step explanation:

1. x/5 + 10 = 40

Get x by itself and then solve for x.

First, subtract 10 from both sides

x/5 + 10 - 10 = 40 - 10

x/5 = 30

Then, multiply by 5 to get x by itself.

x/5 = 30

x/5 * 5 = 30 * 5

x = 150

2. 4x - 36 = -2

Get x by itself and then solve for x.

First, add 36 to both sides

4x - 36 + 36 = -2 + 36

4x = 34

Then, Divide each side by 4

4x/4 = 34/4

x = 8.5

Answers

Answer:

27 ft^2

Step-by-step explanation:

r = 3 ft (that's the radius)

and pi = 3

A = pi r^2

or

3 * r^2

plug in r = 3

so 3 * 3^2 = 3 * 9 = 27 ft^2

(note: 3^2 = 3 * 3. Squaring means we multiply the number by itself)

Your radius (r) =3ft

A=pi•r^2
A=3.14•3^2
A=3.14•9
A=28.26

2(x-8) + 4x = 6(x - 2) - 4

Answers

Answer:

They are equal.

Step-by-step explanation:

2(x-8)+4x=6(x-2)-4

Distribute: 2(2•x-2•8)+4x=6(6•x-6•2)-4

2x-16+4x=6x-12-4

Combine Like-Terms: (2x+4x)-16=(-12-4)6x

6x-16=6x-16

Since both sides are equivalent, all numbers are solutions.

The equation 2(x - 8) + 4x = 6(x - 2) - 4 is -16 = -16 which means that

the equation has infinitely many solutions.

We have,

Let's solve the given equation step by step:

2(x - 8) + 4x = 6(x - 2) - 4

Distribute on both sides of the equation:

2x - 16 + 4x = 6x - 12 - 4

Combine like terms on both sides:

6x - 16 = 6x - 16

Subtract 6x from both sides to isolate the constants:

-16 = -16

The equation -16 = -16 is true, which means the given equation is an identity.

This implies that the original equation is true for all values of x; there is no specific value of x that satisfies it.

Therefore,

The equation has infinitely many solutions.
