3. Mary is a real estate agent. One month she sold 7 houses at these prices: $171 000, $165 000, $178 000, $161 000, $174 000, $168 000, $240 000

3.a) What is the median price of the houses she sold?

3.b) Do you think the mean price is greater than or less than the median price of the houses sold that month? Why?


3.c) Which average do you think better represents a typical price of houses she sold that month? Why?

Answers

Answer 1

The median price of the houses sold will be equal to $171000 and yes, the mean price is greater than the median price of the houses.

What is Mean?

Mean in mathematics is a quantity that falls somewhere between the extremes of a set. There are different types of meanings, and how they are calculated relies on the connection that is known about or is believed to control the other members.

a.

The median of given prices will be,

Let's arrange the given prices in ascending order,

161000, $165000, $168000, $171000, $174000, $178000, $240000

Then, the middle term is the median,

So, median = $171000

b.

Number of terms = 7

The mean of the given prices will be,

(171000 + 165000 + 178000 + 161000 + 174000 + 168000 +240000)/7

= 1257000/7

Mean = 179571.4286

Comparing mean and median, the mean price is greater than the median.

radius of a cone with a volume of 100.48 yds3 and a height of 6 yds

Answers

Answer:

r = 4

Step-by-step explanation:

Volume of a cone:

V = πr²(h/3)

Given:

V = 100.48

h = 6

π = 3.14

Work:

V = πr²(h/3)

100.48 = r²(3.14)(6/3)

100.48 = r²(3.14)(2)

100.48 = r²6.28

r² = 100.48/6.28

r² = 16

After 7 years, how much more money would Riley have in her account than Ryan, to the nearest dollar?

Answers

Answer: 257

257 in delta math

Step-by-step explanation:

After 7 years, Riley would $441.5 more have in her account than Ryan.

What is compound interest?

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

Given that Riley invested $5,100 in an account paying an interest rate of [tex]7\tfrac{3}{4}[/tex]% compounded quarterly. Ryan invested $5,100 in an account paying an interest rate of [tex]7\tfrac{1}{4}[/tex] % compounded daily, we need to find that after 7 years how much more money would Riley have in her account than Ryan,

[tex]A = P(1+r/n)^{nt[/tex]

Where A = amount

P = principal

r = rate

n = number of times the amount is compounded and t = time

Riley = compounded quarterly,

[tex]A = P (1 + r / 4)^{4t[/tex]

[tex]A = 5100(1+0.019375)^{4(7)}\\\\A = 5100(1.019375)^{28}\\\\\\[/tex]

[tex]A = 8728.13[/tex]

Therefore, in 7 years Riley has $8728.13.

Ryan = compounded daily,

[tex]A = P (1 + r / 365)^{365t[/tex]

[tex]A = 5100(1 + 0.00019)^{356(7)}\\\\A = 5100(1.00019)^{2555}\\\\A = 8286.64[/tex]

Therefore, in 7 years Ryan has $8286.64.

Riley will have $441.5 more.

Hence after 7 years, Riley would $441.5 more have in her account than Ryan.

A line passes through the points (-1, 4) and (3, -8). A second line passes through
(-1,8) and (2, 11).
A) Write the equation of each line. Show all work.

Answers

Answer:

y = -3x + 1,  y = x + 9

Step-by-step explanation:

An equation consists of a slope and the y-intercept. To find the slope, you need to plug the values into the slope formula.

y2 - y1/ x2 - x1

= -8 - 4/ 3 - (-1)

= -12/ 4

= -3

The slope of the first line is -3.

To find the y-intercept, you need to plug in either one of the coordinates into the equation, y = -3x + b

-8 = -3(3) + b

-8 = -9 + b

1 = b

The equation, for the first one, is y = -3x + 1  

Line 2:

11 - 8/ 2 - (-1)

= 1

y = 1x + b

11 = 1(2) + b

11 = 2 + b

9 = b

y = x + 9

In a robotics competition, a robot must be built with a specific
maximum starting height, width, and depth. In order to meet the
height requirements, a robot must fit in the judge's plexi-glass box.
The box is a rectangular prism that has a surface area of 1 728 in”, a
width of 15 inches, and a length of 18 inches. The Mad Hatter robot
is 17.75 inches tall in its starting position. Does the Mad Hatter
meet the height requirement?

Answers

L = 18, W = 15 and H = ?
2*(15+18) + 2*(15H) + 2*(18H) = 540 + 30H + 36H
1,728 - 540 = 66H
1,188/66 = H = 18
so yes, it meets the height requirement 17.75 is less than 18

PEMDAS is an acronym that refers to the sequence of operations to be employed when solving equations with multiple operations. PEMDAS is an acronym that stands for P-Parenthesis, E-Exponents, M-Multiplication, D-Division, A-Addition, and S-Subtraction.

The given mathematical expressions can be solved as shown below.

1 + 5 · 2 + (1 + 3)²

Step1: Solving Parenthesis first,

= 1 + 5 · 2 + (4)²

Step2: Exponents,

= 1 + 5 · 2 + 16

Step3: Multiplication,

= 1 + 10 + 16

Step4: Addition,

= 27

4 + 8[(1/4) + 2]

Step1: Parenthesis

= 4 + 8(2.25)

Step2: Multiplication,

= 4 + 18

Step3: Addition,

= 22

0.25 · 4³ - 1

Step1: Exponents,

= 0.25 · 64 - 1

Step2: Multiplication,

= 16 - 1

Step3: Subtraction,
