Answer:

a)  $498

b) $1052

c) $554

Step-by-step explanation:

to find the median of lower half of data:  find median of all the data, then find middle value from the minimum value to the median (not including median)

to find the median of upper half of data:  find median of all the data, then find middle value from the median to the maximum value (not including median)

interquartile range (IQR) is the difference of the two

Answer:

a

Step-by-step explanation:

Answer:

you take 2 points on the graph

(3,300) and (6,200)

and then you do y2 -y1

                           x2-x1          

you plug in the values

200-300

6-3               =    -(100)/(3)

every 3 years the resale of a refrigerator decreases by 100 dollars.

its basically the rate that the price goes down for resale value of a refrigerator

Step-by-step explanation:

Let's take the points displayed on this graph:

(300, 3) (200, 6) and (100, 9).

Our first value in the points represents the amount of money for the resale value of a refrigerator, and the second value represents the number of years after the original purchase. So, as we can see, as the years increase, the value goes down $100 dollars every three years.

3 years after original purchase: $300

Increase years by three, value goes down by $100

6 years after original purchase: $200

The rate of change in this situation means that for every  resale three years after the original purchase, the value will decrease by $100.

First, order the number set from least to greatest:

3 , 4 , 4 , 7 , 8 , 9 , 12 , 14 , 16 , 20

Mean: You find the mean by combining all the terms, and dividing by the amount of the terms there are in the number set:

(3 + 4 + 4 + 7 + 8 + 9 + 12 + 14 + 16 + 20)/10

(97)/10 = 9.7

Mean: 9.7

Median: You find the median by first ordering the number set from least to greatest, and finding the middle number. Note that if there is a even number of numbers in the set, you find the mean with the two given median digits:

8 & 9 are the median numbers:

(8 + 9)/2 = (17)/2 = 8.5

Median: 8.5

Mode: The mode is the number(s) in the set that shows up the most:

Mode: 4 (shows up one more time than all other numbers)

Range:  The range can be found by subtracting the least number from the greatest number in the number set:

Range: 20 - 3 = 17

Range: 17

Answer:

C

Step-by-step explanation:

Radius: 12 / 2 = 6 m

Area: 6^2 x pi = 113 m^2

Answer:

c

Step-by-step explanation:

area = π · r²

to change the diameter to radius you just divide by 2

12/2=6 so the radius is 6

then we just plug 6 into r for the circle are formula

6²=36

36x3.14=113.04 so her best answer choice is c

Answer:

D

Step-by-step explanation:

3x+9+6=6

step 1 combine like terms

9+6=15

now we have

3x+15=6

step 2 subtract each side by 15

15-15 cancels out

6-15=-9

now we have

3x=-9

step 3 divide each side by 3

3/3 cancels out

-9/3=-3

x=-3

The reason it can also be -3 is because I I means absolute value and the absolute value of negative 3 is positive 3

Have a great day :D

Answer:

m > $380

Step-by-step explanation:

First, the math:

$500-$120= $380.

She still needs $380.

Her $380 still needed is less than m, which gives us the last answer the most logical.

I hope this helped! Have a nice day.

Step-by-step explanation:

Answer:

B) 114.511m^3

Step-by-step explanation:

Formula of a cylinder is πr^2 x h

r = radius (half of diameter)

h = height

Since it is 3/4 full you only do 3/4 of the height so- 0.75 x 9.60 which equals 7.2

Half of the diameter is 2.25. 2.25^2 = 5.0625.

The volume of the cylinder = 5.0625π x 7.2

By solving this, you will get approximately 114.511 m^3 as your answer.

Given:

The figure of a triangle DEF.

To find:

The coordinate of image of given triangle after reflection over y-axis.

Solution:

The vertices of given triangle are D(1,4), E(4,3), F(2,0).

If a figure is reflected over the y-axis, then the rule of reflection is

[tex](x,y)\to (-x,y)[/tex]

Using this rule, we get

[tex]D(1,4)\to D'(-1,4)[/tex]

[tex]E(4,3)\to E'(-4,3)[/tex]

[tex]F(2,0)\to F'(-2,0)[/tex]

Therefore, the coordinates of image are D'(-1,4), E'(-4,3) and F'(-2,0).

Step-by-step explanation:

We would apply the formula for exponential decay which is expressed as

A = P(1 - r/n)^ nt

Where

A represents the value after t years.

n represents the period for which the decrease in value is calculated

t represents the number of years.

P represents the value population.

r represents rate of decrease.

From the information given,

P = 23000

r = 8% = 8/100 = 0.08

n = 1

Therefore, the exponential decay function described in this situation is

A = 23000(1 - 0.08/n)1)^ 1 × t

A = 23000(0.92)^t

If A = 15000, then

15000 = 23000(0.92)^t

0.92^t = 15000/23000 = 0.6522

Taking log of both sides to base 10

Log 0.92^t = log 0.6522

tlog 0.92 = log 0.6522

- 0.036t = - 0.1856

t = - 0.1856/- 0.036

t = 5 years to the nearest year

Answer:

112*

Step-by-step explanation:

The easy way to figure this out is to take the two numbers we do have and add them together. 50 + 62 = 112

We now now the complete angle if that line was not there in the middle. and sice that angle is the same at angle X it is automatically the same, 112. If you don't understand please comment and let me know.

Answer:

46 minutes

Step-by-step explanation:

Number of questions = 23

Time taken per question = 2 minutes

The longest time available to finish all questions :

Longest time will be ; if one spends all two minutes on each question ;

Then ;

Longest time = number of question * maximum time per question

Longest time = 23 * 2 = 46 minutes

Answer:

x = 9 (it is seriously not drawn to scale)

Step-by-step explanation:

BC = DC^2 + BD^2 (Pythagorean theorem)

BC = 4^2 + 6^2

BC = 16 + 36

BC = 52^2

BC = 2sqrt13

BC/AB = DC/BD

(2sqrt13)/AB = 4/6

6(2sqrt13) = 4(AB)

12sqrt13 = 4AB

3sqrt13 = AB

AC^2 = AB^2 + BC^2 (Pythagorean Theorem)

AC^2 = (3sqrt13)^2 + (2sqrt13)^2

AC^2 = 117 + 52

AC^2 = 169

AC = 13  

AD + DC = AC

AD + 4= 13

AD = 9
