Answer:
(a) median = 6
(b) median = 14
(c) median = 37
(d) median = 19
(e) median = 4.5
(f) median = 15
(g) median = 126
(h) median = 345
(i) median = 50
(j) median = 75
Step-by-step explanation:
The median of the ungrouped data is obtained by arranging the numbers from the lowest to the highest number, then select the middle number. If you have two numbers in the middle, sum the two numbers and divide it by 2.
(a) in order: 3 4 4 6 7 8 8
median = 6
(b) in order: 11 11 12 14 15 16 17
median = 14
(c) in order: 31 31 34 37 38 41 42
median = 37
(d) in order: 17 17 18 19 19 21 23
median = 19
(e) in order: 3 3 3 4 5 6 7 9
median = (4 + 5) / 2 = 4.5
(f) in order: 12 14 14 14 16 18 19 20
median = (14 + 16)/2 = 15
(g) in order: 120 121 124 128 129 131
median = (124 + 128)/2 = 126
(h) in order: 321 339 342 345 352 358 362
median = 345
(i) in order: 43 46 49 49 51 51 51 52
median = (49 + 51)/2 = 50
(j) in order: 68 70 73 74 76 77 77 81
median = (74 + 76)/2 = 75

A steel ball is dropped from a height and hits the ground 6.7 seconds after its release. From what height (in feet) was the ball released?
Step-by-step explanation:
Acceleration = g = 32.17ft/s²
Initial velocity = 0ft/s
Time taken = 6.7s
Using Kinematics,
we have s = ut + 0.5at².
=> s = (0)(6.7) + 0.5(32.17)(6.7)²
=> s = 722.06ft.

sorry if thats wrong.
Answer:
46
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, subtract 8 from both sides of the equation:
2x + 8 (-8) = 16 (-8)
2x = 16 - 8
2x = 8
Next, divide 2 from both sides of the equation:
(2x)/2 = (8)/2
x = 8/2 = 4
Next, plug in 4 for x in the given expression:
x + 42
(4) + 42 = 46
46 is your answer.

Describe two different ways you could find measure of CFD. What is the measure of
this angle?
Answer:
∠CFD = 60°
Step-by-step explanation:
Along line CE:
∠AFE + ∠AFB + ∠BFC = 180° (sum of angles on a straight line)
(7x + 4) + (8x + 6) + (6x + 2) = 180
collecting alike terms:
7x + 8x + 6x + 4 + 6 + 2 = 180
21x + 12 = 180
21x = 168
x = 8°
We could find the measure of CFD using:
a) Along line AD:
∠AFB + ∠BFC + ∠CFD = 180° (sum of angles on a straight line).
(8x + 6) + (6x + 2) + ∠CFD = 180
14x + 8 + ∠CFD = 180
∠CFD = `180 - (14x + 8)
∠CFD = 172 - 14x
b) ∠CFD = ∠AFE (vertical opposite angles are equal)
∠CFD = 7x + 4
To find value of ∠CFD, substitute x = 8
∠CFD = 7(8) + 4
∠CFD = 60°

Step-by-step explanation:
Increase 386.3 by 4%
Given:
Increase 386.3 by 4%.
To find:
The value for given statement.
Solution:
We have,
Initial value = 386.3
Increasing rate = 4%
The increased value is
[tex]\text{New value}=\text{Initial value + Increasing rate }\times \text{Initial value}[/tex]
[tex]\text{New value}=386.3+\dfrac{4}{100}\times 386.3[/tex]
[tex]\text{New value}=386.3+15.452 [/tex]
[tex]\text{New value}=401.752[/tex]
Therefore, the required value is 401.752.

Please help! The expressions 3x - 9 and 23 - 5x represent the lengths (in feet) of two sides of an equilateral triangle. Find the length of a side. Show your work.
We are dealing with an equilateral triangle which has 3 equal sides.
length of a side = 3 ft
Since the three sides of an equilateral triangle are equal and we are given two sides to have lengths of 3x - 9 and 23 - 5x , it means that;
3x - 9 = 23 - 5x
Rearranging this gives;
3x + 5x = 23 + 9
8x = 32
x = 32/8
x = 4
putting 4 for x in 3x - 9, we have;
3(4) - 9 = 3 ft
Thus,
length of a side = 3 ft

if angle KLJ~angle VWU. Find the x value
Answer:
17
Step-by-step explanation:
Since angle KLJ~angle VWU are similar :
KL / WV = KJ/ UV
(25 / 20) = (4x - 23 / 2x + 2)
Cross multiply :
25(2x + 2) = 20(4x - 23)
50x + 50 = 80x - 460
50x - 80x = - 460 - 50
-30x = -510
x = 510 / 30
x = 17

Based on the data table provided below, how many people would we expect to pick a snake as their favorite animal if 440 people were asked their preferences?
Favorite Animal Number
Panda 13
Snake 10
Tiger 17
Dolphin 15
Options:
1.) 80
2.) 120
3.) 136
4.) 104
Answer:
104
Step-by-step explanation:
first get the sum of the data given, 13+10+15+17= 55
now get the percentage of ppl that prefer snakes, (13/55) x 100
that would be 23.63%
multiply the percentage to 440 the answer would be 103.972
if rounded off to the nearest whole number it would be 104

The population of a small town was 3500 in 2005. The population increases by 4% annually. A. Write an exponential growth function to represent this situation. B. What will the population be in 2025?
Answer: The population in 2025 will be 7669
Step-by-step explanation:
a) When we have an initial quantity A, and we have an increase of the X%, the new quantity is written as:
new quantity = A + A*(X%/100%) = A*(1 + X%/100%)
In this case, our initial quantity is 3500, the town's population in 2005.
And X% = 4%.
We know that each year, the population increases by 4%.
Then if P(1) is the population one year after 2005, this is:
P(1) = 3500*(1 + 4%/100%) = 3500*(1.04)
After another year, the population increases again:
P(2) = (3500*(1.04))*(1 + 4%/100%)) = 3500*(1.04)*(1.04) = 3500*(1.04)^2
Well, we already can see the pattern here, the population N years after 2005 will be:
P(N) = 3500*(1.04)^N
b) Now we want to know the population in 2025.
N represents the number of years after 2005, then we will have:
N = 2025 - 2005 = 20
2025 is 20 years after 2005.
Then the population in 2025 will be:
P(20) = 3500*(1.04)^20 = 7,668.9
And we can not have a 0.9 of a person, so we should round it up to the next whole number, then the population in 2025 will be 7669
