Answer:
The medians of all three teams can show the overall skill level of the teams. For example, the medians only vary between 47 and 48. This can show that most team members have around the same experience (since they have around the same median). The red team was the best in terms of time, but they don't vary much from their opposing teams.
Step-by-step explanation:
(Can also add more references to the chart and rank the teams in term of time )

Question 3 (2 points)
(04.07)
Two separate bacteria populations grow each month and are represented by the functions fx) = 3* and g(x) = 7x + 6. In what month is the f(x)
population greater than the g(x) population? (2 points)
Complete question is;
Two separate bacteria populations grow each month and are represented by the functions f(x) = 3^(x) and g(x) = 7x + 6. In what month is the f(x) population greater than the g(x) population?
A. Month 1
B. Month 2
C. Month 3.
D. Month 4
Answer:
Option D: Month 4
Step-by-step explanation:
We are given the functions;
f(x) = 3^(x)
And g(x) = 7x + 6
We want to find the month when f(x) > g(x)
Thus;
3^(x) > 7x + 6
For option A, month 1 means x = 1.thus;
LHS is 3¹ = 3
RHS = 7(1) + 6 = 13
Our LHS is not greater than RHS as the question demands, thus this option is not correct
For option B, month 2 means x = 2. thus;
LHS is 3² = 9
RHS = 7(2) + 6 = 20
Our LHS is not greater than RHS as the question demands, thus this option is not correct
For option C, month 3 means x = 3. thus;
LHS is 3³ = 27
RHS = 7(3) + 6 = 27
Our LHS IS equal to the RHS and not greater than RHS as the question demands, thus this option is not correct
For option D, month 4 means x = 4. thus;
LHS is 3⁴ = 81
RHS = 7(4) + 6 = 34
Our LHS is greater than RHS as the question demands, thus this option is correct

Answer:
x = 16√3
y = 8√3
z = 24
Step-by-step explanation:
From the figure attached,
By applying cosine rule in ΔABD,
cos(45°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{\sqrt{2} }=\frac{z}{24\sqrt{2} }[/tex]
z = 24
By applying sine rule in ΔABD,
sin (45°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{\sqrt{2} }=\frac{AD}{24\sqrt{2} }[/tex]
AD = 24
By tangent rule in ΔADC,
tan(60)° = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
[tex]\sqrt{3}=\frac{AD}{DC}[/tex]
[tex]\sqrt{3}=\frac{24}{y}[/tex]
y = 8√3
Similarly, by sine rule in ΔADC,
sin(60°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3} }{2}= \frac{AD}{AC}[/tex]
[tex]\frac{\sqrt{3} }{2}= \frac{24}{AC}[/tex]
AC = 16√3
x = 16√3

Step-by-step explanation:
Scientists are drilling a hole in the ocean floor to learn more about the Earth's history Currently, the hole is in
the shape of a cylinder whose volume is approximately 4200 cubic feet and whose height is 4.3 miles. Find
the radius of the hole to the nearest hundredth of a foot. (Hint: Make sure the same units of measurement are
used.)
The radius of the hole is
feet. (Round to the nearest hundredth.)
Answer:
The radius of the hole is 0.24 feet
Step-by-step explanation:
Firstly, we need to convert the miles to feet
Mathematically;
1 mile = 5,280 feet
4.3 miles is thus;
4.3 * 5,280 = 22,704 feet
Mathematically, the volume of a cylinder is;
V = pi * r^2 * h
here, we want to get r
4200 = 3.142 * r^2 * 22,704
r^2 = 4200/(3.142 * 22,704)
r = 0.24 feet
Solve for x. Round your answer to 2 decimal places.
Answer:
93.99
Step-by-step explanation:
sin rule is:
sin A ÷ a = sin B ÷ b = sin C ÷ c
A B C are angles
a b c are the lengths opposite to each angle
to find angle opposite to x:
180- (90+57) = 33°
180: sum of angles in a traingle
90: since its a right angle traingle
to find x:
sin 57 ÷ 41 = sin 33 ÷ x
rearrange:
x= (sin 33 x 41) ÷ sin 57
x= 93.99 (2 d.p/2 decimal places)

X^2 + 4x - 7x = 0
GIVE YOUR ANSWER TO THE CORRECT 2 DECIMAL PLACES
Answer:
x ≈ - 5.32, x ≈ 1.32
Step-by-step explanation:
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ± [tex]\sqrt{11}[/tex] ( subtract 2 from both sides )
x = - 2 ± [tex]\sqrt{11}[/tex]
Thus
x = - 2 - [tex]\sqrt{11}[/tex] ≈ - 5.32 ( to 2 dec. places )
x = - 2 + [tex]\sqrt{11}[/tex] ≈ 1.32 ( to 2 dec. places )
Answer:
x = -5.32, x = 1.32
Step-by-step explanation:
Ok. So to use the Complete the Square method, you divide the middle value by 2 and then square the number you get. This will give:
[tex](x^{2} + 4x + (\frac{4}{2}) ^2) - (\frac{4}{2}) ^2 -7 = 0[/tex]
[tex](x^{2} + 4x + 4) - 4 -7 = 0[/tex]
[tex](x^{2} + 4x + 4) - 11 = 0[/tex]
[tex](x^{2} + 4x + 4) = 11[/tex] (now factor the left side)
[tex](x + 2)(x + 2) = 11[/tex]
[tex](x + 2)^{2} = 11[/tex] (now square root both sides)
[tex]\sqrt{(x + 2)^{2}} = \sqrt{11}[/tex]
[tex]x + 2 = \sqrt{11}[/tex]
[tex]x = - 2 +/- \sqrt{11}[/tex] (+/- = plus or minus)
x = -5.32, x = 1.32

Answer:
x = 11, arc RB = 150°
Step-by-step explanation:
The secant- secant angle RDB is calculated as half the difference of its intercepted arcs, that is
∠ RDB = [tex]\frac{1}{2}[/tex] ( RB - EC ), that is
5x - 10 = [tex]\frac{1}{2}[/tex] ( 13x + 7 - 60 )
Multiply both sides by 2 to clear the fraction
10x - 20 = 13x - 53 ( subtract 13x from both sides )
- 3x - 20 = - 53 ( add 20 to both sides )
- 3x = - 33 ( divide both sides by - 3 )
x = 11
Thus
arc RB = 13x + 7 = 13(11) + 7 = 143 + 7 = 150°

The four walls and the ceiling of a cubical room need to be painted. If the height of the room is 4 m , and painting costs ₹ 20/m2 20 / m 2 , what is the total cost of painting the room?
Answer:
₹ 1920
Step-by-step explanation:
Since the room is cubical in nature, we will find the total surface area of the room
Total surface area of the cubical room = 6L²
L is the length of one side of the room
Given
L = 4m
Total surface area of the cubical room = 6(4)²
Total surface area of the cubical room = 6×16
Total surface area of the cubical room = 96m²
If the painting costs ₹ 20/m², this means;
₹ 20 = 1m²
For the total room:
x = 96m²
Divide both expressions
20/x = 1/96
x = 20×96
x = 1920
Hence the total cost of painting the room ₹ 1920

Answer: Choice C [tex]-3x+2y \ge 7[/tex]
===================================================
Explanation:
The boundary line is solid, so that means we'll be dealing with "or equal to" as part of the inequality sign. The answer is between choice A and choice C because of this.
Note how the point (0,0) is not in the shaded region. This must mean that plugging x = 0 and y = 0 into the answer will lead to a false statement.
If we plug x = 0 and y = 0 into choice A, then we get...
[tex]3x-2y \le 7\\\\3(0)-2(0) \le 7\\\\0 \le 7\\\\[/tex]
Which is a true statement, implying that (0,0) is in the shaded region. However, we're after a false statement, so we can rule out choice A.
The answer must be choice C
Let's plug (x,y) = (0,0) into choice C
[tex]-3x + 2y \ge 7\\\\-3(0) + 2(0) \ge 7\\\\0 \ge 7\\\\[/tex]
That is false because 0 is not equal to 7, nor is it larger than 7.
This helps confirm that choice C is the answer.

What is the value of arccos(sin(5pi/4))
Step-by-step explanation:
arccos(sin(5π/4))
= arccos(sin(-π/4))
= arccos(-√2/2)
= 3π/4.
The value of trigonometric function arccos(sin(5π/4)), π/4
What is trigonometry?Trigonometry is a branch of mathematics, which deals with the study of right angle triangles. Trigonometry is concerned with specified functions of angles and their applications to calculations.
There are 6 commonly used functions in trigonometry with their name and abbreviations-
sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), cosecant (cosec)
First, we can use the trigonometric identity sin(θ) = cos(π/2 - θ) to rewrite this expression:
sin(5π/4) = cos(π/2 - 5π/4)
Next, we can use the fact that cos(x) is an increasing function on the interval [0, π], so cos(x) is unique on this interval for each value of x.
This means that the inverse cosine function, arccos, is also unique on the interval [0, π].
Therefore, we can conclude that:
0 ≤ π/2 - 5π/4 ≤ π
arccos(sin(5π/4)) = π/2 - 5π/4 = π/4.
So the answer is π/4 in radians.

If Summer (starting from rest) runs from the 20 m mark to the 35 m mark with an acceleration of 5 m/s². then 12.25 m/s is the final velocity.
What is Velocity?Velocity is the distance covered by an object in unit time.
Given that,
Summer (starting from rest) runs from the 20 m mark to the 35 m mark with an acceleration of 5 m/s²
a=0.5 m/s²
s is distance=35-20=15
We have a formula with velocity, acceleration and distance
Now v²=2as
Here v is velocity=2
a is acceleration=5
s is the distance.=15
v²=2×5×15
The multiplication value of 2×5×15 is 150.
v²=150
Take square root on both sides
v=√150
v=12.25 m/s
Therefore final velocity is 12.25m/s.
