Step-by-step explanation:
First organize the data from least to greatest. 3,3,4,5,6,7,7,7,8
To find the median, remove the extremes from the data over and over.
3,4,5,6,7,7,7

Answer:
3/5 or 0.6
Step-by-step explanation:
Here, given the value of tan theta , we want to find the value of sine theta
Mathematically;
tan theta = 0pposite/adjacent
Sine theta = opposite/hypotenuse
Firstly we need the length of the hypotenuse
This can be obtained using the Pythagoras’ theorem which states that the square of the hypotenuse equals sum of the squares of the two other sides.
Let’s call the hypotenuse h
h^2 = 3^2 + 4^2
h^2 = 9 + 16
h^2 = 25
h = √(25)
h = 5
Now from the tan theta, we know that the opposite is 3
Thus, the value of the sine theta = 3/5 or simply 0.6

PLEASE HELP ME WITH THIS QUESTION :0
Today there are 3,431 thousand elementary and secondary teachers employed in a certain country. This number is expected to increase to 3,732 thousand teachers by the next decade. What is the percent increase?
A = old value = 3431
B = new value = 3732
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (3732-3431)/3431 ] * 100%
C = (301/3431) * 100%
C = 0.0877 * 100%
C = 8.77%
Answer: Roughly an 8.77% increaseNote: if C was a negative value, then we'd have a percentage decrease

A.4,5,8
b. 5,5,7
c. 6,6,14
d. 7,7,15
Answer:
C
Step-by-step explanation:
That would be an isosceles triangle, therefore, acute. All angles measure 60, therefore being acute. I'm not 100% sure though.

Please can somebody work out the mean? I'm struggling! <3
Step-by-step explanation:
The formulae for median is
N=£f/2 that is the sum of frequency divide by two
Median =Nth term + (N + 1)th term divide by two
first of all do the cumulative frequency which is
2+0=2
2+8=10
10+4=14
14+10=24
24+6=30
therefore N=£f/2
N=30/2
=15
when you use the formulae
it will be 15+(15+1)/2
then check the cumulative frequency the value close to the range of 15 and 16 which is 14
then you trace 14 back to the conceded goals
which is 2
then you add 2+2 and divide by two
which is= 2
therefore the median is 2
Mean
formulae
mean=conceded goals multiply by the frequency/sum of frequency
0*2=0.
1*8=8
2*4=8
3*10=30
4*6=24
total is 70
sum of frequency is 10
according to the formulae 70/10=7
therefore the mean is 7
6z^6-21z^4-12z^2
give in step by step explanation
This expression cannot be simplified, as you cannot add or subtract variables raised to different exponents.
Answer:
Step-by-step explanation:
6z⁶ - 21z⁴ - 12z² = 2*3*z⁶ - 3*7*z⁴ - 4*3*z²
= 3z² (2z⁴ - 7z² - 4)
The polynomial 6x2 + x − 15 has a factor of 2x − 3. What is the other factor? A. 3x − 5 B. 3x + 5 C. 4x − 5 D. 4x + 5
Answer:
B: 3x+5
Step-by-step explanation:
You can solve this equation by doing the following steps:
6x2 + x - 15 is your polynomial. So take your polynomial and factor it down.
6x^2 + x - 15 = 6x^2 - 9x + 10x - 15 = 3x(2x - 3) + 5(2x - 3) = (3x+5)(2x - 3).
Check your answers again.
A) 3x - 5
Would this be possible considering our last answer? Which was (3x + 5)(2x - 3). No, it's not adding, so it's wrong.
B) 3x + 5
Could this be possible? Yes, it could because it has the first half of our answer. (3x + 5), keep this in mind.
C) 4x - 5
There was no 4 in the last part, so no. It's wrong. We're working with 2, 3, and 5 only. No 4.
D) 4x + 5
Again, no 4. Make sure to double-check your answers before clicking.
The answer is B) 3x + 5. Hope you found this helpful! Have a wonderful day and stay safe! (/O^O)/ *HELPPPPPP ASAP!!!!!!!!!!!!!!!!!!!!!!! PLS DO NOT LOOK IT UP
Answer:
The constant proportionality of the table above is 16.
Step-by-step explanation:
In order to solve this problem, you must divide the weight of cat food by the number of bags. You must also continue doing this for each of the ratios shown in the table.
64 ÷ 4 = 16
80 ÷ 5 = 16
96 ÷ 6 = 16
So, the proportionality of the table is 16. As you can see, when we divided the numbers, they all had a quotient of 16, which is our proportion.

Step-by-step explanation:
If A=2+i, O=-4, P=-i, and S=2+4i, find A-O+P+S.
==================================================
Work Shown:
A = 2+i
O = -4, this is the letter 'oh' not to be confused with the number zero
P = -i
S = 2+4i
A-O+P+S = (2+i) - (-4) + (-i) + (2+4i)
A-O+P+S = (2+i) + 4 + (-i) + (2+4i)
A-O+P+S = (2+4+2) + (i-i+4i)
A-O+P+S = 8+4i

Need help finding the value of Z
Answer:
4√7
Step-by-step explanation:
hyp1(9)/alt(x)=hyp2(7)/alt(x)
By cross multiplication, x^2 = 63
thus, alt = √63
Then, with Pythagorean theorem, (√63) ^ 2 + 7 ^ 2 = z ^ 2
Thus, 63 + 49 = z ^ 2
Thus, 112 = z ^ 2
Thus, z = √112
Thus, z = 4 √7

Given: Triangle ACD is isosceles; <1 is congruent to <3 Prove: Segment AB || Segment CD
Answer:
Segment AB || Segment CD
Step-by-step explanation:
Two lines are said to be parallel (||) if they do not meet, even when extended to infinity.
Given: <1 ≅ <3, ΔACD is an isosceles triangle.
Proof: Segment AB || Segment CD
From the diagram given,
AC ≅ AD (side property of isosceles triangle)
<3 = <4 (base angle property of an isosceles triangle)
<1 = <4 (alternate angle property)
Therefore, segment AB is parallel to segment CD.

Q. ε = {x: 2 ≤ x ≤30, x is an integer}, M = {even numbers}, P = {prime numbers}, T = {odd numbers} Find: (i) MUP (ii) M - T (iii) P∪(M∩T) (iv) P’U(M∩T’)
Answer:
(i)[tex]M \cup P=\{2,3,4,5,6,7,8,10,11,12,13,14,16,17,18,19,20,22,23,24,26,28,29,30\}[/tex]
(ii)M-T={2,4,6,8,10,12,14,16,18,20,22,24,26,28,30}

Step-by-step explanation:
Given the sets:
ε = {x: 2 ≤ x ≤30, x is an integer}
M = {even numbers}={2,4,6,8,10,12,14,16,18,20,22,24,26,28,30}
P = {prime numbers}={2, 3, 5, 7, 11, 13, 17, 19, 23, 29}
T = {odd numbers} ={3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29}
(i)This is the union of sets M and P. (Do not repeat same elemnts)
[tex]M \cup P=\{2,3,4,5,6,7,8,10,11,12,13,14,16,17,18,19,20,22,23,24,26,28,29,30\}[/tex]
(ii)M-T: This is the set M less elements in set T.
Since [tex]M \cap T =\{\}[/tex], the set M-T=M.
M-T={2,4,6,8,10,12,14,16,18,20,22,24,26,28,30}
(iii) P∪(M∩T)
[tex]M \cap T =\{\}[/tex]
Therefore:
P∪(M∩T) = P
P∪(M∩T) = {2, 3, 5, 7, 11, 13, 17, 19, 23, 29}
(iv) P’U(M∩T’)
Since T is the set of odd numbers, its complement will be the set of even numbers.
T'=M={2,4,6,8,10,12,14,16,18,20,22,24,26,28,30}
M∩T’=M={2,4,6,8,10,12,14,16,18,20,22,24,26,28,30}
[tex]P' =\{4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30\}[/tex]
Therefore:
P’U(M∩T’) = {4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30} U {2,4,6,8,10,12,14,16,18,20,22,24,26,28,30}

Two ships are located 200 m and 300 m respectively from a lighthouse. If the angle formed by their paths to the lighthouse is 96°. What is the distance between the two ships?
Answer:its from applications of trignometry
The distance between the two ships is 377.54 m.
Given that, two ships are located 200 m and 300 m respectively from a lighthouse and the angle formed by their paths to the lighthouse is 96°.
We need to find the distance between the two ships.
What is the cosine rule to find the side?The cosine rule is c²=a²+b²-2abcosC
Now, c²=200²+300²-2×200×300cos96°
⇒c²=40000+90000-1,20,000×(-0.1045)
⇒c²=40000+90000+12,540
⇒c=377.54 m
Therefore, the distance between the two ships is 377.54 m.

here is a question :D
Answer:
a) 1 : 4
b) 60 : 180 or 1 : 3
Step-by-step explanation:
Answer:
a. 1:4
b. 1:3
Step-by-step explanation:
Let’s start with a.
So the ratio 14:56 can be divided in two to 7:28 and they are both divisible by 7 we its most simplified form is 1:4 because 28/7 is 4 and 7/7 is 1.
Now for b.
So if 240 were sold in total and 180 of them were online them doing 240-180, 60 of them were sold in person so the ratio is 60:180 which can be simplified to 30:90 to 15:45 to 3:9 to 1:3.

Answer: B) 6
Step-by-step explanation:
First let's distribute the left side of the equation.
k - 16 + 4k = -2(2k -1) + 6k
Then let's combine like terms on the left side of the equation.
5k - 16 = -2(2k - 1) + 6k
Then let's distribute the right side of the equation.
5k - 16 = -4k + 2 + 6k
Then let's combine like terms on the right side of the equation.
5k - 16 = 2k + 2
Then let's move all the x's to one side, and all the constants to the other.
3k = 18
Then divide both sides of the equation by 3.
k = 6

Answer:

I promise I will mark as brainiest How many minutes is it before 12 noon, if 48 minutes ago it was twice as many minutes past 9 a.m.? i want step by step explanation
Answer:
9:00 am -------------------- 12:00pm ( There are 180 minutes between them)
Go 48 minutes back (132 Minutes between them)
That time is divided by 2
(4x minutes past 9:00 and x minutes left to reach 12:00)
132/3 = 44 minutes are left
OR
12:00- 44 minutes = 11:16
11:16-48 minutes =10:28
