Which data set has a median of 15?
18, 9, 19, 16, 6, 20.13
09, 17, 13, 15, 16, 8, 12
18, 15, 11, 14, 19, 15, 6
O 7, 16, 14, 16, 11, 7, 17
Help please.
Median is the middle value.
Each set has 7 numbers so put the numbers in order from smallest to largest. The median would be the 4th number in the sets.
Only 2 sets have the number 15 in them so those are the only two you need to look at.
The 3rd choice is the correct answer.
Fred helped his mom make 40 dozen cupcakes for the last bake sale. For this sale, he is going to help make 20% more cupcakes. How many dozen cupcakes will Fred and his mom make?
Answer:
48 dozen cupcakes
Step-by-step explanation:
20 percent more is 120 percent overall, which as a decimal is 1.2. Multiply 40 by 1.2 and you have your answer.
1.2 * 40 = 48

4x - 2y = 6
Which statement is true about the solution to the system?
O A. There are infinitely many solutions because these lines are parallel to each other,
OB. There are infinitely many solutions because these lines are the same line.
O C. There are no solutions because these lines are parallel to each other.
D. There are no solutions because these lines are the same line.
Answer:
option c

Carter is solving for x by the process of completing the square for the following
problem:
3x^2+ 12x-24 = 0
He got to this point below:
Type the number that goes in the "?" spot:
(x+?)2 = 12
Answer:
The number that goes in place of the question mark is 2.
Step-by-step explanation:
Let's solve it!
3x² + 12x - 24 = 0
First we can factor 3 out of each term:
x² + 4x - 8 = 0
Now we'll add 12 to both sides to complete the square:
x² + 4x + 4 = 12
And finish it off:
(x + 2)² = 12
So the answer to the question is 2
Bonus:
We can also now solve this for x:
(x + 2)² = 12
x = √12 - 2
x = 2√3 - 2
x ≈ 2 × ±1.732 - 2
x ≈ 1.464, -5.464

Solve the equation. (Find all solutions of the equation in the interval [0, 2pi). Enter your answers as a comma-separated list.)
(3 sin(2x) + 3 cos(2x))^2=9
I got
[tex]0.75 + 2\pi \times n[/tex]
[tex]5.28 + 2\pi \times n[/tex]
[tex]1 + 2\pi \times n[/tex]
5.53+2pi times n
WORK:
[tex](3 \sin(2x) + 3 \cos(2x) )) {}^{2} = 9[/tex]
[tex] \sin(2x) + \cos(2x) {}^{2} = 3[/tex]
[tex] \sin(x) + \cos(4 {x}^{2} ) = 3[/tex]
[tex]4 {x}^{2} + x = 3[/tex]
[tex]4 {x}^{2} + x - 3 = 0[/tex]
[tex](4x {}^{2} + 4x - 3x - 3 = 0[/tex]
[tex]4x(x + 1) - 3(x + 1) = 0[/tex]
[tex](4x - 3)(x + 1)[/tex]
Solve for x
[tex]4x - 3 = 0[/tex]
[tex]4x = 3[/tex]
[tex]x = \frac{3}{4} [/tex]
[tex]x + 1 = 0[/tex]
[tex]x = - 1[/tex]
While -1 is a solution, it isn't within the interval of 0,2pi.
However, we can use the reference angle identity
[tex] \cos(x) = \cos(x + 2\pi) [/tex]
So some more possible points are
[tex] - 1 + 2\pi[/tex]
Since it on a interval, it must be less than 2 pi or 6.28.
Let find some more points
[tex] - 1 + 2\pi = 5.28[/tex]
So 5.28 is a point,
[tex] \frac{3}{4} + 2\pi = 7.03[/tex]
That is too big since -6.28 is smaller than 7.03
We can use the identity
[tex] \cos(x) = \cos( - x) [/tex]
[tex] \cos( - 1) = \cos( 1 ) [/tex]
1 is smaller than 2pi so it is true.
[tex] \cos( \frac{3}{4} ) = \cos( - \frac{3}{4} ) [/tex]
Negative 3/4 is smaller than zero so it not a solution.
[tex]0.75[/tex]
[tex]5.28[/tex]
[tex] 1[/tex]
Make sure to include
[tex]2\pi \times n[/tex]
so
[tex]0.75 + 2\pi \times n[/tex]
[tex]5.28 + 2\pi \times n[/tex]
[tex]1 + 2\pi \times n[/tex]
We can also -3/4 plus 2 pi.

An item has a listed price of $65. If the sales tax rate is 5%, how much is the sales tax (in dollars)?
Answer:
3.25$
Step-by-step explanation:
What is the value of 6(2b-4) when b=5?
Replace b with 5:
6(2(5)-4)
Simplify:
6(10-4)
Subtract:
6(6)
Multiply to get the answer: 36
The answer is 36
Hey there!
6(2b - 4)
= 6(2(5) - 4)
= 6(10) - 4)
= 6(10) + 6(4)
= 60 - 24
= 36
Therefore, your answer should be: 36

Mariko and her friend spent $24.50 on
lunch. Their lunches cost the same amount,
and they used a $4 off coupon. Determine
the cost of each lunch.
The cost: $14.25
Equation: 24.5=2c-4
The cost of each lunch is $10.25.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given;
Mariko and her friend spent $24.50 on lunch.
Their lunches cost the same amount,
and they used a $4 off coupon.
That means,
they spent = 24.5 - 4
= 20.50
And 20.50 divided by 2,
we get,
20.50/2
= 10.25
Therefore, $10.25 is the cost of each lunch.

The number of square tiles of side 25cm which can be paved on a rectangular floor of 3m
× 2m is:
Answer:
96 square tiles can be paved on a rectangular floor.
Step-by-step explanation:
First, we need to find the area of the square tiles:
[tex]A_{t} = (25 cm)^{2} = 625 cm^{2}[/tex]
Now, the area of the rectangular floor is:
[tex] A_{f} = 3m*2m = 6 m^{2}*\frac{(100 cm)^{2}}{1 m^{2}} = 60000 cm^{2} [/tex]
Finally, the number of square tiles which can be paved on a rectangular floor is:
[tex] N = \frac{A_{f}}{A_{t}} = \frac{60000 cm^{2}}{625 cm^{2}} = 96 [/tex]
Therefore, 96 square tiles can be paved on a rectangular floor.
I hope it helps you!
