Step-by-step explanation:
x - is the amount of DVDs
so 2x + 5x + 7x = 56
14x = 56
x = 4
so comedy is 2x4 = 8; action 7x4 = 28 and horror is 5x4 = 20 DVDs

Answer:
B. 4/3
Step-by-step explanation:
[tex] \frac{ {4}^{ - 3} . {3}^{4} . {4}^{2} }{ {3}^{5} . {4}^{ - 2} } \\ \\ = \frac{ {4}^{ - 3} . {4}^{2 + 2} }{ {3}^{5 - 4}} \\ \\ = \frac{ {4}^{ - 3} . {4}^{4} }{ {3}^{1}} \\ \\ = \frac{ {4}^{4 - 3} }{ {3}^{1}} \\ \\ = \frac{ {4}^{1} }{ {3}^{1}} \\ \\ = \frac{4}{3} [/tex]
Answer:
B. 4/3
Step-by-step explanation:
(4^-3 . 3^4 . 4^2)/(3^5 . 4^-2)
4^-3 . 4^2/ 4^-2 . 3^4/ 3^5
4^(-3+2-(-2)) . 3^(4-5)

What are the coordinates of D’ when the quadrilateral is reflected across the line y = x?
On a coordinate plane, quadrilateral A B C D has points (1, 2), (2, 4), (4, 3), (3, 1).
(1, 3)
(2, 4)
(3, 4)
(1, 1)
Answer:
(1, 3)
Step-by-step explanation:
If quadrilateral ABCD is reflected across the line y = x, then the x- and y-coordinates get reversed. Since the coordinates of point D are (3, 1), then the coordinates of point D' are (1, 3).

one number is three times another, and four times the smaller added to five times the greater amounts to 133; find them
Step-by-step explanation:
S=smaller number; L=larger number=3S
.
4S+5L=133
4S+5(3S)=133
4S+15S=133
19S=133
S=7 ANSWER 1: The smaller number is 7.
.
L=3S=3(7)=21 ANSWER 2: The larger number is 21.
.
CHECK:
4S+5L=133
4(7)+5(21)=133
28+105=133
133=133

If p(x)= x^2 - 2root2x + 1, then p(3root2)= ?
Answer:
19 - 2^(7/4)√3 or
13.174 to nearest thousandth.
Step-by-step explanation:
I am interpreting this as x^2 - 2√(2x) + 1
p(3√2) = (3√2)^2 - 2√(2*3√2) + 1
= 18 - 2√(6√2) + 1
= 19 - 2* √6 * 2^1/4
= 19 - 2*√2*√3*2^1/4
= 19 - 2^(7/4)√3.
= 13.174 to the nearest thousandth.

A statistical procedure that estimated regression equation coefficients that produce the lowest sum of squared differences between the actual and predicted values of the dependent variable is called .
Answer:
Ordinary least squares
Step-by-step explanation:
The ordinary least squares means the estimations that done for parameters in a regression model by lowering the sum of the square residuals. It also predicted the coefficient of the regression equation that generate the actual and the expected values of the dependent variable is known as ordinary least squares

What is the solution set of {x | x 5}?
1. the empty set
2. all real numbers
3. the numbers between -5 and 5
4. all numbers less than -5 and greater than 5
Answer:
3. the numbers between -5 and 5
Step-by-step explanation:
Let set A= [tex]\{x| x>-5\}[/tex] and set [tex]B=\{x | x<5\}[/tex].
The solution set of A and B is the solution set of A∩B
The solution set of A is all the real number x which is greater than -5.
The solution set of B is all the real number x which is less than 5.
Therefore, the solution set of A∩B is all the real numbers between -5 and 5.
Hence, option (3) is correct.

There are 874 pieces of candy in the piñata. There are 23 children at the party, and they all agreed to split the candy equally. How many pieces of candy will each child receive?
Answer:
38 candies.
Step-by-step explanation:
Given the following data;
Total number of candy = 874
Total number of children = 23
Since we know that they are all sharing it equally, each child would get;
Each child = 874/23
Each child = 38 candies.
Simplify: x^2y-5 * x^y+8

How long is the light beam from the top of the lighthouse to the ground? Round to the nearest tenth. The light house is 25m tall and a boat is 180m from the base
Answer:
181.7m
Step-by-step explanation:
The set up is a right angled triangle with;
Height of the light house = 25m = opposite side
The distance of the boat from the base = 180m = Adjacent
The distance of the light beam from the house = Hypotenuse = x
Using pythagoras theorem;
x² = 25²+180²
x² = 625+32400
x² = 33025
x = √33,025
x = 181.7m
Hence distance of the light beam from the top of the lighthouse to the ground is 181.7m to the nearest tenth

All you have to do in this question is to substitute what they are telling you.
First blank:
They told us that m is 0 so if we plug that into the equation we can get s.
[tex]2m+4s=16\\2(0)+4s=16\\4s=16\\s=4[/tex]
In this one if m is 0, s will have to be 4.
Second blank:
They told us that s is 3 so if we plug in that into the equation we can get m.
[tex]2m+4s=16\\2m+4(3)=16\\2m+12=16\\2m=4\\m=2[/tex]
In this one if s is 3, m will have to be 2.
Third blank:
They told us that m is -2 so if we plug that into the equation we can get s.
[tex]2m+4s=16\\2(-2)+4s=16\\-4+4s=16\\4s=20\\s=5[/tex]
In this one if m is -2, s will be 5.
Fourth blank:
They told us that s is 0 so if we plug into the equation we can get m.
[tex]2m+4s=16\\2m+4(0)=16\\2m=16\\m=8[/tex]
In this one if s is 0, then m will be 8.

Melanie has a ribbon that is 18 inches long. She cut the ribbon into 3 equal pieces. Then she cut each of those pieces in half. How many small pieces of ribbon are there? how long is each pieces
Answer:
I guess there are 6 small pieces but dont know how long they are sry
Answer:
12 small piece of ribbon, each 3/2 inches long
Step-by-step explanation:
one 18" long ribbon divided into 3 equal pieces will produce three 6 inch ribbons
three 6" ribbons, each one cut in half (or divided by 2), equals 12 pieces
each one being 18/12 inches long; which reduces to 3/2
the graph shows the cost of some taxi journeys. work out a formula for C in terms of n.
Given:
The graph of cost of taxi with respect to number of miles.
To find:
The formula for C in terms of n.
Solution:
In the given graph x axis represents the number of miles (n) and y-axis represents the cost of taxi (C).
From the given graph it is clear that, the line passes through the points (0,3) and (5,6). So, the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-3=\dfrac{6-3}{5-0}(x-0)[/tex]
[tex]y-3=\dfrac{3}{5}(x)[/tex]
Adding 3 on both sides, we get
[tex]y=\dfrac{3}{5}x+3[/tex]
Putting y=C and x=n, we get
[tex]C=\dfrac{3}{5}n+3[/tex]
Therefore, the required formula is [tex]C=\dfrac{3}{5}n+3[/tex].
