If there are 8 pieces to choose from, there are 1,680 different ways distinct displays are possible.
How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]
This is called permutation of k items chosen out of m items (all distinct).
To find the Ways can 8 pieces of art in the front window be arranged in the display window.
Let us use permutation to find the number of ways can 8 pieces of art in the front window be arranged in the display window.
here we have
n= 8
r= 4
substituting the values,
[tex]^nC_r = \dfrac{n!}{ (n-r)!}\\\\^8C_4 = \dfrac{8!}{ (8-4)!}\\\\^8C_4 = \dfrac{8!}{ (4)!}\\\\^8C_4 = 8 \times 7 \times 6\times 5\\\\^8C_4 =1680[/tex]

Suppose a jar contains 11 dimes, 21 nickels, and 12 pennies. Barbie selects a coin and puts it back in the jar and then Darren selects a coin from the jar. Is this a set of independent or dependent events?
Answer:
Independent
Step-by-step explanation:
Barbie selecting a coin and putting it back in has no effect on Darren selecting a coin from the jar, as the numbers of each coin never changed. So, both events are independent with neither relying on the other.

Hannah and Anthony are siblings who have ages that are consecutive odd integers. The sum of their
ages is 92. Which equations could be used to find Hannah's age, h, if she is the older sibling?
Answer:
2h+92
Step-by-step explanation:
The equation that will represent the sum of the age of Hannah and Anthony will be 2h+2=92.
Let the age of Hannah be x. and Since the age of Hannah and Anthony are two consecutive odd integers, therefore, the age of Anthony will be (h+2).
As it is given that the sum of the ages of the two other person is 92, therefore, the equation that will represent the sum of the age of the two persons can be written as, 2h+2=92
Thus, the equation that will represent the sum of the age of Hannah and Anthony will be 2h+2=92.

Find the unknown length of the side labeled x.
When we are given sides and an angle, and a right triangle (seemingly), the easiest method of solving is using trigonometry.
Remember: SOH-CAH-TOA
Looking from the given angle, we are given the opposite side and want to know the hypotenuse. Therefore, we should use the sin function.
sin(34) = 2 / x
(x)(sin(34)) = 2
x = 2 / sin(34)
x = 3.7801
x = 3.7801

Remember that complementary angles add up to 90°. The angle that i s complementary to 63° is 27°.
Also recall the co-function identities:
sin (90° – x) = cos xcos (90° – x) = sin xThis means that [tex]\cos(90^\circ-27^\circ)=\sin(27^\circ)\approx0.454[/tex].

Step-by-step explanation:
Given: [{36√(6) + 6^(5/2)} / (108×12)]² = 6ⁿ
Asked: Find the value of n = ?
EXPLANATION:
Given that:
[{36√(6) + 6^(5/2)} / (108×12)]² = 6ⁿ
⇛[{(6)² * (6)^(1/2) * (6)^(5/2}/(36 * 3 * 12)]² = 6ⁿ
⇛[{6² * 6^(1/2) * 6^(5/2)}/(36 * 36)]² = 6ⁿ
⇛[{6² * 6^(1/2) * 6^(5/2)}/(6*6 * 6*6)]² = 6ⁿ
⇛[{6² * 6^(1/2) * 6^(5/2)}/(6² * 6²)]² = 6ⁿ
⇛(6³⁻²)² = 6ⁿ
⇛(6¹)² = 6ⁿ
⇛6² = 6ⁿ

PLEASE ANSWER BOTH QUESTIONS DUE TODAY!!!! (19 POINTS)
Answer:
A) 8,500
B) B, C
Step-by-step explanation:
A) This seems to be a conversion problem. Since she runs 3 km every Monday Wednesday, and Friday, she would be running 6 km in total every week EXCLUDING the 2,500 meters. Since the question asks how many meters Kailee runs, you would need to convert 6 km to m and add the result to 2,500 meters. To convert km to m you just need to divide the value by 1000 (if your teacher asks for the full conversion method its 6 km * 1 m/1000 km or [tex]6 km * \frac{1m}{1000 km}[/tex]), so 6 km is 6,000 meters. Adding 6,000 to the left over 2,500 from Saturday, the final answer will be 8,500.
B) For the second question, the answer are the two angles BELOW angle A (I'm guessing it is choice B and C). A right angle can be envisioned as a corner of a square or rectangle. The only angle which are larger (wider) are the angles below A (with the long hand pointing at 1 and the long hand pointing at 2).
Simplify the following:
a. a+a+a+a+a+a
b. 5x-4x+10x
c. 9t+3t-6t
d. -5j+11j+j
=(a+a+a+a+a+a)
= 6a
b. 5x-4x+10x=(5x+−4x+10x)
= 11x
c. 9t+3t-6t=(9t+3t+−6t)
= 6t
d. -5j+11j+j=(−5j+11j+j)
= 7j
a)= 6a
b)= 11x
c)=6t
d)= 7j
have a great day!On the same coordinate plane mark all points (x,y) such that
(A) y=x+3
(B) y=-x+3
(C) y=|x|+3
The graphs of the 3 given functions can be seen in the image attached at the end.
How to mark all the wanted points?
Here we basically want to graph the next 3 functions:
y = x + 3
y = -x + 3
y = |x| + 3
So, the first two are linear equations. To graph these we just need to find two points on the line and connect them with a line.
The last one is the absolute value function translated up by 3 units.
So, to give an example of how to graph the first equation, first we evalaute in x = 0, then we get:
y = 0 + 3 = 3
So we have the point (0, 3)
For that same line we can evaluate in x = 1
y = 1 + 3 = 4
Then we also have the point (1, 4).
Now we have 2 points, we can just connect them with a line.
The graph of the 3 equations can be seen below.
A is the blue line, B is the red line, C is the orange graph.
