Answer:
412 adults
Step-by-step explanation:
Let the number of adults be x
Let the number of children be y
If a total of 1,236 people attended the concert, then;
x + y = 1236 .....1
If there were twice as many adults as children who attended the concert, then;
y = 2x
Substitute y = 2x into 1
x + 2x = 1236
3x= 1236
x = 1236/3
x = 412
Hence 412 adults attended the concert.

A theater has group prices for tickets. The first ticket will cost $10 while each additional ticket costs $8. Which rule models the situation?
a. an= 10 + 8 (n - 1)
b. an-1= 10 + 8 (n - 1)
c. an= 18 (n - 1)
d. an-1= 18 (n - 1)
Answer: Choice A.
an = 10 + 8(n - 1)
=================================================
Explanation:
a1 = 10 is the first term
The common difference is d = 8 since we add 8 to each previous price to get the next price.
We have the arithmetic sequence with nth term of
an = a1 + d*(n-1)
an = 10 + 8(n - 1)
If you wanted, you could simplify that to get
an = 10 + 8n - 8
an = 8n + 2

Colin buys a tv for £530. It depreciates at a rate of 3% per year. How much will it be worth in 5 years? Give your answer to the nearest penny where appropriate.
Answer: In 5 years it will be worth £455
Step-by-step explanation:
Step 1
Given
The cost of the T.V. for Colin = £530.
The rate of depreciation per year = 3%
Time/ period = 5 years
Formulae to be used
F = P X (1 - r) ^ n
where
F = the future value after depreciation
P = the present value.
r =the interest rate per time period
n = the time/ periods
Step 2--- SOLVING
F = P X (1- r) ^ n
F= 530 x (1-0.03) ^ 5
=530 x 0.858734
=£455.129
Rounding up to the nearest penny where appropriate = £455

Order the functions from narrowest graph to widest graph.
11. h(x) = 3x2
12. g(x)= -
13. f(x)= x2
14. k(x) = -2x
guys please help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The order of functions from narrowest graph to widest graph is 3x², -x, x² and 2x. A graph is a structure that amounts to a set of items.
What is graph?A graph is a structure that amounts to a set of items in which some combinations of the objects are already in some manner "connected" in discrete mathematics, more specifically within graph theory.
The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge. A graph is typically shown diagrammatically as a collection of dots as well as circles representing the vertices and lines or curves representing the edges. The order of functions from narrowest graph to widest graph is 3x², -x, x² and 2x.
Therefore, the order of functions from narrowest graph to widest graph is 3x², -x, x² and 2x.

As the number of trials increase in experimental probability, the experimental probability will get farther away from the theoretical probability.
True
False
Explanation:
The more trials you do, the closer the experimental probability will get to the theoretical probability.
For example, if you flip a coin 1000 times, then you'll probably get around 500 heads or so. Maybe you could get 475 heads and 525 tails. This leads to an experimental probability of 475/100 = 0.475 of getting heads. If you flip a coin 10,000 times, then you are likely to have the experimental probability of getting heads move closer to 0.500

Using the equation ŷ = 5.4 + 1.7x, what is the predicted value if x is 1.2?
3.36
−3.36
7.44
−7.44
−2.47
Answer:
Using the equation ŷ = 5.4 + 1.7x, we can say that if x is 1.2, the predicted value will be 7.44.
Step-by-step explanation:
y=5.4+1.7(1.2)
Multiply 1.7 and 1.2 to get 2.04.
y=5.4+2.04
Add 5.4 and 2.04 to get 7.44.
y=7.44

Manuel wants to replace the wooden floor at his gym. The floor is in the shape of a rectangle. Its length is 40 feet and its width is 25 feet. Suppose wood flooring costs 11$ for each square foot. How much will the wood flooring cost for the floor?
Answer:
$11,000Step-by-step explanation:
Step one:
given data
the dimension of the gym is
length = 40ft
width= 25ft
Area= 40*25
Area= 1000ft^2
Step two:
if 1ft^2 will cost $11
then 1000ft^2 will cost x
cross multiply
x=1000*11
x=$11,000
The cost for the floor is $11,000
