1. [tex]x^{11}[/tex] 2. 10[tex]n^{9}[/tex] 3. 6[tex]x^{10}[/tex]
Step-by-step explanation:
1. [tex]x^{11}[/tex]
Imagine the expression is written like this:
(x)(x) * (x) * (x)(x)(x) * (x)(x)(x)(x)(x)
Simply add up the number of x's and have that number be the exponent.
There are 11 x's, so it will be [tex]x^{11}[/tex]
2. 10[tex]n^{9}[/tex]
Do the same as above, but this time remember that two negatives equal a positive.
10[tex]n^{9}[/tex]
3. 6[tex]x^{10}[/tex]
Again, two negatives equal a positive.
-3 x 2 x -1 = 6
Do the same as the above two.
6[tex]x^{10}[/tex]

There are 130 people in a sport centre. 73 people use the gym. 62 people use the swimming pool. 58 people use the track. 22 people use the gym and the pool. 29 people use the pool and the track. 25 people use the gym and the track. 11 people use all three facilities. A person is selected at random. What is the probability that this person doesn't use any facility
Answers
To find : Probability that person doesn't use any facility
Given : Total people = 130 ; People using gym (G), Swimming Pool (S), Track (T) = 73, 62, 58 respectively. People using G & P, P & T, G & T = 22, 29, 25. People using P & G & T = 11
So : Prob (G) = 73/ 130 , Prob (S) = 62/130 , Prob (T) = 58/130
P (G ∩ P) = 22 / 130 , P (P ∩ T) = 29 / 130 , P (G ∩ T) = 25 / 130 , P (P ∩ G ∩ T) = 11 / 130
Prob [ Person uses either P or G or T ] :
P (PUGUT) = P(G) + P (S) + P (T) - P (G ∩ P) - P (P ∩ T) - P (G ∩ T) - 2 P (P∩G∩T) = ( 73 + 62 + 58 - 22 - 29 - 25 - 22) / 130 = 95 / 130
Prob [Person uses neither P or G or T] : 1 - Pr [Person uses either P or G or T] = 1 - P (PUGUT) = 1 - (95 / 130) = 35 / 130
Hence, Probability that person doesn't use any facility = 35 / 130

SEBNI
Answers
Answer:
A. Amount(hours worked)
Step-by-step explanation:
Function notation is a way of converting a written description of a function to a concise form that is easy to read.
It is another way of representing the y-value in a function, y = ƒ(something)
Let's convert the word expression to function notation:
"The amount charged for labour depends on the time the repair technician works." "The amount depends on the hours worked." "The amount is a function of the hours worked." Amount = amount(hours worked) y = a(h)

A bicycle wheel turns at 80 rpm. If the rider travels 27.227 m in 10 seconds, what is the radius of the wheels of the bicycle?
Answers
Answer:
2.042 meters
Step-by-step explanation:
We have that the angular speed is 80 rpm and we can calculate the linear speed, we know that the linear speed is equal to the radius times the angular speed, like this:
v = w * r
w = 80 rpm, but we must pass it to seconds, that is:
80/60 = 1,333 rps, that is, revolutions per second, to have the same time unit as the linear speed.
v = distance / time = 27,227 / 10 = 2.7227
therefore, the radius would be:
r = v / w = 2.7227 / 1,333
r = 2.042
Which means that the radius is 2.042 meters.

En la tienda tienen estas ofertas : 1/4 kg de chorizo : 9,25 €. 1/2 kg de queso : 8,50€.¿Cuánto vale 1 kg de cada producto?¿Cuánto cuesta un queso de 2kg?
Answers
Answer: 1. €37 and €17
2. €34
Step-by-step explanation:
Given Data:
Cost of 1/4kg of chorizo = €9.25
Cost of 1/2kg of cheese = €8.50
Therefore:
1. Cost of 1kg of each product.
If 1/4 kg or chorizo cost €9.25,
1kg = 1/4 which is known as one fourth or one quarter. There are 4 one fourth in 1
1kg = 1/4 + 1/4 + 1/4 + 1/4
Or
1kg = 4 * €9.25
1kg = €37
Cost of 1kg of chorizo is €37
Cost of 1kg of cheese
If 1/2kg = €8.50
Then; 1kg = 1/2 + 1/2
1kg = €8.50 + €8.50
1kg = €17
Cost of 1kg of cheese = €17
2. Cost of 2kg of cheese.
If 1kg of cheese cost €17
2kg = 2 * €17
2kg = €34
Cost of 2kg of cheese is €34
