Paul wants to estimate the mean number of siblings for each student in his school. He records the number of siblings for each of 100 randomly selected students in the school. What is the parameter?
Answer:
A parameter is defined as a numerical or another measurable factor that conforms a set that defines a given system.
In this case, the only parameter that we have is the number of siblings that each one of the 100 students has.
For example, in a table:
#student #siblings.
1 3
2 1
3 4
... ...
In the left side, we have the "number of the student" that does not really matter, because the students are randomly selected, and at the right, we can see our only parameter in this study, that is the number of siblings that each student has.

Answer:
Value of [tex]x[/tex] :
[tex]x = -\frac{2}{5}[/tex]
Step-by-step explanation:
Solve for [tex]x[/tex] :
[tex]-25x = 10[/tex]
-Take [tex]25x[/tex] and divide it on both sides of the equation:
[tex]\frac{-25x}{-25} = \frac{10}{-25}[/tex]
[tex]x = -\frac{2}{5}[/tex]
So, the value of [tex]x[/tex] is [tex]-\frac{2}{5}[/tex].
If I want to buy a pair of sunglasses and the original price is $120, how much will I pay if they are 50% off? What if they were 25% off?
Answer:
$60, $90
Step-by-step explanation:
Amount paid when 50% off
=$ 120 - 50/100 * 120 = $ 120 - $60 = $60
Amount paid when 25% off
=$ 120 - 25/100 * 120 = $ 120 - $30 = $90

Suppose that J and K are points on the number line.
If JK = 10 and J lies at -17, where could K be located?
If there is more than one location, separate them with commas.
Answer:
-7, -27
Step-by-step explanation:
J is at -17. K is 10 units from J.
Start at point J, -17:
a) If you go 10 units to the right, you end up at -17 + 10 = -7
b) If you go 10 units to the left, you end up at -17 - 10 = -27
J can be at -7 or at -27
Answer: -7, -27

Let f(x) = 5x - 4 and g(x) = x^2- 1. Find (g•f)(0).
Answer:
[tex](g\cdot f)(0)=4[/tex]
Step-by-step explanation:
So we have the two functions:
[tex]f(x)=5x-4\text{ and } g(x)=x^2-1[/tex]
And we want to find:
[tex](g\cdot f)(0)[/tex]
This is the same as:
[tex]=g(0)\cdot f(0)[/tex]
So, find g(0) and f(0):
g(0):
Substitute 0 into g(x):
[tex]g(0)=(0)^2-1[/tex]
Square:
[tex]g(0)=0-1[/tex]
Subtract:
[tex]g(0)=-1[/tex]
And f(0):
Substitute 0 into f(x):
[tex]f(0)=5(0)-4[/tex]
Multiply:
[tex]f(0)=0-4[/tex]
Subtract:
[tex]f(0)=-4[/tex]
So, our equation is now:
[tex](g\cdot f)(0)=g(0)\cdot f(0)=(-1)\cdot(-4)[/tex]
Multiply:
[tex]=4[/tex]
So, our answer is 4.

Berks Lanes charges $4 per game of bowling and
$5 for the shoe rentals. If Roberto met his friends
to play and paid for 5 games and one shoe rental,
how much did he pay in all?
PLZ HELP THIS IS DUE IN 8 MINUTESSSSS
Answer:
25 $.
Step-by-step explanation:
4 (dollars per game) x 5 (how much games) = 20.
+ 5 $ for one shoe rental.
Robert will pay $25 for 5 games and one shoe rental.
Given that,
Berks Lanes charges $4 per game of bowling and $5 for the shoe rentals. Roberto paid for 5 games and one shoe rental, how much did he pay in all is to be determined.
In mathematics, it deals with numbers of operations according to the statements.
What is simplification?The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
Berks Lanes charges $4 per game of bowling and $5 for the shoe rentals
Let the number of games be x, and number of show use be y
Total cost for the games = 4x + 5y
Roberto paid for 5 games and one shoe rental implies
x = 5 and y = 1
Now,
Total money paid = 4 * 5 + 5 * 1
= 25
Thus, robert will pay $25 for 5 games and one shoe rental.

The ladder in a fire station is 29 feet (ft) tall. The ladder is anchored to the basement floor and the second floor ceiling. The basement floor is 12 feet below ground level. Identify the integers of the ends of the ladder below and above the basement floor
Answer:
top = 17ft
bottom = -12ft
Step-by-step explanation:
As seen in the badly drawn picture attached in this question we are trying to find the point at the top of the ladder and the point at the bottom of the ladder. As seen in the picture ground level has an altitude of 0 ft meaning that lower than this would be in the negatives. Since the basement floor is 12 feet below ground level then this point would be -12 ft. Now since we know that the ladder is 29ft tall we simply add this height to the basement floor value to get the value of the 2nd floor ceiling (top of the ladder).
29ft + ( -12ft) = 17ft
Therefore we can see that the point at the top of the ladder is 17ft.

Answer:
214°
Step-by-step explanation:
The arc subtending an angle at the centre are equal, that is
arc ED = 90° and
arc DF = 360° - (90 + 146)° = 360° - 236° = 124°
Thus
arc EDF = arc ED + arc DF = 90° + 124° = 214°
REASONING A high school band was selling ride tickets for the school fair. On the first day, 250 children’s tickets and 150 adult tickets were sold for a total of $550. On the second day, 180 children’s tickets and 120 adult tickets were sold for a total of $420. What is the price for each child ticket and each adult ticket?
a. Select a system of equations to represent this situation. Let x represent the cost of children’s tickets and y represent the cost of adult tickets.
A)
250x+120y=550 ; 180x+150y=420
B)
180x+150y=420 ; 180x+120y=420
C)
250x+150y=550 ; 180x+120y=420
D)
250x+150y=420 ; 180x+120y=550
The system of equation should be C) 250x+150y=550 ; 180x+120y=420
Important information:On the first day, 250 children’s tickets and 150 adult tickets were sold for a total of $550.

If g(x) =4x+2 and f(x) =3x-10
find g(f(3))
Answer:
[tex]g(f(3))=-2[/tex]
Step-by-step explanation:
So we have the two functions:
[tex]g(x)=4x+2\text{ and } f(x)=3x-10[/tex]
And we want to find g(f(3)).
So, let's find f(3) first:
[tex]f(3)=3(3)-10[/tex]
Multiply:
[tex]f(3)=9-10[/tex]
Subtract:
[tex]f(3)=-1[/tex]
Therefore, we can substitute -1 for f(3):
[tex]g(f(3))=g(-1)[/tex]
Now, find g(-1):
[tex]g(-1)=4(-1)+2[/tex]
Multiply:
[tex]g(-1)=-4+2[/tex]
Add:
[tex]g(-1)=-2[/tex]
And we're done!
So:
[tex]g(f(3))=-2[/tex]
1/3 (6y - 9) = -2y + 13
Answer: 3,75 ( 15/4)
Step-by-step explanation:
1/3 (6y - 9) = -2y + 13
6y/3 - 9/3 = - 2y + 13
2y - 2 = - 2y + 13
2y + 2y = 13 + 2
4y = 15
y = 15/4
y = 3,75
