An experiment's or random trial's sample space is the set of all conceivable outcomes or results. The correct option is C.
What is a sample?A sample is a statistically significant subset of a larger population. The utilisation of samples enables researchers to conduct investigations with more manageable data and more quickly. Randomly chosen samples exhibit little bias if they are large enough, but obtaining such a sample can be costly and time-consuming.
Given that a population consist of 85,000 people. Now, the number of members of the population that being surveyed could result in a parameter but not a sample static is 8500. This is because a parameter is a value that describes a specific attribute of the population as a whole. A sample survey cannot provide this information. To determine the real value of a parameter, the entire population must be examined.
Hence, the correct option is 85,000.

Four penguins would satisfy a polar bear's appetite for 12 hours. A polar bear has a
territory of 10 square miles. There are 1000 penguins per square mile. What percent
of penguins (number eaten divided 1000 times 100) in the 10 square miles will a wild
polar bear eat?
Answer:
0.04%
Step-by-step explanation:
If there are 1000 penguins per square miles, the total number of penguins in a 10 square miles will be 1000*10 = 10,000 penguins/10square miles
Since a polar bear has a territory of 10 square miles, and can only eat four penguins within the 10square miles;
Percentage of penguins that the polar bear can eat will be expressed as;
number of penguin eaten per 10square miles/total number of penguin per 10square miles * 100
Percentage of penguins that the polar bear can eat = 4/10,000 * 100%
Percentage of penguins that the polar bear can eat = 4/100%
Hence, the percentage of penguins that the polar bear can eat in the 10 square miles is 0.04%

Choices 1 and 5
Step-by-step explanation:

Correct choices:
155 - 296 = 25 - 166
This is obtained by subtracting 296 and 166 from both sides of initial equation166 - 25 = 296 - 155

unit price per month? Show your work.
Answer:
The correct answer is $4.75/month.
Step-by-step explanation:
To find the unit price per month, or the amount that of the subscription that will be paid each month, we must divide the total price ($28.50) by the number of months covered (6 months).
$28.50/6 = $4.75
Therefore, the unit price per month is $4.75/month.

The vertices of ∆ABC are A(7,3),B(−8,6),C(0,−5). If ∆ABC is translated along the vector <−9,5>, what are the coordinates of the vertices of ∆A'B'C' ?
Answer:
The coordinates of the vertices of [tex]\bigtriangleup A'B'C'[/tex] are [tex]A'=(-2,8)[/tex], [tex]B'=(-17,-4)[/tex] and [tex]C'=(-9,0)[/tex].
Step-by-step explanation:
Let be [tex]A =(7,3)[/tex], [tex]B = (-8,6)[/tex] and [tex]C = (0,-5)[/tex] the vertices of the original triangle, as well as [tex]\vec t = \left<-9, 5\right>[/tex], the coordinates of the vertices of the new triangle are, respectively:
[tex]A' = A + \vec t[/tex]
[tex]A' = (7,3)+(-9,5)[/tex]
[tex]A' = (7-9,3+5)[/tex]
[tex]A'=(-2,8)[/tex]
[tex]B' = B + \vec t[/tex]
[tex]B' = (-8,6)+(-9,5)[/tex]
[tex]B' = (-8-9,-9+5)[/tex]
[tex]B'=(-17,-4)[/tex]
[tex]C' = C + \vec t[/tex]
[tex]C' = (0,-5)+(-9,5)[/tex]
[tex]C' = (0-9,-5+5)[/tex]
[tex]C'=(-9,0)[/tex]
The coordinates of the vertices of [tex]\bigtriangleup A'B'C'[/tex] are [tex]A'=(-2,8)[/tex], [tex]B'=(-17,-4)[/tex] and [tex]C'=(-9,0)[/tex].
You and your family attend a Broadway show in New York City. The show begins at
6:58pm and ends at 9:46pm. How many seconds long is the show?
From 7:00 to 9:46 we see it passes 2 hours and 46 minutes.
But it started 6:58 . So we add +2 minutes. 46+2 = 48
2 hours and 48 minutes.
But we must find the second form.
1 hours = 60 minutes = 3600 seconds
So, 2 hours = 120 minutes = 7200 seconds.
and 1 minutes = 60 seconds
48 minutes = 60 x 48 = 2880 seconds.
7200 + 2880 = 10080 seconds.
1. Write the interval shown on the number line
below
3 4 5 6 7 8
as an inequality
using set notation
Answer:
[tex]x\geq 5[/tex]
[tex]\{x\ |\ x \geq 5\}[/tex] OR {5, 6, 7, 8, .....}
Step-by-step explanation:
First of all, let us have a look at the interval shown on the number line and try to understand it properly.
The number line shows positive numbers starting from 3 that means numbers indicated will be positive numbers.
The number highlighted starts from 5 and there is filled circle at 5.
So, 5 is included in the interval.
The arrow is from 5 towards 8 and so on..
That means Numbers greater than or equal to 5 are represented by the interval.
So, writing as an inequality
Let [tex]x[/tex] represents one of the numbers.
Hence, inequality can be written as:
[tex]x\geq 5[/tex]
Using the set notation:
[tex]\{x\ |\ x \geq 5\}[/tex]
OR
{5, 6, 7, 8, .....}

Thank you.
Answer:
[tex] \boxed{ \boxed{ \bold{ \sf{(x + 7) \: and \: (x - 6)}}}}[/tex]Step-by-step explanation:
[tex] \sf{ {x}^{2} + x - 42}[/tex]
Here, we have to find two numbers which subtracts to 1 and multiplies to 42
⇒[tex] \sf{ {x}^{2} + (7 - 6)x - 42}[/tex]
⇒[tex] \sf{ {x}^{2} + 7x - 6x - 42}[/tex]
Factor out x from the expression
⇒[tex] \sf{x(x + 7) - 6x - 42}[/tex]
Factor out 6 from the expression
⇒[tex] \sf{x(x + 7) - 6(x + 7)}[/tex]
Factor out x + 7 from the expression
⇒[tex] \sf{(x + 7)(x - 6)}[/tex]
So, the possible dimensions of the rectangle are x + 7 and x - 6 .

Given T(x, y)=(x+2, y+5), state the translation S(x, y) that would yield the identity transformation, I=S(T(x,y)).
Answer:
The translation S(x, y) for the identity transformation, I = ST(x, y) is S(x, y) = ( x - 2, y + 5)
Step-by-step explanation:
Identity transformation is the transformation that results in the copying of the source data to the destination data without change.
Given that T(x, y) = (x + 2, y + 5)
The identity transformation I = S(T(x, y)) that would allow a data (x, y) to remain the same at the destination after the transformation T(x, y) is given as follows;
Where S(x, y) = ( x - 2, y + 5), we have;
S(T(x, y)) = S(x + 2, y + 5) = (x + 2 - 2, y + 5 - 5) = (x, y)
Therefore the translation S(x, y) that would yield the identity transformation, I = ST(x, y) is S(x, y) = ( x - 2, y + 5).

There is a triangle called XYZ the measurements are 12m 15m and 9m. What 2 kinds of a triangle is that? This would be helpful if someone answered this! UwU Tanks
Answer:
Right angle triangle
Step-by-step explanation:
12m
15m
9m
Assume the Longest side=15m
Using Pythagoras theorem
c^2=a^2 + b^2
Where,
c=hypotenuse
a=adjacent
b=opposite
Let a=9m
b=12m
c^2=a^2 + b^2
=9^2 + 12^2
=81 + 144
c^2=225
c=√225
=15m
Therefore, the triangle XYZ is a right angle triangle

3) Taylor's soccer team purchased uniforms and equipment for a total of $912. The equipment costs $612 and the uniforms cost $25 each. How many uniforms did the school purchase?
Answer: They purchased 12 uniforms
Step-by-step explanation:
If the equipment cost $612 in total and the uniforms cost $25 each and they spent a total for $912 then we could represent it by the equation 25x + 612 = 912 where x is the number of uniforms that the school purchase.
25x + 612 = 912 solve for x by subtracting 612 from both sides
612 612
25x = 300 divide both sides by 25
x = 12
6. Audrey's monthly car payment is $350 and
she needs to save at least $35 each month for
gas. If Audrey is paid $17.50 an hour, write
and solve an inequality to represent the
number of hours she must work in a month to
pay for her car payment and gas.
Answer:
22 hours
Step-by-step explanation:
For one month, Audrey has to pay $350 for her payment and $35 for gas, meaning that she will need to pay $385 per month.
$350 + $35 = $385
Audrey makes $17.50 an hour. Set up an equality to find the amount of hours she must work to pay for her car payment and gas.
17.50x > 385
(17.50x)/17.50 > 385/17.50
x > 22
Audrey must work at least 22 hours to pay for her car payment and gas.

Answer: D. Set B has a higher mean and a Higher standard deviation than Set A
Step-by-step explanation:
Set A and Set B has the same amount of data and all are identical except the maximum. In this scenario, the larger the numbers, the higher the mean. Since the maximum of Set B is greater that Set A, Set B has a higher, mean.
--------------------------------------------
The higher the standard deviation, the larger the gap between data sets. Since Set B has a larger maximum, this means it is further away from other data comparing to Set A, thus, Set B has a higher standard deviation
