The statistic which is most appropriate in the given situation is Mode.
Mode is defined as the statistical method which gives the value of an entity that occurs the greatest number of times in a set of values of data. For example, if the marks of 5 students scored in a test are given as 35, 45, 35, 35, 50 then the mode of the given set of data is 35 as it occurs the maximum number of times. Here, the student is sure that the principal will call out the name of a certain number of tables very often. She keeps track of the tables over 21 days and as the table number was called out for the maximum number of times within 21 days the value of the table number will be given by the Mode of the data.
Thus, the most suitable method is Mode.

Answer:
Step-by-step explanation:
Equation of line k is y = (-4/7)x + 1
point (-5,-10); m = -4/7
Line L is perpendicular to k so the perpendicular slope will be 7/4
Equation of line L is (y - y1) = m(x-x1)
y+10 = (7/4) (x +5)
4y + 40 = 7x + 35
4y = 7x - 5
y = (7/4)x - (5/4)

A hotel rewards club wants to randomly select 100 of its 5,000 members to participate in a survey. The club wants to determine if people’s opinions differ based on age. There are 2,200 members between the ages of 25 and 50, and there are 2,800 who are age 51 or older. The club decides to randomly select 44 members between the ages of 25 and 50, and 56 members ages 51 and older. Is the sample of 100 members a simple random sample? Yes, because the hotel rewards members were randomly selected for the sample. Yes, because each hotel rewards member has the same chance of being selected. No, because the sample of 100 is too small a sample to represent the population. No, because each sample of 100 does not have the same chance of being selected.
Answer:
No, because each sample of 100 does not have the same chance of being selected.
Step-by-step explanation:
Simple random samples require that every possible sample of the population has an equal chance of being selected. Because of the fact that certain ages are being picked at certain amounts, not every possible sample has the same chance of being selected, so this is not an SRS.
Answer:
D.
Step-by-step explanation:
No, because each sample of 100 does not have the same chance of being selected.

Based on the given information, what will be the retained earnings for a given accounting period?
Items Amount ($)
total expenses 50,000
total income 75,000
dividend paid 5,000
A.
30,000
B.
15,000
C.
25,000
D.
20,000
Answer:
20,000
Step-by-step explanation:
It is right on plato/edmentum
You just take 75,000-50,000=25,000 and then since it is dividend paid you will subtract the 5,000 from 25,000 and then you will get 20,000.
So 20,000 is your answer. :)

can someone solve -192= -6 (6x - 4) step by step?
Answer:
x= 4 2/3 OR 14/3 OR 4.6... –– 4 2/3 and 4.6... are the simplest form.
Step-by-step explanation:
Your original equation is -192 = -6 (6x - 4):
1. -192 = -6 (6x - 4)
Use distributive property and multiply: -6 x 6x = -36x and -6 x -4 = 24:
2. -192 = -36x + 24
We now move the +24 onto the other side of the equation, -192. Add 24 onto -192 and since we're moving the 24 on the left side of the equation, 24 will removed, so -24 on the right side of the equation:
3. -192 + 24 = -36x + 24 - 24
Divide both sides of the equations by -36 to get "x" by itself:
4. -168 / -36 = -36x / -36
Simplify the fraction of 24/36 by 12:
5. 4 24/36 = 4 2/3 or 14/3 or 4.6... = x
4 2/3, 14/3, 4.6... = x

At a school assembly four out of the first 10
students were wearing spirit wear. Based on
this information, if 500 students were at the
assembly, then how many students could be
expected to be wearing spirit wear?
if 500 students were at the assembly, then the number of students who were wearing spirit wear is 200 students.
Calculations and Parameters:Since we know that:
4/10 of every student is wearing spirit wear.
The total number of students was 500
Hence,
We can express this as:
4/10 x 500
=4 x 50
= 200

Equations are steeper when their slope's positive value is higher (ignore negatives when determining how steep a slope is). The slope is the value in front of x. If there isn't a value in front of x, then it is assumed to be 1.
this is a geometry question I know the answers are 81 and 9 because of the back of the book but I don't understand how it got to that point
Answer:
18°
Step-by-step explanation:
let the angle be x , then its complement is 90 - x
we are told the angle is [tex]\frac{1}{4}[/tex] of its complement , then
x = [tex]\frac{1}{4}[/tex] (90 - x) ← multiply both sides by 4 to clear the fraction
4x = 90 - x ( add x to both sides )
5x = 90 ( divide both sides by 5 )
x = 18
then the angle is 18° and its complement is 90° - 18° = 72°
Answer:
The angles measure 18° and 72°.
Step-by-step explanation:
81 and 9 is not correct for this problem.
9 is not 1/4 of 81, so 9 and 81 cannot be the answer, although it is true that angles measuring 9° and 81° are complementary since 9 + 81 = 90.
You need to know what complementary angles are.
Definition:
Two angles are complementary if the sum of their measures is 90°.
Each angle is said to be the complement of the other angle.
You have two complementary angles, both of whose measures are unknown.
Call the smaller measure x and the larger measure y.
Since the angles are complementary, the sum of their measures is 90°.
x + y = 90
The measure of one angle is 1/4 the measure of the other angle.
If the smaller angle's measure is 1/4 of the larger angle's measure, then the larger angle's measure is 4 times the smaller angle's measure.
That means that y = 4x.
You have two equations and two unknowns:
x + y = 90
y = 4x
This is a system of equations. We will solve it using the substitution method.
Since y = 4x, where you see y in the first equation, substitute it with 4x
x + y = 90
x + 4x = 90
5x = 90
Divide both sides by 5.
x = 18 <---- smaller angle
y = 4x = 4(18) = 72 <----- larger angle
Answer: The angles measure 18° and 72°.
Check: Do the measures 18 and 72 add to 90?
18 + 72 = 90 Yes.
Is the measure of the smaller angle 1/4 the measure of the larger angle?
18/72 = 9/36 = 1/4 Yes.
18 and 72 is the correct answer.
Dennis is joining an online video game service. He will pay $25.50 to purchase each game plus a one-time foe of $4500 to join
Which equation can be used to find y, the total cost to buy x games?
(A) y = 25 5x + 45
(B) y - 25.5 45
(C) y 45x + 255
(D) y=452 25.5
Answer:
I am pretty certian it is A
Step-by-step explanation:
You add the x to 25.50 because it is unknown how many games he will buy and add the one time pay of 4,500 to enter the service/company
So it is y= 25.50x + 45

15. Find the 50th term if d = 5 and a = 10
Step-by-step explanation:
⇒12)It is an arithmetic sequence.
d=2-1=3-2=4-3=1
a(n) = a +(n-1)d
a(n) = 1+(n-1)1
The next three terms:
a(6) = 1+(6-1)1=6
a(7) = 1+(7-1)1=7
a(8) = 1+(8-1)1=8
⇒13)It is an arithmetic sequence.
d=0-3=-3-0=-6+3=-3
a(n) = a +(n-1)d
a(n) = 3+(n-1)-3
The next three terms:
a(5) = 3+(5-1)-3=-9
a(6) = 3+(6-1)-3=-12
a(7) = 3+(7-1)-3=-15
⇒14)It is not an arithmetic sequence.

If there is a base of 9 and a area of 12 how do you explain how to find the height.
Answer:
height = 8/3
Step-by-step explanation
I'm assuming that this is a question to a triangle. So since an area of a triangle is 12 you solve by the formula 1/2(base)(height). You would solve for height so your equation would look smth like this: 12 = 1/2(base)(height). So you would end up with 24/8 which would simplify to 8/3.
