Answer:
A. 14
Step-by-step explanation:
The smallest number of socks to pull out to be assured that we get a blue pair of socks is 14. (Option A)
What is pigeonhole principle?If there are n objects to be putted into m containers such that n > m, then at least one container will have two objects.
Suppose the worst is happening when you're pulling the socks out.
The total number of colors is 2.
Now the worst case is when the pair is not completed until we draw all the yellow color.
That will happen at 12 + 1 = 13 draws (pair needs 2 blue, and the worst will happen that in initial trials, the yellow socks are not letting the pair get completed, which means at max 1 blue sock and rest 12 socks are drawn, which will get at max 13 draws).
But now any more sock pulled will have to be falling into the blue color category we already have. (this is exactly the pigeonhole principle's use).
After 13 times, you will start getting blue socks.
Since you need a pair of blue socks, you need to pull out socks 1 more time.
So total 14 pulls were required if the conditions were like resisting us at maximum.
In most of the cases, we might not need those 14 pulls, but 14 pulls is the minimum number that will assure you that the socks pulled have a blue pair of socks.
If the conditions are not worst, we would be lucky and that
Thus, the smallest number of socks to pull out to be assured that we get a blue pair of socks is 14. (Option A is correct).

Answer:
s=6
Step-by-step explanation:
first you distribute the 8
8s+24=72
Then subtract 24 from both sides
8s=48
then divide both sides by 8 to get

obs:pra transformar em graus pra minutos deve-se multiplicar por 60
a) 21 400 b) 15 800 c) 10 400 d) 10 800
Answer:
d) 10 800
Step-by-step explanation:
Um ângulo é considerado raso quando sua medida é exatamente 180 graus, visto que cada grau equivale a 60 minutos, para obter a medida de um ângulo raso em minutos basta multiplicar 180 por 60:
[tex]180 *60=10800\ minutos[/tex]
A resposta correta é d) 10 800.
In a recent election Corrine Brown received 13 comma 482 more votes than Bill Randall. If the total number of votes was 120 comma 306, find the number of votes for each candidate.
Corrine Brown received
how many votes?
Answer:
53,412 and 66,894
Step-by-step explanation:
In this question we have to assume the things
Let us assume
Bill randall be X
So, the Corrine Brown is X + 13,482 as the corrine brown received 13,482 more votes than the Bill Randall
And, the total number of votes is 120,306
Now the equation is
X + X + 13,482 = 120,306
2X + 13,482 = 120,306
2X = 106824
X = 53,412 i.e Bill randall
And, the corrine brown is
= 13,482 + 53,412
= 66,894
A student is saving at least $5,000 for college. She begins with a savings account set up by her parents containing $2,000. Each month she deposits an additional $50 into the account. Fill in the first blank with the correct expressions that make the statement true.
(Attached is the statement and the choices)
This is the first box only!! Pls help!!! Giving 15-20 points!!!
Answer:
5000 ≥ 2000 + 50a
Step-by-step explanation:
She wants to save at least $5000 for college. The saving account set up by her parents already contains $2000 . This means she has more $3000 to save to meet her minimum target. Each month she saves $50 into the account.
Let
number of month = a
The information can be expressed as follows
5000 ≥ 2000 + 50a
The savings will continue increasing every months because she always deposit $50 every month.
Using the expression
5000 ≥ 2000 + 50a
minus 2000 from both sides
3000 ≥ 50a
divide both sides by 50
3000/50 ≥ a
60 ≥ a
This means she needs at least 60 months to meet her savings/target.

Solving similar triangles can someone please answer help
Answer:
k=3
Step-by-step explanation:
Since we know for a fact, thanks to it being given in your question, that the triangles are similar, that means the lengths are proportionate.
Secondly, you should notice a trend between both shapes. ΔPQRs sides are half of ΔDEFs.
With that in mind, we can conclude that for side K, it's half of 6, so 3! :D

A meteorologist measured the average rainfall received in Cities A and B. Both cities received
11inches of rainfall in total. While City A received x inches of rain, City B experienced three times
the amount of rainfall than City A.
Answer: x + 3x = 11
Step-by-step explanation:
Two cities A and B
Both cities receive 11 inches of rainfall in total
Amount of Rainfall in inches received by city A = x
Amount of Rainfall in inches received by city B = 3x
Therefore given the details above, total rainfall is best expressed using the equation ;
Rainfall in city A + Rainfall in city B = 11 inches
x + 3x = 11

find the difference between the first and second hour earnings to get 10.
get the difference of the second and third to get 12.
we realize that they are in increasing with even numbers from 10 going further, ie, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28....etc
to get the total earnings for the 24 hrs, you have to keep on adding the next even number till you reach the 24th hour
you will get $786.

Find the area of this shape. The area of this shape is _______ square centimeters.
Answer:
Step-by-step explanation:
area =(4+4+4)/2×2+1/2×(4+4)×5.75
=12+23.00
=35 sq.cms.
Step-by-step explanation:
Area of triangle = [tex]\frac{1}{2}[/tex](b*h)
Area of rectangle = b*h
[tex]A(big-triangle) = \frac{1}{2} (5.75*4)[/tex]
[tex]A(big-triangle) = \frac{1}{2}(23)[/tex]
[tex]A(big-triangle) = 11.5[/tex]
Since there are two big triangles, then we can multiply 11.5 by 2.
11.5 * 2 = 23
[tex]A(small-triangle) = \frac{1}{2}(2*2)[/tex]
[tex]A(small-triangle) = \frac{1}{2} (4)[/tex]
[tex]A(small-triangle) = 2[/tex]
Since there are two small triangles, then we can multiply 2 by 2.
2 * 2 = 4
[tex]A(rectangle)= 4 * 2[/tex]
[tex]A(rectangle) = 8[/tex]
Now, we can add up all of the areas so we can find the total area of the entire shape.
23 + 4 + 8 = 35
So, the area of the entire shape is 35 square cm.

A locker combination consists of two non-zero digits. The digits in a combination are not repeated and range from 2 through 9.
Event A = the first digit is an odd number
Event B = the second digit is an odd number
If a combination is picked at random with each possible locker combination being equally likely, what is P(B|A) expressed in simplest form?
A. 3/8
B. 3/7
C. 1/2
D. 4/7
Answer:
3/7 (b)
Step-by-step explanation:
If a combination is picked at random with each possible locker combination being equally likely, the conditional probability P(B|A) is 3/7.
What is conditional probability?Conditional probability is defined as the likelihood of an event or outcome occurring, based on the occurrence of a previous event or outcome.
Probability of event A = P(the first digit is an odd number) = 4/8
Given that event A has already occurred, we need to calculate the probability of the occurrence of probability B.
The total possible outcomes are 7 (out of 8 one is used up in event A).
Favorable outcomes are 3 (out of 4 one is used up in event A).
P(B|A) = 3/7
