Answer:
[tex]a_{n} = 12 -3(n-1)[/tex]
Step-by-step explanation:
[tex]a_{1} = 12\\a_{n} = a_{n-1} - 3[/tex]
we have to find formula for nth term of series for this problem
[tex]a_{1} = 12\\a_{2} = a_{2-1} - 3 = a_{1} -3 = 12 -3 = 9\\a_{3} = a_{3-1} - 3 = a_{2} -3 = 9 -3 = 6[/tex]
Thus, we see series is 12, 9 ,6
Thus, we can see that series is decreasing by unit of 3.
and we know that when there is in increase or decrease in series by a a constant number then series is arithmetic progression series.
Hence, this is a decreasing AP series
In AP
nth term is given
nth term = a+(n-1)d
where a is the first term
d is the common difference
common difference is given by = nth term - (n-)th term
lets take 2nd and 1st term to get common difference.
d = 9-12 = -3
(note: this was obvious by looking at series itself that d is -3 as series was decreasing by 3 unit)
a = 12
thus, nth term = a +(n-1)d
nth term = 12 +(n-1)(-3)
nth term = 12 -3(n-1)
writing this in form of [tex]a_{n}[/tex]
[tex]a_{n} = 12 -3(n-1)[/tex] Answer
The table below shows the possible outcomes of rolling a six-sided number cube and flipping a coin. What is the probability of getting a number less than 3 and a tails?
Answer: the probability of getting a number less than 3 and tails is P 1/6
Step-by-step explanation:
Assuming that the dice and the coin are normal ones, we can expect that the probability for each outcome is about the same.
For the coin we have 2 outcomes, heads and tails, then each outcome has a probability of 1/2
The dice has 6 outcomes, and each outcome has a probability of 1/6.
Then the probability of rolling a number less than 3 is equal to the probability of rolling a 1 plus the probability of rolling a 2.
P1 + P2 = 1/6 + 1/6 = 2/6 = 1/3.
The probability of getting tails with the coin is 1/2.
Now, the joint for both events is equal to the product of the probabilities of each event, this is:
P = (1/3)*(1/2) = 1/6
Answer:
1/6

Ming took a cab across town. His fare was $ 2 2 $22dollar sign, 22, and he leaves an 1 8 % 18%18, percent tip. What is the total amount Ming pays the cab driver?
Answer: $25.96
Step-by-step explanation:
Fare = $22
Percent tip = 18%
Hi, to answer this question, first we have to multiply the fare paid by the tip percentage in decimal form (divided by 100 ):
Mathematically speaking:
22x (18/100) = 22 x 0.18 = $3.96 (tip amount)
Finally, we have to add the tip amount and the fare:
22 +3.96 = $25.96
Feel free to ask for more if needed or if you did not understand something.
Answer:
ur answer is in the calculator
$25.96
Step-by-step explanation:
multiply $22 by 1.18 or 118 percent

Find the surface area of a cylinder with radius r = 6 and height h = 14.8 to the nearest tenth of a square cm. Use π = 3.14
Answer:
783.7 square units
Step-by-step explanation:
The formula for the surface area of a cylinder is ...
A = 2πr^2 + 2πrh = 2πr(r +h)
Using the given numbers, the area is ...
A = 2(3.14)(6)(6 +14.8) = 783.7 . . . square units
Answer:
About 783.7 square cm.
Step-by-step explanation:
The formula for the surface area of a cylinder is (2 * pi *r^2) + (2 * pi * r * h).
(2 * 3.14 * 6^2) + (2 * 3.14 * 6 * 14.8) = (2 * 3.14 * 36) + (2 * 3.14 * 6 * 14.8) = 6.28 * 36 + 6.28 * 88.8 = 226.08 + 557.664 = 783.744.
So, the surface area of the cylinder is about 783.7 square centimetres.

If a candy box has a base which is 10 cm long and 8 cm wide, with a height of 5 cm, find out how much cardboard is needed to make the box.
Answer:
400cm³ of cardboard is required to make the box
Step-by-step explanation:
Hello,
To find the the size of cardboard required to make the box we need to know the shape of the box. This is to enable us calculate the volume of the box.
Data;
Length = 10cm
Width = 8cm
Height = 5cm
This dimension corresponds to that of a cubiod.
Volume of a cubiod = length × width × height
Volume of the box = 10 × 8 × 5
Volume of the box = 400cm³
The volume of the box is 400cm³
About 400cm³ of cardboard is needed to make the box
First, he needs to run to the store. To get to the store from his apartment, he can walk 1.2 miles North and 0.5 miles East along the sidewalks. Or, he can cut through the city to get from his apartment to the store along a single straight line. Walking on the sidewalks, Henry walks 6 miles/hour. Cutting through the city, Henry can only walk 3.5 miles/hour.
Answer:
If Henry walks along the sidewalks, he will walk 1.7 miles in total. It will take him 17 minutes to reach the store and another 17 minutes to come back.
If Henry cuts through the city, he will walk √(1.2² + 0.5²) = 1.3 miles in total. It will take him 22.3 minutes to reach the store and another 22.3 minutes to come back.
Even though Henry will need to walk a longer distance if he walks along the sidewalks, he will be able to reach the store and back back in a shorter time than if he cuts through the city.
Which of the following represents the translation of M (8,-2) along vector<-5, 1 > and its reflection
across the y-axis?
Step-by-step explanation:
M(8.-2), M'(x,y) , [tex]$$\overrightarrow{v}[/tex] =(-5,1)
[tex]$$\overrightarrow{MM'} = $$\overrightarrow{v}[/tex]
--> x - 8 = -5 --> x= 3
---> y+2 = 1 --> y =-1
so M'(3,-1) and its reflection y-axis is (-3,-1)
The correct representation of given transformations is [tex]\bold{M(8,-2)\rightarrow M'(3,-1)\rightarrow M''(-3,-1)}[/tex]
What is translation?"A translation is a geometric transformation where a geometrical figure is moved from one location to another location without changing its size, shape or orientation."
What is vector?"A vector is a quantity or phenomenon that has magnitude and direction."
To find the vector from point P(a ,b) and Q(m, n)
[tex]\overrightarrow{PQ}= < m-a,n-b >[/tex]
We have been given that, the translation of M (8,-2) along vector<-5, 1 >
Let (x, y) represents the translated point along <-5, 1>
This means, <-5, 1> = <x-8, y-(-2)>
⇒ x - 8 = -5
⇒ x = -5 + 8
⇒ x = 3
Also, y + 2 = 1
⇒ y = 1 - 2
⇒ y = -1
So, the translated point is (3, -1)
The reflection of (3, -1) along y-axis is (-3, -1) .
Hence the correct representation of transformations is[tex]\bold{M(8,-2)\rightarrow M'(3,-1)\rightarrow M''(-3,-1)}[/tex] that is, option (C)

Fairview High School has an anime (Japanese animation) club that any
student can attend. The relative frequency table shows the proportion of
students in the high school who take Japanese and/or are in the anime club.
You have the correct answer.
=======================================================
Explanation:
Focus solely on the "in anime club" row. We do this because of the phrasing "given the student is in the anime club". We know for a fact that whoever is randomly picked, they are in the anime club. So we don't have to worry about other data values in the other rows.
Divide the value 0.13 which is in the "takes Japanese" column over 0.14, which is in the "total" column.
Basically we're computing [tex]P(A|B) = \frac{P(A \cap B)}{P(B)}[/tex] where A and B represent the events "takes Japanese" and "in anime club" respectively. The upside down U symbol represents intersection to indicate both events are happening at the same time.
So we end up with 0.13/0.14 = 0.92857142857142 which rounds to 0.93, then that converts to 93% when you move the decimal point over to the right two spots.

A survey of 900 randomly selected high school students determined that 422 play organized sports. (a) What is the probability that a randomly selected high school student plays organized sports? (b) Interpret this probability.
Answer:
P = 0.4688 = 46.88%
The probability that a randomly selected high school student plays organized sports is 0.4688.
Step-by-step explanation:
We are given that a survey of 900 randomly selected high school students determined that 422 play organized sports.
(a) What is the probability that a randomly selected high school student plays organized sports?
We know that the probability of an event is given by
P = Number of desired outcomes/total number of outcomes
For the given case, the desired outcomes are those students who play organized sports and the total number of outcomes are 900 randomly selected high school students who were surveyed.
So the probabilty is
P = 422/900
P = 0.4688
P = 46.88%
(b) Interpret this probability
There is a 46.88% chance of randomly selecting a high school student who plays organized sports or in other words, if we randomly choose a high school student then there is a 46.88% probability that the selected student plays organized sports.

Joe and Nate went for a walk. The system representing each boy’s progress is graphed below. A graph titled Joe and Nate's progress has minutes since noon on the x-axis and miles from Joe's house on the y-axis. A line labeled Joe's progress goes through (10, 1) and (20, 2). A line labeled Nate's Progress goes through (0, 5) and (30, 3). Which statements about the system and scenario are true? Check all that apply. Nate starts 5 miles away from Joe’s house and gets closer as he walks because the y-intercept is 5 and his distance is decreasing. Nate walks at a negative speed because the slope of his line is negative. Joe walks at 1 mile per hour because the line representing his progress rises 1 for every 1 it runs. Nate walks at rate of 2 miles every 30 minutes because the difference in distance is 2 miles for every 30 minutes of time. Joe is walking faster than Nate because his line is steeper, meaning the distance he travels is changing more quickly.

A child reshapes a cone made up of China clay of height 24 and radius 6 into a sphere.
The radius of the sphere is...
Answer:
6
Step-by-step explanation:
Volume of the cone = V=πr2h ^3=π·62·24 ^3≈904.77868
So, the volume of the sphere, will be the same too:
904.78 = 4/3 x pi x r^3
Solve:
904.78 = 4.18 x r^3
r^3 = 904.78 divided by 4.18
r^3 = 216.45
r = cube root of 216(approximate) = 6.

This grid follows two rules.
Rule 1 The sums of each row are equal.
Rule 2 The products of each column are equal.
The grid below follows the same two rules.
Work out the missing numbers.
a =
b =
c =
d =
Answer:
a = 4,
b = 12
c = 10
d = 15
Step-by-step explanation:
Since the product of each column is equal, therefore,
b*5 = 60
b = 60 ÷ 5 = 12
c*6 = 60
c = 60 ÷ 6 = 10
Since the sum of each column are equal, therefore,
12 + 10 + a = 5 + 6 + d
22 + a = 11 + d
Think of a number you can add to 22, and another number you can add to 11, which will make both sides equal. Add both numbers, whenmultiplied together should give you 60.
Factors of 60 are:
(a, d)
(1, 60) => 22 + a = 11 + d => 22+1 = 11+60 (incorrect)
(2, 30) => 22 + a = 11 + d => 22+2 = 11+30 (incorrect)
(3, 20) => 22 + a = 11 + d => 22+3 = 21+20 (incorrect)
(4, 15) => 22 + a = 11 + d => 22+4 = 11+15 => 26 = 26 [CORRECT]
(5, 12) => 22 + a = 11 + d => 22+5 = 11+12 (incorrect)
(6, 10) => 22 + a = 11 + d => 22+6 = 11+10 (incorrect)
Therefore,
a = 4,
d = 15

the area of the sector can be rounded to [tex]92.2\,\,in^2[/tex]
Step-by-step explanation:
Use the fraction of the area of the circle associated with the red sector. Use a proportion to find the appropriate fraction knowing that a full circle [tex](360^o)[/tex] corresponds to the area:
[tex]Area=\pi\,R^2=\pi\, (8\,in)^2= 64\, \pi\,\,in^2[/tex]
then the proportion goes like:
[tex]\frac{64\,\pi\,\,in^2}{360^o} =\frac{sector}{165^o} \\ sector=\frac{64\,\pi\,165^o}{360^o}\,\,in^2\\sector\approx 92.15\,\,in^2[/tex]
Therefore, the area of the sector can be rounded to [tex]92.2\,\,in^2[/tex]

. A law firm is run by four partners (A; B; C; D) . Each partner has one vote and decisions are made by majority rule, but in the case of a 2-2 tie, the coalition with A (the senior partner) wins.
Answer:
1) (ABCD) (ABC) (ABD) (ACD) (BCD) (AB) (AC) (AD)
2) A= 0.5000; B = 0.1667; C = 0.1667; D = 0.1667
Step-by-step explanation:
The questions are missing and should be
1) List all the winning coalitions in this voting system and the critical players in each.
2) Find the Banzhaf power index of this law firm.
1) Any combination of three partners, four partners, or a combination with two partners containing A is a winning coalition:
(ABCD) (ABC) (ABD) (ACD) (BCD) (AB) (AC) (AD)
2) The Banzhaf power index for each partner is given by the number of outcomes that said partner has a swing vote, divided by the number of possible swing vote situations.
Partners B, C, D will only have swing votes (change the outcome of the voting) when they are all in the same coalition, or when they are alone in a coalition with partner A:
[tex]B_B=2\\B_C=2\\B_D=2[/tex]
As for partner A, they will only be powerless to change the outcome when all of the other partners are in the same coalition (2 out of 8 possible combinations):
[tex]B_A=6\\[/tex]
The Banzhaf power index for each partner is:
[tex]B=\frac{2}{2+2+2+6}=0.1667\\C=\frac{2}{2+2+2+6}=0.1667 \\D=\frac{2}{2+2+2+6}=0.1667 \\A=\frac{6}{2+2+2+6}=0.5000[/tex]
