Answer:
(a)
[tex]T_n = 3(-4)^{n-1}[/tex]
(b)
[tex]\sum\limits^n_1 { 3(-4)^{n-1}[/tex]
Step-by-step explanation:
Given
The above sequence
Solving (a): The explicit formula
The given sequence is a geometric sequence because the common ratio (r) is:
[tex]r = \frac{-12}{3} = \frac{48}{-12} = \frac{-192}{48} = \frac{768}{-192}[/tex]
[tex]r = -4[/tex]
The explicit formula is calculated using the n term of an GP.
[tex]T_n = ar^{n-1}[/tex]
[tex]T_n = 3 * (-4)^{n-1}[/tex]
[tex]T_n = 3(-4)^{n-1}[/tex]
Solving (b): Summation notation.
This implies that the sum of the sequence.
To do this, we write Tn inside the summation sign
i.e.
[tex]\sum\limits^n_1 {T_n}[/tex]
Substitute values for Tn
[tex]\sum\limits^n_1 { 3(-4)^{n-1}[/tex]
An airline reports that 85% of its flights arrive on time. To find the probability that its next four flights into LaGuardia Airport all arrive on time, can we multiply (0.85)(0.85)(0.85)(0.85)? Why or why not?
Answer:
The answer is "no".
Step-by-step explanation:
No, because the probability besides simultaneous flights to arrive on time are not self-sufficient for every flight (when the first flight was late, therefore the probabilities during the next flight were significantly greater), because then the standard multiplication principle would be used for explanatory variables.
Yes, we can multiply (0.85)(0.85)(0.85)(0.85)
Let the four flight be represented by A, B, C, and D respectively
Probability that each of the flights arrive on time is 0.85
That is:
Probability that flight A arrives on time, P(A) = 0.85
Probability that flight B arrives on time, P(B) = 0.85
Probability that flight C arrives on time, P(C) = 0.85
Probability that flight D arrives on time, P(D) = 0.85
Probability that the next four flights arrive on time will be:
P(A) x P(B) x P(C) x P(D) = 0.85 x 0.85 x 0.85 x 0.85
Yes, we can multiply (0.85)(0.85)(0.85)(0.85)

470 patrons showed up at the opening of a new movie. 20 patrons were turned away as the cinema with 18 rows of seats was filled to capacity. What was the average number of patrons in each row? Then management then arranges the seating area for the same capacity but in 15 rows instead. How many patrons will one row hold?
9514 1404 393
Answer:
25 seats per row in 18 rows30 seats per row in 15 rowsStep-by-step explanation:
The total number of seats is 470 -20 = 450.
The number of seats in a row is found by dividing seats by rows.
In 18 rows
450 seats/(18 rows) = 25 seats/row
In 15 rows
450 seats/(15 rows) = 30 seats/row
Answer:
Required Answer :-The total number of seats in the movie = 470 - 20 = 450
When 18 rows
450/18
25 patron
When 15 rows
450/15
30 patron

find area and perimeter
Answer: The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
Step-by-step explanation:
Find the surface area please!
Answer:
158 in²Step-by-step explanation:
First we can write the equation to find the surface area of a rectangular prism[tex]A = 2(w*l+h*l+h*w)[/tex]
Now rewrite filling in variables
[tex]A = 2(3*5+8*5+8*3)[/tex]
Solve. Keep in mind the order of operations
After solving, you should get 158.
Since these measurements were done in inches, we need to add inches/in to the end.
Also, since it is area, we need to add ²

In circle 0. ZROSTOU, RS = 12x + 4 and TU=112 + 15.
What is the length of TU?
Answer:
136
Step-by-step explanation:
12x + 4 = 11x + 15 {Subtract 11x from both sides.}
(12x - 11x) + 4 = 15
x + 4 = 15 {Subtract 4 from both sides.}
x = 15 - 4
x = 11
Now, SUBSTITUTE 11 for x in 11x + 15.
11(11) + 15
121 + 15
136 units
The length of line TU is 136 units.
A local cable TV/Internet/phone provider charges new customers $129 for all three services, per month, for the first year under their "3 for 129" promotion. Joanne normally
pays $74 for her monthly home phone service, $59 for Internet service, and $69 for cable television
a. What are her percent savings if she switches to the "3 for 1299 plan? Round to the nearest percent.
b. If, after the first year, the flat fee for all three services is $139, what are her percent savings? Round to the nearest percent.
Answer:
Step-by-step explanation:
Amount paid by Joanne before promotion = 74 + 59 + 69 = $ 202
a) Amount saved if she switches to "3 for 129 plan" = 202 - 129 = $ 73
Percentage of saving = [tex]\frac{73}{202}*100[/tex] = 36.13 = 36%
b) Amount saved after the first year = 202 - 139 = $ 63
Percentage of saving = [tex]\frac{63}{202}*100[/tex] = 31.18 = 31%

1 If it takes 48 hour to leak 8 liter water how many hour does it take to leak 15 liter water ? Show your steps .
2.If 7 kg potato is 140 $ how much kg can 340 $ buy ? Show your steps.
3.What is ratio.
Answer:
answer is 90 hr for question 1
Step-by-step explanation
48 hr 8 liter
? 15 liter
so what ur going to do is u criss-cross when u do u multipy 48 with 15 and 8 with "?" when u multiply 48 with 15 u get 720 and when you multiply 8 with "?" u get 8?
so it will look like this
720= 8?
let make "?" an "x" for a better understanding. so the reason we are making it an "x" is because we dont know the amount of hr it takes for 15 liters of water to leak.
let go back to the calculation.
so it will look something like this
720 = 8x
exactly the same thing but we made "?" an"x"
so now we divide both sides with 8. why? because we need "x" alone and want 8 to disappear
so when u divide both sides with 8 it will look something like this
780/8 =x
so when u divide 780 with 8 u get 90. so what does that mean? it means it takes 90 hr for 15 liters of water to leak.
do you understand?
