Answer:
1 7 21 35 35 21 7 1
Step-by-step explanation:
Pascal triangle is a mathematical expression that can be used to expand questions involving bracket, especially of high degree/ power. Example: [tex](a + b)^{9}[/tex] etc
For the given question, the Pascal triangle for the expansion is: 1 7 21 35 35 21 7 1
So that,
[tex](2x^{3}+3y^{2}) ^{7}[/tex] = 1.[tex](2x^{3}) ^{7}[/tex] + 7.[tex](2x^{3}) ^{6}[/tex].[tex]3y^{2}[/tex] + 21. [tex](2x^{3}) ^{5}[/tex].[tex](3y^{2}) ^{2}[/tex] + 35.[tex](2x^{3}) ^{4}[/tex].[tex](3y^{2}) ^{3}[/tex] + 35. [tex](2x^{3}) ^{3}[/tex].[tex](3y^{2}) ^{4}[/tex] + 21. [tex](2x^{3}) ^{2}[/tex].[tex](3y^{2})^{5}[/tex] + 7.[tex](2x^{3} )^{1}[/tex].[tex](3y^{2} )^{6}[/tex] + 1.[tex](3y^{2}) ^{7}[/tex]
= 128[tex]x^{21}[/tex] + 1344[tex]x^{18}[/tex][tex]y^{2}[/tex] + 6048[tex]x^{15}[/tex][tex]y^{4}[/tex] + 15120[tex]x^{12}[/tex][tex]y^{6}[/tex] + 22680[tex]x^{9}[/tex][tex]y^{8}[/tex] + 20412[tex]x^{6}[/tex][tex]y^{10}[/tex] + 10206[tex]x^{3}[/tex][tex]y^{12}[/tex] + 2187[tex]y^{14}[/tex]
Therefore;
[tex](2x^{3}+3y^{2}) ^{7}[/tex] = 128[tex]x^{21}[/tex] + 1344[tex]x^{18}[/tex][tex]y^{2}[/tex] + 6048[tex]x^{15}[/tex][tex]y^{4}[/tex] + 15120[tex]x^{12}[/tex][tex]y^{6}[/tex] + 22680[tex]x^{9}[/tex][tex]y^{8}[/tex] + 20412[tex]x^{6}[/tex][tex]y^{10}[/tex] + 10206[tex]x^{3}[/tex][tex]y^{12}[/tex] + 2187[tex]y^{14}[/tex]

6 - 8x = 5x - 10x + 12
Please help I suck at math thank you
Answer:
I guess it's -2
Step-by-step explanation:
6-8x = 5x - 10x + 12
∴ 10x - 8x - 5x = 12 - 6
∴ 10x- 13x = 6
∴ - 3x = 6
∴ x = -6\3
∴ x = -2
Answer:
-2
Step-by-step explanation:
6-8x=5x-10x+12
5x-10x=-5x
=6-8x=-5x+12 MOVE -5x TO THE LEFT SIDE AND 6 TO THE RIGHT SIDE
= -8x+5x=12-6
= -3x=6
= -x=2

The CPU of a personal computer has a lifetime that is exponentially distributed with a mean lifetime of six years. You have owned this CPU for three years. a. What is the probability that the CPU fails in the next three years? b. Assume that your corporation has owned 10 CPUs for three years, and assume that the CPUs fail independently. What is the probability that at least one fails within the next three years?
Answer: 0.39 ; 0.993
Step-by-step explanation:
Given that:
Mean of exponential distribution = 6
Using poisson :
P(X =x)Probability of failure in next 3 years :
Number of occurrences λ = 1 / 6 = 0.1667
P(X < 3) = 1 - e^-λx
P(X < 3) = 1 - e^-0.1667*3
P(X < 3) = (1 - e^-0.5)
P(X < 3) = 1 - 0.60653
P(X < 3) = 0.39346
= 0.393
B.)
Number of pc owned = 10 ; n = 10
P(atleast 1 fails) :
P(X ≥ 3)^n = 1 - [1 - P(X < 3)] ^n
P(X ≥ 3)^n = 1 - (1 - 0.393)^10
P(X ≥ 3)^n = 1 - 0.607^10
= 1 - 0.00679
= 0.993
This question is based on the probability. Therefore, the probability that the CPU fails in the next three years is 0.393 and the probability that at least one fails within the next three years is 0.993.
Given:
The CPU of a personal computer has a lifetime that is exponentially distributed with a mean lifetime of six years. You have owned this CPU for three years.
(a) We need to determined the probability that the CPU fails in the next three year.
It is given that, mean of exponential distribution = 6
By using Poisson distribution:
P(X =x) Probability of failure in next 3 years :
[tex]Number\, of \,occurrences\, \lambda = \dfrac{1}{6} = 0.1667[/tex]
[tex]P(X < 3) = 1 - e^{-\lambda x}\\P(X < 3) = 1 - e^{-0.1667\times 3}\\P(X < 3) = (1 - e^{-0.5})\\P(X < 3) = 1 - 0.60653\\P(X < 3) = 0.39346= 0.393[/tex]
(b) We need to determined the probability that at least one fails within the next three years.
Number of pc owned = 10 ; n = 10
P(at least 1 fails) :
[tex]P(X \geq 3)^n = 1 - [1 - P(X < 3)] ^n\\P(X \geq 3)^n = 1 - (1 - 0.393)^{10}\\P(X \geq 3)^n = (1 - 0.607)^{10} = = 1 - 0.00679 = 0.993[/tex]
Therefore, the probability that the CPU fails in the next three years is 0.393 and the probability that at least one fails within the next three years is 0.993.

2x- y = -2
2x + 4y =8
Answer:
x=8
y=4
Step-by-step explanation:
Answer:
Your point would be: (0,2)
x = 0
y = 2
Step-by-step explanation:
This would be the case if you're looking for the point by solving with substitution, or any other methods, of the systems of equations.
In any case, you are looking to find either x or y first.
I will demonstrate with the 'y' value, since it is easier when cancelling out the 'x' value.
2x - y = -2
2x + 4y = 8
(I want to make one of the two equations negative, so that I can eliminate or cancel out the 'x' value(s)).
- (2x - y = -2) --> -2x + y = 2
2x +4y = 8
---------------------------------------
5y = 10
--- ---
5 5
------------
y = 2
(Reason for putting a negative in front of the equation '2x - y = -2' was made in order to eliminate the value(s) '2x' in both equation, and in order to do that, one equation must be negative, while the other is positive, for example:
x + 2y = 6
x + 3y = 5
(You can make any of these equations negative, but only one equation is needed to be negative for the value you want to cancel out,
DO NOT TRY AND CANCEL OUT BOTH X AND Y)
-(x + 2y = 6)
Turn into:
-x - 2y = -6
x + 3y = 5
---------------
y = -1
(Back to the Original Problem)
We now need to find the 'x' value(s):
4(2x - y = -2)
8x - 4y = -8
2x + 4y = 8
----------------
10x = 0
--- ---
10 10
----------------
x = 0
Your final answer will be:

What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that;
The ratio is,

Answer:
Step-by-step explanation:
P and Q are sunsets of the universal set U={n:1<n<10} and n is an integer. P consists of even numbers less than 7 and Q consists of prime numbers less than 10. List the elements of a)P'uQ' b)P'nQ' c)(P'nQ')' d)(PuQ)'
Part A
Answer: P' u Q' = {3,4,5,6,7,8,9}---------------------------------
Work Shown:
The universal set here is U = {2,3,4,5,6,7,8,9} so we're listing all the integers between 2 and 9. We don't include 1 or 10 since n is larger than 1, and smaller than 10.
P = even numbers less than 7, subset of U
P = {2,4,6,8}
P ' = {3,5,7,9}
Note how the set P' is the set of everything in U that is not in set P. It's the opposite of set P. We call this the complement of set P.
Q = prime numbers less than 10, subset of U
Q = {2,3,5,7}
Q ' = {4,6,8,9}
Applying the union set operation on the sets P' and Q' leads to
P' u Q' = {3,5,7,9, 4,6,8,9}
All I did was combine the two sets of numbers under one umbrella. From here we toss out the duplicate entry of 9. This next step is optional, but sorting the values is standard convention.
Doing all this leads to
P' u Q' = {3,4,5,6,7,8,9}
This set represents all the values that are in set P' or in set Q' or both.
=======================================================
Part B
Answer: P' n Q' = {9}---------------------------------
Work Shown:
Now we're looking at the intersection of sets P' and Q'
List out those sets
P ' = {3,5,7,9}
Q ' = {4,6,8,9}
We see that only the value 9 is in common
Therefore,
P' n Q' = {9}
=======================================================
Part C
Answer:
(P' n Q')' = {2,3,4,5,6,7,8}
---------------------------------
Work Shown:
You start with the result from part B. Then you erase that item (9) from the universal set. Everything in this answer set is not found in the set {9}
Put another way: we're finding the complement or opposite of P' n Q'
=======================================================
Part D
Answer: (P u Q)' = {9}---------------------------------
Work Shown:
P = {2,4,6,8}
Q = {2,3,5,7}
P u Q = {2,3,4,5,6,7,8}
Everything in set P u Q is either found in P, Q, or both. Any duplicates are tossed out.
Take the opposite of this to get
(P u Q)' = {9}
It is not a coincidence we get the same result as part B. It turns out that the two equations are true for any two sets P and Q
(P u Q)' = P' n Q'(P n Q)' = P' u Q'For more information, check out De Morgan's Laws. Use of a Venn Diagram may help visualize what is going on, so you can organize the values.

Question: State whether each table of values represents a function
Answer:
Please check the explanation.
Step-by-step explanation:
As we know that the values in the table represent a function only if there there is only 1 input for every output.
Given the table 1
x y
-12 2
-10 10
0 -2
5 -6
8 -11
15 -15
From the table, it is clear that for each input there exists a unique output.
i.e.
According to the given table,
y = 2 at x=-12
y = 10 at x=-1 0
y = -1 at x=0
y = -11 at x=8
y = -15 at x=15
From the table, it is clear that for each input x, it has a unique output y.
Hence, table 1 is a function.
Given the table 2
x y
9 -18
-20 0
-6 1
-17 16
9 17
11 19
This table does not produce a function, because the input x=9 produces two outputs.
i.e.
at x = 9, the y = -18
at x = 9, the y = 17
Therefore, the table 2 does not represent a function.
