BRAINLIEST TO FIRST ANSWER PLEASEEE HELPPP!!! The dance team has 9 dancers to perform different roles in each performance. The probability that the team selects the same order as last performance is 1 divided by 362880 . Explain where each the numerator and denominator come from. What is the probability that the team puts the top hip hop dancer in the third position and top break dancer in the first position? Assume these are not the same people. Create a question, related to the dancers, where you use the indirect method, n(A’), to solve.
Answers
Answer:
P = 1 /362880
Where the numerator is the event of selecting the same order as last performance that is 1.
The denominator is the total number of possible events of selecting the 9 dancers.
p = 1/72
Therefore, there is a 1/72 probability that the team puts the top hip hop dancer in the third position and top break dancer in the first position.
Step-by-step explanation:
The probability that the team selects the same order as last performance is 1 divided by 362880
Explain where each the numerator and denominator come from
The probability that the team selects the same order as last performance is
P = 1 /362880
Where the numerator is the event of selecting the same order as last performance that is 1.
The denominator is the total number of possible events of selecting the 9 dancers.
Total number of dancers = 9
The 1st dancer can be selected in 9 ways
The 2nd dancer can be selected in 8 ways
The 3rd dancer can be selected in 7 ways
The 4th dancer can be selected in 6 ways
The 5th dancer can be selected in 5 ways
The 6th dancer can be selected in 4 ways
The 7th dancer can be selected in 3 ways
The 8th dancer can be selected in 2 ways
The 9th dancer can be selected in 1 ways
So the total number of ways = 9×8×7×6×5×4×3×2×1 = 362880
What is the probability that the team puts the top hip hop dancer in the third position and top break dancer in the first position?
Lets us put the top hip hop dancer in the third position and top break dancer in the first position then the remaining 7 dancers can be selected in
7×6×5×4×3×2×1 = 5040 ways
So the required probability is,
P = 5040/362880
P = 1/72
P = 0.0139
Therefore, there is a 1/72 probability that the team puts the top hip hop dancer in the third position and top break dancer in the first position.
If f(x) = 1 – x, which value is equivalent to |f(i)|?l
Answers
Answer:
Square root ( 2 )
Step-by-step explanation:
We have to determine which value is equivalent to | f ( i ) | if the function is: f ( x ) = 1 - x. We know that for the complex number: z = a + b i , the absolute value is: | z | = sqrt( a^2 + b^2 ). In this case: | f ( i )| = | 1 - i |. So: a = 1, b = - 1. | f ( i ) | = sqrt ( 1^2 + ( - 1 )^2) = sqrt ( 1 + 1 ) = sqrt ( 2 ).

Only need answer yo question number 30,14,10 pleassse
Answers
Answer:
See below in bold.
Step-by-step explanation:
14. f(x) = x^6 e^x
Applying the Product Rule:
f'(x) = x^6 e^x + 6x^5 e^x
= e^x(x^6 + 6x^5).
10. f(x) = x^3 - 4
y = x^3 - 4
x^3 = y + 4
x = ∛(y + 4) so:
f-1(x) = ∛(x + 4). (you are correct.)

There are several sets of different numbers which can be chosen from {0,1,2,3,4,5,6,7,8,9}. How many of these sets contain any 5 numbers?
Answers
Answer:
252 sets
Step-by-step explanation:
The set given to us is:
{0,1,2,3,4,5,6,7,8,9}
Total number of elements in set = n = 10
Number of elements to be included in seach set = r = 5
As the order doesn't matter, we can use the combination formula to find number of different combinations if we choose 5 numbers from the given 10 numbers with no repetition:
C(10,5) = 10!/(5!)(10-5)!
C(10,5) = 10!/(5!)(5!)
C(10,5) = 10·9·8·7·6/ 5·4·3·2·1
C(10,5) = 252
Thus 252 sets can be formed which contains any of the 5 numbers from the sets

x = -3.75
Step-by-step explanation:
First, combine like terms:
x - 5x = -4x
-4x = 15
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide -4 from both sides:
(-4x)/-4 = (15)/-4
x = 15/-4
x = -3.75
-3.75 is your answer for x.

Suppose that alpha is inversely proportional to beta. If alpha = -6 when beta = 12, find alpha when beta = -2.
Answers
Answer:
36
Step-by-step explanation:
Equation for an inversely proportional relation, where y is inversely proportional to x:
[tex] y = \dfrac{k}{x} [/tex]
Here we have:
[tex] \alpha = \dfrac{k}{\beta} [/tex]
We use the known ordered pair to find k.
[tex] -6 = \dfrac{k}{12} [/tex]
[tex] k = -72 [/tex]
The relation is:
[tex] \alpha = \dfrac{-72}{\beta} [/tex]
For beta = -2,
[tex] \alpha = \dfrac{-72}{-2} [/tex]
[tex] \alpha = 36 [/tex]

In which quadrants do solutions for the inequality y is less than or equal to two sevenths times x plus 1 exist?
Answers
Answer:
y will be in every single quadrant
Step-by-step explanation:
So we have the equation [tex]y\leq \frac{2}{7} x+1[/tex] first we will have to look at the equation. It says that y is less than or equal to [tex]\frac{2}{7} x+1[/tex] since y is less than [tex]\frac{2}{7} x+1[/tex] the only place the shaded area where y can be is under the line that is drawn be the equation. When the equation is graphed the y-intercept will be on positive 1 it since slope is rise over run it will look something like the file attached to this. so under the line you can see every single quadrant so that is why it would be that way

SOMEONE PLEASEEEEE HELLPPP !! The diameters of Breaburn apples are normally distributed with a mean of 8.2cm and a standard deviation of 2.8cm. If you had a shipment of 2000 apples, how many apples would have a diameter: a) smaller than 5.9cm? b) larger than 10.2cm?
Answers
Answer:
a. 412
b. 478
Step-by-step explanation:
We have to find the corresponding probabilities using the standard normal table, that is, we must calculate the value of z, the formula of z is as follows:
z = (x - m) / sd
where x is the value to evaluate, m is the mean and sd is the standard deviation.
We are told that the mean is 8.2 cm and the standard deviation is equal to 2.8 cm.
a. smaller than 5.9cm?
In this case x would be 5.9, we replace and we are left with:
z = (x - m) / sd
z = (5.9 - 8.2) /2.8
z = -0.82
If we look for this value in the normal table (attached) it corresponds to 0.2061, to know the number of apples we must multiply this value by the total value of apples, that is 2000. Therefore:
2000 * 0.2061 = 412.2 = 412
b) larger than 10.2cm?
In this case x would be 10.2, we replace and we are left with:
z = (x - m) / sd
z = (10.2 - 8.2) /2.8
z = 0.71
In this case z corresponds to 0.7611, but since this is the value is smaller than 10.2, and we need is larger than 10.2cm, it would be the complement, that is:
1 - 0.7611 = 0.2389
Now to calculate the total number of apples we have:
2000 * 0.2389 = 477.8 = 478
Find two consecutive odd whole numbers whose sum is two less than six times the first number.
Answers
Answer:
1, 3
Step-by-step explanation:
1st number = x
2nd number = x+2
x+x+2=6x-2
2x+2=6x-2
4=4x
x=1
so the first number is 1 and the second number is 3.
CHECK: The sum of one and three is four, which is two less than six times one.
Consecutive odd numbers will be
2k + 1 and 2k + 3
Formulating the equation from the question
(2k + 1 + 2k + 3) = 6(2k+1) -2
4K + 4 = 12k + 6 -2
4= 8k + 4
K = 0
Therefore first odd number is 2k + 1 = (2 x 0) + 1 = 1
Second odd number is 2k + 3 = (2 x 0) + 3 = 3
The two numbers are 1 and 3

Step-by-step explanation:
We want to khow what is the size of the angle that coresponds 36 percent
we can state :
360 degree ⇒100 percent x (the angle we are looking for)⇒ 36 percent using the proportionality relation : x= (360*36)/100x = 129.6° round it x= 130°What is the equation of the line that is parallel to the given line and passes through the point (12, −2)? y = –Six-fifths x + 10 y = –Six-fifths x + 12 y = –Five-sixths x – 10 y = Five-sixths x – 12
Answers
Answer:
y = Five-sixths x – 12
Step-by-step explanation:
In the picture attached, the given line is shown. Its slope is:
m = [6 - (-4)]/[12 - 0] = 5/6
The line that is parallel to the given line has the same slope.
A line with slope m that pass through (x1, y1) satisfies:
y - y1 = m(x - x1)
Replacing with m = 5/6 and point (12, -2):
y - (-2) = 5/6(x - 12)
y + 2 = 5/6x - 10
y = 5/6x - 10 - 2
y = 5/6x - 12

Aram's four children are now 1, 5, 7, and 9 years old. In how many years will the sum of the ages of two of his children be twice the sum of the ages of the other two children?
Answers
Answer:
In 2 years
Step-by-step explanation:
age right now 1,5,7,9
Let the number of years in which the sum of the ages of two of his children be twice the sum of the ages of the other two children=x
Therefore Age of the children after x years will be 1+x,5+x,7+x and 9+x
2[1+x + 5+x] = (7+x)+(9+x)
2[6+2x]= 7+9+x+x
12+4x=16+2x
4x-2x=16-12
2x=4
x=4/2=2
Let's verify if the answer is correct
-- Verify by substituting the value of x in this 2[1+x + 5+x] = (7+x)+(9+x)
2[1+2 + 5+2] = (7+2)+(9+2)
2[10]=9+11
20=20
Therefore 2 years is the answer
We are required to find the number of years when the ages of two of his children be twice the sum of the ages of the other two children?
The number of years it will take for two of his children be twice the sum of the ages of the other two children is 2 years
Child 1 = 1 year
Child 2 = 5 years
Child 3 = 7 years
Child 4 = 9 years
let
x = number of years it will take for two of his children be twice the sum of the ages of the other two children
twice the age of the two younger children in the unknown year equal the age of the two older children in the unknown year
2{(1 + x) + (5 + x)} = (7 + x) + (9 + x)
2(1 + x + 5 + x) = 7 + x + 9 + x
2(6 + 2x) = 16 + 2x
12 + 4x = 16 + 2x
12 - 16 = 2x - 4x
-4 = - 2x
divide both sides by -2
-4 / -2 = x
x = 2
Therefore,
The number of years it will take for two of his children be twice the sum of the ages of the other two children is 2 years

Answer:

Step-by-step explanation:
whenever a line is horizontal and straight across the plane the slope is 0
Answer:
m = 0
Step-by-step explanation:
slope can be found using the following equation:
m (slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (-3 , -2)
(x₂ , y₂) = (1 , -2)
Plug in the corresponding numbers to the corresponding variables:
m = (y₂ - y₁)/(x₂ - x₁) = (-2 - (-2))/(1 - (-3))
Simplify:
m = (-2 - (-2))/(1 - (-3)) = (-2 (+2))/(1 +3) = (-2 + 2)/(1 + 3)
m = (-2 + 2)/(1 + 3) = (0)/(4)
m = 0/4 = 0
The slope of the line is 0.
