AS per the permutation concept, the number of ways can Alice win or draw exactly three times is 240

Permutation:

In probability, permutation refers the arrangement of objects in a definite order.

Given,

Alice and Bob are playing a game in which there are several rounds and each round can be a win, a loss, or a draw for Alice.

Here we need to find the number of ways can Alice win or draw exactly three times, if they play 6 rounds.

While we looking into the given question, we know that,

Total number of games = 6

Possible values = 3 ( win, loss, or draw)

Here we need to find the probability of winning 3 times, it can be calculated by using the permutation as,

=> 6! / (6 - 3)!

=> 6! / 3!

=> 120

Similarly, the the probability of draw 3 times, it can be calculated by using the permutation as,

=> 6!/ (6 - 3)!

=> 120

So, the number of ways can Alice win or draw exactly three times is

=> 120 + 120 =  240

For dimensions of x =10 and y=5 for the base and height that will make the tank weight as little as possible.

Here we are given the information of a square-based, open-top, rectangular steel holding tank, so here the tank is in the shape of a cuboid and we know  the formula  for :

volume = x*y*z, as  here it is a square base, so the volume will be

volume =  x²*y, where x and y are the dimension of the base and height

So for the  given reason,  

=>x²*y =  500

=> y = 500/x²

Again, the surface area formula  will be

S=x²+4xy, substituting the value of  y in this question

=>S=x²+4x(500/x²)

=>S=x²+2000/x

Differentiating the above formula with respect to x, we get

=>2x-2000/x²=0

=>2x³= 2000

=>x³= 1000

=>x =10

so the substituting the x values of x in  the equation y , we get

y = 500/x²

=>y = 5

so the dimensions are x= 10 and y=5

Given that,

To cover an area of his living room floor that is 8 1/3 feet wide by 10 feet long, Aurelio is buying carpet tiles. The dimensions of each carpet tile are 20 inches broad by 20 inches long.

We have to find how many carpet tiles will Aurelio need to buy at the very least to cover this portion of the floor in his living room.

We know that,

1 feet=12 inches.

So,

8 1/3 feet = 25/3 feet =100 inches.

10 feet =120 inches.

=100+120 inches

A z-score of 23.9 years must be located in the gorillas' lifespans in a specific zoo's typical normal distribution.

The equation can be used to determine the z score.

z = (x - μ)/σ

In which,

Then,

z = (23.9 - 20.8)/3.1

z = 1

According to the empirical rule, 68% of lifespans are within one standard deviation of the mean.

Half of it, 68/2 = 34% %, is on the right side of the mean's standard deviation.

Given that the likelihood of a gorilla lasting less than 23.9 years is 50%.

A gorilla's lifespan being less than the norm means is;

50% + 34% = 84% sits below z-score 1.

Answer:

3

Step-by-step explanation:

We know a cube has six sides.

Using this logic, we can divide 54 by 6.

54 ÷ 6 = 9

We can conclude that each side has 9 stickers.

If we think of a square, and the area of that square is 9,

3 × 3 = 9

The number of stickers in each row and column is 3

Answer:

3 stickers in each row and column

Step-by-step explanation:

so i divided 54 by 6 and that equals 9 and since you said there was the same number of stickers on each column and rows that would be 9 separated into a even amount of rows and columns would be 3

The correct answer is (C) since the limitations to depict this real-world problem in inequality are 75 < x < 110 and 0 < y ≤ 50.

The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. It is an illustration of inequity.

This shows that the left half, 5x 4, is bigger than the right part, 2x + 3.

So, our senior trip will be a group excursion to a beach.

Only when the temperature is between 75 and 110 degrees does the resort permit swimming.

On your excursion, there is space for 50 people.

Let y represent the number of travelers and x represent the temperature.

The temperature ranges from 75 to 110 degrees:

75 < x < 110  

On your excursion, there is space for 50 persons:

0 < y ≤ 50

Answer:

k = 14

Step-by-step explanation:

2(k+8) = 44

2*k + 2*8 = 44

2k + 16= 44

2k = 44 - 16

2k = 28

k = 28/2

k = 14

Check:

2(14+8) = 44

2*22 = 44

The final value of the product = 292

According to the given equation -

= (4a2+3b)x(4a2+36)

multiply the whole equation-

= 16a4+144+12a2b+108

as we can see that the values of a and b are given 1 and 2 respectively,

so putting the values of a and b in the equation we get -

= 16(1)4+144+12(1)2(2)+108

= 292

The product of the following equation will be = 292

f(2) = g(2) and f(0) = g(0) is representation of f(x) = g(x)

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

the curved red line represents g(x) and the straight blue line represents f(x) .

The important thing here is that the equality of functions f(x)=g(x) is represented as a common function between their curves. So, we just need to find such a common point for both.

f(x) has points (0, 4) and (2, 0).

g(x) has points (0,4) and (2,0).

Notice that both functions have the same y-value for x=0 and x=2, that means f(0)=g(0) and f(2)=g(2)

Hence, f(2) = g(2) and f(0) = g(0) is representation of f(x) = g(x)

The intervals on which the function f(x) = ax² + bx + c (where "a" doesn't = 0) is increasing and decreasing is x>-b/2a and x<-b/2a

Given that,

We have to find the intervals on which the function f(x) = ax² + bx + c (where "a" doesn't = 0) is increasing and decreasing.

We know that,

Take the function equation,

f(x)=ax² + bx + c

The derivative of the function of x is  

f'(x)=ax+b

So, f(x) is increasing when f'(x) > 0

f(x) is decreasing when f'(x) < 0

Then we can say

f'(x) > 0 , when  b > 0  and a < 0

2ax + b < 0

2ax < - b

x<-b/2a

Now,

f'(x) < 0 , when  b < 0  and a > 0

2ax + b > 0

2ax > - b

x>-b/2a

Therefore, the intervals on which the function f(x) = ax² + bx + c (where "a" doesn't = 0) is increasing and decreasing is x>-b/2a and x<-b/2a.
