The solutions for the given problems involving factorials and permutations are 8! = 40,320, 5P5 = 120, 8P4 = 1,680, 7P7 = 5,040 and the number of arrangement for 4 performers out of 9 is 3,024.

The subject here is mathematics, specifically factorials and permutations. Factorials are represented by the symbol '!'. The factorial of a number n is the product of all positive integers less than or equal to n. For example, 8! = 8*7*6*5*4*3*2*1 = 40,320.

Permutations refer to the number of ways a set of objects can be arranged. 'nPn' always equals to the factorial of n, therefore 5P5 equals to 5! = 5*4*3*2*1 = 120 and 7P7 equals to 7! = 7*6*5*4*3*2*1 = 5,040.

'nPm' equals to n factorial divided by (n-m) factorial. So, 8P4 equals to 8!/(8-4)! = (8*7*6*5)/1 = 1,680.

For the last question, the number of ways 4 performers can stand in a row out of 9, is calculated as a permutation of '9P4' (because the order of performers matters). Thus, it will be 9!/(9-4)! = 9*8*7*6 = 3,024.

Answer:

The first alternative is correct

Step-by-step explanation:

We move all the expressions to the left hand side of the inequality then combine like terms using lcm;

[tex]\frac{3}{1}+\frac{4}{x}-\frac{x+2}{x}\geq0\\\\\frac{3x+4-(x+2)}{x}\geq0\\\frac{2x+2}{x}\geq0[/tex]

Answer:

the first one

Step-by-step explanation:

Express the left side as a single fraction

3 + [tex]\frac{4}{x}[/tex]

= [tex]\frac{3x+4}{x}[/tex], hence

[tex]\frac{3x+4}{x}[/tex] ≥ [tex]\frac{x+2}{x}[/tex]

Subtract [tex]\frac{3x+4}{x}[/tex] from both sides

0 ≥ [tex]\frac{x+2}{x}[/tex] - [tex]\frac{3x+4}{x}[/tex]

0 ≥ [tex]\frac{-2x-2}{x}[/tex]

Multiply both sides by - 1, remembering to reverse the inequality symbol as a consequence

0 ≤ [tex]\frac{2x+2}{x}[/tex], hence

[tex]\frac{2x+2}{x}[/tex] ≥ 0

Answer: It is a function.

Step-by-step explanation:

By definition,  a function is a relation in which the input value (the x value) has one and only one output value (value of y).

The first number of each ordered pair is the input value and the second number of each ordered pair is the output value.

As you can see, the inputs value of the relation given in the problem have one and only one output value. Therefore, you can conclude that the relation is  a function.

Mrs. Eskew will have $1,841,395 left after subtracting the vacation expense of $278,389 from her initial savings of $2,119,784.

The student is asking how much money Mrs. Eskew will have left after spending part of her savings on a vacation. To find out, we simply need to subtract the amount spent on the vacation from the total amount she had saved. Mrs. Eskew started with $2,119,784 in the bank. After spending $278,389 on her vacation, we can calculate her remaining balance as follows:

$2,119,784 - $278,389 = $1,841,395.

Therefore, Mrs. Eskew will have $1,841,395 left after her vacation.

The graph is attached.

To graph a parabola we need to know the following:

- If the parabola is open upwards or downwards

- They axis intercepts (if they exist)

- The vertex position (point)

We are given the function:

[tex]f(t)=-16t^{2}+64t+4[/tex]

Where,

[tex]a=-16\\b=64\\c=4[/tex]

For this case, the coefficient of the quadratic term (a) is negative, it means that the parabola opens downwards.

Finding the axis interception points:

Making the function equal to 0, we can find the x-axis (t) intercepts, but since the equation is a function of the time, we will only consider the positive values, so:

[tex]f(t)=-16t^{2}+64t+4\\0=-16t^{2}+64t+4\\-16t^{2}+64t+4=0[/tex]

Using the quadratic equation:

[tex]\frac{-b+-\sqrt{b^{2}-4ac } }{2a}=\frac{-64+-\sqrt{64^{2}-4*-16*4} }{2*-16}\\\\\frac{-64+-\sqrt{64^{2}-4*-16*4} }{2*-16}=\frac{-64+-\sqrt{4096+256} }{-32}\\\\\frac{-64+-\sqrt{4096+256} }{-32}=\frac{-64+-(65.96) }{-32}\\\\t1=\frac{-64+(65.96) }{-32}=-0.06\\\\t2=\frac{-64-(65.96) }{-32}=4.0615[/tex]

So, at t=4.0615 the height of the softball will be 0.

Since we will work only with positive values of "x", since we are working with a function of time:

Let's start from "t" equals to 0 to "t" equals to 4.0615.

So, evaluating we have:

[tex]f(0)=-16(0)^{2}+64(0)+4=4\\\\f(1)=-16(1)^{2}+64(1)+4=52\\\\f(2)=-16(2)^{2}+64(2)+4=68\\\\f(3)=-16(3)^{2}+64(3)+4=52\\\\f(4.061)=-16(4.0615)^{2}+64(4.0615)+4=0.0034=0[/tex]

Finally, we can conclude that:

- The softball reach its maximum height at t equals to 2. (68 feet)

- The softball hits the ground at t equals to 4.0615 (0 feet)

- At t equals to 0, the height of the softball is equal to 4 feet.

Step-by-step explanation:

The total amount of sandwiches on the tray is 4+7+6. This makes 17. This will be the denominator of our fraction which we are going to use for the probability.

There are 7 ham sandwiches on the tray, therefore the probability that he will pick a ham sandwich is 7/17.

Brainliest? :)

Final answer:

The probability that Danny picked a ham sandwich is 7/17, since there are 7 ham sandwiches out of a total of 17 sandwiches on the tray.

Explanation:

The question is about calculating the probability that Danny picked a ham sandwich. To determine this, we count the total number of sandwiches and then count the number of ham sandwiches.

Total number of sandwiches = 4 turkey + 7 ham + 6 tuna = 17 sandwiches.

Since there are 7 ham sandwiches, the probability (P) that Danny picks a ham sandwich is calculated by dividing the number of ham sandwiches by the total number of sandwiches.
P(ham sandwich) = Number of ham sandwiches / Total number of sandwiches
P(ham sandwich) = 7 / 17

Therefore, the probability that Danny picked a ham sandwich is 7/17.

Answer: option B

Step-by-step explanation:

To solve this exercise you must apply the proccedure shown below:

- Apply the Distributive property (Remember that when you multiply two powers with the same base, you must add the exponents).

[tex]b^m*b^n=b^{(m+n)}[/tex]

- Add the like terms.

Therefore, you obtain that the product is:

[tex](x^2+3x+4)(3x^2-2x+1)=3x^4-2x^3+x^2+9x^3-6x^2+3x+12x^2-8x+4\\=3x^4+7x^3+7x^2-5x+4[/tex]

Answer:

B

Step-by-step explanation:

When multiplying [tex](x^2+3x+4)(3x^2-2x+1)[/tex], we can use the distributive property of multiplication over addition:

[tex](x^2+3x+4)(3x^2-2x+1)=x^2\cdot 3x^2+x^2\cdot (-2x)+x^2\cdot 1+3x\cdot 3x^2+3x\cdot (-2x)+3x\cdot 1+4\cdot 3x^2+4\cdot (-2x)+4\cdot 1=3x^4-2x^3+x^2+9x^3-6x^2+3x+12x^2-8x+4.[/tex]

Now group the like terms:

[tex]3x^4-2x^3+x^2+9x^3-6x^2+3x+12x^2-8x+4=3x^4+(-2x^3+9x^3)+(x^2-6x^2+12x^2)+(3x-8x)+4=3x^4+7x^3+7x^2-5x+4.[/tex]

Answer:

P =  8.5 x + 3  ft

Step-by-step explanation:

To find the perimeter, we use the formula

P =2(l+w) where l is the length and w is the width

P =2 (1.25x+3 + 3x-1.5)

Combine like terms

P = 2( 4.25x +1.5)

Distribute the 2

P =  8.5 x + 3  ft

The perimeter of the rectangle in terms of x is [tex]\( {\frac{17}{2}x + 3} \)[/tex].

Given the width of the rectangle is (3x - 1.5) feet and the length is  (1.25x + 3) feet, we can substitute these expressions into the perimeter formula.

First, let's express the width and length in terms of xwith rational numbers to avoid dealing with decimals:

 Width [tex]\( w = 3x - \frac{3}{2} \)[/tex]

Length [tex]\( l = \frac{5}{4}x + 3 \)[/tex]

Now, we can calculate the perimeter:

[tex]\( P = 2(l + w) \)\\ \( P = 2 \left( \left( \frac{5}{4}x + 3 \right) + (3x - \frac{3}{2}) \right) \)\\ \( P = 2 \left( \frac{5}{4}x + 3 + 3x - \frac{3}{2} \right) \)\\ \( P = 2 \left( \frac{5}{4}x + 3x + 3 - \frac{3}{2} \right) \)\\ \( P = 2 \left( \frac{5}{4}x + \frac{12}{4}x + \frac{6}{2} - \frac{3}{2} \right) \)\\ \( P = 2 \left( \frac{17}{4}x + \frac{3}{2} \right) \)\\ \( P = 2 \times \frac{17}{4}x + 2 \times \frac{3}{2} \)\\ \( P = \frac{34}{4}x + 3 \)\\ \( P = \frac{17}{2}x + 3 \)[/tex]

perimeter =  [tex]\( {\frac{17}{2}x + 3} \)[/tex].

Step-by-step explanation:

The exact volume email of the cylinder in the image is 324π in³.

This is calculated using the formula for the volume of a cylinder:

Volume = πr²h

where:

π is a mathematical constant with the approximate value of 3.14

r is the radius of the cylinder

h is the height of the cylinder

In the image, the radius of the cylinder is 3 in and the height is 6 in. Therefore, the volume of the cylinder is:

Volume = π(3 in)²(6 in)

Volume = π(9 in²)(6 in)

Volume = 54π in³

However, the image also contains the text 324π in³.

This is the correct volume of the cylinder, as it takes into account the fact that the cylinder is hollow.

Therefore, the exact volume email of the cylinder in the image is 324π in³.

Given is - the monthly maintenance costs have an average of $3500 and a standard deviation of $257. This means that around 95% of the distributed data lies within the ranges of -257 to +257 of the given standard deviation.

Hence, range becomes :

[tex]3500-257=3243[/tex] and [tex]3500+257=3757[/tex]

Thus, the range is (3243 , 3757)

Answer:

If X denotes the monthly maintenance costs of the company then

X is N(3500,257)

To find out 95% of the range we have Z critical = 1.96

So lower bound of range[tex]= 3500-1.96*257[/tex] and

m - slope

b - y-intercept

We have the slope m = -4 and the point M(-2, 1).

The equation of a line:

[tex]y=-4x+b[/tex]

Put the coordinates of the point M to the equation of a line:

[tex]1=-4(-2)+b[/tex]

[tex]1=8+b[/tex]      subtract 8 from both sides

The inequality -6n < -12 has all numbers greater than 2 as its solution after isolating 'n'. We achieve this by dividing both sides by -6 and flipping the inequality sign.

To solve this inequality, -6n < -12, you first need to isolate 'n' on one side of the inequality. We do this by dividing both sides of the inequality by -6. It's important to remember that when we divide or multiply an inequality by a negative number, we need to flip the direction of the inequality sign. So, the inequality would become n > 2. This means that all numbers greater than 2 are the solutions of the inequality.
