There are 9 different positions on a baseball team. if a team has 18 players how many different line-ups can the team make?

Answers

Answer 1

Final answer:

To find the number of different line-ups a team can make, we use permutations. Using the formula for permutations, we arrive at the answer of 437,760 different line-ups.

Explanation:

To find the number of different line-ups a team can make, we need to use the concept of permutations. Since there are 9 positions on a baseball team and 18 players, we can arrange the players in a line-up using the formula for permutations:

P(n, r) = n! / (n-r)!

Where n is the total number of players (18) and r is the number of positions (9). Substituting the values, we get:

P(18, 9) = 18! / (18-9)! = 18!/9! = 437,760.

Therefore, there are 437,760 different line-ups that the team can make.

Suppose someone opens the valve on a large water tank so that water drains out. Choose a starting volume of water in the tank (from 100 to 500 gallons), and choose how much water drains out each day (from 2 to 5 gallons). Write the equation that models the relationship between time (x) and water volume (y) in slope-intercept form.

Answers

If we are to choose any number from 100 to 500, you may take any other number but for the purpose of showing how things are done here, let me choose 100 gallons. Similarly, we choose 2 gallons to be drain out each day. 

The equation that would best represent the relationship between the given parameters is,
                               y = 100 - 2x

where y is the volume of water after x days.

The random variable X ≈ B(n, p)

Where n is the number of samples. If the value of n is huge, calculating binomial coefficient can be difficult and calculator won't be able to perform the nCr calculation for a big value of n (try ⁶⁰⁰C₁₂₃ on the calculator).

If p, which is the probability, is close to 0.5, the binomial distribution will be fairly symmetric.

We have n = 114 and p = 22% = 0.22

We first need to approximate X by Y ≈ N(np, np(p-1))

np = 114×0.22 = 25.08
np(1-p) = 114×0.22×0.78 = 19.6

Therefore, Y ≈ N(25.08, 19.6)
and since the standard deviation, б = √np(1-p) = √19.6
We then have, Y≈N(25.08, (√19.6)²)

We aim to find the probability of X is exactly 27, mathematically written as P(X=27)

Applying the continuity correction we have P(26.5<Y<27.5) ⇒ This correction, in other words, is applying a range to X that will definitely include the value of X=27

The next step is standardising
We have the mean, μ=25.08 and σ=√19.6

P(26.5<Y<27.5) = P([tex] \frac{26.5-25.08}{ \sqrt{19.6} } [/tex]<Z<[tex] \frac{27.5-25.08}{ \sqrt{19.6} } [/tex])
P(26.5<Y<27.5) = P(0.32<Z<0.55)
P(26.5<Y<27.5) = P(Z<0.55) - [1 - P(Z<0.32)] ⇒ Read the values for these z-score on the z-table
P(26.5<Y<27.5) = 0.7088 - [1-0.6255]
P(26.5<Y<27.5) = 0.3343

What positive number is the same as its reciprocal?

Answers

1     It's the only positive number whose reciprocal is its equal                                               
                                                
Final answer:

The only positive number that is the same as its reciprocal is 1. This is achieved by setting up the equation x = 1/x and solving it.

Explanation:

In mathematics, a number and its reciprocal are the same when the number is 1. If you denote the mysterious number we are looking for as 'x', then its reciprocal would be 1/x. Since the number and its reciprocal are the same, we can set up the equation x = 1/x. Solving this equation, we cross multiply to get x^2 = 1. The positive solution to this equation is x = 1, which confirms that the only positive number that is the same as its reciprocal is 1.

Alex is making a rectangular garden and wants a fence around it. He wants the length of the garden to be 3 feet longer than the width. 150 feet of fence is all he can afford. What is the greatest possible width he can have for his garden?

Answers

Since it's rectangular, there is a length and width. Let the width be w, and the length is then w+3. The total length of the fence is the perimeter, so 150 = 2*w + 2*(w+3) = 4w+6. Solving for w, this becomes w=(150-6)/4 = 144/4 = 36 feet.

Forming a Perfect Square Trinomial Form the perfect square trinomial in the process of completing the square. What is the value of c? x2 + 3x + c = + c

Answers

Answer:

9/4 on edg

Step-by-step explanation:

Final answer:

To form a perfect square trinomial from x² + 3x + c, we find c by taking half of 3, squaring it, which gives us 9/4. Hence, the value of c is 9/4, making x² + 3x + 9/4 a perfect square trinomial.

Explanation:

To form a perfect square trinomial in the process of completing the square, you need to find the value of c that completes the square for the given quadratic expression x² + 3x + c. The process involves taking half of the coefficient of x, squaring it, and adding it as the constant term c.

Given that the coefficient of x is 3, we take half of it, which is 3/2, and then square this value to get (3/2)² = 9/4. Therefore, the value of c that makes x² + 3x + c a perfect square trinomial is 9/4.

This method is very helpful in solving quadratic equations by completing the square, and it forms a basis for the derivation of the quadratic formula.

A house is advertised as having 1 420 square feet under roof. what is the area of this house in square meters? (a) 115 m 2

Answers

Final answer:

To convert square feet to square meters, we multiply the number of square feet (1,420) by the conversion factor (0.092903), resulting in approximately 132 square meters as the area of the house.

Explanation:

To convert the area of a house from square feet to square meters, we use the conversion factor where 1 square foot equals 0.092903 square meters. The house in question has 1,420 square feet, so we multiply this number by the conversion factor to find the area in square meters.a

1,420 square feet  * 0.092903 square meters/square foot = 131.92186 square meters.

We can round the final result to the nearest whole number, which gives us approximately 132 square meters as the area of the house.

What is the discriminant of 3x2-10x=-2 ?

Answers

The discriminant of [tex]3x^2-10x=-2[/tex] is 76

To find the discriminant of [tex]3x^2-10x=-2[/tex], we have to recall the quadratic formula.

Further Explanation

The formula of the quadratic equation can be expressed as [tex]ax^2+bx+c=0[/tex] and discriminant also expressed as [tex]D=b^2-4ac[/tex]

Using the quadratic formula, the given question can be expressed as:

[tex]3x^2-10x+2=0[/tex]

Where a = 3, b = -10, and c = 2

If we substitute the values, then the discriminant would be:

Recall the discriminant is [tex]D=b^2-4ac[/tex]

Therefore, we have

[tex]D=(-10)^2-4(3)(2)[/tex]

[tex]D=100-24[/tex]

[tex]D=76[/tex]

Thus, the discriminant of [tex]3x^2-10x=-2[/tex] is 76.

Discriminant is very helpful in quadratic equation as it helps reveals the number of real solutions to a given quadratic equation. In other words, it helps you to solve quadratic equation.

What is ancestral language?

In the historical linguistics tree model, a protolanguage is a hypothetical ancestral language from which several documented languages are thought to have evolved, constituting a language family. In most cases, protolanguages are unattested or, at most, only partially attested.

The languages of Norway, Sweden, Denmark, and Iceland descend from Old Norse. Numerous Indian languages, including Bengali, Hindi, Marathi, and Urdu, have their roots in Sanskrit. Each of these ancestral languages had a single common progenitor further back in time.

The term "cognates" in linguistics refers to words with the same etymological background. These are words that have the same pronunciation, spelling, and meaning in two different languages. For instance, Spanish has many words that are similar to English words.

To solve this problem, let us first remember that the formula for rate is:

rate = f (n) = A (r)^(n-1)

Where,

A = the 1st term

r = fractional rate of evaporation

n = number of terms

Now let us calculate for the fraction rate of evaporation, r. Since it is stated that the evaporation is happening at a fixed rate, therefore we can use any two given f (n) values to find for r. In this case, let us use when n=1 and 2.

r = 27 / 54

r = 0.5
