There are 360 ways for a four-letter words that can be formed using the letters of the word finite. So, correct option is B.

To find the number of four-letter words that can be formed using the letters of the word "finite," we can use the permutation formula, which is:

nPr = n! / (n-r)!

where n is the total number of items to choose from, and r is the number of items to choose. In this case, we have 6 letters to choose from (n=6), and we want to choose 4 letters (r=4).

Therefore, the number of four-letter words that can be formed is:

6P₄ = 6! / (6-4)!

= 6! / 2!

= (6 x 5 x 4 x 3 x 2 x 1) / (2 x 1)

= 720 / 2

= 360

Therefore, the answer is 360, which corresponds to option B.

In summary, there are 360 four-letter words that can be formed using the letters of the word "finite," by using the permutation formula to calculate the number of possible arrangements of the 6 letters taken 4 at a time.

So, correct option is B.

Answer:

9

Step-by-step explanation:

After driving for 5 hours, Arun's car would have used up 5 gallons of gas (1 gallon per hour for 5 hours). Therefore, the amount of gas left in the tank after driving for 5 hours would be 9 gallons - 5 gallons = 4 gallons.

To find the amount of gas left after t hours, we can use the formula:

Gas left after t hours = 9 - (1 x t)

Where t is the number of hours driven.

So, the amount of gas left after t hours would be 9 - t gallons.

After driving for 5 hours, Arun would have 4 gallons of gas left in his tank. If he drives for t hours, he would have (9 - t) gallons of gas left in his tank. The calculations are based on the fact that Arun's car uses 1 gallon of gas per hour of driving.

To answer this question, we must understand that Arun's car uses 1 gallon of gas for every hour of driving. So, if he drives for 5 hours, his car will use 5 gallons of gas. Arun starts with 9 gallons of gas, so we subtract the 5 gallons of gas used from the 9 gallons of gas he started with. The result is:

9 - 5 = 4 gallons

So, after driving for 5 hours, Arun would have 4 gallons of gas left in his tank.

Similarly, if he drives for t hours, his car will use t gallons of gas. So, to find how much gas would be left after driving for t hours, we subtract t gallons from the 9 gallons he started with:

9 - t = (9 - t) gallons

Thus, after driving for t hours, Arun would have (9 - t) gallons of gas left in his tank.

If an independent-measures design is used, a total of 20 participants would be needed, with 10 participants in each treatment condition.

If a repeated-measures design is used, only 10 participants would be needed since each participant would serve as their own control and be tested in both treatment conditions.  If a matched-subjects design is used, the number of participants needed would depend on how many pairs of matched subjects are needed.

Answer:

(x + 6)(x + 7)

Step-by-step explanation:

To factor the trinomial x^2 + 13x + 42, we need to find two numbers that multiply to 42 and add up to 13.

One way to do this is to list all the pairs of factors of 42 and see which pair adds up to 13:

1, 42 -> 1 + 42 = 43

2, 21 -> 2 + 21 = 23

3, 14 -> 3 + 14 = 17

6, 7 -> 6 + 7 = 13

So the pair of factors that we want is 6 and 7. We can use these numbers to rewrite the middle term of the trinomial:

x^2 + 13x + 42 = x^2 + 6x + 7x + 42

Next, we can group the first two terms and the last two terms:

x^2 + 6x + 7x + 42 = (x^2 + 6x) + (7x + 42)

Now, we can factor out the greatest common factor from each group:

x(x + 6) + 7(x + 6)

Notice that we have a common factor of (x + 6) in both terms. We can factor this out:

(x + 6)(x + 7)

Answer:

ZX = 1.3 in

EG = 3.0 in

M∠X = 48°

M∠G = 25°

Step-by-step explanation:

As we can see in the attached figure that these two triangles are identical i.e their corresponding sides and angles are equal

Therefore if we say that

ZX = EF

So ZX = 1.3 in.  

Now the same is applied for other sides and angles

EG = XY

So, EG = 3.0 in

M∠X = M∠E

hence, M∠X = 48°

For the M∠ G,

The angle is

= 180° - 107° - 48°

= 25°

Hence, the M∠ G is 25°

Answer:

The recursive formula of the geometric sequence is:

Step-by-step explanation:

A recursive formula is a formula using which every next term is based on the previous term.

Each next term of a geometric sequence can be determined when we multiply the previous term with a constant. That constant number is called a 'common ratio' which is denoted by 'r'.

Given the sequence

27, -9, 3, -1,...

Let us find the common ratio 'r' of all the adjacent terms

r = -9/27 = -1/3,   r = 3/-9 = -1/3, r = -1/3

Thus, the common ratio is: r= -1/3

The recursive formula for the geometric sequence is:

aₙ = aₙ₋₁ (r)

Here,

aₙ represents the general term

aₙ₋₁ represents the previous term

'r' represents the common ratio

as

a₁ = 27

Substituting our values, we have

aₙ=aₙ₋₁(r)

Putting n=2 to get the second value

a₂=a₂₋₁(-1/3)

   = a₁ (-1/3)

   = 27 (-1/3)

   = -9

Thus, the next term of a geometric sequence can be determined when we multiply the previous term with a constant.

Therefore, the recursive formula of the geometric sequence is:

Answer:

63+38=101

Step-by-step explanation:

The y as a function of t if 576y′′ + 336y′ + 49y = 0; y(0) = 6, y′(0) = 3 is y = 6\(e^{-7/24x}\) + 4.75x\(e^{-7/24x}\).

The function is:

576y′′ + 336y′ + 49y = 0

The values are y(0) = 6, y′(0) = 3.

The coefficients of this linear differential equation are constant. So, we'll hazard a guess at the following solution:

y = \(e^{rx}\), r being the parameter.

We will calculate and add to the equation:

y' = r\(e^{rx}\)

Again integrate the function

y'' = r²\(e^{rx}\)

Substitute the value of y' and y'' in the function

576r²\(e^{rx}\) + 336r\(e^{rx}\) + 49\(e^{rx}\) = 0

(576r² + 336r + 49)\(e^{rx}\) = 0

576r² + 336r + 49=0

This equation is square. It only has one remedy: r = ±7/24

The general answer will therefore be:

y = A\(e^{-7/24x}\) + Bx\(e^{-7/24x}\)

To find A and B we'll first need to derive y:

y' = (-7/24)A\(e^{-7/24x}\) + B\(e^{-7/24x}\) - (7/24)Bx\(e^{-7/24x}\)

Introducing the initial conditions now:

y(0) = 6

y(0) = Ae⁰ + B × 0 × e⁰

6 = A × 1 + 0

A = 6

y'(0) = 3

y'(0) = (-7/24) × 6 × e⁰ + Be⁰ - (7/24) × B × 0 × e⁰

3 = (-7/24) × 6 × 1 + B × 1 - (7/24) × B × 0 × 1

3 = (-7/4) + B - 0

Add by 7/4 in both side, we get

B = 19/4

B = 4.75

And the general solution is:

y = 6\(e^{-7/24x}\) + 4.75x\(e^{-7/24x}\)

(a) Basis for the column space: {[2, 7, -2, 2], [-3, -6, 1, -2]}

(b) Rank of the matrix: 2

To find a basis for the column space and the rank of the matrix, we need to perform row operations on the matrix and find the pivot columns. The pivot columns will form a basis for the column space, and the number of pivot columns will give us the rank of the matrix.

Let's perform row operations on the given matrix to reduce it to row-echelon form:

[2  4  -3  -6]

[7  14 -6  -3]

[-2 -4  1   -2]

[2  4  -2  -2]

R2 = R2 - 3*R1

R3 = R3 + R1

R4 = R4 - R1

This gives us:

[2  4  -3  -6]

[1  2  3   3 ]

[0  0  -2  -8]

[0  0  1   4 ]

R3 = (-1/2) * R3

R4 = R4 - (1/2) * R3

[2  4  -3  -6]

[1  2  3   3 ]

[0  0  1   4 ]

[0  0  0   0 ]

Now, we can see that the columns with pivots (leading 1's) are the first and third columns. Therefore, a basis for the column space consists of these two columns:

Basis for column space: [2, 7, -2, 2] and [-3, -6, 1, -2]

The rank of the matrix is the number of pivot columns, which is 2.

Therefore,

(a) a basis for the column space: {[2, 7, -2, 2], [-3, -6, 1, -2]}

(b) the rank of the matrix: 2

Option D. The median cost of course materials for nursing majors is over $300 more than the median cost of course materials for non-nursing majors.

The given boxplots show the circulation of the expense obviously materials for nursing majors and non-nursing majors. From the plots, we can reason that the scope of the circulation of the expense obviously materials for nursing majors is like that of non-nursing majors, as the most extreme and least qualities are around at a similar level. We can likewise infer that the most extreme expense for non-nursing majors is more prominent than the middle expense for nursing majors.

Also, the inconstancy of the expense obviously materials for the center half of nursing majors is more noteworthy than the fluctuation of the center half for non-nursing majors, as the cases for nursing majors are more extensive. In any case, we can't reason that the middle expense obviously materials for nursing majors is more than $300 more than the middle expense obviously materials for non-nursing majors, as the medians are not straightforwardly named and their division isn't plainly shown.
