There are 12 applicants for financial aid. The Scholarship allows four students to receive the money. How many different ways can these scholarships be awarded? The first scholarship is $1000, the second is $750, the third is $500, and the last is $250. Only place a numeric value as an answer.

Answers

Answer:

495 ways

Step-by-step explanation:

Given that:

Total number of applicants (n) = 12

Required number (r) = 4

Using the combination formula :

nCr = n! / (n-r)!r!

12C4 = 12! / (12 - 4)!4!

12C4 = 12! / 8!4!

12C4 = (12*11*10*9) / 4*3*2*1

12C4 = 11880 / 24

= 495 ways

gil borrows $8000 for college expenses. he will pay a total of $2280 back in interest after 6 years. what was his interest rate

Answers

Answer:

R = 41.8129%/year

Equation:

r = (1/t)(A/P - 1)

Calculation:

Solving our equation:

r = (1/6)((8000/2280) - 1) = 0.41812865

r = 0.41812865

Converting r decimal to R a percentage

R = 0.41812865 * 100 = 41.8129%/year

The interest rate required to get a total amount, principal plus interest, of $8,000.00 from simple interest on a principal of $2,280.00 over 6 years is 41.8129% per year.

Step-by-step explanation:

Answer:

I believe it is 4.75 %

Step-by-step explanation:

2,280 × 100 = 228,000

228,000 / 8,000 = 28.5

28.5/6 = 4.75 %

find the number of words with or without meaning , which can be made by using all the letters of word ganga

Answers

Answer:

There are total 5 letters , of which A occur two times and G occur 2 times

Therefore , The number of permutations starting with A is 4! i.e 24

Thus , 25th word will be start from G i.e GGAAN

By rearranging according to the dictionary , we get

The 26th word will be GGANA

Hence , the 26th word is GGANA

Answer:

30

Step-by-step explanation

total number of letters in the word, n = 5

out of which G and A repeats 2 times each

p1 = p2 = 2

according to the equation of number of permutations,

= [tex]\frac{n!}{p_{1}! p_{2}! }[/tex]

total number of words = 5!/ (2! x 2!)

                                      = 30


The difference of the squares of two positive consecutive even integers is 84. Find the integers.

Answers

Answer:

The two integers are 20 and 22.

Step-by-step explanation:

Let x be the first integer.

[tex](x+2)^{2}-x^{2} = 84\\x^{2} +4x+4-x^{2} = 84\\4x = 80\\x = 20[/tex]

Applying the difference of squares, and solving the equation, it is found that the numbers are 20 and 22.

----------------------

The two consecutive even integers are: n and n + 2.The difference of the squares is given by:

[tex]D_s = (n+2)^2 - n^2[/tex]

Expanding the difference:

[tex]D_s = n^2 + 4n + 4 - n^2[/tex]

[tex]D_s = 4n + 4[/tex]

----------------------

The difference is 84, thus:

[tex]D_s = 84[/tex]

Now, we solve for n.

[tex]4n + 4 = 84[/tex]

[tex]4n = 80[/tex]

[tex]n = \frac{80}{4}[/tex]

[tex]n = 20[/tex]

----------------------

Thus, the numbers are: [tex]n = 20[/tex] and [tex]n + 2 = 20 + 2 = 22[/tex]

4x^2-21x-18=0
Find the discriminate

Answers

a = 4, b = -21, c = -18

to keep from getting "mixed up", evaluate the discriminant first ...

b<sup>2</sup> - 4ac = (-21)<sup>2</sup> - 4(4)(-18) = 729

sqrt(729) = 27

x = (21 +/- 27)/8

x = -3/4, x = 6

since the discriminant is a perfect square, the original quadratic will factor ...

4x<sup>2</sup> - 21x - 18 = 0

(4x + 3)(x - 6) = 0

x = -3/4, x = 6

Answer:729

Step-by-step explanation: Use the values of a, b and c to find the discriminant. Which is 729

What is the correct factorization of:
x? - 11x + 18

Answers

9514 1404 393

Answer:

  x² -11x +18 = (x -9)(x -2)

Step-by-step explanation:

The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.

  18 = (-1)(-18) = (-2)(-9) = (-3)(-6)

The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...

  x² -11x +18 = (x -9)(x -2)
