10 POINTS PLEASE HELP DUE SOON

Firstly, solve 38C15.

Then solve 42C12.

Compare your answers.

The goal here is to see if 38C15 = 42C12.

Here is the formula:

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

Go for it.

Answer:

  10. $16,000

  11. 4%

  12. 16.9%

Step-by-step explanation:

10. The amount of the loan plus interest is given by the formula ...

  I = Prt

  P = I/(rt) = $7840/(0.07×7) = $16,000

Richard initially deposited $16,000.

__

11. The total of principal plus interest is ...

  A = P(1 +rt)

Solving for r gives ...

  r = (A -P)/(Pt) = (528000 -240000)/(240000×30) = 0.04 = 4%

The percentage rate used was 4%.

__

12. The interest formula is ...

  I = Prt

Solving for r gives ...

  r = I/(Pt) = $845/($1000×5) . . . . . . 60 months = 5 years

  r = 0.169 = 16.9%

To earn $845 in interest, you would need a rate of 16.9%.

Answer:

The area decreases by 1155.52 square meters

Step-by-step explanation:

a = pi * r ^ 2

d = 2 * r

r = d / 2

r = 96/2

r = 48

a1 = 3.14 * 48 ^ 2

a1 = 7234.56 square meters.

r = 88/2

r = 44

a2 = 3.14 * 44 ^ 2

a2 = 6079.04 square meters.

now we calculate the difference

a1 - a2 = 7234.56 - 6079.04

= 1155.52 square meters

Answer:

A.) (1 - p)^n

B.) 1 - (1 - p)^n

C.) (1 - p)^n + np*(1-p)^(n-1)

D.) 1 - (1 - p)^n - np*(1-p)^(n-1)

Step-by-step explanation:

General form of a binomial probability :

P(x = x) = nCx * p^x * q^(n-x)

q = 1 - p ; n = number of trials ; x = number of successes ; p = probability of success

A.) probability of no successes ;

P(x = 0) = nC0 * p^0 * (1 - p)^(n-0)

P(x = 0) = 1 * 1 * (1 - p)^n

P(x = 0) = (1 - p)^n

Probability of atleast one success = 1 - P(no success)

P(x ≥ 1) = 1 - P(x = 0)

P(x = 0) = (1 - p)^n

P(x ≥ 1) = 1 - P(x = 0) = 1 - (1 - p)^n

Probability of at most one success

P(x ≤ 1) = p(x = 0) + p(x = 1)

P(x = 0) = (1 - p)^n

P(x = 1) = nC1 * p^1 * (1 - p)^(n-1)

P(x = 1) = n * p * (1 - p)^(n-1) = np*(1-p)^(n-1)

P(x ≤ 1) = (1 - p)^n + np*(1-p)^(n-1)

Probability of atleast two successes:

(1 - probability of at most 2 successes)

P(x ≥ 2) = 1 - P(x ≤ 1)

P(x ≥ 2) = 1 - (p(x = 0) + p(x = 1))

P(x ≥ 2) = 1 - p(x = 0) - p(x = 1))

P(x ≥ 2) = 1 - (1 - p)^n - np*(1-p)^(n-1)

Answer: 3. either/or

Step-by-step explanation:

Answer:

1. neither/nor

2. not only/but also

3. either/or

4. not only/but also

5. neither/nor

Step-by-step explanation:

1. Often when someone first moves somewhere, they are not familiar with the language. I think both/and also works, because she may have prepared for the move, but more likely it's neither/nor.

2. You have it correct.

3. They can only pick one, so "both/and" doesn't apply.

4. You have it correct.

5. Parents do not like when their kids argue :). Neither my mother nor my father likes it when I argue with my little sister.

Answer:

12

Step-by-step explanation:

a² + b² = c²

a² + 9² = 15²

a² + 81 = 225

a² = 225 - 81

a² = 144

[tex]\sqrt{a^2} =\sqrt{144}[/tex]

a = 12

Answer:

12.60 inches

Step-by-step explanation:

Divide 5.08 by 2 to get 2.54. This means that for every 1 inch, there is 2.54 centimeter. Using this rule, we divide 32 by 2.54 to get 12.598 inches, or 12.60 if we round to the nearest hundredth.

Answer:

this is 4(2x−3)=4(2x)−4(3)distributive property

Answer:

The Distributive Property

Step-by-step explanation:

The distributive property states that the product of an expression and a sum is equal to the sum of the products of the expression and each term in the sum. For example, a(b + c) = ab + ac. The division property of inequality states that two unequal values divided by a positive number retain the same relationship.

Answer:

107 degrees

Step-by-step explanation:

First, subract 180 from 135 to get the angle for DFE, which is 45 degrees.

Then, add 45 to 28, which equals to 73 degrees.

Finally, subtract 180 from 73 to get the angle for DEF, which is 107 degrees.
