C) 0.972

Step-by-step explanation:

I am just as confused as you are but i tried understanding what "at least one" meant and my 2nd option was X>= 1, or something to that effect where 10 to 1 coupons being possible.

=================================================

Explanation:

Adding an even number to an odd number always results in an odd number

even + odd = odd

odd + even = odd

So if 'a' is odd, adding 2 onto it (even number), leads to an odd result of a+2.

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

Extra Information (optional section)

If you are curious why the two equations shown above are true, then here's a proof.

Let 'a' be an odd number. This means a = 2k+1 for some integer k. We add 1 to any multiple of 2 and it goes from even (2k) to odd (2k+1).

If we made b an even number, then b = 2m for some integer m.

Adding 'a' and b gives us...

c = a + b

c = ( a ) + ( b )

c = ( 2k+1 ) + ( 2m )

c = (2k+2m) + 1

c = 2(k+m) + 1

c = 2n + 1 .... where n = k+m

The result a+b is an odd number since it is in the form 2*(integer)+1

It verifies the claim that odd+even = odd.

So this shows that a+2 is also odd, since we let b = 2.

208 in

Step-by-step explanation:

[tex](8x8)+(\frac{1}{2} x8x9)x4in^{2} \\\\=64+36x4 in\\ \\=208 in^2[/tex]

have a great day!!

Answer:

[tex]208 in^2[/tex]

Step-by-step explanation:

Total surface area

(8×8)+(1/2×8×9)×4in²

= 64+36×4in²

=64+144in²

= 208 in²

Answer:

Total money left with Jamie = £13

Step-by-step explanation:

Jamie received pocket money = £26

He spent on sweets = 10% of total pocket money

Expense on magazines = 25% of the total money

Expense on games = 15% of the pocket money

Total expenditure on sweets, magazines and games = [tex]\frac{10}{100}+\frac{25}{100}+\frac{15}{100}[/tex]

= [tex]\frac{50}{100}[/tex] Or 50% of the pocket money he received

Therefore, money left with Jamie = 50% of total money he received as pocket money

= [tex]\frac{50}{100}\times 26[/tex]

= £13

Answer:

the binomial theorem is a theorem that specifies the complete expansion of a binomial raised to any positive integer power.

Answer and Step-by-step explanation:

To solve, we would multiply by the reciprocal of the portion Jada has read, and multiply that number to 75.

The reciprocal means the the value, but flipped, so [tex]\frac{3}{5}[/tex] will become [tex]\frac{5}{3}[/tex].

Now we do 75 times [tex]\frac{5}{3}[/tex]/

[tex]\frac{75 * 5}{3} \\\\\\\\\frac{375}{3} \\\\\\\\125[/tex]

So, there are 125 total pages in the book.

Answer:

51 degress

Step-by-step explanation:

sin x = 7/9

x = sin^-1 (7/9)

simply using a calculator.

Answer:

x = 51 degrees

Step-by-step explanation:

(to find x, use sine)

Sine = [tex]\frac{opposite}{hypothenuse}[/tex]

⇒ Sine x = [tex]\frac{7}{9}[/tex]

⇒ [tex]\frac{7}{9}[/tex] = 0.78

⇒ Sine x = 0.78

then calculate what Sine-1 of 0.78 is:

⇒ Sine-1 of 0.78 = 51.26

x = 51.26

Round to the nearest degree:

51.26 ⇒ 51 degrees

Answer:

[tex]x = 7[/tex]

Step-by-step explanation:

1) Use Division Distributive Property: (x/y)^a = x^a/y^a.

[tex] \frac{1}{ {27}^{x - 8} } = 27[/tex]

2) Multiply both sides by 27^x - 8.

[tex]1 = {27} \times 27^{1 + x - 8} [/tex]

3) Use the product rule: x^a x^b = x^a+b.

[tex]1 = {27}^{1 + x - 8} [/tex]

4) Simplify 1 + x - 8 to x - 7.

[tex]1 = {27}^{x - 7} [/tex]

5) Use Definition of Common Logarithm: b^a = x if and only if logb (x) = a.

[tex] log_{27}1 = x - 7 [/tex]

6) Use Change of Base Rule.

[tex] \frac{ log_1 }{ log{27} } = x - 7[/tex]

7) Use rule of 1: log 1 = 0.

[tex] \frac{0}{ log_{27}} = x - 7[/tex]

8) Simplify 0/log_27 to 0.

[tex]0 = x - 7[/tex]

9) Add 7 to both sides.

[tex]7 = x[/tex]

10) Switch sides.

[tex]x = 7[/tex]

Therefor, the answer is x = 7.

Answer:

5x

Step-by-step explanation:

Responder:

$ 3720

Explicación paso a paso:

Dado que:

Tasa mensual, r = 8%

Principal, P = $ 3000

Duración o período, t = 3 meses

La cantidad final, A, que pagará después de 3 meses:

Usando la fórmula de interés simple:

A = P (1 + rt)

A = 3000 (1 + 0,08 * 3)

A = 3000 (1 + 0,24)

A = 3000 (1,24)

A = $ 3720
