A retailer sends scratch-off coupons to registered customers; 30% of the coupons will reveal a discount of 50%.
Before mailing, a manager selects 10 coupons at random from the stack of printed coupons and scratches to
reveal the discount.
What is the probability that at least one of the coupons will reveal a discount of 50%?
Answer:
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.

If 'a' is an odd number, which of the following is also odd?
3a + 1
о
a + 2
O +
2a + 2
a + 1
=================================================
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.

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.

find the value of x. Round to the nearest degree
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

Is the given value a solution of the inequality?
z + 2 > - 4; z = -8
Answer:
z = -8 is not a solution to the given inequality.
Step-by-step explanation:
Step 1: write the inequality
z + 2 > -4
Step 2: substitute z with the given value
-8 + 2 > -4
Step 3: evaluate the left side
-6 > -4
Step 4: is the last inequality above true or false?
Since -6 is less than -4, -6 > -4 is false.
Answer: z = -8 is not a solution to the given inequality.

La senora carmen pidio un prestamo en cierta financiera de $3,000 con un interes mensual del 8% y quiere saber cuanto debe pagar en total al termino de 3 meses
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
Find the inequality represented by the graph
Answer:
y<or equal to 5/2x + 5
Step-by-step explanation:
when graphing inequalities, the line is solid when the inequality is also "or equal to". also, the less than sign indicates that the area below the line will be shaded. the y intercept is the y value when x is 0, so + 5. the slope, calculated with rise over run, is 5/2x

I have a question that says " jada has read 3/5 of a book. She has read 75 pages so far. How many pages are in the whole book?" (I NEED HELP)
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.
