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.
X^2+5+6 What is the solution
Answer:
X^2+11
add the 5 and 6
you can't add the x^2 to anything

The table shows the estimated distances and elevation changes between a base camp and various
locations along a popular mountain trail. The distance traveled along the trail is represented by x, the
elevation is represented by y, and the time from the base camp to each location is represented by t.
1. Use the data points about the distance and elevations of the camps to graph the data points where the
x-coordinate is the total distance traveled from the base camp and the y-coordinate is the elevation. Use
the grid below or include a screenshot of the data plotted from a calculator. (5 points)

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.
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.

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

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.

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

In ΔTUV, the measure of ∠V=90°, the measure of ∠T=42°, and UV = 20 feet. Find the length of TU to the nearest tenth of a foot.
Answer:
29.9 feet
Step-by-step explanation:
sin 42= 20/x
X sin 42=20 cross multiply
X sin 42/sin 42 = 20/sin 42 Divide each side by sin 42
X = 20/sin 42 = 29.8895 ~ 29.9 feet
