Answer:

80/121

Step-by-step explanation:

For simplicity,

Probabilities of getting a red, a blue or a green in a single spin are, respectively, 4/11, 4/11 & 3/11.

Therefore, probabilities of getting 2 reds, 2 blues or 2 greens in 2 spins are, 16/121, 16/121 & 9/121 respectively.

Then, total probability of getting same colour both times would be 16/121 + 16/121 + 9/121 = 41/121.

Any other option would result in 2 different colours. Thus, the probability of getting two different colours in 2 spins = 1 - 41/121 = 80/121.

Fiona bought some socks that cost $4.95 for each pair and some belts that cost $6.55 each. Fiona spent $27.95 in all. Let a repr
Romashka [77]
The question lacks the total number of socks and belts altogether. Thsi value is necessary so that we can create another equation to solve the unknowns.

if assumed that a = b, the answer, a = b = 2.43 will not make sense since you cannot buy 43% of a pair of socks. Completely define the conditions so that the answer can be obtained. 

by trial and error, 3 pair of socks and 2 belts would be a sensible answer

. A condo in Orange Beach, Alabama, listed for $1.4 million with 20% down and financing at 5% for 30 years. What is the monthly
vovikov84 [41]
Listed price = $1.4 million
Down payment = 20% of $1.4 million = 0.2 x 1,400,000 = 280,000
Amount left to pay = $1.4 million - 280,000 = $1,120,000
Present value of an annuity is given by PV = P(1 - (1 + r/t)^-nt) / r
where: PV = $1,120,000
r = 5% = 0.05
t = 12
n = 30 years.
1,120,000 = P(1 - (1 + 0.05/12)^-(12 x 30)) / 0.05
1,120,000 x 0.05 = P(1 - (1 + 1/240)^-360)
56,000 = P(1 - 0.2238)
P = 56,000 / 0.7761 = 72,148.83
Therefore, the monthly payment is $72,148.83

Find m A. 10 B. 5 C.√53 D. 10√3/3
MArishka [77]

Answer:

m = 10

Step-by-step explanation:

Looking at the angles, we can see that this is a 30-60-90 triangle.

The side that is with the 30° angle and the 90° angle is represented by x\sqrt{3}.

So let's find x.

x\sqrt{3} = 5\sqrt{3}

Divide both sides by \sqrt{3}:

x = 5.

Now the hypotenuse is always 2x (the leg with the 90° and 60° is just x.) So,

2x = 2\cdot5 = 10.

Hope this helped!

  • Given, Someone started fishing at 3:30 am after fishing for 2hours 15min. he rested for half an hour(30min).
  • Thus,  Now The Clock is Rotating to 3:30 am + 2hour 15 min. + 30 min. = 6:15 am .

He then continued doing Fishing until 11 am. As a result, he fished for 4 h 45 min. more after resting.

So the Total Time he Spends Fishing is 4 hour 45 min. + 2 hours 15 min.
