Answer:
3:1
Step-by-step explanation:
240 necklaces in one month
180-sold on website
60- sold in shop
180:60
then you would simplify
so the final answer is 3:1
To calculate this probability we must take into account that there is the same probability that any of the 3 urns is chosen.
This probability is:
P (U1) = P (U2) = P (U3) = 1/3
Urn 1 contains 7 black and 3 red marbles
Urn 2 contains 2 black and 8 marbles network
Urn 3 contains 5 black marbles and 5 red marbles.
The probability of obtaining a black marble in Urn 1 is 7/10.
The probability of obtaining a black marble in Urn 2 is 2/10
The probability of obtaining a black marble in Urn 3 is 5/10.
Then we look for the probability of obtaining a black marble from urn 1 or a black marble from urn 2 or a black marble from urn 3. This is:
P (U1yB) + P (U2yB) + P (U3yB)
So:
(1/3) * (7/10) + (1/3) * (2/10) + (1/3) * (5/10) = 0,2333 + 0,0667 + 0,1667 = 0, 4667.
The probability that it is a black marble is 46.67%
Answer:
33.22 square inches
Step-by-step explanation:
Diameter to Radius:
Area of Circle:
We are given the diameter of a pancake as 4.6 inches, so the radius is 2.3 inches. Next, we have to apply the area of circle formula with pi as 3.14 and the radius as 2.3
Next, since there's two pancakes, we double 16.6106.
Lastly, we round to the nearest hundredth.
- 33.2212 ≈ 33.22 square inches
Therefore, the answer is 33.22 square inches.

Step-by-step explanation:
Answer:
(49π)/8 = 6.125π square inches
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr² . . . . . where r is the radius
A "14-inch" pizza has a diameter of 14 inches, so a radius of 7 inches. Then the area of the whole pizza is ...
A = π(7 in)² = 49π in²
The area of one of 8 equal slices will be 1/8 of that, or ...
slice area = (49π in²)/8 = 6.125π in²
The area of one slice of pizza is (49/8)π = 6.125π square inches.
