Answer:
1/50
Step-by-step explanation:
Given that:
- Three men: 3
- Seven women = 7
- Total number of people: 7+3 =10
We need to find the probability that no man will be interviewed until at least two women have been interviewed. So there are two possible probabilities are:
1. One man and two women => P(1 man and 2 women) = 3/10*2/9 = 1/15
2. Three women => P(3 women) = 3/10
Hence, the probability in this situation is: 1/15*3/10 = 1/50
Answer:
A. 5.16 s.
B. 5.66 s.
Step-by-step explanation:
A.
For a simple harmonic motion,
T = 2pi (sqrt * (l/g))
Given:
L1 = 3 cm
T1 = 4 s
L2 = 5 cm
T2 = ?
4 = 2pi*sqrt(3/g)
g = 7.4
At, L2,
T2 = 2pi*sqrt(5/7.4)
= 5.16 s.
B.
M1 = M1
M2 = 2*M1
For a simple harmonic motion,
T = 2pi (sqrt * (m/k))
4 = 2pi (sqrt * (M1/k))
M1/k = 0.405
Inputting the above values,
T2 = 2pi (sqrt * (2*M1/k))
= 2pi (sqrt * (2 * 0.405))
= 5.66 s.
46.5cm squared I believe
Hope this helped ;)

To calculate a fraction of a quantity, multiply the quantity by the numerator of the fraction and divide by the denominator
of 20 = (3 × 20 )/4 =
= 15
of 20 = (3 × 20 )/5 =
= 12
Answer: 6
Step-by-step explanation: you multiply x4 and -3 because the parenthesis and then you add.
