35/40
That is one of them.
Answer: 
Step-by-step explanation:
n(gold colored coins) = 10
n(silver colored coins) = 6
Total number of coins = 16
since there is replacement , the probability she selects 2 silver colored coins will be :
x
= 
x
=
Therefore : the probability she selects 2 silver colored coins is
The population will be about 2972 population in 2020
<h3>Exponential functions </h3>
The standard exponential equation is expressed as;
y = ab^x
where
- a is the intercept
- b is the initial population
- x is the time
Given the following parameters
Substittute the given parameters into the formula
y = 2000(1.02)^x
If x = 20 (from 2000 to 2020)
The population will be expressed as;
y = 2000(1.02)^20
y = 2972 populations
Hence the population will be about 2972 population in 2020

Answer:
Step-by-step explanation:
a)
p(d) - probability of a rivet being defective
p(r) - probability of seam needing to be reworked
The probability of the seem needing to be reworked is equal to the probability that ANY of 24 rivets is defective
Thus the probability that none of the 25 rivets is defective is 1-p(r)
p(r) = 16%, thus 1-p(r) = 84%
1-p(r) = (1-p(d))^24
0.84 = (1-p(d))^24
0.84^(1/24) = 1-p(d)
==> 1-p(d) = 0.9927615998
==> p(d) = 1-0.9927
==> p(d) = 0.0073
b) given p(r) = 8%, thus 1-p(r) = 92%
1-p(r) = (1-p(d))^24
0.92 = (1-p(d))^24
0.92^(1/24) = 1-p(d)
==> 1-p(d) = 0.99653179446
==> p(d) = 1-0.9965
==> p(d) = 0.0035
V = (edge)^3
If you know the volume, take the CUBE ROOT on both sides to find the edge.
