45,120 if its ten.
45,000 if its ten thousand
For P(t) = 920*1.06^(2t), the current population is 920, the percentage growth rate is 6% semiannually, and the population in 4 years will be 920*1.06^8 = 1466.
Selection B is appropriate.
_____
The 2 in the exponent means the growth factor 1.06 is applied twice for each increment of t, that is, twice in 1 year (semiannually).
Answer: Probability of scoring 2 hits = 0.63.
Step-by-step explanation:
Since we have given that
Number of dart throws at a target = 3
Probability of scoring a hit on any one throw = 30%
We will use "Binomial Distribution" i.e.
where,
n denotes number of dart throws at a target,
r denotes number of required throws
p denotes probability of success
(1-p) denotes probability of failure
So, Probability of success is given by
Probability of failure is given by
We will use "Binomial Distribution" i.e.
Hence, Probability of scoring 2 hits = 0.63.
Q must be positive in F.
F. r squared will be positive, because any number times itself is positive, and to get a positive number for the answer, the two numbers you multiply need to be the same sign. If r squared is positive, q must be too.
G. q does not have to be positive. If r is a negative number, then q can be negative. Say q=-2 and r=-3. -2-(-3) changes to -2+3, which equals 1.
H. Again, q can be negative if r is negative (two negative numbers multiplied together equals a positive answer.
J. q can be negative because even a negative number turns positive when squared.
Hope this helped you. :)
