Step-by-step explanation:
The probability of having a boy is 50%
To calculate the probability of him having 2 boys, multiply the probabilities together
0.5(0.5) = 0.25
Answer:
Option D is correct.
Step-by-step explanation
Principal = $9250
rate of interest = 7% or 0.07
time = 5 years or 260 weeks
[ Since there are 52 weeks in a year . for 5 years it will be 5x52=260 weeks]
Applying the formula
Amount after t years = 
where P = principal
r = rate % in decimals
n= number of times in a year
t = times ( in years)
plugging the values in the formula
Amount = 
= 
= 
= 9250(1.418733588)
=$13123.29

Answer:
The boats are far apart by 4506.1 feet
Step-by-step explanation:
from the graph attached
i) BC = 1353
= 2761.82 feet
ii) BD = 1353
= 1744.28 feet
iii) the boats are far apart by = CD = CB + BD = 2761.82 + 1744.28 = 4506.1 feet
