The arnold family arrived at the beach at 10:30 A.M.
10:30
Add 3 hours and 3/4 minutes to that
3/4 = 75% of 60
.75 * 60 = 45
3 hours and 45 minutes
10:30 >> 3 hours more = 1:30
1:30 + 45 mins = 2:15
Answer would be: They left at 2:15
Answer:
Last Choice / D
Step-by-step explanation:
you want to isolate v!
E = 1/2 m v^2
multiply both sides by 2
2E = mv^2
divide both sides by m
2E/m = v^2
square root both sides
v = ±

Answer:
the probability that a code word contains exactly one zero is 0.0064 (0.64%)
Step-by-step explanation:
Since each bit is independent from the others , then the random variable X= number of 0 s in the code word follows a binomial distribution, where
p(X)= n!/((n-x)!*x!*p^x*(1-p)^(n-x)
where
n= number of independent bits=5
x= number of 0 s
p= probability that a bit is 0 = 0.8
then for x=1
p(1) = n*p*(1-p)^(n-1) = 5*0.8*0.2^4 = 0.0064 (0.64%)
therefore the probability that a code word contains exactly one zero is 0.0064 (0.64%)
Answer:
y=0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2.6y-4/15y+7/6y=7/3y
2.6y-(-)4/15y+7/6y=7/3y
(2.6y-4/15y+7/6y)=7/3y (combine like terms)
7/2y = 7/3y
Step 2: Subtract 7/3y from both sides.
7/2y - 7/3y = 7/3y - 7/3y
7/6y = 0
Step 3: Multiply both sides by 6/7
6/7 . 7/6y = 6/7 . 0
y = 0
