Answer:
D) -4x+14
Step-by-step explanation:
We are given with the expression
3 - (4x - 5) + 6
Here we are going to open the bracket at first step
as we have a negative sign in front of bracket the signs of the terms inside brackets will be reversed
3-4x+5+6
now we bring the like terms together
3+5+6 - 4x
Here 3, 5, 6 all are constant and hence like
14-4x
or
3 - (4x - 5) + 6= -4x+14
Hence our answer is -4x+14

Answer:
The procedure results in a binomial distribution
Step-by-step explanation:
If all 120 couples used the YSORT method, it is fair to assume that the probability of a baby being a boy or a girl are constant through all trials (120 couples). Assuming 120 randomly selected couples, there is a fixed number of independent trials. Finally, since the babies can only be a boy or a girl, the binary condition is satisfied and thus, the distribution is binomial
Answer:
2 feets
Step-by-step explanation:
Given that :
Alli's Initial depth = 6 feets
Number of feets in which Alli rose = 4 feets
Alli's new position relative to the surface of the pool:
Difference of Alli's initial depth and feets risen :
6 feets - 4 feets = 2 feets
Hence, Alli is now 2 feets below the surface of the pool.
T = k/R where k is the constant of variation, T=time and R=speed.
Plug in the given values:-
12 = k/60
k = 12*60 = 720
So the equation of variation is T = 720/R
At 85 mph we have
T = 720 / 85 = 8.47 hours (answer)
