Answer: 162 in²
Step-by-step explanation:
The factors of 54 are listed below:
18 and 9 are the two factors that when plugged into the equation below, equals 54:
This can also be written as:
So now that we have our two factors, we need to multiply them by each other to get our answer.
18 times 9 = 162
Our answer is 162
It would be a parabola, or quadratic, but prolly parabola
6/9 just multiply both parts of the fraction by 3
Answer:
B. no, it is not low enough
A. no, it is not low enough
Step-by-step explanation:
Given that Air-USA has a policy of booking as many as 24 persons on an airplane that can seat only 22.
Prob for a random person booked arrive for flight = 0.86
No of persons who books and arrive for flight, X is binomial, since there are two outcomes and each person is independent of the other
The probability that if Air-USA books 24 persons, not enough seats will be available
= P(X=23)+P(x=24)
= 0.1315
B. no, it is not low enough
-------------------------------
The prob we got is >10% also
A. no, it is not low enough
Answer:
A
Step-by-step explanation:
This explanation mostly depends on what you're learning right now. The first way would be to convert this matrix to a system of equations like this.
g + t + k = 90
g + 2t - k = 55
-g - t + 3k = 30
Then you solve using normal methods of substitution or elimination. It seems to me that elimination is the quickest method.
g + t + k = 90
-g - t + 3k = 30
____________
0 + 0 + 4k = 120
4k = 120
k = 30
No you can plug this into the first two equations
g + t + (30) = 90
g + t = 60
and
g + 2t - (30) = 55
g + 2t = 85
now use elimination again by multiplying the first equation by -1
g + 2t = 85
-g - t = -60
_________
0 + t = 25
t = 25
Now plug those both back into one of the equations. I'll just do the first one.
g + (25) + (30) = 90
g = 35
Therefore, we know that Ted spent the least amount of time on the computer.
The second method is using matrix reduction and getting the matrix in the row echelon form, therefore solving using the gauss jordan method. If you would like me to go through this instead, please leave a comment.
