=(4/7)^3
=(4/7)*(4/7)*(4/7)
=4*4*4 / 7*7*7
=4^3 / 7^3
=64/343
Answer is D.
Answer: it is d becaues that is the mode
X= # of adults
y= # of children
1326= 6x + 4y
289= x + y
We are going to do substitution.
x = 289-y
1326= 6(289-y) + 4y
1326= 1734 -6y + 4y
1326= 1734 + -2y
-408= -2y
204 = y
Since we now have a value for y, we should plug that back into the equation we got the x value from to find the actual numerical value of x.
289= x + y
289= x + 204
85= x
In conclusion, 85 adults and 204 adults went to the swimming pool.
Tiffany: x/3 books
Brother: (4/9)x - 15 books
Sister: x/3 - x/9
Total: x/3 + (4/9)x - 15 + x/3 - x/9
The LCD here is 9. Mult. all terms by 9 and simplify the resulting expression:
3x + 4x - 135 + 3x - x = 7x + 3x - x - 135 = 9x - 135 books (answer)
Answer:
The answer is 40 320 ways.
Step-by-step explanation:
In permutation, object cannot be reuse and order matters.
So for this question, MULTIPLY can be arranged in many forms :
8P8 = 40 320
