Remember the order of operations. The first step in this problem will be to solve the exponent.
Take (2x)^3. Remember that since there are parentheses around 2x, that means you have to cube 2 and x.
(2x)^3 = 2^3 * x^3 = 8x^3
Now multiply that answer by 4 to finish simplifying.
8x^3 * 4 = 32 x^3
Your answer should be: 32x^3
Answer: 12,800 Miles
Work: take the mph (1600) and multiply it by the time(8 hours) to get your distance traveled (12,800 miles)
8x+5= 69
Move +5 to the other. Sign changes from +5 to -5.
8x+5-5= 69-5
8x= 64
Divide by 8
8x/8= 64/8
x= 8
Answer : x= 8
Answer:
n is the fixed number of trials. x is the specified number of sucesses. N - X is the number of failures. P is the probablity of success on any given trail. 1 - P is the probabilty of failure on any given trial.
These probabilities hold for any value of X between 0 (lowest number of possible successes in n trials) and n (highest number of possible successes).
