Answer:

3. 9n + 6 = 78

5. see below

Step-by-step explanation:

3.

Let the number of adults be n. Each adult ticket costs $9, so the cost of n adult tickets is 9n. There is only one child, and a child's ticket is $6, so the cost of the child's ticket is 6. Adding the costs, you get 9n + 6. The total cost is $78, but the expression representing the total cost is 9n + 6, so 9n + 6 must equal 78. That is the equation.

9n + 6 = 78

Answer:

Step-by-step explanation:

a) Standard deviation of 10 mean the fluctuation for values range from +10 to -10 from the mean.

b) Since the sixth student is 50 minutes, which is higher than the mean of 45 minutes, this will bring the over all mean higher that 45 minutes.  Also, since 50  falls within the standard deviation range (35  to 55), this mean the new standard deviation will be smaller than 10.
