Answer:
189 tickets sold on Saturday.
Step-by-step explanation:
Your ratio of 8:1 is children's tickets to adult tickets.
There are 8 times as many children tickets sold as adult tickets.
Let c = # children's tickets
Let a = # adult tickets
8a = a + 147
subtract a from both sides
7a = 147
divide on both sides by 7
a = 147/7
find number of adult tickets
a = 21 adult tickets
multiply the number of adult tickets by 8 to find children's tickets 21*8=168
168+21=189 tickets sold on Saturday.
Due to the u-shaped graph suggested by these data points, this would best be matched with a quadratic function.
Answer:
Option d.
Step-by-step explanation:
we know that
The graph of a continuous probability distribution is a curve. Probability is represented by area under the curve.
The curve is called the probability density function (abbreviated as pdf).
We use the symbol f(x) to represent the curve
therefore
The probability density function f(x) represents . the height of the function at x.
Answer:
Dependent: Cost of the ride.
Independent : Number of rides.
Step-by-step explanation:
The independent variable is the variable what we change and the dependent variable is the variables which changes because of that changes.
Here the total cost of ride changes for any change in the number of rides.
Hence, the number of rides is the independent variable and the total cost of ride is the dependent variable
