Step-by-step explanation:
-2 x 14 = -28
b is the answer
$2, because if you do 8*25 you get 200 and if you divide that by 100 you get a total of 2 making the tax on the purchase $2.
Answer:
Quadratic, because the height increases and then decreases.
Step-by-step explanation:
In an exponential function, the graph will either increase or decrease over the entire domain. It does not change direction.
We can see from the table that the heights increase and then decrease; this means it cannot be an exponential function.
A quadratic function has a graph that is u-shaped. It will start out either increasing or decreasing, and then after the maximum or minimum is reached, it changes direction.
We can see from the table that this is what the heights do; this means it is a quadratic function.
Answer:
Simple random sampling survey method
Step-by-step explanation:
A simple random sampling is an unbiased survey technique Hence it will represent all the parts of the city's population.
In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process
