Functions can be used to model real life situations.
The hose is 3.2 feet above the ground, at a horizontal distance of 4 fee
The function is given as:
At a horizontal distance of 4 feet, the value of x is 4
i.e.
Substitute 4 for x in f(x).
So, we have:
Evaluate the exponent
Open both brackets
Add -4.8 and 8
Hence, the hose is 3.2 feet above the ground

Answer:
II and III
Step-by-step explanation:
From statement II in the question, it is true that the standard deviations of two different samples from the same population may be the same. The population standard deviation is a fixed value calculated from every individual in the population. A sample standard deviation is calculated from only some of the individuals in a population.
Also from statement III, it is true that statistical inferences can be used to draw conclusions about the populations based on sample data. The mean of a population does not necessarily depends on the particular sample chosen. Therefore statement I is false.
Answer:
B
Step-by-step explanation:
4 (x - 7) - 2 (x + 1) = 10
x = 10
B. -2 (x - 7) + (x + 1) = 5
x = 10
your equation is equivalent to B!
C would be the right answer
A and B are correct because 96/100 is equivalent to 0.96, which is also 96%.
