The inequality for the given statement can be written as 5<span>z ≥ −25. The reason being that 5z is a minimum of - 25 or it is greater than - 25. The statement indicates this only. It is important to go through the statement minutely before answering the question. I hope that the answer has come to your help.</span><span />
Answer:
f(x)=19(2)^x
Standard form of exponential graph is f(x) = ab^x
Plugging in (0, 19), you get
19 = ab^0 -> 19 = a(1)
a=19
f(x)=19b^x
1216 = 19(b)^6
64=b^6
b=2
-> f(x) = 19(2)^x
Answer:

Explanation:
Here, we want to check if the given statement is a statistic or a parameter
While a parameter describes the whole population, a statistic describes a sample
From what we have in the question, the data completely describes each set of staff in the mathematics department
Thus, we can say it is a statistic
Its 39.58.... you may have missed one
Use the slope-intercept form to find the slopeand y-intercept.
Slope: 2
Y-Intercept: 9
