Answer:
6(3) - 4 + (3)^2
Explanation:
We will do this on two steps:
1- get g(x)-f(x)
2- substitute with x = 3
Step 1:
f(x) = 4-x^2
g(x) 6x
g(x) - f(x) = 6x - (4 - x^2)
= 6x - 4 + x^2
Step 2:
Substitute with x = 3 as follows:
g(x) - f(x) at x = 3 is:
6(3) - 4 + (3)^2
Hope this helps :)
Answer: The average length of time that the 25 customers waited before leaving the bank. <u> e. Statistic</u>
The list of times for the 25 customers who left the bank. <u> f.Data </u>
All of the bank's customers <u> d. Population</u>
The 25 customers that the manager observed leave. <u> c. Sample</u>
The length of time a customer waits before leaving the bank. a. <u>Variable.</u>
The average length of time that all customers will wait before leaving the bank <u>a. Parameter</u>
Step-by-step explanation:
A data is a list of observations.
In statistics, a variable is an attribute that defines a person, place, thing, or thought.
A large group that have similar individuals as per the researcher's point of view is known as population, where its subset is known as sample.
The measure of certain characteristic in population is known as parameter, where for sample it is known as statistic.
Step-by-step explanation:
In×5z+In×7
=1.67z +1.95-8
=1.67z-6.05
Answer:
Let L be the length of the rectangle and w be the width of the rectangle.
"The lenght of a rectangle is one less than twice the width" means L=2W-1
Using perimeter formula of a rectangle which is P=2(L+W) you have:
P=2(L+W)
130=2(2W-1+W)
Solve equation above to find W
130=2(3W-1)
130=6W-2
130+2=6W
132=6W
W=22
From here you find L=2W-1=2x22-1=43
Only thing left is to find area A=LxW
