Let
be the n'the term of the sequence.
The first term of the sequence is
the second
is 8
the third term
is 4
the fourth term
is 2
the fifth term
is 1
We notice that:
i) the values of the terms are powers of 2, and decreasing:
ii) we also notice that the subscript integer of a, and the power of 2 at that term, add to 5.
thus the general term of the sequence is given by:
.
to fit the choices of the question, we can modify this formula as follows:
The average rate of change from n=1 to n=3 is defined as:
can be found using the general formula,
,
thus the average rate of change is (4-16)/2=-12/2=-6
Answer:
,
average rate of change=-6
Answer:
.25
Step-by-step explanation:
.5 times .5 or half of half is .25
<h2>
Answer:</h2>
The correct statement that is used when a scatter plot is constructed is:
The independent variable is the input variable and should be represented by the x-axis.
<h2>
Step-by-step explanation:</h2>
We know that while plotting a graph or a scatter plot the x-axis which is the horizontal axis of the plot represents the input value or the value of the independent variable and the output value i.e. the value of the function corresponding to the input value is represented by the y-axis.
As the value of the output is evaluated corresponding to the input value hence the variable y is also known as the dependent variable and is represented by the y-axis.
Answer:
D. 20
Step-by-step explanation:
20% of 20 is 4
$77 since 110 x 0.3 = 33. Then minus this value from 110, then the answer is $77
