Answer #3 is correct
6 is the common ratio (r)
first term is -2/3 (a)
the general equation is f(x)=a(r)^x-1
so plug in the number
f(x)=-2/3(6)^x-1
"Mean" is another way of saying average.
To find the average/mean, add up all the numbers and then divide by the amount of numbers that are in the data set.
Step 1: Add the numbers.
0 + 1 + 1 + 2 + 5 + 6
= 15
Step 2: Divide the sum by the amount of numbers in the set.
There are 6 numbers in the data set.
Their sum is 15.
Divide 15 by 6.
15 / 6
= 2.5
Answer:
The mean, also known as average, of this data set is 2.5.
Hope this helps!
Answer:
The answer to your question is -4 to infinite
Step-by-step explanation:
Range is the set of all the possible values of the dependent variable when substitute the domain in the function.
On a graph, we find the range, looking at all the y-axis
In this graph, y has values from -4 to infinite, then, the range is [-4, ∞)
Answer:
apart from using the hoc to predict the college students gpa, some other variables can be used
1. the students intelligent quotient
2. ability to remember
3. study time
4. gym practice
Step-by-step explanation:
<u>1. the students intelligent quotient</u>
<u>gpa</u><u> </u>has a positive relationship with iq. they are both directly related. The more the iq of a a student, the greater is his ability to understand and have a good gpa. the slope will therefore be positive and be in an upward direction.
2. <u>ability to remember</u>
the gpa of students who have a good ability to remember but do not have a good grasp of the subject may not be high. the slope would be in a slightly upward direction
3. <u>study time</u>
gpa and practice have a positive relationship. the more a student studies, the more likelihood exists of having a better gpa. the slope would be upward bound.
4. <u>gym</u><u> </u><u>practice</u>
gpa and gym practice are not related so the slope would be in a downward direction.
when interpreting the direction of relationship after carrying out such an analysis, it is useful to watch out for the accompanying signs of the variables. if the sign of the beta coefficient is positive then a positive relationship with the dependent variable exists.
Log_(10)(x² - 4x + 7) = 2
Take the base 10 anti log of both sides.
x² - 4x + 7 = 10² = 100
x²- 4x - 93 = 0
Quadratic Formula
x = [4 ± √(4²-4(1)(-93))]/[2(1)] = [4 ± 2√97)]/2 = 2 ± √97
