To find the equation of a trend line, It is important to find the X axis and Y axis, Once x axis and y axis is found if there is an association between x axis and y axis, We use linear equation to produce the trend line. Linear regression or algorithm called as OLS (Ordinary least square). Y= mx +c
y = dependent variable, x = independent variable , constant = c , m = y2-y1/x2-x1.
Step-by-step explanation:
- Scatter plot is to find association of two different variable.
- Trend line is the equation between xaxis and y axis.
- Prediction is best way to form equation.
- Linear regression y=mx +c
- Equation helps in predictive modelling between next best form.
- Y is a dependent variable or example sales.
- X can be n number of variable involved in the association rule.
- Linear regression is starting phase of data analysis.
- C = constant there is a certain point, where system has been started.
- Stock market did not start from 0 it started at a certain point.
Answer:
the answer is the mean
Step-by-step explanation:
you add all the numbers then divide by how many you have
Answer: x2+17x+3
Step-by-step explanation:
2x2+7x−x2+10x+3
=2x2+7x+−x2+10x+3
Combine Like Terms:
=2x2+7x+−x2+10x+3
=(2x2+−x2)+(7x+10x)+(3)
=x2+17x+3
Answer:
$5659.11
Step-by-step explanation:
We are given;
- Time of loan maturity is 5 years
- Rate of compound interest is 7% compounded quarterly
- Principal amount of the car is $4000
We are required to determine the total amount he paid at the end of 5 years..
The concept being tested is compound interest;
We are going to use the compound interest formula;
Amount = P(1+r/100)^n
Where P is the the principal amount
r is the rate of interest
n is the interest periods
In this case;
n = (5 × 4) = 20
r = 7 ÷ 4 = 1.75 ( as the money was compounded quarterly)
Thus;
Amount =$ 4000 ( 1 + 1.75)^20
= $4000 (1.0175)^20
= $5659.11
Therefore, the money that Joe will have paid at the end of 5 years is $5659.11
The answer is 2.9 x 10^-3. You can just divide 5.8 and 2. You get 2.9. After when ever you are Dividing exponents you have to subtract the power. So (-6)-(-3) is just -3. So when you put it together you get 2.9 x 10^-3
