Step-by-step explanation:
Equation that fits best in data is
.Although there are no options , kindly match this equation to options available!
<u>Step-by-step explanation:</u>
We are given a graph with y & x-axis , with 4 points given and best fit for data can be found out by joining points . On joining points , we see that best fit is a line . General equation of a line is :
,
where m = slope of line & c = intercept.
Let's calculate slope m :
Consider any two given points , let's have ( 4,0) & (3,30) :
Slope = m
⇒ m = 
⇒ m = 
⇒ m = 
So , equation now becomes :
⇒ 
at x = 0 we have y = 4



Therefore, equation that fits best in data is
.Although there are no options , kindly match this equation to options available!
Answer:
<u>Therefore, the value of x is 5.</u>
Step-by-step explanation:
We can match each equation to find the solutions.



Now, we need solve this quadratic equation.

<u>Therefore, the value of x is 5.</u>

By convention, the first term of a sequence starts with n = 1 instead of n = 0. This is so n = 1 matches with 1st, n = 2 matches with 2nd, and so on.
In contrast, the y intercept always occurs when x = 0. So something like y = 3x+5 has a y intercept of 5 when you plug in x = 0.
An arithmetic sequence like f(n) = 2n+7 has its first term when n = 1. So the first term would be f(1) = 2(1)+7 = 9 instead of 7 as Hank claims.
