The sum of the first 3 terms of an arithmetic sequence is 21,while their product is 315.determine these 3 terms
Sphinxa [80]
Given: 
Sum of arithmetic sequence is 21.
Product of arithmetic sequence is 315.

I did a manual computation. Arithmetic sequence means that there is a constant difference between the two consecutive numbers.

x + (x+2) + (x + 2 + 2) = 21
3x + 6 = 21
3x = 21 - 6
3x = 15
x = 15/3
x = 5    1st number

x + 2 = 5 + 2 = 7 2nd number

x + 2 + 2 = 5 + 2 + 2 = 9  3rd number.

5 + 7 + 9 = 21
5 x 7 x 9 = 315

Briefly explain how multiple regression enhances the two primary purposes of regression analysis.
maria [59]

The statistical goal of multiple regression analysis is to build a linear equation model that identifies the optimal weighted linear combination of independent variables in the study in order to optimally predict the reference variable.

Regression analysis is usually performed for one of two purposes. Predicting the value of the dependent variable of a person whose information about the explanatory variable is available, or estimating the effect of the explanatory variable on the dependent variable.

In multiple regression analysis, researchers can determine the strength of the relationship between the outcome (dependent variable) and multiple predictors, and the importance of each predictor in the relationship, often the effect of other predictors. It can be evaluated by statistically eliminating it.

Someone please help me on both the questions!!!
bonufazy [111]

Step-by-step explanation:

al nth term:

numerator:

=  {n}^{2}

denominator:

= n + 1

so nth term :

=  \frac{ {n}^{2} }{n + 1}

b). 1; 11; 27; 49

first difference: 10; 16; 22

second difference :6

formula for 1st difference:3a+b

formula for 2nd difference:2a

Therefore:

2a=6

a=3

3a+b=10

sub in a

3(3)+b=10

9+b=10

b=1

sub into quadratic formula

{an}^{2}  + bn  + c

(3) {(1)}^{2}  + (1)(1) + c = 1

3(1) + 1 + c = 1

3 + 1 + c = 1

4 + c = 1

c  = - 3

So Tn:

3 {n }^{2}  +  1n - 3
