Answer:

The equation of the regression line for the following data is:

y=2.4x+120.1

Step-by-step explanation:

We are given a set of data values in table form as:

           Day(x)                  Number of visitors(y)

               1                              120

               2                             124

               3                             130

               4                              131

               5                              135

               6                              132

               7                              135

Hence, when we draw a scatter plot with the help of these data points using the linear regression calculator we see that the regression line is a line with y-intercept as (0,120.1) and x-intercept as  (-50.04,0)

Hence, the regression line for the following data is:

                   y=2.4x+120.1

Answer:

y = 2.4x + 120.1

Step-by-step explanation:

Given table,

x              1             2              3              4             5               6          7

f(x)         120        124           130         131          135          132       135

Let the linear equation that shows the given table is,

y=mx + b

Where,

m =\frac{\sum xy - \sum x \sum y}{n\sum x - (\sum x)^2}

b=\frac{\sum y - m\sum x}{n}

Here, n = 7

Using graphing calculator,

m = 2.35714 ≈ 2.4,

b = 120.143 ≈ 120.1

Hence, the required equation would be,

y = 2.4x + 120.1

i.e. LAST option is correct.

2^x + 3^y = 9<br>2^x+1 - 3^y+1=8<br>find x and y​
Taya2010 [7]

Suppose :

2^x = t ..**&**.. 3^y = u

_____________________________

t + u = 9 × 3 3t + 3u = 27

=====》

2t - 3u = 8 2t - 3u = 8

+ __________

5t = 35

5 × t = 5 × 7

t = 7

&

u = 2

________________________________

Thus :

2^x = 7 ===》 x = Log _ 2 { 7 }

3^y = 2 ===》 y = Log _ 3 { 2 }
