Find the equation of the line:

Mathematics
1 answer:
natta225 [31]1 year ago
5 0

Answer:

x=4.5.

The slope is undefined. Thus the y variable is irrelevant. It appears as though the line crosses through 4.5 on the x axis making the equation

x = 4.5

Twice a number (z) added to 21 is equal to 9 times the number added to 7. What is the number?
pickupchik [31]

Answer:

The number is  2

Step-by-step explanation:

Twice a number (z) = 2*z = 2z

Twice a number (z) added to 21  = 2z + 21

9 times the number added to 7 = 9z + 7

9z + 7 = 2z + 21

Subtract 2z form both sides

9z - 2z + 7 = 21

       7z + 7 = 21

Subtract 7 from both sides

7z = 21 - 7

 7z = 14

Divide both sides by 7

z = 14/7

z = 2

What is the difference between the following two regression​ equations? ModifyingAbove y with caret equals b 0 plus b 1 xy=b0+b1
Leona [35]

Answer:

A. The first equation is for sample​ data; the second equation is for a population.

Step-by-step explanation:

The first equation is y = b_0 + b_1x , this is the equation for sample data as the intercept (b_0) and the slope parameter(b_1)  both are calculated then we have got this and these values are not taken as given.

The Second equation is y = \beta _0 +\beta _1x , this is the equation for population data as we can't calculate these \beta _0 and \beta _1 as we take these values as given and also we do testing for \beta parameter using t test and it is sure that testing is always done on population data not on sample data.
