Answer:
thats to much im stuck
Step-by-step explanation:
Answer: x = -39
Step-by-step explanation:
85= -6x+7+4x combine like terms (-6x, 4x)
85= -2x+7 subtract 7 from both sides
78= -2x divide both sides by -2
x= -39
Answer:
With representing the slope we have that:
And we are interest on this case the interpretation about the slope and we can conclude that:
For every unit increase in literacy rate (percent of the population that is literate) the age difference (husband minus wife age) falls by 0.0437 units, on average.
Step-by-step explanation:
For this case we have that the regression model adjusted between age difference (husband minus wife age) representing the y variable and literacy rate (percent of the population that is literate) representing the variable x is given by:
where
And we know that the method used in order to adjust the regression line was least squares.
For this case our dependent variable is y = age difference (husband minus wife age) and the independent variable is x=literacy rate (percent of the population that is literate)
If we compare the regression model adjusted with the linear regression model:
With representing the slope we have that:
And we are interest on this case the interpretation about the slope and we can conclude that:
For every unit increase in literacy rate (percent of the population that is literate) the age difference (husband minus wife age) falls by 0.0437 units, on average.
Answer:
The equation is:
After
Step-by-step explanation:
This situation can be represented by an exponential growth equation of the form
Where a is the initial amount
b is the growth rate
t is the time in months
In this case the initial amount is $ 3. Then
if she initially saves $3 and plans to double the amount she saves each month then
The bike Jane wants is $1,536 at the local bike shop.
Then
The equation is:
Now we solve the equation for t
