Part 5: Assessing the Relationship Between the Variables Use the reference summary and graphs for the least-squares regression model for temperature. 28. What is the t* critical value for a 95% confidence interval of the true slope of the linear model for temperature using this sample size? How many degrees of freedom here? 29. Estimate the true slope of the linear model for temperature using a 95% confidence level. Make sure to interpret your estimate as a slope.

x = 3 ± √(5+y)

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2

=240

=48

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
