What are the answers?

Answer:

Option A The linear model on tar content accounts for​ 92.4% of the variability in nicotine content.

Step-by-step explanation:

R-square also known as coefficient of determination measures the variability in dependent variable explained by the linear relationship with independent variable.

The given scenario demonstrates that nicotine content is a dependent variable while tar content is an independent variable. So, the given R-square value 92.4% describes that 92.4% of variability in nicotine content is explained by the linear relationship with tar content. We can also write this as "The linear model on tar content accounts for​ 92.4% of the variability in nicotine content".

Final answer:

The Upper R squared or the coefficient of determination here represents the percentage of the variability in the nicotine content that can be explained by the tar content in the regression model, which in this case is 92.4%.

Explanation:

In this context, the meaning of Upper R squared is represented by option A. The linear model on tar content accounts for 92.4% of the variability in nicotine content. This indicates that 92.4% of the change in nicotine content can be explained by the amount of tar content based on the linear regression model used. This measure is also known as the coefficient of determination. Meanwhile, options B, C, and D are not correct interpretations of the R squared in this context. Both B and D wrongly relate the percentage to the predictability of the data points and option C incorrectly associates this percentage with the residual magnitude.

Answer:

5 feet and 60 inch

Step-by-step explanation:

5 feet and 60 inches

Step-by-step explanation:

Answer:

1= 29

2= 61

3= 90

4= 29

5= 90

Step-by-step explanation:

A rectangle has 4 - 90 degree angles. This means angles 3 and 5 are 90. This means the other angle will be split into two parts that add together to 90. If one is 61 then the other is 29. This is angle 4. This means angle 2 is 61 and angle 1 is 29 because rectangles have parallel sides.

Answer:

Shifts 4 units down --->

Stretches f(x) by a factor of 4 away from x-axis--->

Shifts f(x) 4 units right--->

Compress f(x) by a factor of 1/4 toward the y-axis --->

Step-by-step explanation:

We are given

We need to match the transformations.

1) shifts f(x) 4 units down.

When function f(x) shifts k units down the new function becomes f(x)-k

In our case

So, Shifts 4 units down --->

2) Stretches f(x) by a factor of 4 away from x-axis

When function f(x) is stretched by a factor of b away from x-axis the new function becomes f(bx)

So, Stretches f(x) by a factor of 4 away from x-axis--->

3) Shifts f(x) 4 units right

When function f(x) shifts h units right the new function becomes f(x-h)

So,  Shifts f(x) 4 units right--->

4) Compress f(x) by a factor of 1/4 toward the y-axis

When function f(x) is compressed by h factor of a toward the y-axis the new function becomes h.f(x)

Compress f(x) by a factor of 1/4 toward the y-axis --->

(Option Not given)

(If we compress f(x) by a factor of 4 towards y-axis we get g(x)=8x-24)

Answer:

0 and arctan(0.5)

Step-by-step explanation:

if sin2x=2sinx*cosx and 1=sin²x+cos²x, then

cos²x+2sinxcosx-sin²x-cos²x=0;

2sinxcosx-sin²x=0; (to divide by cos²x)

2tanx-tan²x=0;
