Answer:
3421.19
Step-by-step explanation:
A=πr2=π·332≈3421.1944
-58.
To get this, first use the equation -b/2a. This will first find the maximum. After you find the maximum, input the answer into the original equation and solve for the minimum.
Hope this helps!
Answer:
A = 147 cm²
Step-by-step explanation:
A = πr²
A = (3)(7)²
A = 3(49)

Answer:
<h3>The F test for the overall significance of the regression tests the null hypothesis that <u>all slope coefficients are zero</u></h3>
Step-by-step explanation:
The F test for the overall significance of the regression tests the null hypothesis that <u>" all slope coefficients are zero "</u>
For :
- For the analysis of variance (ANOVA) F-test, the null hypothesis is that the true or population slopes of all the X variables are zero.
- There is no relationship between Y and any of the X variables .
- In that case,the null hypothesis implies that Y should simply be estimated using its mean

<h3>Therefore the option A) all slopes coefficients are zero</h3>
