Answer:
4
Step-by-step explanation:
To know the scale factor here, just know that 16/4 = 4, and 8/2 = 4 too, so the scale factor is 4.
Just that the respective sides need to have the same ratio.
Note, if it was from B to A, it'd be 1/4.
<u>Given: </u>
- Breadth of canvas is 22 inches.
- Length of canvas is 38 inches.
<u>To Find:</u>
- If kendra covered 30% of the canvas by painting red rose, what will be the area of canvas covered by red rose?
<u>Solution: </u>
To find the area of red rose, first we have to find the area of canvas.
★ Area of Rectangle = Length × Breadth
➝ 22 × 38
➝ 836 in²
So, Area of canvas is 836 inches².
★ Area of red rose:-
➝ 30% of 836 in²
➝ 0.30 of 836
➝ 250.8
Hence, Area covered by the red rose is <u>2</u><u>5</u><u>0</u><u>.</u><u>8</u>

★ Triangle => ½bh
★ Rectangle => Length × Breadth
★ Circle => πr²
★ Square => Side × Side
★ Parallelogram => Base × Height
★ Sphere => 4πr²
Answer:
see explaination
Step-by-step explanation:
1) Lets form the regression equation from the data results
Size = -1.633+ 0.4485*FamilyIncome + 4.2615*FamilySize - 0.6517*Education
-1.633+ 0.4485*40+ 4.2615*4 - 0.6517*13 =24.88
2) For the model to be reasonable, we must check the significant F stat from the anova table( see attachment)
From the table at attachment we can deduce; as the significant F is less 0.01 , we can safely conclude that the model is signifcant
3) all variables that have a p value less than 0.01 can be safely removed from the model as they do not contribute sigificantly from the model
so education can be removed from the model
You would rather look at the bar graph, easier to tell difference
