Answer:
The answer to your question is 780 ft²
Step-by-step explanation:
- Divide the figure into two sections an upper part and a lower part.
- Area of the upper part = base x height
= 40' x 18'
= 720
-Area of the lower part
base = 40' - 30' = 10'
height = 24' - 18' = 6'
Area = 10 x 6 = 60
- Total area = Area Upper part + Area lower part
= 720 + 60
= 780 ft²
Answer:
<em>The sample size 'n' = 721</em>
<em>Number of cars 'n' = 721</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<em>Given Population proportion 'p' = 0.40</em>
<em>Given Margin of error = 0.03</em>
<em>90% of level of significance </em>
<em> </em><em></em>
<em>The Margin of error is determined by</em>
<em></em><em></em>
on calculation , we get
0.03√n = 0.8058
squaring on both sides , we get
n = 721.45≅721
<u><em>conclusion</em></u>:-
<em>The sample size 'n' = 721</em>
<em>Number of cars 'n' = 721</em>
The three terms are 3d/4 and -1/2 and 7. Multiply each of these terms by 4. Why 4? This is the lowest common denominator (LCD) of the fractions. If we multiply all the terms by the LCD, then the denominators will cancel out. This will get rid of the fractions.
4 times 3d/4 = 3d
4 times -1/2 = -2
4 times 7 = 28
After multiplying each term by 4, we end up with the equation 3d - 2 = 28
Let's solve for d
------------------------
3d - 2 = 28
3d-2 + 2 = 28+2 .... add 2 to both sides
3d = 30
3d/3 = 30/3 .... divide both sides by 3
d = 10
------------------------
The final answer is d = 10
It is incorrect it has to be 900 applicants not 885.
