To solve this question, you have to take the 2D shape and divide it up into 6 boxes, of which you find the area of each. For easier reference, here's a picture where I've numbered the boxes.
Box 1: Nothing special here, just 25*12= 300 cm²
Box 2: The height of box 2 is obvious but the length is found from the above box. 25*18= 450 cm²
Box 3: Box 3 is the opposite of box 2, with an obvious length, but a width which is found from box 2. 12*18= 216 cm²
Box 4: Box 4 receives its height from box 2 and its length from box 6. 25*18= 450 cm²
Box 5: Box 5 has an obvious length but receives its height yet again from box 2. 12*18= 216 cm²
Box 6: Box 6's parameters are both obvious. 25*12= 300 cm²
The next step is to add the area of all the sections. 300+450+216+450+216+300= 1932 cm²
I hope this helped you!
Answer:
10 Square Inches
Step-by-step explanation:
<u>Trapezoid</u>
Base =12 inches
Height =10 inches
Top side= 10 inches.
Area of a Trapezoid
Area of the Trapezoid=110 Square Inches
<u>Rectangle</u>
Base = 12 inches
Height =10 inches.
Area of a Rectangle=Base X Height
=12 X 10
=120 Square Inches
<u>Difference in Area between the two packages</u>
Difference=Area of Rectangle-Area of Trapezoid
=120-110
=10 Square Inches
Answer:
a) (0.576, 0.624)
Step-by-step explanation:
Given that the sample proportion (p) = 60% = 0.6, sample size (n) = 900, confidence (C) = 85%
α = 1 - C = 1 - 0.85 = 0.15
α/2 = 0.075
The z score of α/2 (0.075) corresponds with the z score of 0.425 (0.5 - 0.075) which is equals to 1.44, hence
The margin of error (E) is:
The confidence interval = p ± E = 0.6 ± 0.024 = (0.576, 0.624)
