Answer:
the smallest sample size is 163
Step-by-step explanation:
The computation of the smallest sample size that meets these criteria is shown below:
n = (Z a/2 × Standard deviation ÷ Margin of error ) ^2
Zα/2 at 0.05% LOS is = 1.96 ( From Standard Normal Table )
Standard Deviation ( S.D) = 2.6
Margin of error i.e. ME =0.4
n = ( 1.96 × 2.6 ÷ 0.4) ^2
= 163
Hence, the smallest sample size is 163

Steps:
Find the 2D area of the two triangles:
- multiply 6 x 8 and divide it by 2 (this is the bottom triangle.)
** don't use 10 because it is the hypotenuse.
- 6 x 8 = 48
- 48 / 2 = 24 (you will need to use this twice since there are 2 triangles)
Now find the 2D area of the three rectangles
- first you have to convert 4 yd to feet.
**1 yd = 3 ft
~4 yd = 12 ft
-now multiply 12 x 10
- 12 x 10 = 120ft (use this 3 times since there are 3 rectangles)
Now add all those together:
120 + 120 + 120 + 24 + 24 = 408
This expression is not factorable which means the answer is 8x+7
Answer:
360°
Step-by-step explanation:
According to the properties of parallel lines, the following deductions can be made:
<a and <c are exterior angles of same side, therefore they are supplementary.
Thus,
m<a + m<c = 180°
<b and <d, are alternate interior angles, therefore, they are supplementary.
Thus, m<b + m<d = 180°.
The total numbers of degrees of a, b, c, d will all sum up to give 360°.
