200 screen 1
125 screen 2
175 screen 3
Distribution of 500 visitors =100% attendees.
We remove a zero to find 1/10th. By converting 500 } 50/10 = 10 x 50
Step-by-step explanation:
when you add up; 40/10 + 25/10 = 4.0 + 2.5
and show 7.5 is the same as a + b + 1 x 100
and above 7.5 = 175/100 = 1 .75
Or use the counter x = multiply by 50
40/10 + 25/10 = 6.5
6.5-10 = 3.5
x =3.5 x 50
For this last one we can pose new question where 300 visitors was the original total then create new data for new question.
where x = multiply by 30 and create all to tenths etc.
We subtract the shown tenths only to find the total
Then same will apply above with new data.
Answer:
B
Step-by-step explanation:
A is 3-2 which is 1, not 5.
C is 3(2), which is 6, not 5.
D is 6, which is not 5.
-hope it helps
Answer:
A.
While D is partially correct, A is the way to go, because samples are easier to collect than whole populations. The internet quotes, "It is a much quicker process and is more time efficient." This proves the theory why A is the correct answer.
Answer:
Step-by-step explanation:
Split the trapezoid as pictured below
Find its height and the upper base, then find the area of the trapezoid.
There are 3 pieces, two of them are 45°×45° and 30°×60°×90° triangles
- The ratio of sides of a 30°×60°×90° triangle is 1 : √3 : 2
- The legs of a 45x45 triangle are equal
<u>The above mentioned properties give us:</u>
- h = 16/2 = 8 m
- b = 8√3 ≈ 13.85 m
- a = h = 8 m
<u>Now find the area:</u>
- A = 1/2( 13 + 8 + 13.85 + 13)*8 = 191.4 m²
Correct choice is B
