Answer: C - 600cm^2
Step-by-step explanation:
Area of one triangle:
(12)(5) ÷ 2 = 30
Area of two triangles:
30 x 2 = <u>60</u>
Area of top rectangle:
Step 1: Figure out side length of triangle by using pythagorean:
√a^2 + b^2 = c
√(5)^2 + (12)^2 = c
√25 + 144 = c
√ 169 = c
13 = c
Step 2: Find area of top rectangle:
(18) x (13)
<u>234</u>
Find area of bottom rectangle:
(18) x (12)
<u>216</u>
Find area of back rectangle:
(18) x (5)
<u>90</u>
Add all the underlined numbers:
Area of two triangles + Area of top rectangle + Area of bottom rectangle + Area of back rectangle
60 + 234 + 216 + 90 = 600cm^2
Answer:
The sample size is very large
Step-by-step explanation:
For Incorrect option we have,
When making the comparison between the sample proportion that is 0.201 and the hypothetical proportion that is 0.20. In this way it is possible to conclude that as the sample size increases, it also tends to normal. In this way it can be concluded that it is a non-aberrant sample. The sample proportion and the hypothetical proportion are almost equal.
For correct option we have that
So,
The sample size is greater than 30.
Here, sample size is very large . Hence difference is highly significant.
Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
Triangle ABC is similar to Triangle CBD by AA Similarity theorem
Remember that
If two triangles are similar, then the ratio of its corresponding sides is proportional
so
substitute the given values
Remember that
therefore
Positive Integer factors of 43904 = 2, 4, 8, 16, 32, 64, 128, 7, 896, 6272, 43904 divided by 2, 2, 2, 2, 2, 2, 2, 7, 7, 7, gives no remainder.
