Answer:
216 in²
Step-by-step explanation:
a = bh
a = 18 * 12
a = 216
The surface area of triangular prism is 117.12 mm²
<u>Explanation:</u>
Base side, a = 9 mm
Base side, b = 6.6 mm
Base side, c = 5.2 mm
Height, h = 4 mm
Total surface area = ?
We know,
Surface area, A = 2 Ab ( a+b+c) h
Ab = √s(s-a) (s-b) (s-c)
s = a+b+c/2
Solving for A
A = ah + b h + ch + 1/2 √ -a⁴ + 2(ab)² + 2(ac)² - b⁴ + 2 (b c)² - c⁴
A = 9.4 + 6.6 X 4 + 5.2 X 4 + 1//2 √ -9⁴ + 2(9 X 6.6)² + 2(9 X 5.2)² - (6.6)⁴ + 2 (6.6 X 5.2)² - (5.2)⁴
A = 117.12 mm²
Therefore, the surface area of triangular prism is 117.12 mm²
Answer:
The 2nd one.
Step-by-step explanation:
First, put the numbers in order from least to greatest. This isn't required, but it makes it easier.
3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20
Then, for each range of shows watched (0-5, 6-11, etc.) from the graph, count how many numbers from the list fit into that range.
Use the process of elimination:
In 3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20, numbers from 0-5 show up 8 times, so you can rule out the last 2 graphs. Numbers 12-17 show up 2 times, so the first one is incorrect. That leaves you with the second histogram.
Answer:
Descriptive
Step-by-step explanation:
Descriptive statistics uses the data that helps to analyse, describe, and elaborate data accurately. It also provides information regarding the population through graphs or tables. Four types of descriptive statistics are measures of frequency, measures of central tendency, measures of dispersion, and measures of position.
The given example in question is <u>descriptive statistics</u>.
