Answer:
A rectangle has four right angles, A triangle has 3 sides, A square has 4 equal sides
Step-by-step explanation:
With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.
<h3>What is the surface area of a truncated prism?</h3>
The <em>surface</em> area of the <em>truncated</em> prism is the sum of the areas of its six faces, which are combinations of the areas of rectangles and <em>right</em> triangles. Then, we proceed to determine the <em>surface</em> area:
A = (12 cm) · (4 cm) + 2 · (3 cm) · (4 cm) + 2 · (12 cm) · (3 cm) + 2 · 0.5 · (12 cm) · (5 cm) + (5 cm) · (4 cm) + (13 cm) · (4 cm)
A = 48 cm² + 24 cm² + 72 cm² + 60 cm² + 20 cm² + 52 cm²
A = 276 cm²
With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.

Answer: (0.205905, 0.242095)
Step-by-step explanation:
We know that the confidence interval for population proportion is given by :-
, where 
= sample proportion
n= sample size
Let p be the proportion of complaints of identity theft .
As per given , we have
n= 1432
By standard normal table , z* = 1.645 for 90% confidence level.
Now , 90% confidence interval for p will be :
Hence, required confidence interval = (0.205905, 0.242095)

x=6
Answer:
B is the answer
The next 5 numbers are 10,13,3,12,2
Step-by-step explanation:
The next five numbers missing in the series are 10,13,3,12 and 2
We need to know about the order in which these numbers should be . It cannot be numerically arranged.
these numbers are spelled, as these numbers are in alphabetical order .so the last 5 missing numbers are 10,13,3,12 and 2 .
