The parallelogram below is being covered with carpet. The carpet is priced at $2.80 per square meter. How much will it cost to c
1 answer:
Answer:
It will cost $79.38 to carpet the shape
Explanation:
Find the diagram of the parallelogram attached
Area of a parallelogram = Base * Height
Given
Base = 8.1m
Height = 3.5m
Area of the parallelogram = 8.1*3.5
Area of a parallelogram = 28.35m²
Since 1m² = $2.80
28.35m² = x
Cross multiply
x = 28.35 * 2.80
Hence it will cost $79.38 to carpet the shape

Answer: 0.1
Step-by-step explanation:
Given : A Houston department store sampled 80 items sold in January and found that 8 of the items were returned.
In other words, sample size : <em>n</em>=1040
Number of items returned : <em>x</em>= 8
Let <em>p</em> be the proportion of items returned for the population of sales transactions at the Houston store.
As per sample , the sample proportion of items returned for the population of sales transactions at the Houston store is :
As we know that , <em>the sample proportion is the best estimate of the population proportion.</em>
Therefore,a point estimate of the proportion of items returned for the population of sales transactions at the Houston store is 0.1.
