Answer:
8
Step-by-step explanation:
5 ( x - 3 ) + 2x = 41
5x - 15 + 2x = 41
5x + 2x - 15 = 41
7x - 15 = 41
7x = 41 + 15
7x = 56
x = 56 / 7
x = 8
Answer:
Given that The data to represent average test scores for a class of 16 students includes an outlier value of 78.
We can find sum of all 16 test scores = 84(16) = 1344
Outlier found = 78
If outlier is removed new sum = 1344-78 = 1266
Number of entries without outlier = 15
New average = 1266/12 =84.4
We find that average of new data increases.
Also whenever we remove outlier std deviation also would be reduced.
Step-by-step explanation:
The price of a painting in the year 2022 will be $ 568,000.
<h3>What is inflation?</h3>
A rise in the amount of a certain product or service is known as inflation.
Given data;
Cost of painting in the year 2021, P₁ = $560,000
Cost of painting in the year 2022, P₂ =?
The amount increases every year,x = $8,000
The cost of painting in the year 2022 is found as;
P₂ = P₁ + x
P₂= $560,000 + $8,000
P₂ = $ 568,000
Hence the price of a painting in the year 2022 will be $ 568,000.
