If a advertised sofa is $200 but the more costly sofa is $375, the average cost of such a sofa will be $200 is $243.75.
<h3>Define the term average of the number?</h3>
- An averaging is a single number calculated as the average of a set of numbers,.
- Typically calculated as the sum of a numbers divided by the total number of numbers in the set (the arithmetic mean).
You're planning to purchase a sofa from a furniture store that is having a sale on them.
Let x represent the sofa's price.
Advertised sofa's cost = $200
Expensive sofa's cost = $375
The advertisers are aware that when customers arrive at the store, one out of three switch to an expensive sofa that the one shown in the sale advertisement.
Average cost = 375 x 1/4 + 200 x 3/4
E(x) = 375 x 1/4 + 200 x 3/4
E(x) = 93.75 + 150
E(x) = 243.75
Thus, if a advertised sofa is $200 but the more costly sofa is $375, the average cost of such a sofa will be $200 is $243.75.

Answer:
y=-1/2x+3
Step-by-step explanation:
You're Y coordinate is going to equal the slope, or rise over run (aka rate of change.)
-1/2 is the rate of change, as the line goes up one, over negative two.
Then, add the Y-intercept, which is three, and you've got your equation!
Answer: 27.688
Step-by-step explanation:
The critical chi-square value 
depends on significance level (
) and degrees of freedom (df) .
Given significance level: () = 1% = 0.01
Degrees of freedom (df)= 13
From the chi-square table, the critical chi-square value for df = 13 and 
is 
Hence, the required critical value = 27.688
Just take 43 and subtract 7 to get 36
If you check, "7 more than 36" does equal 43
So 36
