22 houses can be cleaned in 11 hours.
Step-by-step explanation:
It is given that;
6 hours = 12 houses cleaned
1 hour = ![\frac{12}{6}\ houses\ cleaned\\](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B6%7D%5C%20houses%5C%20cleaned%5C%5C)
1 hour = 2 houses cleaned
In 1 hour, 2 houses can be cleaned, therefore,
11 hours = Time*houses cleaned in one hour
11 hours = 11*2 =22 houses cleaned
22 houses can be cleaned in 11 hours.

Answer: Y=8
Step-by-step explanation:
considering you are solving for Y and 4/2 is a fraction you would solve the equation like so:
Y - 4/2 = 10
Y - 2 = 10
you then add 2 to both sides of the equation and cancel it out from the left side leaving only Y.
Y = 8
Answer: E. Parametric estimating
Step-by-step explanation:
A parametric estimate is the estimating process that uses a statistical relationship between past project's data and other variables to give an estimation for the parameters such as duration ,cost and budget.
It is based on parameters that summarize the risk , costs of algorithm , project , process , complexity and service.
It can create a greater level of accuracy.
Therefore , Parametric estimating is an estimating technique that uses a statistical relationship between historical data and other variables to calculate an estimate for activity parameters such as duration and cost.
Hence , the correct answer is E. Parametric estimating.
X = 7
y = 8
As 7 is the median as it would be the middle number and the mean would now be 7 as well
