So, your equation you have is y = 5x + 253.
They want to know <em>how many total pieces </em>you will have to put together after 45 more minutes.
So, you'll want to insert 45 in for x in the equation. Like so:
y = 5(45) + 253
Now you solve:
y = 225 + 253
y = 478
So this means you will have 478 pieces put together after another 45 minutes. There are 2573 pieces total, yes?
So, you do 2573-478
This equals = 2,095
So this means you'll still have 2,095 pieces to put together. Whew!

According to your statement, it's expression would be:
9 + 2x
So, your correct answer is 9 + 2x

Answer:
A. Statistic = A numerical measure that describes an aspect of a sample.
B.) Null hypothesis = A claim about a population parameter.
C.) Slope of the least square line = Marginal change in response variable.
D.) Population = All Objects or individual of interest
E.) P - value = Probability, assuming null hypothesis is true, that test statistic will take a value as extreme as observed.
F.) Coefficient of determination = Ratio of explained variation over total variation in y that can be explained by the regression equation using x as the explanatory variable.
G.) Z score = Distance from mean in terms of standard deviation units.
H.) Parameter = A numerical measure that describes an aspect of a population.
I.) Sampling distribution = Probability distribution of a sample statistic
J. Sample = Some individuals or objects of interest
