So for number one you would start with parentheses (-2 x 4) and that would get you -8 and then you would forget about the parentheses and drop everything else down and now the problem would be -8 x 3 and remember anytime you have a number by parentheses it’s multiplication and that dot by the parentheses also stands for multiplication so -8 x 3 would get you -24. You could also look at it as positive 8 x 3 and that would get you 24 and then you could just add that negative sign to the 24

<h3>What are the parameters of a random variable?</h3>
A function of random variables utilized to calculate a parameter of distribution exists as an unbiased estimator.
An unbiased estimator exists in which the difference between the estimator and the population parameter grows smaller as the sample size grows larger. This simply indicates that an unbiased estimator catches the true population value of the parameter on average, this exists because the mean of its sampling distribution exists the truth.
Also, we comprehend that the bias of an estimator (b) that estimates a parameter (p) exists given by; E(b) - p
Therefore, an unbiased estimator exists as an estimator that contains an expected value that exists equivalent to the parameter i.e the value of its bias exists equivalent to zero.
Generally, in statistical analysis, the sample mean exists as an unbiased estimator of the population mean while the sample variance exists as an unbiased estimator of the population variance.
Therefore, the correct answer is an unbiased estimator.

<u>Given</u>:
Four lines are marked proportion, the length of TW can be determined by
<u>Value of a:</u>
Let us set the proportion for the given lines.
Thus, we have;
Thus, the value of a is 5.6
<u>Value of b:</u>
Let us set the proportion for the given lines.
Thus, we have;
Thus, the value of b is 5.
<u>Length of TW:</u>
The length of TW is given by
Thus, the length of TW is 13.6
Answer:
The answer to your question is c) y = (-2/3)x + 8/3
Step-by-step explanation:
Data
A (-2, 4)
B (1, 2)
Process
1.- Calculate the slope of the line
-Formula
m = (y2 - y1)/(x2 - x1)
x1 = -2 y1 = 4 x2 = 1 y2 = 2
-Substitution
m = (2 - 4) / (1 + 2)
-Simplification
m = -2/3
2.- Find the equation of the line
Formula
y - y1 = m(x - x1)
-Substitution
y - 4 = -2/3 (x + 2)
-Simplify
y - 4 = (-2/3)x - 4/3
y = (-2/3)x - 4/3 + 4
y = (-2/3)x - 4/3 + 12/3
-Result
y = (-2/3)x + 8/3
Answer:
Growing up i all ways have believed in Santa Claws it was so nice to get presents and clothes and it was something fun to look forward to every year and would also keep me on my best behavior. But as iv grown up, iv been told that Santa is fake when i heard this i was devastated, but now i realize that Christmas is not about toys and candy, it is about the Lord and Saviors birth. so i dont need a Santa Claws to have a good Christmas, i just need a family to spend time with.
