Answer:
2p^2−5q+7
Step-by-step explanation:
Let's simplify step-by-step.
5−p2−4q−(−2+q−3p2)
Distribute the Negative Sign:
=5−p2−4q+−1(−2+q−3p2)
=5+−p2+−4q+(−1)(−2)+−1q+−1(−3p2)
=5+−p2+−4q+2+−q+3p2
Combine Like Terms:
=5+−p2+−4q+2+−q+3p2
=(−p2+3p2)+(−4q+−q)+(5+2)
=2p2+−5q+7
Answer:
=2p^2−5q+7
Answer:
the answer is false because Every system of linear equations has exactly one solution, no solution or infinite number of solutions
Part A
For Todd's class, we have this given info:
- mu = 70.6 = population mean of math scores
- sigma = 11.9 = population standard deviation of math scores
Compute the z score for x = 74.6
z = (x-mu)/sigma
z = (74.6 - 70.6)/(11.9)
z = 0.34 approximately
Side note: Convention usually has z scores rounded to two decimal places. If your teacher instructs otherwise, then go with those instructions of course.
<h3>Answer: 0.34</h3>
======================================================
Part B
For Garret's English class, we have:
Compute the z score for x = 68.8
z = (x-mu)/sigma
z = (68.8 - 63.7)/(8.6)
z = 0.59 approximately
<h3>Answer: 0.59</h3>
======================================================
Part C
Garret has the higher z score, which means that Garret did relatively better to his classmates compared to Todd's performance (in relation to his classmates). The z score is the distance, in units of standard deviation, the score is from the mean. Positive z values are above the mean, while negative z values are below the mean.
<h3>Answer: Garret did relatively better</h3>
193.5m is the area because you have to isolate the different shapes in the overall figure, and find the area of those first, once you have found them all you need to add them together
if the diameter of a circle is 15, its radius is half that or 7.5.
