"(x^2y + 6)" is the one among the following choices given in the question that is one <span>of the factors of x^2y^3 - 11x^2y + 6y^2 - 66. The correct option among all the options that are given in the question is the first option or option "A". I hope that this is the answer that has actually come to your desired help.</span>
Answer:
d.
Step-by-step explanation:
A, B, and C ask questions that will be answered with different sets of data.
<u>example a:</u>
purple- 11 students
blue- 5 students
orange- 7 students
<u>example b:</u>
math- 27
history- 30
art- 25
<u>example c:</u>
history books: 12 lbs
math books: 15 lbs
science books: 10 lbs.
If it were to ask how many windows are there in each of the classrooms then it would be statistical.
you get the gist lol.
The probability of finding a substandard weld is: p = 5% =
0.05 <span>
We are given that the sample size: n = 300
Using the Poisson Distribution , the average number of welds (m) is:</span>
m = n*p =
m = 300 * 0.05 <span>
m =15 </span>
<span>
The standard deviation of welds (s) is calculated by:</span>
s = sqrt (m)
s = sqrt (15)
s = 3.873
<span>
<span>Assuming normal distribution, the z value corresponding to 30
sub standards is:
z =( X - Mean) / standard deviation
z =(30 - 15) / 3.873
z = 15 / 3.873
z = 3.87</span></span>
<span>
<span>The z value based on the standard normal curves has a maximum
value of 3.49. Beyond that z value of 3.49 would mean exceeding 100%. Therefore
z = 3.87 is not normal and definitely it is unusual to find 30 or more
substandard.</span></span>
Your original answer is right 33%
Answer:
x=-44
Step-by-step explanation:
y=22 x=-11
y=88 x=?
y/x=22/-11=-2
88/x=-2
-2x=88
x=-44
