Multiply the denominator by the whole number and add the numerator.
so it's
11÷-11= -1
Answer:
A = 7
B = 4

If u wanna know how i got this answer plz look at the comments below since it will delete my answer U-U
Answer:
F. Hyperbola
Step-by-step explanation:
In each napped, you'll have a parabola, combined they form an hyperbola.
It's one of the various shapes that can be produced by a plane intercepting a right circular cone, as you can see in the attached picture.
Each plane intersection is different, based on the angle and the position it passes through.
I hope that helps.
I'd suggest using "elimination by addition and subtraction" here, altho' there are other approaches (such as matrices, substitution, etc.).
Note that if you add the 3rd equation to the second, the x terms cancel out, and you are left with the system
- y + 3z = -2
y + z = -2
-----------------
4z = -4, so z = -1.
Next, multiply the 3rd equation by 2: You'll get -2x + 2y + 2z = -2.
Add this result to the first equation. The 2x terms will cancel, leaving you with the system
2y + 2z = -2
y + z = 4
This would be a good time to subst. -1 for z. We then get:
-2y - 2 = -2. Then y must be 0. y = 0.
Now subst. -1 for z and 0 for y in any of the original equations.
For example, x - (-1) + 3(0) = -2, so x + 1 = -2, or x = -3.
Then a tentative solution is (-3, -1, 0).
It's very important that you ensure that this satisfies all 3 of the originale quations.
The histogram which represents the data set with the smallest standard deviation is: C. Squad 3.
<h3>What is a histogram?</h3>
A histogram can be defined as a type of chart that's used to graphically represent a set of data points into user-specified ranges, especially through the use of rectangular bars.
Basically, standard deviation is a statistical tool which can be used to determine the measure of spread for the data represented in a histogram, especially based on the frequency of the specified ranges.
In this scenario, the histogram which represents the data set with the smallest standard deviation is Squad 3 because it has the least frequency on the y-axis.
