Based on the end behaviors, which graph is the graph of f(x) = -2x4 − 4x3 + x2 + x + 3?
Answers
Given:
The function is
[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]
To find:
The graph of the function by using the end behaviors.
Solution:
We have,
[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]
The degree of the polynomial is 4 which is even and the leading coefficient is -2, which is negative. So,
[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]
[tex]f(x)\to -\infty\text{ as }x\to \infty[/tex]
It means, the graph of the function approaches to negative infinity on the both ends.
Therefore, the correct option is C.

The surface area of a box is 2(h * W) + 2(h * L) + 2(W * L)
h = height
W = width
L = length
length x width x height
length = 5 in
width = 2 in
height = 10 in
2(10 * 2) + 2(10 * 5) + 2(2 * 5)

Answers
Answer:
y = 4x - 2
Step-by-step explanation:
Given: 4x=2+y
First, subtract 2 on both sides to isolate out y. (Slope-intercept form is y=mx+b)
Once subtracted, you get: 4x-2=y
Rearrange it, and you get: y=4x-2

Perimeter of a rectangle with 16in length and 14in width is 60 in.
Perimeter of a rectangle = 2(l+b)
here l = length and b= width
Given : l= 16 in and b= 14 in
perimeter = 2(l+b)
= 2(16+14)

Answer:
The ordered pair works for the first equation on the top, but not the second equation on the bottom.
Step-by-step explanation:
You have to plug in the x and y values into the equations:
x - 2y = -6
2 - 2(4) = -6
That equation works.
...now for the next one...
3x + 2y = 12
3(2) + 2(4) = 12
That equation doesn't work.
Hope this helps!
Observe:
2-2(4)=-6
-6=-6 this is a true statement
3(2)-2(4)=12
6-8=12
-2≠12 this is a false statement
Therefore the solution 2,4 doesn’t apply to the system since it only applies to one of the equations

The probability of rolling a 2 on a number cube is 1/6 . If you were to roll the
cube 30 times, you would expect to get a 2 around 5 times (1/6 · 30 = 5).
You simulate 30 rolls. How many 2s would make you question your model?
A. 14
B. 5
C. 2.
D. 8
Answers
Answer: a
Step-by-step explanation:
If a cube is rolled by 30 times then 5 times 2s will make the question the model.
What is probability?Probability is the occurrence of any event or how likely an event can happen.
Mathematically probability = the number of desired outputs by the number of the possible outcomes.
In the number cube, there are six faces above each of them written one to six later.
The probability of getting 2 at once time will be 1/6 since the number of desired output is only one and possible outcomes are six.
Mathematically(Theoretically) if we roll the cube 30 times then the number of 2s will be 1/6 × 30 = 5 times.
If experimentally if we roll dice and the number of 2s came 5 times then our question will become a model.
So by 5 times, 2s will make the question model.

From a sample of 300 cat owners, the researchers randomly assigned 150 cat owners to use medication R on their cats and the remaining cat owners to use medication S. For the cats using medication R, 88 percent had no fleas. For the cats using medication S, 90 percent had no fleas. Which of the following is the most appropriate method for analyzing the results?
A two-sample z -test for a difference in population proportions
A two-sample z-test for a difference in sample proportions
A one-sample z-test for a sample proportion
A one-sample z-test for a population proportion
A one-sample z-test for a difference in sample proportions
Answers
Answer:
A) A two-sample z -test for a difference in population proportions
Step-by-step explanation:
To determine whether a difference in proportions is significant, the two-sample z-test for a difference in population proportions is the most appropriate method for the analysis.
The most appropriate method for analyzing the results is A. A two-sample z-test for a difference in population proportions.
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter.
In this scenario, we have two different treatments (medication R and S) applied to two separate samples (150 cat owners each) and we want to determine if there is a significant difference in the proportion of cats with no fleas between the two groups.
This is a classic scenario for a two-sample z-test for a difference in population proportions, which tests the hypothesis that the difference in proportions between two independent populations is equal to zero.
Thus, a two-sample z-test for a difference in population proportions.
Hence, the correct answer would be option (A)
