Give your answer as a fraction in its
simplest form.
profit p(x) is the difference between revenue…
Answer:
x^4-3x^3+x^2-4
mrk me brainliest plz
Step-by-step explanation:
Given the following functions
R(x) = 2x^4 – 3x^3 + 2x – 1 and
C(x) = x^4 – x^2 + 2x + 3
We are to find the profit function P(x)
P(x) = R(x) - C(x)
P(x) = 2x^4 – 3x^3 + 2x – 1 - ( x^4 – x^2 + 2x + 3)
P(x) = 2x^4 – 3x^3 + 2x – 1 - x^4 + x^2 - 2x - 3
Collect the like terms
P(x) = 2x^4-x^4-3x^3+x^2+2x-2x-1-3
P(x) = x^4-3x^3+x^2+0-4
P(x) = x^4-3x^3+x^2-4
Hence the required profit function P(x) is x^4-3x^3+x^2-4
Answer:
i think its x^4-3x^3+x^2-4

The right triangle has a perimeter of 40 centimeters.help pls
Answer:
C
Step-by-step explanation:
P= side 1+ side 2 + side 3
40-(17+8)=15
15x8/2=60
Area of triangle, who has perimeter of 40 centimeters is 60 cm².
What is Area of Triangle?Area of a Triangle = A = ½ (b × h) square units
where b and h are the base and height of the triangle, respectively.
Given: Perimeter= 40cm
Now, 17+8+side=40
side= 40-25
side= 15 cm
Now, Area of triangle,
=1/2*b*h
= 0.5*15*8
= 60 cm²
Hence, Area of triangle= 60 cm².

Solve for x.
3x + 13,
H
6x +
x = [?]
Enter
Answer:
Step-by-step explanation:
you know some things about the two angles they are the complimentary parts of just one of those perpendicular lines. so you can say
180 = (6x + 5) + (3x+13)
180 = 9x +18
162 = 9x
18 = x
Answer:
Solution given;
6x+5+3x+13=180(sum of exterior angle is 180°)
9x=180-18
x=162/9
x=18 is a required answer.
In Test A, suppose you make 100 experimental measurements of some quantity and then calculate mean, standard deviation, and standard error of the numbers you obtain. In Test B, suppose you make 1000 experimental measurements of the same quantity and you again calculate mean, standard deviation, and standard error.
How would you expect the mean, standard deviation, and standard errors found in Test A and Test B to compare? (You can use the Excel simulation and change the "Number of Experiments" parameter to investigate this yourself.
A.) I would expect the means, the standard deviations, and the standard errors in Test A and Test B to be about the same.
B.) I would expect the means of the two tests to be about the same, but both the standard deviation and the standard error in Test B should be smaller than in Test A
C.) I would expect the means of the two tests to be about the same, but both the standard deviation and the standard error in Test B should be bigger than in Test A
D.) I would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be smaller than in Test A.
E.) would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be larger than in Test A.
Answer:
D.) I would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be smaller than in Test A.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
By the Central Limit Theorem:
Both tests, A and B, are of the same quantity, so they have the same mean and standard deviation. However, since the standard error is inversely proportional to the sample size, and test B has a greater sample size than test A, the standard error in test B should be lower, and thus, the correct answer is given by option D.

find perimeter of each polygon. Assume that the lines which appear to be tangent are tangent. Part 1. NO LINKS OF ANY KIND.
9514 1404 393
Answer:
7) 57.8
8) 73.8
Step-by-step explanation:
The tangents from a given point are the same length. This means the perimeter can be calculated as twice the length of one side plus twice the length of an opposite tangent.
7) P = 2(22.2 +6.7) = 57.8
8) P = 2(22.9 +14) = 73.8

Answer:
x = 4 & 2
Step-by-step explanation:
-2x²+12x-16 = 0
-2(x²-6x+8) = 0 // Factor what's in the parentheses
-2(x-4)(x-2) = 0
-2(x-4) = (-2x+8)
(-2x+8) = 0 // Subtract 8 on both sides
-2x = -8 // Divide both sides by -2
x = 4
x-2 = 0 // Add 2 on both sides
x = 2
