Answer:
P(x)= x ^4-3x^3+x^2-4
Step-by-step explanation:
Given data
R(x) = 2x ^4-3x^3+2x-1
c(x)=x^4-x^2+2x+3
We know that
P(x)=R(x)-C(x)
Hence
P(x)= 2x ^4-3x^3+2x-1-(x^4-x^2+2x+3)
open bracket
P(x)= 2x ^4-3x^3+2x-1-x^4+x^2-2x-3
Collect like terms
P(x)= 2x ^4-x^4-3x^3+x^2-2x+2x-3-1
P(x)= x ^4-3x^3+x^2-4

Answer:
64 pretzels = 16 oz
16 pretzels = 4 oz
1 pretzel = .25 oz
4 pretzels = 1 oz
Step-by-step explanation:
If you know that 64 equals 16 ounces than you can divide 64 by 16 to get 4. This means that one ounce equals four pretzels. Then you can multiply 1 oz by 4 and 4 pretzels by 4 to get 16 pretzels that equal 4 oz. If 4 pretzels equals 1 oz then 1 pretzel equals 1 oz divided by 4.

If the dimensions of a cylinder are doubled, then its volume is quadrupled.
True
False
Answer:
The answer is False.
If the dimensions of a cylinder are doubled, then its volume is quadrupled. The statement is false.
What is the volume of a right circular cylinder?Suppose that the radius of the considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
The right circular cylinder is the cylinder in which the line joining center of the top circle of the cylinder to the center of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.
If the dimensions of a cylinder are doubled, the radius will become 2r, and the height will become 2h.
Hence, the new volume is:
[tex]V = \pi r^2 h \: \rm unit^3\\\\V = \pi (2r)^2 (2h)\: \rm unit^3\\\\V = 8\pi r^2 h \: \rm unit^3[/tex]
So, compared to the old volume, the new volume is increased eight-fold.
Therefore, the statement is false.

−4x+2y=−8
C
4x+2y=8
4x+2y=10
D
4x+2y=8
−4x−2y=−10
Answer: B.
[tex]4x - 2y = 8\\-4x + 2y = -8[/tex]
Step-by-step explanation:
Let's solve your system by elimination.
4x−2y=8;−2x+2y=6
Add these equations to eliminate y:
4x-2y=8
-2x+2y=6
2x=14
Substitute 7 for x in 4x−2y=8:
(4)(7)−2y=8
−2y+28=8 (Simplify both sides of the equation)
−2y+28+−28=8+−28 (Add -28 to both sides)
−2y=−20
−2y/−2=−20/−2 (Divide both sides by -2)
y=10
The probability of the number of defective circuit boards in a shipment is given in the tables for two different companies. Company A A 5-column table has 2 labeled rows. The first row is labeled Number defective (x) with entries 0, 1, 2, 3. The second row is labeled P (x i) with entries 0.21, 0.30, 0.41, 0.08. Company B A 5-column table has 2 labeled rows. The first row is labeled Number defective (x) with entries 0, 1, 2, 3. The second row is labeled P (x i) with entries 0.18, 0.32, 0.28, 0.22. What is the expected number of defective circuit boards for company A? What is the expected number of defective circuit boards for company B? Which company should be chosen for purchasing circuit boards? Explain.

The weighted average is a generalization of the expected value. The company that should be chosen for purchasing circuit boards is Company A.
What is the expected value?The weighted average is a generalization of the expected value. The expected value is the arithmetic mean of a large number of independently chosen random variable outcomes.
A.) The expected number of defective circuit boards for company A is,
Expected number = (0.21×0) + (0.30×1) + (0.41×2) + (0.08×3) = 1.36
B.) The expected number of defective circuit boards for company B is,
Expected number = (0.18×0) + (0.32×1) + (0.28×2) + (0.22×3) = 1.54
C.) Since the expected number of defective circuit boards for Company A is less, therefore, the company that should be chosen for purchasing circuit boards is Company A.

obtuse isosceles
Right isosceles
acute scalene
Answer:
obtuse isosceles
Step-by-step explanation:
An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. An equiangular triangle has three congruent angles.
