Answer: 6x^2 - 9x + 3

Step-by-step explanation:

first, i multiplied the parentheses.

3x x 2x - 3x - 3 x 2x - 3 x (-1)

then, i calculated/multiplied it.

6x^2 - 3x - 6x + 3

finally, i collected the like terms.

6x^2 - 9x + 3

Step-by-step explanation:

You plug in x values to get the y values are dot-in the points!

y = -x^2

You plug in -2 and get -(2)^2 = -(4) = -4

Same thing with all other values.

Step-by-step explanation:

Assuming that Y1 and Y2 are independent exponential random variable with mean 3

where : U = Y1 + Y2 applying the property of exponential distribution sum of exponentials will follow a gamma distribution

i.e. ∝ = 2 , and β = 1

note : U = 2X

Hence probability distribution function X =

Fx (x) = p( X ≤ x )

= p( U ≤ 2x )

= Fu (2x)

probability density function  X

f (x) = [tex]\frac{dF(2x)}{dx}[/tex]  = 2 Fu (2x)

attached below is the remaining part of the solution

In this exercise we have to use probability knowledge to calculate the density of the function, so we have to:

[tex]f(u) \left \{ {{ue^u: u>0} \atop {0}} \right.[/tex]

[tex]f(x) \left \{ {{4xe^{-2x}: x>0} \atop {0}} \right.[/tex]

Assuming that [tex]Y_1[/tex] and [tex]Y_2[/tex] are independent exponential random variable where:

[tex]U = Y_1 + Y_2[/tex]

Applying the property of exponential distribution sum of exponentials will follow a gamma distribution, we have:

Hence probability distribution function X , will be:

[tex]F_x (x) = p( X \leq x )\\= p( U \leq 2x )\\= F_u (2x)[/tex]

So we can say that:  

[tex]f (x) = \frac{dF}{du} = 2 F_u (2x)[/tex]

Answer:

"The diagonals of the door frame are congruent."

Step-by-step explanation:

The statement that would not give enough information would be "The diagonals of the door frame are congruent." This is because a rectangle does have congruent diagonals but a rhomboid also has congruent angles and has opposing parallel sides. Therefore, this statement does not give sufficient information to prove that the object in question is a rectangle. We would need more information such as the length of the sides or the degree of the angles.

Answer:

16.

Step-by-step explanation:

We need 8 + a number to equal 24. We need it to equal 24 because 2 + 4 = 6 and 6 x 4 = 24. To find the missing number we need to subtract 8 from 24. 24 - 8 = 16. Let's plug 16 into the equation.

8 + 16 = 4(2 + 4)

24 = 4(2 + 4)

24 = 4(6)

24 = 24

Therefore, 16 is the correct answer.

Answer:

c

Step-by-step explanation:

18x³y⁴ = 2 * 3 * 3 * x³ * y⁴

24x²y⁵ = 2 * 2 * 2 * 3 * x² * y⁵

GCF = 2 * 3 * x² * y⁴ = 6x²y⁴

18x³y⁴ + 24x²y⁵ = 6x²y⁴(3x  + 4y)

Answer:The answer would be x^4 -16

Explanation: use the FOIL method.

(x^2 +4)(x^2 -4)= x^4 +4x -4x -16. 4x and -4x cancel each other out. You are left with x^4 -16.

Step-by-step explanation:

From the given information:

The mean [tex]\hat x = \dfrac{\sum x}{n}[/tex]

[tex]\hat x = \dfrac{25+36+41+28+29+32+29+37+34+34+37+35+30+36+31+31}{16}[/tex]

[tex]\overline{x} = \dfrac{535}{16}[/tex]

[tex]\overline{x} = 33.44[/tex]

The sample variance is as follows:

[tex]S^2 = \dfrac{\sum dx^2 - ( \dfrac{\sum dx)^2}{n} )}{n-1}[/tex]

[tex]S^2 = \dfrac{279- ( \dfrac{7}{15} )^2}{15}[/tex]

[tex]S^2 = 18.585[/tex]

Answer:

1 x 4 x 12 = 48

Step-by-step explanation:

48 subs

The number of subscribers at 12 weeks is required.

Number of subscribers at 12 weeks would be 1048576.

a = Initial subscriber count at 2 weeks = 1

Week at which number of subscribers is required is 12.

x = Duration between the weeks = [tex]12-2=10[/tex]

r = Rate of increase = 4

The required formula is

[tex]f(x)=ar^x\\\Rightarrow f(10)=1(4)^{10}\\\Rightarrow f(10)=1048576[/tex]

Number of subscribers at 12 weeks would be 1048576.

Answer:

[tex]|A| = - 28[/tex]

Step-by-step explanation:

Given

[tex]A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right][/tex]

Required

Determine the determinant

For a two by two matrix, A such that:

[tex]A = \left[\begin{array}{cc}a&b\\c&d\end{array}\right][/tex]

The determinant |A| is:

[tex]|A| = a * d - b * c[/tex]

So, in

[tex]A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right][/tex]

The determinant is:

[tex]|A| = -2 * 5 - 6 * 3[/tex]

[tex]|A| = -10 - 18[/tex]

[tex]|A| = - 28[/tex]

Answer:

A c must not be finite.

A ∪ B must be infinite.

A ∩ B must not be infinite.

Step-by-step explanation:

Must A c be finite?

Suppose

U = {....-4,-3,-2,-1,0,1,2,3,4.......}

A = {....-4,-2,0,2,4.......} which is infinite set

B = {....-3,-1,0,1,3.......} which is also infinite set

So We need to calculate the A compliment

[tex]A^{c}[/tex] = U - A = {....-4,-3,-2,-1,0,1,2,3,4.......} - {....-4,-2,0,2,4.......} = {....-3,-1,0,1,3.......}

Hence [tex]A^{c}[/tex] is also an infinite set.

The statement "Must A c be finite?" is incorrect.

Must A ∪ B be infinite?

In AUB all the elements of set A and set B are combined into a single set to get the union of A and B. If A and B are the infinite set then their union must also be an infinite set because all the elements of infinite sets will be there so the union of these infinite sets will also be an infinite set.

The Statement "Must A ∪ B be infinite?" is correct.

Must A ∩ B be infinite?

In A∩B the common elements of both sets will be the answer to the intersection of A and B set. If we consider the A and B are the infinite subsets of a Universal set that carry all the elements then there will not be any common element in both sets A and B.

The Answer of A∩B is { } or empty set.

The statement "Must A ∩ B be infinite? " is incorrect.

Option A

Step by step explanation :-

Distance between Springfield to Longmeadow is 3.8 km.

Adamsville to Springfield is 7.6 km.

Answer:

1. B. <1 and <2

2. C. 37°

3. B. 40°

Step-by-step explanation:

1. Complementary angles add up to 90°.

From the diagram given, <1 and <2 are complementary because they sum up to 90°.

The answer is B. <1 and <2

2. Given that,

m<1 = 37°, m<4 = 37° also.

This is because m<1 and m<4 are Vertical angles. Vertical angles pair are equal.

The answer is: C. 37°

3. If m<1 = 50°, then:

m<5 = 90 - m<4

m<1 = m<4 = 50° (vertical angles)

m<5 = 90 - 50 (substitution)

m<5 = 40°

Answer is B. 40°
