Set (X, Y) Unif([0, 1] x [-1,0]). This means that (X, Y) is a uniform random point on the rectangular [0, 1] x [-1,0] then X and Y are independent.

Since the area of this region is 1, we have:

f(X,Y) = 1

Now we need to find the marginal PDFs of X and Y. In order to find fX(X), we integrate f(X,Y) over all possible values of Y:

fX(X) = ∫ f(X,Y) dy

= ∫ 1 dy (since f(X,Y) = 1)

= 1

Similarly, to find f_Y(Y), we integrate f(X,Y) over all possible values of X:

f_Y(Y) = ∫ f(X,Y) dx

= ∫ 1 dx (since f(X,Y) = 1)

= 1

Therefore, we have: f(X,Y) = fX(X) * fY(Y) which shows that X and Y are independent.

Answer:

x = 15p

-75

Explanation:

remove brackets:

4px + 4 = 64

solving for x --> 4px = 64 - 4 then--> 4px = 60

then diving both sides by 4p --> x = 60\4p --> x = 15p

now solving for x when p is -5

we will substitute the -5 in the equation we got --> x= 15 (-5)

which will give us --> x = -75

Answer:

-6

Step-by-step explanation:

using the rules of exponents

• \(a^{-m}\) = \(\frac{1}{a^{m} }\)

• \(a^{\frac{1}{2} }\) = \(\sqrt{a}\)

then

- 18 × \(9^{-\frac{1}{2} }\)

=-  18 × \(\frac{1}{9^{\frac{1}{2} } }\)

= - 18 × \(\frac{1}{\sqrt{9} }\)

= - 18 × \(\frac{1}{3}\)

= -6

Answer: The answer should be -6

Step-by-step explanation:

18(9^−1/2)

= −18(9^−1/2)

= (−18)(0.333333)

= −6

So, what you want to do is first solve 9^-1/2, it will come out to be about 0.333333

You are going to put 0.333333 in for 9^-12 and then multiply:

-18(9^-1/2) = (-18)(0.333333)

(-18)(0.333333) = -6

The time taken to travel the distance 70 Km/h is 11 hours.

Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took.

The formula can be rearranged in three ways:

Given:

time = 9 hours

speed = 85 Km/h

Now, distance

=speed * time

=85 * 9

= 765 km

As, the speed is 70 km/h

time = distance/ speed

time = 765 / 70

time = 10.92

time= 11 hours

Hence, the time taken to travel the distance 70 Km/h is 11 hours.

Brandon has 239 quarters and 49 dimes.

Assume that the number of quarters as q and the number of dimes as d.

If each quarter is worth $0.25 and each dime is worth $0.10, then the total value of the quarters and dimes is $64.65:

0.25q + 0.10d = 64.65                      (1)

Also given that the number of quarters is 6 less than five times the number of dimes, that is,

q = 5d - 6                     (2)

Put the value of q from the equation (2) to equation (1),

0.25(5d - 6) + 0.10d = 64.65

1.25d - 1.50 + 0.10d = 64.65

1.35d - 1.50 = 64.65

Answer:

9 comedy

12 horror

Step-by-step explanation:

First, there are 360 degrees in a circle.

Comedy = 90 degrees

Action and romance = 90 degrees combined

Horror = 120 degree

Science fiction = 60 degrees

To find sci fi : 90 +90 +120 = 300 - 360 = 60 degrees

36 students took the survey.

1/4 × 36 = 9

Horror is 120 degrees out of 360 degrees or 1/3 of the circle.

1/3 × 36 = 12

Answer: 12 students

Step-by-step explanation:

360* circle, 1 student per 10* so 120* = 12 students.

To double check, 90* = 9 students.

The area of the wrapping paper would be = 72.5in².

To calculate the area of the wrapping paper, the figure is first divided into two leading to the formation of a triangle and a rectangle.

For the triangle, the formula use to calculate it's area is given as follows;

Area = 1/2 base × height

base = 15-10 = 5 in

height = 9-4 = 5 in

area = 1/2×5 × 5

= 25/2 = 12.5 in²

Area of a rectangle = length× width

width = 4 in

length = 15 in

area = 4×15 = 60in²

Answer:

Step-by-step explanation:

left side:   5 - 4 + 7x + 1 = 1 + 7x + 1 = 7x + 2

No solution is when we have the same number of x-es and different sums of other numbers on both sides of equation. So we have to put 7 next to x and any numer except 2 at the second place.

So the right side could be 7x+1 or 7x+3 or 7x+125 and so on.

One solution is when we have different number of x-es on both sides of equation. The sums of other numbers could be any numbers.

So the right side could be ex.: 2x+1, x+2, 8x, 3x+(-18), and so on.

Infinitely many solutions is when we have  the same number of x-es and the same sums of other numbers on both sides of equation. So we have to put 7  next to x and numer 2 at the second place.

So the right side has to be 7x + 2

(a) A basis for the solution space of the homogeneous system of linear equations is:

{(-3, 1, 0, 0), (-5, 0, -5, 1)}

(b) The dimension of the solution space is 2.

To find a basis for the solution space, we first write the augmented matrix of the system and row-reduce it to its echelon form or reduced row-echelon form.

Then, we identify the free variables (variables that can take any value) and express the dependent variables in terms of the free variables. The basis for the solution space consists of the vectors corresponding to the free variables.

In this case, after performing row operations, we obtain the reduced row-echelon form:

[1 0 -1 -1 0]

[0 1 3 2 0]

[0 0 0 0 0]

The first and second columns correspond to the free variables x3 and x4, respectively. Setting these variables to arbitrary values, we can express x1 and x2 in terms of x3 and x4 as follows: x1 = -x3 - x4 and x2 = -3x3 - 2x4. Therefore, a basis for the solution space is {(-3, 1, 0, 0), (-5, 0, -5, 1)}.

Since the basis has 2 vectors, the dimension of the solution space is 2.

Answer:

the simplified expression for 2x + 1/3 + 4x - 2/2 is 6x - 2/3.

Step-by-step explanation:

To solve the expression 2x + 1/3 + 4x - 2/2, we need to combine like terms and simplify the expression.

First, let's combine the terms with the same variable, which are 2x and 4x:

2x + 4x = 6x

Next, let's simplify the fractions. We need to find a common denominator for 1/3 and 2/2, which is 6. We'll rewrite the fractions with the common denominator:

1/3 = 2/6

2/2 = 6/6

Now, let's rewrite the expression with the combined terms and simplified fractions:

6x + 2/6 - 6/6

Next, subtract the fractions with the same denominator:

6x + (2/6 - 6/6)

The numerator of the first fraction (2/6) needs to be subtracted from the numerator of the second fraction (6/6). This gives us:

6x + (-4/6)

Simplify the fraction:

6x - 4/6

Now, we can simplify further by dividing both the numerator and denominator of the fraction by their greatest common divisor, which is 2:

6x - 2/3

Therefore, the simplified expression for 2x + 1/3 + 4x - 2/2 is 6x - 2/3.

Any non-empty subset of Rⁿ, where any linear combination of vectors in S is again a vector in S, is a subspace of Rⁿ.

Given that S is a non-empty subset of Rⁿ such that any linear combination of vectors in S is again a vector in S. Therefore, to prove that S is a subspace of Rⁿ, we have to show that S satisfies three conditions. These conditions are as follows;

The condition for being a subspace of Rⁿ

Firstly, a subspace must be closed under addition. In other words, if x and y are any two vectors in S, then their sum x + y must be in S.

Secondly, a subspace must be closed under scalar multiplication. In other words, if x is any vector in S and c is any scalar, then cx must be in S.

Finally, a subspace must contain the zero vector, denoted by 0.S is a subspace of Rⁿ

From the conditions mentioned above, we can show that S is indeed a subspace of Rⁿ, since S satisfies all the required conditions.

Therefore, we can say that any non-empty subset of Rⁿ, where any linear combination of vectors in S is again a vector in S, is a subspace of Rⁿ.

The present price of a motorcycle is Rs. 225000.

And the depreciation rate = 8% = 0.08.

Therefore, the numbers of years after which the price of motorcycle be Rs 175204.58 is gievn by

⇒ 175204.58  = 225000(1 - 0.08)^x

⇒ 175204.58/225000 = (1 - 0.08)^x

⇒ 0.78 = (1 -0.08)^x

⇒ 0.78 = 0.92^x

⇒ -0.107 = xlog(0.92)

⇒ -0.107 = x(-0.036)

To determine the truth value of the statement (p V-9) A r using the conditions provided, we can substitute the given truth values for p, q, and r into the statement.

a) p is false, q is true, and r is true:
(p V-9) A r = (false V-9) A true
= (-9) A true
= true

Therefore, the truth value of (p V-9) A r is true when p is false, q is true, and r is true.

b) p is true, q is false, and r is true:
(p V-9) A r = (true V-9) A true

Therefore, the truth value of (p V-9) A r is also true when p is true, q is false, and r is true.
