Answer:

Yes.

Step-by-step explanation:

Let's say a=22 and b=-5

According to the Commutative Property of Multiplication, a*b=b*a. Hence, 22*(-5)=(-5)*22.

Answer:

The range = 14

Step-by-step explanation:

Definition: (range of a data set)

the range of a data set is the difference between the greatest and smallest  value.

In a box plot :

We should notice the maximum (generally located at the top right) and the minimum value (generally located at the top left)

Then we make the difference.

97.

In our case :

Max value = 24

Min value = 10

Therefore

The range = 24 - 10 = 14

The volumes of the cylinder are 565. 56 cubic inches and  1131. 12 cubic inches respectively.

The formula for volume of a cylinder is expressed as;

Volume = πr²h

Where;

Substitute the values

Volume = 3. 142 × 6² × 5

Volume = 3. 142 × 36 × 5

Volume = 565. 56 cubic inches

If the height is doubled, h = 2 × 5 = 10

Substitute the values

Volume = 3. 142 × 6² × 10

Volume = 3. 142 × 36 × 10

Volume = 1131. 12 cubic inches

Thus, the volumes of the cylinder are 565. 56 cubic inches and  1131. 12 cubic inches respectively.

The function is a continuous random variable. The correct option is B.

Continuous random variables are those that have a large number of uncountable possible values. There are countless possible values. In this illustration, there is no limit to the range of possible values for the height of a giraffe in meters, such as 10.5m, 15.22m, 12.0m, etc. There are countless options.

Discrete Variables that have a finite number of possible outcomes are known as random variables. When a dice is rolled, for example, the outcomes could be 1, 2, 3, 4, 5, or 6. There are only six possible values, with nothing in between.

Therefore, the function is a continuous random variable. The correct option is B.

Answer:

a) 18

b)248

c) 58

Step-by-step explanation:

The formula is:

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1)d

[tex]a_{n}[/tex]  Is the number at the n term

[tex]a_{1}[/tex] Is the first number in the sequence

n Is the number for the term

d is the common difference.  How much is added each time in the sequence.  In this case, 2.5

Put in the numbers that you know and solve for the unknown.

A:

[tex]a_{8}[/tex] = 0.5 + (8 -1)(2.5)

[tex]a_{8}[/tex]  = 0.5 +(7)(2.5)

[tex]a_{8}[/tex] = 0.5 + 17.5

[tex]a_{8}[/tex] = 18

B:

We follow the same pattern, but we are now looking for [tex]a_{100}[/tex].

[tex]a_{100}[/tex] = 0.5 + (100-1)(2.5)

[tex]a_{100}[/tex] = 0.5 + 247.5

[tex]a_{100}[/tex] = 248

C:

This time we know the value of the number in the sequence, we do not know which term it is.

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n - 1)d  Put in what we know

148 = 0.5 + (n -1)2.5  Distribute the 2.5

148 = 0.5 + 2.5n - 2.5  Combine like terms

148 = 3 + 2.5n  Subtract 3 from both sides of the equation

145 = 2.5n  Divide both sides by 2.5

58 = n

Step-by-step explanation:

In this equation, given

f(x) = 3x + 9 and g(x) = 5x -1

So the question is what is the value of f if we put the value of g(x) in f(x)

So to solve the equation we need to replace the value of x in f(x) with g(x)

So it was obtained as below

f(g(x)) = 3(5x-1) + 9

= (15 x - 3) + 9

= 15 x + 6

A linear recurrence relation is a function or sequence in which each term is a linear combination of the terms that came before it.

The recurrence relation exists [tex]$T(n)=\Theta\left(3^n\right)$[/tex].

Recurrence relations are used to simplify complex problems by reducing them to an iterative process based on simpler versions of the problem.

Using the substitution method, we find out that

[tex]T(n) &=n+3 T(n-1) \\[/tex]

[tex]&=n+3(n-1)+3^2 T(n-2) \\[/tex]

[tex]&=n+3(n-1)+3^2(n-2)+3^3 T(n-3) \\[/tex]

[tex]&=\cdots \\[/tex]

[tex]&=n+3(n-1)+3^2(n-2)+\cdots+3^{n-1}(n-(n-1))+3^n T(0) \\[/tex]

simplifying the above equation, we get

[tex]$&=\frac{3^{n+1}-2 n-3}{4}+3^n T(0) \\[/tex]

[tex]&=\Theta\left(3^n\right)[/tex]

Even without doing the full calculation it is not hard to check that [tex]$T(n) \geq 3^{n-1}+3^n T(0)$[/tex], and so [tex]$T(n)=\Omega\left(3^n\right)$[/tex].

A cheap way to obtain the corresponding upper bound is by considering

[tex]$S(n)=T(n) / 3^n$[/tex], which satisfies the recurrence relation  

[tex]$S(n)=S(n-1)+n / 3^n$[/tex].

Repeated substitution then gives

[tex]$\frac{T(n)}{3^n}=\sum_{m=1}^n \frac{m}{3^m}+T(0)[/tex]

Since the infinite series [tex]$\sum_{m=1}^{\infty} \frac{m}{3^m}$[/tex] converges, this implies that [tex]$\frac{T(n)}{3^n}=\Theta(1)$[/tex] and so [tex]$T(n)=\Theta\left(3^n\right)$[/tex]

Therefore, the recurrence relation exists [tex]$T(n)=\Theta\left(3^n\right)$[/tex].

Step-by-step explanation:

an equation must and always have an equal sign(=) otherwise it is an expression e.g. 2x-3y or x-2

an equation will look like this: a=b or other equations

∫dF=F(x,y)=12ax2+bxy+12ℓy2+c=0 is the exact ode.

Specifically, an exact equation is a differential equation that can be solved instantly without the aid of any specialized methods. If the result of a straightforward differentiation, a first-order differential equation (of one variable) is referred to as an exact differential or exact differential. The equation

P(x, y)dy/dx + Q(x, y) = 0,

or in the equivalent alternate notation

P(x, y)dy + Q(x, y)dx = 0,

is exact if

∂P(x, y)/∂x =  ∂Q(x, y)/∂y

In this instance, a function R(x, y) will exist whose partial x-derivative is Q and partial y-derivative is P, and whose equation R(x, y) = c (where c is constant) will implicitly establish a function y that will satisfy the initial differential equation.

An exact ODE is one where the equation can be written as  dF=0  for some  F(x,y). Expanding using chain rule, this means an equation of the form

∂1Fdx+∂2Fdy=0

Now if the second partials of  F  exist and are continuous, they must be equal due to Clairaut. So, given an equation

Mdx+Ndy=0

if we have

∂2M=∂1N

then there is an  F  such that

M=∂1F, N=∂2F

and hence that equation is exact, and the solution is simply

∫dF=0

We have

M=ax+by⇒∂2M=b

N=kx+ℓy⇒∂1N=k

so to be exact, we must have that  b=k .

Then, integrating  M  and  N , we have

F(x,y)=∫Mdx=12ax2+bxy+g(y)

F(x,y)=∫Ndy=bxy+12ℓy2+h(x)

and comparing these two, we can see that

∫dF=F(x,y)=12ax2+bxy+12ℓy2+c=0

is a solution to the equation for any  a,b,c,ℓ . You can solve for  y  by quadratic methods.

The surface area of a cuboid is given by:

Surface area = 2xy + 2xz + 2yz

Here length = x = 7 inches

Breadth = y = 3 inches

Height = z = 8 inches.

Substituting the values in the formula, we get that:

Surface area = A = 2(7)(3) + 2(7)(8) + 2(3)(8) inches²

A = 42 + 112 + 48 inches²

A = 42 + 160 inches²

A = 202 inches²
