If ABC is congruent to DEC, angle B = 50 degrees and angle E = 5x x=

Answer: Nonlinear

Step-by-step explanation: If the exponent is to a power other than 1, it is nonlinnear.

The area of a circle, represented by the expression 3.14r², is a nonlinear function because the area changes in proportion to the square of the radius, demonstrating a quadratic change rather than a linear one.

The area of a circle is a function of the radius, represented by the expression 3.14r². This represents a nonlinear function because the area of the circle does not change at a constant rate with respect to the radius. Instead, the area changes in proportion to the square of the radius, which is a defining characteristic of a quadratic or second-degree polynomial function, not a linear one.

To further illustrate, let's consider a circle with a radius of 1 inch, which would have an area of approximately 3.14 square inches. If the radius is doubled to 2 inches, the area becomes approximately 4 times larger, not double, because the area is 3.14 * (2²) = 3.14 * 4 square inches. This quadratic change demonstrates the nonlinearity of the area function in relation to the radius.

Answer:

When two events X and Y are independent,

Then, P(X ∩ Y) = P(X) × P(Y)

We know that,

[tex]P(\frac{X}{Y})=\frac{P(X\cap Y)}{P(Y)}\text{ and }P(\frac{Y}{X})=\frac{P(X\cap Y)}{P(X)}[/tex]

Thus, by substituting the value of P(X ∩ Y),

[tex]P(\frac{X}{Y})=P(X)\text{ and }P(\frac{Y}{X})=P(Y)[/tex]

Which is the required condition for independent events.

In first option,

P(A)=0.3, P(B)=0.5, P(A|B)=0.15

[tex]\implies P(\frac{A}{B})\neq P(A)[/tex]

⇒ A and B are not independent events

In second option,

P(A)=0.2, P(B)=0.4, P(A|B)=0.2

[tex]P(\frac{A}{B})=P(A)[/tex]

⇒ A and B are independent events.

In third option,

P(A)=0.6, P(B)=0.2, P(A|B)=0.3

[tex]\implies P(\frac{A}{B})\neq P(A)[/tex]

⇒ A and B are not independent events

First Part: Not independent

Second Part: Independent

Third Part: Not independent

Two events A and B are independent if:

[tex]P(A|B)=P(A|B') \\Or,P(B|A)=P(B|A')[/tex]

Given,

[tex]P(A)=0.3, P(B)=0.5, P(A|B)=0.15[/tex]

[tex]P(A)=0.2, P(B)=0.4, P(A|B)=0.2[/tex]

[tex]P(A)=0.6, P(B)=0.2, P(A|B)=0.3[/tex]

[tex]P(A\cap B)=P(A|B)P(B)[/tex]

Then by substituting we get,

[tex]P(A|B)=P(A)[/tex] and [tex]P(B|A)=P(B)[/tex]

Computation of First probability:

So, if the probability is independent it will follow the above conditions.

[tex]P(A|B)=0.15\\P(A)=0.3\\0.3\neq 0.15\\ P(A|B)\neq P(A)[/tex]

So, it is not independent

Computation of second probability:

So, if the probability is independent it will follow the above conditions.[tex]P(A|B)=0.2\\P(A)=0.2\\0.2=0.2\\ P(A|B)= P(A)[/tex]

So, it is independent

Computation of second probability:

So, if the probability is independent it will follow the above conditions.

[tex]P(A|B)=0.3\\P(A)=0.6\\0.3\neq 0.6\\ P(A|B)\neq P(A)[/tex]

So, it is not independent.

Answer:

(x-1) x-12

Step-by-step explanation:

Step 1 :  Multiply first term of the first bracket to the first term of the other bracket

Step 2 :  Then multiply the first term of the first bracket to the last term of the second bracket.

Step 3 :  Now come to the second term of first bracket, multiply second term with first term of second bracket.

Step 4 :  Finally multiply last term of first bracket with the last term of the second bracket.

Step 5 :  Adding all the answers got from the steps, we get the final answer.

Final answer:

The FOIL method is an algebraic technique for multiplying two binomials, represented as (First, Outer, Inner, Last). For the expression (X+3)(x-4), we apply this method to get x^2 - x - 12 after combining like terms.

Explanation:

The FOIL method is a technique used in algebra to multiply two binomials. The acronym FOIL stands for First, Outer, Inner, Last and refers to the order in which you multiply the terms in the binomials. Applying the FOIL method to the expression (X+3)(x-4), we multiply the First terms (x × x), the Outer terms (x × -4), the Inner terms (3 × x), and the Last terms (3 × -4), then sum them all.

Step-by-step, this looks like:

First: x × x = x^2

Outer: x × (-4) = -4x

Inner: 3 × x = 3x

Last: 3 × (-4) = -12

Now, combine these results to get the final expression:

x^2 - 4x + 3x - 12

Combining like terms, we have:

x^2 - x - 12

Answer:

A. 33/56

Step-by-step explanation:

Make them have the same denominator of 56

so you get for the first one 49/56

the second one will be 16/56

subtract both and you get your answer of 33/56

Answer: A. 33/56

Step-by-step explanation:

To get the number of pages left, all we need to do is to subtract 2/7 from 7/8

number of pages left = 7/8 - 2/7

=49 - 16 / 56

= 33/56

Answer:

C x-3

Step-by-step explanation:

3 less than x - 49

Is means =

less than means -  (reversing the order)

x-3 = 49

Answer: C) x - 3 = 49

Step-by-step explanation: X represents the number that we are subtracting things from. 3 is how much (the number that we are) subtracting. 49 is the difference/answer. The problem is pretty much asking us to subtract 3 from x and get 49 as the answer. So, if you wrote that mathematically, the answer would be x - 3 = 49.

The Percentage of Sally's Team Wins :

[tex]\bf{\implies (\frac{Number\;of\;Games\;won\;by\;the\;Team}{Total\;Number\;of\;Games\;the\;Team\;Played}) \times 100}[/tex]

Given : Total Number of Games the Team Played = 25

Given : Number of Games won by the Team = 17

[tex]\bf{The\;Percentage\;of\;Team\;Wins = (\frac{17}{25}) \times 100}[/tex]

⇒ The Percentage of Sally's Team Wins = (17 × 4) = 68%

Sally's soccer team played 25 games and the team won 17 games. What percent of games did the team win?

The fraction [tex]\frac{17}{25}[/tex] represents the number of games that Sally's soccer team won out of all the games the team played.

To find what percent of games the team won, we can turn the fraction [tex]\frac{17}{25}[/tex] into a percent.

17 ÷ 25 = 0.68

0.68 × 100 = 68%

Therefore, Sally's soccer team won 68% of the games they played.

Answer:

option C (3, 2)

Step-by-step explanation:

We have to solve the system of equation by substitution method.

2x + y = 8 ------(1)

y = -x + 5 -------(2)

Now we substitute the value of y from equation (2) to equation (1)

2x + ( -x + 5) = 8

2x - x + 5 = 8

x + 5 = 8

x = 8 - 5

x = 3

Now from equation (2)

y = -x + 5

y = - 3 + 5

y = 2

Therefore, option C (3, 2) will be the answer.

Answer:

We will need 5 1/3 lbs  of hamburger

Step-by-step explanation:

We can use ratio's to solve this problem.  We will put breadcrumbs on top and hamburger on bottom.

1/4 c         1 1/3 c

--------- = -----------

1 lb             x lbs

Using cross products

1/4 *x = 1 * 1 1/3

1/4x = 1 1/3

Multiply each side by 4

4 * 1/4 x = 4 * (1 1/3)

x = 4 * 1 1/3

We need to convert 1 1/3 to an improper fraction

1 1/3 = (3*1+1)/3 = 4/3

x = 4 * 4/3

x = 16/3

Now we need to convert it back to a mixed number

3 goes into 16 5 times with 1 left over

x = 5 1/3 lbs

Answer:

360 screws

Step-by-step explanation:

First we need to determine how many screws she needs for the 2 decks

We will determine the number of screws for 1 deck

1 deck uses 25 pieces of wood

25 pieces of wood * 8 screws/ piece of wood = 200

200 screws per deck

She is building 2 decks

2 * 200 = 400

400 screws for the 2 decks

She has 40 screws

400 screws she needs - 40 screws she has = 360 screws she still needs
