Step-by-step explanation:

Answer:

(2,4)

Step-by-step explanation:

substitute the [tex]y = 2x[/tex] for the [tex]y[/tex] in [tex]x = -y + 6[/tex]

[tex]x = -(2x) + 6[/tex]

[tex]x = -2x + 6[/tex]

[tex]3x = 6[/tex]

[tex]x = 2[/tex]

next take [tex]x = 2[/tex] and input it into [tex]y = 2x[/tex]

[tex]y = 2(2)[/tex]

[tex]y = 4[/tex]

so if [tex]x =2[/tex] and [tex]y = 4[/tex], the ordered pair solution is:

[tex](2,4)[/tex]

Answer:

1.8 meters

Step-by-step explanation:

7.2÷4= 1.8

Answer:

1.8 m

Step-by-step explanation:

let side be 'a'.

perimiter of a square = 4(a)

7.2 = 4(a)

7.2/4 = a

therefore, a = 1.8 m.

Answer:

4

Step-by-step explanation:

M,q 14,4

The value of q in the system of equations 2m-5q=8 and 4m+2q=64 is 4 thus option (A) is correct.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

As per the given system of equations,

2m-5q=8

4m+2q=64

Multiply by 2 into the equation 2m - 5q = 8

4m - 10q = 16

Subtract 4m - 10q = 16 by 4m+2q=64

-10 - 2q = 16 - 64

-12q = -48

q = 4

Hence"The value of q in the system of equations 2m-5q=8 and 4m+2q=64 is 4".

Step-by-step explanation:

Well, we can use simple subtraction to answer this problem. You have 10 cookies, and you give away 2, you need to subtract 10 cookies by 2:

10 - 2 = 8

Therefore, you will have 8 cookies left.

Answer:

Step-by-step explanation:

The best way to gather this information is to create a survey that asks all the pertinent information regarding organic food and surveying a large population of the individuals that enter her store. This selected population would need to be selected at random so that the sample group accurately represents the choices of the entire population of customers. Otherwise, the data would be biased and not valid.

Solution :

We have to prove that [tex]$\overline{A \cup B} = \overline{A} \cap \overline{B}$[/tex]   (De-Morgan's law)

Let  [tex]$x \in \bar{A} \cap \bar{B}, $[/tex] then [tex]$x \in \bar{A}$[/tex] and [tex]$x \in \bar{B} $[/tex]

and so [tex]$x \notin \bar{A}$[/tex] and [tex]$x \notin \bar{B} $[/tex].

Thus, [tex]$x \notin A \cup B$[/tex] and so [tex]$x \in \overline{A \cup B}$[/tex]

Hence, [tex]$\bar{A} \cap \bar{B} \subset \overline{A \cup B}$[/tex]   .........(1)

Now we will show that [tex]$\overline{A \cup B} \subset \overline{A} \cap \overline{B}$[/tex]

Let [tex]$x \in \overline{A \cup B}$[/tex] ⇒ [tex]$x \notin A \cup B$[/tex]

Thus x is present neither in the set A nor in the set B, so by definition of the union of the sets, by definition of the complement.

[tex]$x \in \overline{A}$[/tex] and  [tex]$x \in \overline{B}$[/tex]

Therefore, [tex]$x \in \overline{A} \cap \overline{B}$[/tex] and we have [tex]$\overline{A \cup B} \subset \overline{A} \cap \overline{B}$[/tex]  .............(2)

From (1) and (2),

[tex]$\overline{A \cup B} = \overline{A} \cap \overline{B}$[/tex]

Hence proved.

True

Even though it landed on heads 8/10 times, ther's still a 50% chance that it will land on tails. It doesn't change the percentage of it landing on either side. So in that case, it is true.

Hope this helps!

The statement, A coin is flipped 10 times and lands on heads 8 times. The theoretical probability that the next coin flip will be heads is 50% is True.

The probability of an occurrence is a figure that represents how likely it is that the event will take place. In terms of percentage notation, it is expressed as a number between 0 and 1, or between 0% and 100%.

here, we have,

we know that,

The higher the likelihood, the more likely it is that the event will take place. A definite occurrence has a chance of 1 while an impossible event has a probability of 0.

we have,

When a coin is flipped the probability of getting a heads and a tail is 50%.

Hence, without the consideration of the flips and the result the theoretical probability that the next coin flip will be heads is 50%.

The statement, A coin is flipped 10 times and lands on heads 8 times. The theoretical probability that the next coin flip will be heads is 50% is True.

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

22+15x−11=0

Step 1: Simplify both sides of the equation.

22+15x−11=0

22+15x+−11=0

(15x)+(22+−11)=0(Combine Like Terms)

15x+11=0

15x+11=0

Step 2: Subtract 11 from both sides.

15x+11−11=0−11

15x=−11

Step 3: Divide both sides by 15.

Answer:

7 inches and 5 inches

Step-by-step explanation:

The length the length and width of the rectangle be l and b.

Accodrding to question,

Width, b = l-2

Perimeter, P = 24 inches

We know that,

The perimeter of a rectangle is given by :

P = 2(l+b)

24 = 2(l+l-2)

12 = 2l-2

14=2l

l = 7 inches

Width, b = 7-2 = 5 inches

Hence, the length and width of the rectangle are 7 inches and 5 inches respectively.

Answer:

Length = 6 inches

No
