Hey There!

To find the area of a regular hexagon we use the formula

\(A = \frac{1}{2} ap\)

a = apothem

p = perimeter

to find the peremeter we multiply the side length by the number of sides

which is 6

6x6=36 so the perimeter is 36

now we just plug it into the area of a hexagon formula

36x5.2=187.2

\(\frac{187}{2} =93.6\)

so the area is 93.6 cm ³

Answer:

20

Step-by-step explanation:

The theoretical probability of drawing 2 red marbles from the bag with replacement is one-fifth, which means that the probability of drawing 2 red marbles in any one trial is 1/5 or 0.2.

The number of times Jonah is expected to select 2 red marbles in 100 trials can be predicted using the expected value formula:

Expected value = (Number of trials) x (Probability of success in one trial)

Expected value = 100 x 0.2

Expected value = 20

Therefore, a reasonable prediction of the number of times Jonah will select 2 red marbles in 100 trials is 20. Therefore, the answer is 20.

What is a quadratic equation?

A second-order polynomial equation with a single variable, x, is known as a quadratic equation.

i.e. \(ax^{2} +bx+c=0\)

Let '\(x\)' be a number, then

The six-times a number= \(6x\)

&, the square of a number= \(x^{2}\)

Now, according to the question,

or,  \(6x = x^{2} -7\)

or, \(x^{2} -6x-7=0\)

or, \(x^{2} -7x+x-7=0\)

or, \(x(x -7)+1(x-7)=0\)

The probability values are obtained as -

P(X + Y > 3) = 0.45

P(XY = 2) = 0.10

P(XY > 1) = 0.55

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

The joint probability mass function XX and YY is given as -

p(1,1)=0.45p(2,1)=0.05p(3,1)=0.05p(1,2)=0.05p(2,2)=0.1p(3,2)=0.1p(1,3)=0.05p(2,3)=0.05p(3,3)=0.1p(1,1)=0.45p(1,2)=0.05p(1,3)=0.05p(2,1)=0.05p(2,2)=0.1p(2,3)=0.05p(3,1)=0.05p(3,2)=0.1p(3,3)=0.1.

The first operation is -

P(X + Y > 3)

Substitute the values in the equation -

P(X + Y > 3) = P(3,1) + P(2,2) + P(3,2) + P(1,3) + P(2,3) + P(3,3)

P(X + Y > 3) = 0.05 + 0.1 + 0.1 + 0.05 + 0.05 + 0.1

P(X + Y > 3) = 0.45

Therefore, the value is obtained as 0.45.

The second operation is -

P(XY = 2)

Substitute the values in the equation -

P(XY = 2) = P(2,1) + P(1,2)

P(XY = 2) = 0.05 + 0.05

P(XY = 2) = 0.10

Therefore, the value is obtained as 0.10.

The third operation is -

P(XY > 1)

Substitute the values in the equation -

P(XY > 1) = 1 - [P(XY ≤ 1)]

P(XY > 1) = 1 - [P(1,1)]

P(XY > 1) = 1 - 0.45

P(XY > 1) = 0.55

Therefore, the value is obtained as 0.55.

The system has an infinite number of solutions, but the only solution is (a, b) = (0, 0).

The given system of equations can be solved using the substitution method. We can begin by solving the first equation,\(a^2 + b^2\), for either a or b. Let's solve for a:

\(a^2 + b^2 = 0\)

\(a^2 + b^2 = 0\)

\(a^2 = -b^2\)

\(a = \pm\sqrt(-b^2)\)

We can substitute this expression for a into the second equation, \(3a^2 - 2ab - b^2 = 0\), and simplify:

\(3(\pm\sqrt(-b^2))^2 - 2(\pm\sqrt(-b^2))b - b^2 = 0\)

\(3b^2 - 2b^2 - b^2 = 0\)

0 = 0

Since 0 = 0, this means that the system of equations has an infinite number of solutions. In other words, any values of a and b that satisfy the equation \(a^2 + b^2 = 0\) will also satisfy the equation \(3a^2 - 2ab - b^2 = 0\)

However, the equation \(a^2 + b^2 = 0\) only has a single solution, which is a = b = 0. Therefore, the solution to the system of equations is (a, b) = (0, 0).

Answer: Half of them are even and half of them are odd.

Step-by-step explanation:

The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.

The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.

Therefore, out of the given numbers, half of them are even and half of them are odd.

Answer:

a. 0.63

b. 0.33

Step-by-step explanation:

Here is a probability question. When two events are independent, it means that the probability of one of the events happening has no effect on the probability on the other happening.

From the question, let P(H) be the probability of passing the history course while P(E) is the probability of passing the English course;

By representation;

P(H) = 0.75

P(E) = 0.84

a) Probability of passing both

This means that he passes history and also passes English;

Mathematically that would be represented as;

P(E) * P(H) = 0.84 * 0.75 = 0.63

b) Probability that he passes exactly one of the courses.

This means that he passes one and he fails the other. Mathematically, we should remember that the probability of an event not happening = 1 - probability of the event happening

Let P’(H) and P’(E) be the probability of failing the history and english courses respectively;

Thus; P’(H) = 1 - 0.75 = 0.25

while P’(E) = 1-0.84 = 0.16

Now the probability that he passes exactly one means he passes one and fails the other.

So in this case, we have two scenarios; He passes History and fail English or passes English and fails history.

Thus, we have;

[P(H) and P’(E) or P(E) and P’(H)]

In probability, and means multiplication while or means addition; thus we have;

{P(H) * P’(E) } + {P’(H) * P(E)}

= ( 0.75 * 0.16) + (0.25 * 0.84)

= 0.12 + 0.21 = 0.33

Step-by-step explanation:

the domain is (-7, 1]

the range is (2, 7]

So the correct option is the third one.

For a given function we identify the domain as the set of the inputs of the function, in this case, represented by the horizontal axis, while the range is the set of the outputs of the function, in this case, represented by the vertical axis.

So, to identify the domain of the function, we just need to find the smallest and largest x-values graphed, these are:

x = -7

x = 1

Then the domain is (-7, 1]

(the parenthesis is because the point (-7, 1) is in an open circle, which means that it does not belong to the graph).

For the range we can do the same thing, but on the vertical axis, the smallest and largest values are:

y = 2

y = 7

So the range is (2, 7]

Then the correct option is the third one.

Answer:

  the correct choice is marked

Step-by-step explanation:

The process for completing the square would generally put x-terms on one side of the equal sign and the constant term on the other side:

  x^2 +4x = 3

Then the square of half the x-coefficient would be added to both sides. Here, that is (4/2)^2 = 4.

  x^2 +4x +4 = 7

In order to make this match one of the answer choices, we must multiply both sides by 4.

  4x^2 +16x +16 = 28

Now, we can factor the left side to see a match to the last answer choice.

  (2x +4)^2 = 28

As you can see, we had to deviate from the "complete the square" process to arrive at an equation that matches an answer choice. It cannot be said that the chosen equation "is used in the process." It might be useful to discuss this question with your teacher.
