Step-by-step explanation

Answer:

Option A) 0.02

Step-by-step explanation:

The probability p that one of the questions is correct is

[tex]P = \frac{1}{4}[/tex]

The number of questions that will answer (number of trials) is [tex]n = 3[/tex].

We want to find out the probability that [tex]x = 3[/tex] three questions will be answered correctly.

To calculate this probability we use the binomial formula:

[tex]P(x) = \frac{n!}{x!(n-x)!} p^x(1-p)^{n-x}[/tex]

Where

[tex]x=3\\n=3\\p=0.25[/tex]

Then:

[tex]P(x=3) = \frac{3!}{3!(3-3)!} 0.25^3(1-0.25)^{3-3}[/tex]

[tex]P(3) =0.25^3[/tex]

[tex]P(3) = 0.0156[/tex]

P(3) = 0.0156≈0.02

The likelihood of an event stating the 30% chance of snow means that, in 100 identical weather circumstances, we would predict it to snow during 30. This does not deliver any information on the quantity of snow.

The likelihood of an event given its probability represents the chance of that event taking place. When we say that there is a 30% chance of snow tomorrow, this means that out of every 100 similar weather scenarios, we would expect it to snow in 30 of them. Hence, the likelihood of it snowing tomorrow is 30%. It's important to understand that probability is a way to quantify the uncertainty associated with events predicted to occur, based on the known conditions.

Regarding the example, if we know that 'If it snows more than three inches, the schools are mandated to close.' and we see that 'The schools closed.' we can infer that 'It snowed more than three inches.' This however has no direct relation to the probability of snow tomorrow.

[tex]2x+x+x+2y\times3y\times y\\\\=(2x+x+x)+(2y\times3y\times y)\\\\=4x+(2\times3)(y\times y\times y)\\\\=4x+6y^3[/tex]

Answer with step-by-step explanation:

We are given the following two functions:

[tex]s(x) = 3x - 6[/tex]

[tex]t(x) = 6 - 3x[/tex]

We are to find the simplified formula and domain for [tex] v ( x ) = \frac { s ( x ) } { t ( x ) } [/tex] and [tex] w ( x ) = \frac { t ( x ) } { s ( x ) } [/tex].

[tex]\frac{3x-6}{6-3x}=\frac{3(x-2)}{3(2-x)}=\frac{x-2}{2-x}=\frac{x-2}{-(x-2))}=-1 [/tex]

So the domain for this function is (-∞, +∞) for v(x) = -1.

[tex]\frac{6-3x}{3x-6}=\frac{3(2-x)}{3(x-2)}=\frac{2-x}{x-2}=\frac{2-x}{-(-x+2)}=\frac{2-x}{-(2-x)}=-1[/tex]

The domain of this function is (-∞, +∞) for w(x)= -1

ANSWER

v(x)=-1

Domain: (-∞,2)U(2,+∞)

EXPLANATION

We have the given function

s(x) = 3x - 6 and t(x) = 6 - 3x.

We want to find the simplified formula and domain for

[tex]v(x) =( \frac{s}{t} )(x)[/tex]

[tex]v(x) = \frac{s(x)}{t(x)} [/tex]

[tex]v(x) = \frac{3x - 6}{6 - 3x} [/tex]

This function is defined if and only if

[tex]6 - 3x \ne0[/tex]

[tex]x \ne2[/tex]

Hence the domain is:

[tex]x \ne2[/tex]

We now simplify to obtain;

[tex]v(x) = \frac{ - (6 - 3x )}{6 - 3x} = - 1[/tex]

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [4, 6 ]

f(b) = f(6) = 6² - 3(6) - 10 = 36 - 18 - 10 = 8

f(a) = f(4) = 4² - 3(4) - 10 = 16 - 12 - 10 = - 6

Multiply the side length by the number of sides to get the perimeter. The formula for finding the perimeter of a regular polygon is just the number of sides x the length of any side. Once you've multiplied those 2 numbers together, you've found the perimeter of the polygon

Final answer:

The perimeter of a polygon is calculated by adding together the lengths of all its sides. For regular polygons with equal side lengths, the perimeter is the side length multiplied by the number of sides. For irregular polygons, all unique side lengths must be measured and summed.

Explanation:

The perimeter of a polygon is the total length around the shape. It is calculated by summing the lengths of all its sides. For a regular polygon with all sides of equal length, like a square, if one side length is a, then the perimeter is simply 4a because there are four sides. In the case of irregular polygons, each individual side length must be measured and added together to find the total perimeter.

For instance, consider a rectangle with a length of l and a width of w; the perimeter would be 2l + 2w, because each opposite pair of sides are equal. The units used for the lengths will be the same units used for the perimeter, such as meters. Nonetheless, the calculation can become more complex with polygons of more sides. Each side must be accounted for precisely, and units must remain consistent.

Answer:

Final answer is [tex](4x^2+3)(x+2)[/tex].

Step-by-step explanation:

Given expression is [tex]4x^3+8x^2+3x+6[/tex].

Now we need to factor that by the method of grouping.

So make two groups having first two terms and then last two term.

Factor each group then factor once more.

[tex]=4x^2(x+2)+3(x+2)[/tex]

[tex]=(4x^2+3)(x+2)[/tex]

It can't be factored anymore so the final answer is [tex](4x^2+3)(x+2)[/tex].

the factored form of 4x^3+8x^2+3x+6 using the grouping method is (x+2)(4x^2+3).

To factor the polynomial 4x^3+8x^2+3x+6 using the grouping method, we can start by grouping terms in pairs and factoring out common factors in each pair. Here is a step-by-step explanation:

Therefore, the factored form of 4x^3+8x^2+3x+6 using the grouping method is (x+2)(4x^2+3).

we can think of this as the same as a deposit in a bank, so let's use the compound interest formula, since the book is increasing in value 12% per annum.

To convert 3.2 feet to inches, multiply by the conversion factor of 12 inches per foot. The calculation 3.2 feet x 12 inches/1 foot results in 38.4 inches.

To convert 3.2 feet to inches, we use the following ratio: 1 foot = 12 inches. This is a standard conversion factor between feet and inches in the customary system of measurements.

First, set up the conversion like this:

Multiply the number of feet by the unit equivalence.

3.2 feet x 12 inches/1 foot = x inches.

Perform the multiplication to solve for x.

3.2 x 12 = 38.4 inches.

Therefore, 3.2 feet is equivalent to 38.4 inches. Remember, when converting from a larger unit to a smaller unit like feet to inches, you need to multiply by the conversion factor.

Answer:

So we can write an equation to solve this:

And then we are going to solve for x

x(12/100) = 36

36 x (100/12) = 300

The total number of candy bars was 300

Jillian sold 12% of the class's candy bars, which amounts to 36 bars. To find the total, calculate what 1% would be by dividing 36 by 12, and then multiply by 100 to find that the class sold 300 candy bars in total.

The student is asking about a practical application of percentages in a real-world context, which is a common subject in middle school mathematics. To find the total number of candy bars sold by the class, we need to use the information that Jillian sold 12% of the total and that this amounted to 36 candy bars. The calculation is straightforward: if 12% equals 36, we want to find 100% (the total).

To do this, we set up a simple proportion: if 12% is 36, then 1% would be 36 divided by 12, which is 3 candy bars. Since we're looking for the total, we multiply the number of candy bars representing 1% (which is 3) by 100 to find that the class sold a total of 300 candy bars before taxes.

Step-by-Step Calculation:

Find 1% of the total by dividing 36 candy bars by 12%.

1% of the total = 36 candy bars / 12 = 3 candy bars.

Multiply the value of 1% by 100 to find the total amount.

Total candy bars = 3 candy bars × 100 = 300 candy bars.

Using the Pythagorean Theorem, you should get 45 [9 + 36]. Then, take the square root of 45 and simplify it to 3√5.

The correct choice is D.

Answer:

option A) yes, measure of interior angle is 90

Step-by-step explanation:

Tessellation:

the tiling of an flat surface or plane by one or more geometric surfaces is tessellation. No overlapping or gap or un-evenness is left during tessellation, all the shapes fit perfect to the plane or flat surface. There are three geometric shapes that can be used for tessellation.

These shapes are:

Square

Triangle

Hexagon

As in given problem the polygon given is square

So YES the tessellation of plan is possible and the as the interior angle of square is 90 degrees so

option A is correct complete answer i.e. yes, measure of interior angle is 90 !

Answer:

upper left

Step-by-step explanation:

The generic equation for a circle centered at (h, k) with radius r is ...

(x -h)^2 +(y -k)^2 = r^2

Comparing that equation to the one you have, you can see that ...

-h = 0

-k = +3

r^2 = 9

Then you have (h, k) = (0, -3) and a radius of 3.

The circle has its center on the y-axis 3 units below the x-axis and just touches the x-axis. This is a description of the graph at upper left.

In solving the inequality, 3x+8/x-4 <= 0, we identify critical points and assign intervals based on them. The solution offers two possible scenarios: x is less than or equal to -8/3 or x is greater than 4.

The inequality 3x+8/x-4 =< 0 can be divided into two possible scenarios by clarifying the critical points. To solve this inequality, you first need to identify where the expression equals zero, that's where 3x+8=0 and x=4. Solving 3x+8=0 yields x=-8/3, which is the first

possible solution. Another critical point is where the denominator is zero, which is x=4.

Next, we need to check the signs of these intervals: (-inf, -8/3), (-8/3, 4) and (4, inf). Testing these intervals on the given inequality gives us the

solution that x is less than or equal to -8/3 or x is greater than 4 . Remember, x cannot be equal to 4 because it makes denominator zero in the origin expression which is undefined in mathematics.

Therefore, the correct solution is 'x less than or equal to -8/3 or x greater than 4'.

Triangle 2

Step-by-step explanation:

To determine which triangle has the bigger area, we would need to figure our the area of the triangles.

To solve for the area of the triangles, we would use the formula length × width × height or l × w × h

They gave us the information to the triangles in the question, so we would just solve.

Triangle 1: [tex]300 *400*500= 60,000,000[/tex]

Triangle 2: [tex]300*400*700=84,000,000[/tex]

When you finish solving, you would see that triangle 2 has the bigger area.

Triangle 2 would be the CORRECT answer because it has a bigger area than Triangle 1.
