Answer:Cubic polynomials are polynomials of degree three. Examples include \begin{align*}x^3+8, x^3-4x^2+3x-5\end{align*}, and so on. Notice in these examples, the largest exponent for the variable is three (3). They are all cubics

Let x1 = 12, y1 = 15, and y2 = 3. Let y vary inversely with x. Find x2.

vladimir1956 [14]

Answer:

x2 = 60

Step-by-step explanation:

If the variables x and y are inversely proportional, the product x * y is a constant.

So using x1 and y1 we can find the value of this constant:

$x1 * y1 = k$

$12 * 15 = k$

$k = 180$

Now, we can use the same constant to find x2:

$x2 * y2 = k$

$x2 * 3 = 180$

$x2 = 180 / 3 = 60$

So the value of x2 is 60.

The number of minutes that Samantha waits to catch the bus is uniformly distributed between 0 and 15 minutes. What is the probab

Drupady [299]

Using the uniform distribution, it is found that there is a 0.3 = 30% probability that Samantha has to wait less than 4.5 minutes to catch the bus.

<h3>What is the uniform probability distribution?</h3>

It is a distribution with two bounds, a and b, in which each outcome is equally as likely.

The probability of finding a value of at lower than x is:

$P(X < x) = \frac{x - a}{b - a}$

In this problem, the time is uniformly distributed between 0 and 15 minutes, hence the bounds are a = 0 and b = 15.

The probability that Samantha has to wait less than 4.5 minutes to catch the bus is given by:

$P(X < 4.5) = \frac{4.5 - 0}{15 - 0} = 0.3$

Find the dimensions of an open rectangular box with a square base that holds 2000 cubic cm and is constructed with the least bui

Vesnalui [34]

<h3>The dimensions of the given rectangular box are:</h3><h3>L = 15.874 cm , B = 15.874 cm , H = 7.8937 cm</h3>

Step-by-step explanation:

Let us assume that the dimension of the square base = S x S

Let us assume the height of the rectangular base = H

So, the total area of the open rectangular box

= Area of the base + 4 x ( Area of the adjacent faces)

= S x S + 4 ( S x H) = S² + 4 SH ..... (1)

Also, Area of the box = S x S x H = S²H

⇒ S²H = 2000

$\implies H = \frac{2000}{S^2}$

Substituting the value of H in (1), we get:

$A = S^2 + 4 SH = S^2 + 4 S(\frac{2000}{S^2}) = S^2 + (\frac{8000}{S})\\\implies A = S^2 + (\frac{8000}{S})$

Now, to minimize the area put :

$(\frac{dA}{dS} ) = 0 \implies 2S - \frac{8000}{S^2} = 0\\\implies S^3 = 4000\\\implies S = 15.874 \approx 16 cm$

Putting the value of S = 15.874 cm in the value of H , we get:

$\implies H = \frac{2000}{S^2} = \frac{2000}{(15.874)^2} = 7.8937 cm$

Hence, the dimensions of the given rectangular box are:

L = 15.874 cm

B = 15.874 cm

H = 7.8937 cm

A basket of laundry is being separated. Divide 48 pieces of clothing into 2 groups so that the ratio is 1:3

Alla [95]

Ratio is 1:3.....added = 4

1/4(48) = 48/4 = 12
3/4(48) = 144/4 = 36

the 2 groups will be 12 and 36
