Answer:

4/7

Step-by-step explanation:

The conditional probability of A and B happening : P(AnB) is 1/6, and the conditional probability of B happening : P(B) is 7/24, the probability of A happening is 1/6 : 7/24 = 4/7

P(A/B) = Given that B occurs, find the probability of A occuring

Answer:

56/100 or 0.56

Step-by-step explanation:

you first need the dinominators to be the same so to figure that at you can do 100 divided by 10 which is 10. so to make the doniomators even you need to multipy the 2/10 by 10. so 2x10=20 and 10x10=100 so that makes the fraction 20/100. now you have 20/100 + 36/100 =? which makes it a lot easier. so now all you do is add ONLY THE NUMERATOR so you do 20+36 which is 56 and you keep the 100 and that 56/100.

To make it into a decimal, this one is easy because the denominater is 100 so you just take 56.0 and move the decimal two place values so its 0.56. :)

The volume of a box is the amount of space in the box

The dimensions that minimize the cost of the box is 4 in by 4 in  by 4 in

The dimensions of the box are:

Width = x

Depth = y

So, the volume (V) is:

[tex]V = x^2y[/tex]

The volume is given as 64 cubic inches.

So, we have:

[tex]x^2y = 64[/tex]

Make y the subject

[tex]y = \frac{64}{x^2}[/tex]

The surface area of the box is calculated as:

[tex]A =x^2 + 4xy[/tex]

The cost is:

[tex]C = 2x^2 + 4xy[/tex] --- the base is twice as expensive as the sides

Substitute [tex]y = \frac{64}{x^2}[/tex]

[tex]C = 2x^2 + 4x * \frac{64}{x^2}[/tex]

[tex]C =2x^2 + \frac{256}{x}[/tex]

Differentiate

[tex]C' =4x - \frac{256}{x^2}[/tex]

Set to 0

[tex]4x - \frac{256}{x^2} = 0[/tex]

Multiply through by x^2

[tex]4x^3 - 256= 0[/tex]

Divide through by 4

[tex]x^3 - 64= 0[/tex]

Add 64 to both sides

[tex]x^3 = 64[/tex]

Take the cube roots of both sides

[tex]x = 4[/tex]

Recall that:

[tex]y = \frac{64}{x^2}[/tex]

So, we have:

[tex]y = \frac{64}{4^2}[/tex]

[tex]y = 4[/tex]

Hence, the dimensions that minimize the cost of the box is 4 in by 4 in  by 4 in

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Answer:

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion. In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.
