Let's say we have a box with 6 marbles: 3 red, 1 blue, 1 green, and 1 yellow. What is the probability of picking a yellow marble, returning it to the box, and then picking a blue marble?
A) 1/12
B)1/30
C)1/36
D)1/11

Answer:

Difference = 36

Step-by-step explanation:

Given that,

The boiling point of Oxygen = -183

The melting point of Oxygen = -219

We need to find the temperature difference of the melting point and the boiling point.

Difference = boiling point - melting point

= -183-(-219)

= -183+219

= 36

Hence, the required temperature difference is 36.

Answer:

25 in

Step-by-step explanation:

Hypotenuse is the longest side in the right angle triangle. It is proven by the fact that the square of hypotenus is the sum of the squares of the two other sides.    

The hypotenuse of the Pythagorean triple 25 in, 15 in, 20 in is 25 in

The Pythagoras theorem is used to find the sides of a right angle triangle. The formula below is used to find the sides of a right angle triangle(Pythagoras's theorem) is represented below

where

c = hypotenuse

a and b are either opposite or adjacent sides

A right angle triangle is a triangle that has one of its angles as 90°.

A right angle triangle has the following sides :

The longest side of a right angle triangle is the hypotenuse. Base on the Pythagorean triple, the hypotenuse is 25 inches because its the longest side.

Answer:

x = 3, x = 11

Step-by-step explanation:

Since PR is an angle bisector then it divides the opposite side into segments which are proportional to the other 2 sides, that is

[tex]\frac{PQ}{PS}[/tex] = [tex]\frac{QR}{SR}[/tex] , substitute values

[tex]\frac{x+1}{16}[/tex] = [tex]\frac{x-2}{x+1}[/tex] ( cross- multiply )

(x + 1)(x + 1) = 16(x - 2) ← expand left side using FOIL

x² + 2x + 1 = 16x - 32 ( subtract 16x - 32 from both sides )

x² - 14x + 33 = 0 ← in standard form

(x - 3)(x - 11) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 11 = 0 ⇒ x = 11

============================================

Explanation:

For situation A,

The pairing (x,y) tells us what a certain student likes in terms of color.

For example, the point (Allen, Red) tells us that Allen likes the color red. We could also have (Allen, Green) telling us he also likes green. Because the input "Allen" maps to more than one output, this means situation A is not a function. A function is only possible if any given input maps to exactly to one output. The input must be in the domain. The domain in this case is the set of all students in the classroom.

In contrast, Situation B is a function because a student will only have one favorite math teacher. I'm interpreting this to mean "number one favorite" and not a situation where a student can select multiple favorites.

Answer:

Step-by-step explanation:

1 yard is about 36 inches.

A square yard in square inches will therefore be:

= 36 * 36

= 1,296 inch²

He needs 497 square inches of gray fabric. In square yards that will be:

= 497/1,296

= 0.38 yard² of gray material

He needs 746 square inches of yellow:

= 746/1,296

= 0.58 yard² of yellow.

Answer:

27

Step-by-step explanation:

In this case, because we have a polynomial where all x-values exist, we can plug the value (x=2) straight into the function:

[tex]\lim_{x \to \ 2} (2x^3+x^2+7)[/tex]

[tex]= 2(2)^3+(2)^2+7[/tex]

[tex]= 2(8)+4+7[/tex]

[tex]= 27[/tex]

The limit of (2x^3+x^2+7) as x approaches 2 equals 27, which makes sense since the value of (2x^3+x^2+7) at x = 2 is 27.
