5. Si usted juega a piedra, papel y tijera, sabiendo que Piedra gana a tijera, la tijera gana al papel y el papel gana a la piedra, ¿Cuál es la probabilidad de que usted gane?

Answer: Slope is 4/3

Step-by-step explanation:  slope is change of y / change of x

k = Δy/Δx = (7-11) /(2-5) = -4 / -3 =  4/3

Answer:

a) 22 batches

c) 7.3 batches

Step-by-step explanation:

a) It takes 0.25 cup of sugar to make a batch of chocolate chip cookies. I have 5.50 cups of sugar. How many batches of cookies can I make?

0.25 cup = 1 batch

5.5 cup = x

Cross Multiply

0.25 cup × x = 5.5 cup × 1 batch

x = 5.5 cup × 1 batch/0.25 cup

x = 22

I can make 22 batches of chocolate chip cookies. You may use the scratchpad to show your work.

(b) Lemon Cookies It takes 0.75 cups of sugar to make a batch of lemon cookies. I have 5.5 cups of sugar. How many batches can I make?

0.75 cup = 1 batch

5.5 cup = x

Cross Multiply

0.75 cup × x = 5.5 cup × 1 batch

x = 5.5 cup × 1 batch/0.75 cup

x = 7.3 batches

I can make 7.3 batches of lemon cookies. You may use the scratchpad to show your work.

Answer:

[tex]Domain = (-\infty, \infty)[/tex]

[tex]Range = (-\infty, 4][/tex]

Increasing interval is: [tex](-\infty, 0)[/tex]

Decreasing interval is: [tex](0, \infty)[/tex]

Constant at no interval

Step-by-step explanation:

Given

See attachment for graph

Solving (a): The domain

From, the attached graph, we have:

[tex]y = -x^2 + 4[/tex]

The degree of the polynomial (i.e 2) is even.

Hence, the domain is the set of all real numbers, i.e.

[tex]Domain = (-\infty, \infty)[/tex]

Solving (b): The range

The curve of [tex]y = -x^2 + 4[/tex] opens downward, and the maximum is:

[tex]y_{max} = 4[/tex]

This means that the minimum is:

[tex]y_{mi n} = -\infty[/tex]

Hence, the range of the set is:

[tex]Range = (-\infty, 4][/tex]

Solving (c): Interval where the function increases/decreases/constant

In (a), we have:

[tex]Domain = (-\infty, \infty)[/tex]

Split to 2 (at vertex x = 0)

[tex](-\infty, 0)[/tex] and [tex](0, \infty)[/tex]

So:

The increasing interval is: [tex](-\infty, 0)[/tex]

The decreasing interval is: [tex](0, \infty)[/tex]

The function has a tangent at [tex]x = 0[/tex] but at no interval, was the function constant

Answer:

a reflection across line m

Step-by-step explanation:

A reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K". Option B is correct.

Reflection is defined in an atmosphere as when the beam of light or wave strikes to the plane or curved surface deviates back from the atmosphere.

The final transformation is to determine that transition states have been shown in the image that describes how pre-image GHJK transformed to image G'H"J"K".

Steps of Transformation

Pre-image GHJK first rotates anticlockwise by an angle of 90° to G'H'J'K'.

Then G'H'J'K' reflected across the line m to G'H"J"K". It is the final transition state.

Thus, a reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K".

#SPJ2

Explanation:

Both figures shown in A and B are triangular pyramids. The base is a triangle, and the lateral sides are also triangles. Another example would be rectangular pyramids where the base is a rectangle, and the lateral sides are triangles.

Choice C is ruled out because cones aren't considered pyramids.

Choice D is a combination of a rectangular prism, and a rectangular pyramid stacked on top, so it's not purely a pyramid only. We can rule out choice D.

Answer:

Geometric sequence.

Step-by-step explanation:

Simply defined, a complex sequence is a set of numbers in a sequence, whose numbers include imaginary numbers. In essensce, not all numbers in a complex sequence are real numbers.

A geometric sequence is a sequence in which each number must be multiplied by a number (referred to as the common ratio) to attain the next value in the sequence.

An arithmetic sequence is a sequence of numbers in which one has to add a value to the previous number to attain the next number.

A simple sequence can be defined as a pattern of numbers, such as a list of multiples.

In the given sequecne:

3, 9, 27, 81, 243

One can see that each element is three times the last. Diving any two consecutive elements (elements next to each other) will result in the numerical value of (3). Therefore this is a geometric sequence since it fits all of the criteria of a geometric sequence and even has a common ratio of (3).

Answer:

D - 192

Step-by-step explanation:

So the solve this, lets use the formula for area of a triangle:

b*h / 2 = A

b is the base, h is the height.

In this case, our base is 32, and our height is unknown.

To find it we must use pythagreons theorm:

[tex]a^2+b^2=C^2[/tex]

a is half of the base in this case, since tecnically this iscoceles traingle(2 same sides) cut in half is 2 right triangles.

32/2 = 16

b is the unknown, and C is the hypotenuse(longest length) which is 20:

[tex]16^2+b^2=20^2[/tex]

[tex]256*b^2=400[/tex]

[tex]b^2=144[/tex]

[tex]b=12[/tex]

So we know b, whihc is our height, is 12.

Plugging this in:

32*12 / 2 = A

384 / 2 = A

192 = A

So the area of the triangle is 192.

Hope this helps!

Answer:

D: 192 square ft

Step-by-step explanation:

We are given all 3 side lengths of the triangle, and we notice that 2 of the sides are congruent (the 2 sides that are 20 ft). Therefore, we can safley say that this triangle is isosceles. What this tells us is that the height bisects the base. This is important because we can say that the base for each of the right triangles created by the height is 16. From there, we can say that h = 12 because 20 and 16 are basically 4 and 5 multiplied by 4, which means that the side lengths form a scaled-up version of the Pythagorean Triple 3-4-5. Now, just calculate the area by doing [tex]\frac{1}{2}*32*12[/tex] (basically just half * base * height), which gives us 192 [tex]ft^{2}[/tex]. Hope this helps!

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

Explanation:

If the circumference is r = 12 cm, then the diameter is double that at d = 2*r = 2*12 = 24 cm.

This then leads to the circumference of C = pi*d = pi*24 = 24pi

This is exact in terms of pi. Replace pi with something like 3.14 to find its approximate value. The circumference is the distance around the circle's edge, aka perimeter.

Answer:

[tex]{ \bf{y = mx + c}} \\ 2 = ( - 2 \times - 1) + c \\ c = 0 \\ \\ { \boxed{ \bf{y = - 2x}}}[/tex]

Answer:

y = -2x

Step-by-step explanation:

The equation of a line in slope intercept form

y = mx+b  where m is the slope and b is the y intercept

y = -2x +b

Using the point

2 = -2(-1)+b

2 = 2+b

Add -2 to each side

2-2 =b

0=b

y = -2x+0

y = -2x

Answer:

7  10  13   16

Step-by-step explanation:

a1 = 4

a6 = 19

n = 6

d = ?

a6  = a1 + (n - 1)d        

19 = 4 + (6 - 1)*d

19 - 4 = 5*d

15 = 5d

d = 15/5

d = 3

Step-by-step explanation:

To find the slope, we use the slope formula

m = ( y2-y1)/(x2-x1)

= ( 8-2)/(9-6)

 =6/3

  =2

Answer: The slope of the linear function is 2.

Step-by-step explanation:

We can use the formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] to find the slope

[tex]\frac{8-2}{9-6} \\\frac{6}{3} \\2[/tex]

The slope is 2.

Answer:

every parallelogram is a square? False

every rectangle with four congruent sides is a square? True

every rectangle is a quadrilateral? True

every quadrilateral is a rectangle?​ False

Step-by-step explanation:

every parallelogram is a square?

A parallelogram has two opposite pairs of parallel lines and opposite congruent sides. A square needs to have 4 right angles and all sides need to be equal. In the restrictions of a parallelogram, these cannot be concluded, therefore parallelogram are not always squares.

every rectangle with four congruent sides is a square?

Square require 4 congruent sides and 4 right angles. Rectangles already have  4 right angles. If you add 4 congruent sides to the mix, it means that these rectangles are always squares.

every rectangle is a quadrilateral?

A quadrilateral is defined by a shape having 4 sides. Rectangles have 4 sides, so they fit into the category of quadrilaterals.

every quadrilateral is a rectangle?​

A quadrilateral is a just a shape with four sides. We do not know if it has 4 right angles, so not every quadrilateral is a rectangle.
