Step-by-step explanation:

What is the probability that a customer ordered

a hot drink given that he or she ordered a large?

So we are looking for the percentage of a hot drink and a Large.

Our list:

Small

Medium Large

Hot

5

48

22

8

12

5

Cold

He can tell there is 10% atleast for hot and 0% for a large

The probability that a customer ordered a hot drink given that he or she ordered a large is 22%

Probability denotes the possibility of the outcome of any random event.

Given that a table of the first 100 customers' orders at a coffee shop.

We need to find the probability that a customer ordered a hot drink given that he or she ordered a large,

= 22 / 100

= 22%

Hence, the probability that a customer ordered a hot drink given that he or she ordered a large is 22%

Answer:

El cliente puede ordenar una comida en 60 formas distintas.

Step-by-step explanation:

El cliente escoge una entrada de las cinco opciones disponibles, luego un plato principal de cuatro opciones disponibles y un postre de tres opciones disponibles. Es costumbre consumir primero una entrada, después un plato principal y finalmente, un postre.

Estadísticamente hablando, se debe considerar un producto de tres combinaciones, puesto que el orden no importa a la hora de pedir, como sigue:

[tex]n = _{5}C_{1}\times _{4}C_{1}\times _{3}C_{1}[/tex] (1)

Donde:

[tex]n[/tex] - Total de combinaciones al ordenar una comida (entrada, plato principal, postre)

[tex]_{5}C_{1}[/tex] - Combinaciones posibles para pedir una entrada.

[tex]_{4}C_{1}[/tex] - Combinaciones posibles para pedir un plato principal.

[tex]_{3}C_{1}[/tex] - Combinaciones posibles para pedir un postre.

Ahora, desarrollamos la operación:

[tex]n = \frac{5!}{(5-1)!}\times \frac{4!}{(4-1)!} \times \frac{3!}{(3-1)!}[/tex]

[tex]n = 5\times 4\times 3[/tex]

[tex]n = 60[/tex]

El cliente puede ordenar una comida en 60 formas distintas.

Answer:

Step-by-step explanation:

Answer:

Original angle = 122*

Supplementary angle = 58*

Step-by-step explanation:

A supplementary angle is one of two angles that make up 180*

If one angle is 30*, its supplementary angle is 150*. 30 + 150 = 180.

So in this case we have two angles, the original and the supplementary angle. The original angle is 64* more than the supplementary angle. The key word is MORE.

The formula to figure it out would look like this:  x + (x + 64) = 180

x is the supplementary angle

x + 64 is the original angle (64 MORE than its supplementary angle)

180 is the total measure of the two angles because they are supplementary and we know that supplementary angles always equals 180* when added together.

Take the formula and do a little algebra.

x + (x + 64) = 180

Subtract 64 from both sides

x + x = 116

Combine the x's

2x = 116

Divide both side by 2

x = 58

Remeber we know that the original angle is 64 more than the supplementary angle, so we'll add the 64 to the value of x and we get 122.

x + 64 = 122

Check our work:

x + (x + 64) = 180

58 + 58 + 64 = 180

now the area of each tile is 24x36=864

now to find out how many tiles fit on the floor we need to do 86,400 divided by 864 which = 100

Answer: 18°

Step-by-step explanation:

Complementary angles are the angles that when we add them together, the value will equal 90°.

In this question, we've to add both angles and equate them to 90°. This will be:

(2x - 4) + (5x + 17) = 90

2x - 4 + 5x + 17 = 90

Collect like terms

2x + 5x = 90 + 4 - 17

7x = 77

x = 77/7

x = 11

Angle A will be:

= (2x-4)

= 2(11) - 4

= 22 - 4

= 18°

Answer:

Mean = 3.5

Step-by-step explanation:

The given data is :

4.5,5, 3.5, 2, 2.5

We need to find the mean of the given data.

We know that,

Mean = sum of observations/total no. of observations

Here,

Total no. of observations = 5

Sum of observations = 4.5 + 5+ 3.5+ 2+ 2.5 = 17.5

Mean,

[tex]m=\dfrac{17.5}{5}\\\\m=3.5[/tex]

Hence, the mean of the data set is equal to 3.5.

CP= Rs 400

loss%=12%

let sp be x

SP=CP-loss%*CP

x=400-12/100*400

x=40000-4800/100

x=35200/100

x=352

therefore sp =Rs 352

Answer:

S.P. = ₹352

Step-by-step explanation:

UNITARY METHOD:

If C.P. = ₹100

Then SP = ₹(100-12) = ₹88

If C.P. = ₹1

S.P. = ₹(88/100)

Then, as given: C.P. = Rs 400

S.P. = ₹( 88/100)*400

= ₹352

Therefore, S.P. = ₹352

Given: A triangular prism; 33 meters long, a base of 20 meters, a height of 24 meters. The other two sides of the triangle are each 26 meters

To find: What is the surface area of the triangular prism?

Formula: [tex]A = 12bh[/tex]

Solution: Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite each other. The formula is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.

Answer:

Step-by-step explanation:

A fraction consists of two parts the top number and the bottom one.

Think of the top number as the count and the bottom as the size indicator. So you have:

countsize indicator −−−−−−−−−−→proper names numeratordenominator

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Consider the action example of dividing 3 into 6.

We can do this division directly because their size indicators are the same. That is, we have: 61÷31. People do not normally write it this way but it is correct.

To directly divide the counts the size indicator must be the same

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So we need to see how many of 18 will fit into 34

We can not do this directly in one operation as the size indicators are not the same.

Lets make the size indicators (denominators) the same

Multiply by 1 and you do not change the value but

1 comes in many forms.

[34×1]÷18 → [34×22]÷18

[3×24×2]÷18 → 68÷18

Now that the size indicators (denominators) are the same we can just divide the counts (numerators)

countsize indicator→[68÷18]=6÷1=6

I could explain more showing the connection between this and the shortcut method but what I have shown you will do for now.

Answer:

The height of the arch at its center is 250/9 or about 27.78 feet.

Step-by-step explanation:

We can write an equation to model the parabolic arch.

Let the left-most point of the arch be the origin (0, 0).

Since the bridge has a span of 100 feet, the right-most point must be (0, 100).

We can use the factored form of a quadratic:

[tex]y=a(x-p)(x-q)[/tex]

Where p and q are the x-intercepts.

Our x-intercepts are x = 0 and x = 100. Hence:

[tex]y=ax(x-100)[/tex]

At a point 40 feet from the center, the height of the arch is 10 feet.

The center is x = 50. So, a point 40 feet from the center can be either x = 10 or x = 90.

So, for instance, when x = 10, y = 10. Substitute and solve for a:

[tex]10=10a(10-100)[/tex]

So:

[tex]\displaystyle a=-\frac{1}{90}[/tex]

The same value will result if we let x = 90 and y = 10.

Hence, our equation is:

[tex]\displaystyle y=-\frac{1}{90}x(x-100)[/tex]

The height of the arch at its center will be when x = 50. Hence:

[tex]y(50)=\displaystyle -\frac{1}{90}(50)((50)-100)=\frac{250}{9}\approx 27.78\text{ feet}[/tex]

Answer:

Ix + 2I - 5 = -(x - 1)*(x - 3)

Step-by-step explanation:

In the graph, we can see two functions a red one, f(x), and a blue one, g(x)

And the equation would be f(x) = g(x)

The red one is an absolute value function, we can see that the vertex is at x = -2 and at y = -5, and it has a slope equal to 1.

Remember that for an absolute value equation with a vertex (a, b) is:

f(x) = Ix - aI + b

Then in this case, the absolute value equation is:

f(x) = Ix - (-2)I - 5

f(x) = Ix + 2I - 5

The blue equation is a quadratic equation, with roots 1 and 3, and we can see that it opens down, so the leading coefficient is negative.

Remember that for a quadratic equation with roots a and b, with leading coefficient A is:

g(x) = A*(x - a)*(x - b)

Then in this case the quadratic equation is something like:

g(x) = -N*(x - 1)*(x - 3)

Then the equation will be something like:

f(x) = Ix + 2I - 5 = g(x) = -N*(x - 1)*(x - 3)

Ix + 2I - 5 = -N*(x - 1)*(x - 3)

The only option that has this shape is the first option (the top one) such that N = 1, then:

Ix + 2I - 5 = -(x - 1)*(x - 3)

is the correct option.

Answer: Linear

Step-by-step explanation: When determining whether the function table represents a linear or exponential relationship, we are checking to see if the rate of change is constant or increasing. If we look at the table, when x increases by 1, y increases by 3. This means that on that interval, the average rate of change is 3/1 = 3. When we increase x by 1 again, we see that y increases by 3 again. This means that the rate of change is constant for the function, so it must be linear.

Step-by-step explanation:

You pass 3x to the other side so you get 4y = -16 - 3x

to clear y you divide both sides by 4

y = (-16-3x )/ 4

you can simplify this so it so it gives us

y = -4 - 3/4x
