if 13 cards are randomly selected from a standard 52-card deck, must at least 2 be of the same denomination (2, 3, 4, , j, q, k, a)? why? (select all that apply.)

Answer:

28

Step-by-step explanation:

Since 42 tomatoes were picked, we can take the reciprocal (the reversed fraction) of the 9:6 ratio and make it 6:9, then multiply 42 by 6/9.

The number of students which received a result of less than 60 is 42 if  the result of a fictional stat 100 final exam taken by 120 students, as given in the following relative frequency distribution.

Given:

we have grade and cumulative frequency table.

The acquired data are arranged in tables using the frequency distribution method. The information may include test scores, local weather information, volleyball match results, student grades, and so forth. To facilitate understanding, data must be presented meaningfully after collection. Set up the data so that a table contains a summary of all of its characteristics. Frequency distribution is what we call this.

we are asked to find the number of students which received a result of less than 60 = ?

The frequency for the grade less than 60 is:

60 : 15%+20%

= 35%

now calculate the percentage:

35% × 120

35/100 × 120

= 7×6

= 42

Hence 42 students received less than 60.

Probability that a flood of the same size will occur in the following year = [tex]\frac{1}{50}[/tex]

What is probability?

Probability gives us the information about how likely an event is going to occur

Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.

Probality of any event is greater than or equal to zero and less than or equal to 1.

Probability of sure event is 1 and probability of unsure event is 0.

The cost of constructing the box will be = $81.77

Since the question gives us information about the rectangle,

so the area of the rectangle is shown by,

Area = 2 x (length + width)

So we have the area as,

Area = 2(lh + wh) +lw

(since the area per square meter is also given so we added l x w)

Since the cost of the base is = $5 per square meter and the cost of the sides is = $3 per square meter, so area in terms of the cost function,

⇒ C = 3 x 2(lh + wh) + 5 x l x w

⇒ C = 6(lh + wh) +5lw ---------equation 1

According to the question, the length of the rectangular container is twice that of the width of the container,

⇒ l = 2w

Substituting the new value of l in equation 1,

⇒ C = 6(2wh + wh) + 10 [tex]w^{2}[/tex]

⇒ C = 18wh + 10 [tex]w^{2}[/tex] ---------- equation 2

To calculate the volume of the rectangle,

V = length x width x height ( lwh )

substituting v = 10 and 2w = l,

2[tex]w^{2}[/tex]h = 10

h = [tex]\frac{5}{w^{2} }[/tex]

Substitute the value of h in equation 2,

⇒ C = 18w x [tex]\frac{5}{w^{2} }[/tex] + 10[tex]w^{2}[/tex]

⇒ C = [tex]\frac{90}{w}[/tex] + 10[tex]w^{2}[/tex] --------- equation 3

Differentiating the above equation we get,

⇒ C* = - [tex]\frac{90}{w^{2} }[/tex] + 20w

⇒ 20w = [tex]\frac{90}{w^{2} }[/tex]

Multiply both sides by [tex]w^{3}[/tex]

⇒ [tex]20w^{3}[/tex] = 90

⇒ [tex]w^{3}[/tex] = 4.5

w = 1.65

Put the value of w in equation 3,

⇒ C = [tex]\frac{90}{1.65}[/tex] + 10 x [tex]1.65^{2}[/tex]

⇒ C = 81.77

The value of their vertical distance at a horizontal distance of 6 feet is 2 feet

From the question, we have the following parameters that can be used in our computation:

The equation of the function: y = -1/3x + 4

The above equation is a linear function

A linear function is represented as

y = mx + c

Where

slope = m and y-intercept = c

From the question, we have

x-axis = ground distance

y-axis = one of the poles

When the horizontal change is 6 feet, it means that

x = 6

So, we have

y = -1/3 x 6 + 4

Evaluate the products

y = -2 + 4

Evaluate the sum

y = 2

Graph the line [tex]y=-x+10[/tex] with a dotted boundary and shade the region above the line.

Check whether a polynomial function is an odd-degree or even-degree function, as well as whether the leading coefficient is positive or negative, before attempting to determine its end behavior.

Given,

The polynomial end behavior;-

The behavior of the function graph at the "ends" of the x-axis is known as the end behavior of a function, or f. In other words, if we look at the right end of the x-axis (as x approaches +) and the left end of the x-axis (as x approaches ), the end behavior of a function represents the trend of the graph.

Here,

Look at the polynomial function's leading term to identify its end behavior. The leading term will dominate the graph since it has the largest power and will thus increase much more quickly than the other terms as x gets very large or very small.

That is,

Check the function's odd- or even-degree status and the leading coefficient's positive or negative value before attempting to forecast the polynomial function's end behavior.

The congruence theorem that will prove △BDA and △DBC is A. Hypotenuse-leg (HL) congruence.

Determining the right congruence theorem that will prove △BDA and △DBC after being provided a schematic of two right triangles.

Since we are aware that the hypotenuse-leg theorem stipulates that if the hypotenuse and one of the right triangles' legs are congruent with their equivalent hypotenuses in other right triangles, the triangles are said to be congruent.

We can see from our diagram that hypotenuse(AB) of △BDA equals to hypotenuse (CD) of △DBC.  

We can see that triangles BDA and DBC share a common side DB.

Using Pythagorean theorem we will get

CD² = DB²+BC²

AB = DB²+AD²

given that CD=AB, Upon using this information we will get,

DB²+BC² = DB²+AD²

subtracting DB² from both sides of our equation we will get,

BC² = AD²

Cutting squares on both sides

BC = AD

Hence, by HL congruence △BDA ≅ △DBC.

True, When the demand is greater than the capacity, impossible situations can arise.

Demand is outlined as the quantity of a good that buyers are willing and able to purchase at a specific price. This is an if...then statement, thus if the price is $1,000, the quantity demanded is 60, and so on. Therefore, it is a function with the form y = f(x), where x now represents price and y represents quantity.

A linear demand equation is defined as Q = a - bP in standard form. In other words, pricing influences the quantity demanded. The price equation, often known as the inverse demand equation or price equation, treats the price as a function f of the amount demanded: P = f. (Q). Simply solve for P from the demand equation to obtain the inverse demand equation.

So, the answer is true that when the demand is greater than the capacity, impossible situations can arise.

The 100 feet per second rate at which rocket is rising vertically upwards and the 50 feet distance of the observation position from the launch, indicates;

A) The height of the rocket after exactly 2 seconds is 200 feet

B) The rate of the angular motion at which to scan upwards to keep track of the rocket is 2/17 radians per second

Angular motion is a circular motion of an object about a fixed axis, described in radians per second.

The rate at which the rocket is rising up in the air = 100 feet per second

The horizontal distance from the point of launch to the observer = 50 feet

The time at which the height of the rocket is required = 2 seconds

A) The height of the rocket after 2 seconds, h = 2 s × 100 ft/s = 200 ft

B) The angle of elevation of the line of sight to the rocket = θ

tan(θ) = h/50

sec²(θ)·(dθ/dt) = (1/50)·(dh/dt)

(dθ/dt) = (1/50) × (dh/dt)/sec²(θ)  = (1/50)×(dh/dt)×(cos²(θ))

At time, t = 2 seconds, the height of the rocket = 200 feet

Therefore;

tan(θ) = 200/50 = 4

θ = arctan(4)
