One cubic foot of a crushed mineral weighs 150 pounds. How many pounds of the crushed mineral can a container with the dimensions shown hold?

Answer:

9/13

Step-by-step explanation:

P(odd or less than 5) = number of odd cards + number of cards less than 5 / total number of cards

P(odd or less than 5) = (20 + 16) / 52

P(odd or less than 5) = 36 / 52

P(odd or less than 5) = 9 / 13

Therefore, the probability of picking an odd card or a card less than 5.

Answer is 9/13

Therefore , the solution of the given problem of probability comes out to be  z-score from a typical normal distribution.

Any considerations technique's fundamental objective is to determine the likelihood that a claim is true or that a particular incident will take place. Any number range from one to one, when 0 traditionally signifies a percentage and 1 typically implies the degree of certainty, can be used to represent chance. A probability illustration shows the likelihood that a particular event will occur.

Here,

The formula for the standard error of the mean (SEM), which is as follows:

=> SEM = the standard deviation / √(sample size).

We can enter these numbers into the SEM calculation to determine the SEM given that the standard deviation of the tariff rates is $1200 and the sample size is 400:

=> SEM=$1200/√(400)

=> $1200/20 =$60

It is possible to calculate the z-score for a $80 departure from the mean with a $60 SEM as follows:

=>  z = (80 - 0) / $60 = 1.3333

Now that we have the probability corresponding to the z-score of 1.3333,

we can look up the cumulative distribution function (CDF) of the standard normal distribution using a z-table or a statistical calculator.

The CDF depicts the likelihood that a random variable will occur is less than or equal to a certain z-score from a typical normal distribution.

The two solutions to the simultaneous equations are; y1 = -0.87  and y2 = 2.87. x1 = 2.87, x2 =  -0.87

To solve these simultaneous equations, we can use the method of substitution. We can rearrange the second equation to isolate one of the variables, for example, y:

y = 2 - x

Now, substitute this expression for y into the first equation:

x^2 + (2 - x)^2 = 9

Expand the equation:

x^2 + (4 - 4x + x^2) = 9

Combine like terms:

2x^2 - 4x + 4 = 9

Move all terms to one side to set the equation to equal zero:

2x^2 - 4x - 5 = 0

Now, we can solve this quadratic equation using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

In our equation, a = 2, b = -4, and c = -5:

x = (4 ± √((-4)^2 - 4(2)(-5))) / (2 x 2)

x = (4 ± √(16 + 40)) / 4

x = (4 ± √56) / 4

The two possible values for x are:

x1 ≈ (4 + 7.48) / 4 = 2.87

x2 ≈ (4 - 7.48) / 4 = -0.87

Now, we'll find the corresponding y values using the equation y = 2 - x:

For x1 ≈ 2.87:

y1 ≈ 2 - 2.87 ≈ -0.87

For x2 ≈ -0.87:

y2 ≈ 2 - (-0.87) ≈ 2.87

So, the two solutions to the simultaneous equations are approximately (2.87, -0.87) and (-0.87, 2.87), both correct to 2 decimal places.

The value of D represents the vertical displacement or shift of the basic cosine graph. Therefore, the vertical displacement of the given graph is pi - 3.

What is Displacement?

In physics, displacement refers to the distance and direction of an object's change in position from its starting point. It is a vector quantity that measures the overall change in position of an object, regardless of the path it took to get there. Displacement can be positive, negative, or zero depending on the direction and distance of the movement.

To find the vertical displacement of the basic graph to produce a graph of y = pi - 3 cos(x - 2), we need to compare the given equation with the general cosine function y = A cos(Bx - C) + D.

To find the factors of the polynomial function g(x) = x^3 + 2x^2 - x - 2, we can use different methods such as long division, synthetic division, or grouping.

Using long division, we can divide g(x) by (x-1), which is a factor by the factor theorem:

            x^2 + 3x + 2

    ___________________________

x - 1 | x^3 + 2x^2 - x - 2

    - (x^3 - x^2)

      --------

          3x^2 - x

      - (3x^2 - 3x)

        ----------

                 2x - 2

        - (2x - 2)

          --------

                   0

Therefore, we have factored g(x) as:

g(x) = (x - 1)(x^2 + 3x + 2)

We can further factor the quadratic term using factoring or quadratic formula to obtain the complete factorization of g(x).

The factors of polynomial function g(x) = x³ + 2x² - x - 2 are (x-1), (x+1), and (x+2).

This can be obtained by factoring the polynomial using the grouping method.

Using this method, we group the first two terms together and the last two terms together, resulting in (x²{2 + 2)(x-1) = 0. This gives us two possible roots, x = 1 and x = ±√2i.

However, as we are only interested in real factors, we only consider the real root of x = 1.

G(x) can then be divided by (x-1) using linear long division, yielding the quotient x² + 3x + 2. This quotient can then be factored as (x+1)(x+2). Therefore, the factors are (x-1), (x+1), and (x+2).

The measure of the angle between the vectors is approximately 41.41 degrees.

When we join two line segments at a single point, an angle is formed, or we can say, an Angle is a combination of two line segments at a common endpoint. This common point is called Vertex of the angle and the two line segments are sides or arms of the angle formed.The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

To find the angle between two vectors, we can use the dot product formula:

cos(theta) = (u · v) / (|u| |v|)

where u · v is the dot product of u and v, and |u| and |v| are the magnitudes of u and v, respectively.

First, let's calculate the dot product of u and v:

u · v = 3 × 4 + 4 × 3 = 24

Next, we need to calculate the magnitudes of u and v:

|u| = √(3² + 4²) = 5

|v| = √(4² + 3²) = 5

Now we can plug these values into the formula for cosine:

cos(theta) = (u · v) / (|u| |v|)

cos(theta) = 24 / (5 * 5)

cos(theta) = 24 / 25

To find the measure of the angle, we need to take the inverse cosine (or arccos) of this value:

theta = arccos(24/25)

theta ≈ 0.7227 radians or 41.41 degrees

So the measure of the angle between the vectors is approximately 41.41 degrees.

the scale factor used in the dilation of triangle D to create triangle D' is one-third. This means that every length in triangle D' is one-third the length of the corresponding length in triangle D.

How to solve the question?

To determine the scale factor used in the dilation of triangle D to create triangle D', we need to compare the corresponding sides of both triangles. The corresponding sides of two similar triangles are proportional, meaning that they have the same ratio.

In this case, we can see that the length of every side of triangle D' is one-third the length of the corresponding side of triangle D. For example, the length of the shortest side of triangle D is 18, while the length of the shortest side of triangle D' is 6. Similarly, the length of the longest side of triangle D is 30, while the length of the longest side of triangle D' is 10.

We can use this information to find the scale factor by dividing the length of any side of triangle D' by the length of the corresponding side of triangle D. Let's choose the shortest side for this calculation:

scale factor = length of corresponding side in D' / length of corresponding side in D

scale factor = 6 / 18

scale factor = 1/3

Therefore, the scale factor used in the dilation of triangle D to create triangle D' is one-third. This means that every length in triangle D' is one-third the length of the corresponding length in triangle D.
