Answer:

So, about 2.28% of men in the country are no more than 64 inches tall.

Step-by-step explanation:

First, we need to standardize the value of 64 inches to a z-score:

z = (64 - 68) / 2 = -2

We can use a standard normal distribution table or a calculator to find the percentage of men who are no more than 64 inches tall:

P(Z ≤ -2) = 0.0228

Answer:

1,500 beds

Step-by-step explanation:

Occupancy rate  shelter A = 300 x 20/100 = 60

Let capacity of shelter B be X

60% occupancy ==> 60/100 x X = 0.6X

Occupancy rate of A to rate of B is 1: 15 can be expressed as fraction 1/15

Therefore
60/0.6X = 1/15

1 x 0.6X = 60 x 15

0.6X = 900

X = 900/0.6 = 1,500 beds

This function is not one-to-one because different ages can have the same height.

This function f(t) is not one-to-one because different ages can have the same height. For example, two people at age 20 could have the same height, even though one is 20 years old and the other is not. Additionally, two people of different ages can have the same height, such as a 5 year old and a 25 year old with the same height. One-to-one functions require that for every input there is only one output, which is not the case for this function. This is because height is not necessarily determined solely by age, and can be influenced by genetics and other environmental factors. Therefore, for any given age, there could be multiple possible heights, and this function does not satisfy the definition of a one-to-one function.

The volume of the concrete required to be poured for a rectangular prism floor slab are;

11. 5 1/3 cubic yards

12. 74 2/27 cubic yards

A rectangular prism is a polyhedron that consists of six rectangular faces, in which the adjacent faces are perpendicular and opposite faces are parallel.

11. The dimensions of the floor slab = 18' × 24' × 4''

Where the shape of the slab is a rectangular prism, we get;

Width of the floor slab = 24 feet

Length of the floor slab = 18 feet

Height of the floor slab = 4 inches

4 inches = (1/3) ft

The volume of the cement is therefore;

V = 24 ft × 18 ft × (1/3) ft = 144 ft³

The volume of the concrete required to pour a floor slab of the dimensions: 18' × 24' × 4'' is 144 cubic feet

1 yard = 3 feet

The dimensions of the slab are therefore;

Length = 24/3 yards = 8 yards

Width = 18/3 yards = 6 yards

Height = (1/3)/3 yards = (1/9) yards

The volume of the slab = 8 yards × 6 yards× 1/9 yard = 16/3 cubic yards

12. The dimensions of the slab are;

Length of the slab = 80 feet = 80/3 yards

Width of the slab = 60 feet = 60/3 yards = 20 yards

Height of the slab = 5 inches = 5/12 ft = 5/(12 × 3) yard = 5/36 yard

The volume of the concrete slab is therefore;

(80/3) yards × 20 yards × (5/36) yard = 74 2/27 cubic yards

Answer:

16 is correct

Step-by-step explanation:

Your welcome

The volume of the rectangular prism is 400 cubic centimeters which we can calculate using formula: Volume = L * W * H

The volume of rectangular prism can be computed by simply multiplying their dimensions. If the rectangular prism was built with cubes that each have a volume of one cubic centimeter, then the volume of the rectangular prism can be calculated by multiplying the number of cubes in each dimension.

Let's assume that the rectangular prism has a length of "L" cubes, a width of "W" cubes, and a height of "H" cubes. Then, the volume of the rectangular prism can be calculated as follows:

Volume = L * W * H

Each cube has a volume of one cubic centimeter, so the volume of the rectangular prism is equal to the number of cubes it contains. In other words, if the rectangular prism has 10 cubes along its length, 5 cubes along its width, and 8 cubes along its height, then its volume would be:

Volume = 10 * 5 * 8 = 400 cubic centimeters

a. probability of neither a math major nor an engineering major is: 0.1783

b. probability is only an engineering major: 0.5167

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.

Given that,

n(S) = 60

n(math) = n(M) = 183 ⇒ P(M) = n(M)/ n(S) = 183/600

n(engineering) = n(E) = 366 ⇒ P(E) = n(E)/ n(S) = 366/600

n(M∩E) = 56

P (M∩E) = n(M∩E) / n(S) = 56/600

a) probability of neither a math major nor an engineering major is:

P (M' ∩ E') = P (M∪E)'

P (M' ∩ E') = 1 - P (M∪E)

P (M' ∩ E') = 1 - [P(M) + P(E) - P(M∩E)]

P (M' ∩ E') = 1 - [183/600 + 366/600 - 56/600]

P (M' ∩ E') = 0.1783

b)

probability is only an engineering major:

P(E - M) = P(E) - P(M∩E)

P(E - M) = 366/600 - 56/600

P(E - M) = 0.5167

c. 24 feet/second > 0).

d.  the time at which the rock reaches its highest height is 2.5 seconds and 80 feet respectively.

e. the acceleration is given by a(2.5) = -32 feet/second²

The velocity, v(t), of the rock is given by the derivative of the position function s(t) with respect to time,

v(t) = ds(t)/dt = -32t + 80 feet/second.

The acceleration, a(t) = dv(t)/dt = -32 feet/second²

b) v(3) = -32*3 + 80 = 24 feet/second.

This quantity represents the velocity of the rock at t = 3 seconds.

c) At t = 3 seconds, the rock is rising up because the velocity is positive (v(3) = 24 feet/second > 0).

d) the time at which the rock reaches its highest height,

v(t) = 0, we get -32t + 80 = 0, so t = 80/32 = 2.5 seconds.

The height of the rock will be found using the position function s(t), so s(2.5) = -16(2.5)^2 + 80(2.5) = 80 feet.

Answer:

p = 1,400

Step-by-step explanation:

In the simple interest rate formula, each year the same amount of interest is applied, as it's based off the initial amount invested and the interest rate.

[tex]I=P*r*t[/tex]

Where "r" is the interest rate, "t" is time, and "p" is the principle amount, or initial amount invested.

We're given the following values:

Now the only thing is generally speaking, interest is applied annually rather than monthly. So we would need to convert the 3 months into years, which we can do by dividing by 12, giving us: 0.25 years

So we actually have: t = 0.25 years

Now from here we can plug in known values, and leave anything we don't know alone. So we start with our initial formula of:

[tex]I=P*r*t[/tex]

Now from here we plug in i = 21, t = 0.25, r = 0.06 and leave "P" as "P"

[tex]21=P*0.25*0.06[/tex]

Now let's simplify the multiplication on the right side:

[tex]21 = 0.015P[/tex]

Divide both sides by 0.015:

To find the value of k such that the system has a unique solution, no solution, or an infinite number of solutions, we can use the determinant of the coefficient matrix. If the determinant is nonzero, then the system has a unique solution. If the determinant is zero and the system of equations is inconsistent, then the system has no solution. If the determinant is zero and the system of equations is consistent, then the system has an infinite number of solutions. In this case, the determinant of the coefficient matrix is zero, which implies that the system has an infinite number of solutions.

The eigen values and eigen vectors of the matrix can be found by solving the characteristic equation, which is obtained by det(A - λI) = 0, where A is the matrix and I is the identity matrix.

For the matrix

2 1 -1

3 2 -3

3 1 -2

the characteristic equation is

(2 - λ)(3 - λ) - 3 = 0

which gives us λ = 1 and λ = 3 as the eigen values.

The corresponding eigen vectors can be found by solving the system of equations (A - λI)x = 0, where x is the eigen vector.

For λ = 1, the eigen vector is (1, -1, 1).

For λ = 3, the eigen vector is (-1, 2, 1).

This can be seen by noting that f(x) and g(x) both grow without bound as x grows without bound, so the ratio of the two polynomials also grows without bound.

Answer:

Step-by-step explanation:

To solve the equation, we can simplify the expression on the right side of the equation first:

9(7+9) = 9(16) = 144

Then, we can rewrite the equation as:

x + 81 = 144

To solve for x, we can subtract 81 from both sides:

x + 81 - 81 = 144 - 81

x = 63

Therefore, the completed equation is:

63 + 81 = 9(7+9)

Answer:

63

Step-by-step explanation:

First solve the right side of the equation by expanding the parenthesis using the BODMAS and Distributive Law:

9(7 + 9) = 9(16)

             = 144

Now equate the above answer to the left side of the equation:

—- + 81 = 144
—- = 144 - 81

   = 63

Answer: The value of sin(2x) can be found using the identity:

sin(2x) = 2sin(x)cos(x)

Since tan(x) = -1/5, we can use the tangent definition to find the sine and cosine values:

tan(x) = sin(x) / cos(x) = -1/5

Cross multiplying and solving for sin(x), we get:

sin(x) = -5 / sqrt(26)

And using the Pythagorean identity:

cos^2(x) + sin^2(x) = 1

We can find cos(x):

cos(x) = sqrt(1 - sin^2(x)) = sqrt(1 - (-5/sqrt(26))^2) = sqrt(26) / sqrt(26) = sqrt(26) / sqrt(26) = sqrt(26) / 5

Finally, substituting the values of sin(x) and cos(x) into the formula for sin(2x), we get:

sin(2x) = 2sin(x)cos(x) = 2 * (-5 / sqrt(26)) * (sqrt(26) / 5) = -2 sqrt(26) / 5 = -2 sqrt(26) / 5 = -2 sqrt(26) / 5

So the exact value of sin(2x) is -2 sqrt(26) / 5.
