Find the length of CB

Answer: 150 Cubes.

Step-by-step explanation:

Volume of cuboid is l*b*h, Volume of cube is S^3.

= 75*50*40 = 1,50,000 CM, = 0.1m= 10cm^3= 1000

No of cubes in one cuboid= volume of cuboid/volume of cube

1,50,000/1000= 150 cubes.

Answer: A = 5

Step-by-step explanation:

So, we are given a function, with a point: we can substitute (x,y) from the coordinate into x and f(x) in the function. (recall that f(x) is just a fancy way of saying y).

so:

[tex]-1 = \frac{2(0) + 5}{0 - A}[/tex]

[tex]-1 = \frac{5}{-A}[/tex], (we can drop the negative sign from both sides here)

[tex]\frac{5}{5} = \frac{5}{A}[/tex], (recall 1 = x/x where x is literally any number)

hence we can see that A = 5

The required value of the trigonometric function is sin (α - β) = - 10.96/15.

Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.

The trigonometric ratios are given in the question, as follows:

sin α = -2/5 and cos β = -1/3

So cos α = √1 - (-2/5)² = √(1 - 4/25) = √21/5

And sin β = √1  - (-1/3)² = √(1 - 1/9) = √8/3

We have to determine the value of sin (α - β).

According to trigonometric identity,

sin (α - β) =  sinα cos β - cos α sin β

Substitute the values of sin α = -2/5 and cos β = -1/3,

sin (α - β) = (-2/5)( -1/3) - (√21/5)(√8/3)

sin (α - β) = 2/15 - (√21×8)/15

sin (α - β) = 2/15 - (√168)/15

sin (α - β) = 2/15 - 12.96/15

sin (α - β) = - 10.96/15

The term that should be added to the expression to make the expression perfect square trinomial is 169/4. The expression then becomes : (y - 13/2)²

What is meant by a perfect square trinomial?

By multiplying a binomial by another binomial, perfect square trinomials—algebraic equations with three terms—are created. A number can be multiplied by itself to produce a perfect square. Algebraic expressions known as binomials are made up of simply two words, each of which is separated by either a positive (+) or a negative (-) sign. Similar to polynomials, trinomials are three-term algebraic expressions.

A perfect square trinomial expression can be created by taking the binomial equation's square. If and only if a trinomial satisfying the criterion b² = 4ac has the form ax² + bx + c, it is said to be a perfect square.

Given expression y² - 13y + ?

Comparing with the general equation

a = 1

b = -13

For perfect square trinomial

b² = 4ac

(-13)² = 4 * 1 * c

169 = 4c

c = 169/4

So the expression becomes,

y² - 13y + 169/4 = (y - 13/2)²

Therefore the term that should be added to the expression to make the expression perfect square trinomial is 169/4.

Answer:

(4, -1) and (-6, 9).

Step-by-step explanation:

To find the fourth vertex of a parallelogram, we need to find the vector that represents the displacement from one of the given vertices to another, and then add that vector to the third given vertex. Since parallelograms have opposite sides that are equal in length and parallel, adding the same displacement vector to two of the given vertices will give us the coordinates of the other two vertices.

One possible displacement vector is the difference between the first and second given vertices, or (1 - (-4), -2 - 3) = (5, -5). Adding this vector to the third given vertex, (-1, 4), gives us the fourth vertex at (4, -1).

Another possible displacement vector is the difference between the second and third given vertices, or (-1 - 1, 4 - (-2)) = (-2, 6). Adding this vector to the first given vertex, (-4, 3), gives us the fourth vertex at (-6, 9).

So the two possible locations of the fourth vertex are (4, -1) and (-6, 9).

Speed of bicycle in miles per hour will be 12.85 mi/h.

What is the definition of speed?

The following is the definition of speed:

The rate at which the position of an item changes in any direction.

The ratio of distance travelled to time spent travelling is described as speed. Speed is a scalar number since it has just one direction and no magnitude.

Formula for Speed

The speed formula is as follows:

s=d/t

Where,

s denotes the speed in metres per second, d the distance travelled in metres, and t the time in seconds.

Now,

Given Diameter=18 inch

then distance covered by cycle in 4 rotation in one second =4*π*diameter

=4*22/7*18

=226.28

Then Speed=226.28 in/s

As 1 mike=63360 inch and 1 hour= 3600 seconds

then Speed in miles/hour=226.28*3600/63360

=12.85 mi/h

hence,

          Speed of bicycle in miles per hour will be 12.85 mi/h.

The answers to the questions are:

a) P(A|B) =  1/3

b) P(B|A) = 1.15

c)  A. A student given a $1 bill is more likely to have kept the money.

What is the probability?

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

Because the probability of 0.659 is almost two times greater than 0.341

Assuming the following table:

                                                  Purchased Gum      Kept the Money    Total

Students Given 4 Quarters              25                              19                      44

Students Given $1 Bill                       13                               26                    39

Total                                                   38                              45                     83

a. find the probability of randomly selecting a student who spent the money, given that the student was given a $1 bill.

For this case let's define the following events

B= "student was given $1 Bill"

A="The student spent the money"

For this case we want this conditional probability:

P(A|B) = P(A And B) / P(B)

We have that

P(A) = 38/83,  P(B) = 39/83

P(A And B) = 13/83

And if we replace we got:

P(A|B) =  (13/83)/(45/83) = 13/39 = 1/3

b. find the probability of randomly selecting a student who kept the money, given that the student was given a $1 bill.

For this case let's define the following events

B= "student was given a $1 Bill"

A="The student kept the money"

P(A|B) = P(A And B) / P(B)

We have that

P(A) = 45/83,  P(B) = 39/83

P(A And B) = 26/83

And if we replace we got:

P(B|A) =  (45/83)/(39/83) = 45/39 = 1.15

c. what do the preceding results suggest?

For this case the best solution is:

A. A student given a $1 bill is more likely to have kept the money.

Because the probability of 0.659 is almost two times greater than 0.341

Hence, The answers to the questions are:

a) P(A|B) =  1/3

b) P(B|A) = 1.15

c)  A. A student given a $1 bill is more likely to have kept the money.

Note that the pattern in the table is that the perimeter of a square with area x is four times the square root of x. We can express this relationship as:

f(x) = 4 * √(x)

We know that the area of a square is calculated as the square of its side length, which means that the side length of a square with area x is the square root of x. Therefore, the length of the side of the square can be expressed as:

s = √(x)

To calculate the perimeter of the square, we simply add up the lengths of all four sides:

P = 4s = 4 * √(x)

So, the function f(x) in the table represents the perimeter of a square with area x, which can be calculated using the equation:

f(x) = 4 * √(x)

We can form 15 different 4-digit numbers using the digits 1, 2, 3, 7, 8, and 9, without repetition. Out of these, 30 are even numbers. We used the concept of combination to find these numbers.

Combination is a mathematical technique used to calculate the number of ways in which a group of objects can be selected from a larger set, without considering their order.

We can use the combination formula to find the total number of possible combinations:

C(4, 3) = 4! / (3! * 1!) = 4

This means that we can form four different 3-digit numbers using the digits 1, 2, 3, and 4, without repetition.

Now, coming back to our original problem, we need to form 4-digit numbers using the digits 1, 2, 3, 7, 8, and 9, without repetition. Using the same combination formula, we can find the total number of possible combinations:

C(6, 4) = 6! / (4! * 2!) = 15

This means that we can form a total of 15 different 4-digit numbers using the given digits.

Next, we need to find out how many of these numbers are even. An even number is a number that is divisible by 2, and in our case, this means that the last digit of the number must be either 2, 8, or a combination of 1 and 7.

To find the number of even 4-digit numbers, we can use the same combination formula, but this time we have to consider only 3 digits (2, 8, and a combination of 1 and 7) for the last digit:

C(3, 1) * C(5, 3) = 3 * 10 = 30

This means that we can form a total of 30 different 4-digit even numbers using the given digits.
