Step-by-step explanation:

(a) According to the question, a composer wrote [tex]10[/tex] symphonies, [tex]4[/tex] piano concerts (piano and orchestra) and [tex]35[/tex] piano sonatas (solo piano):

Here, determine how many ways are there to play first a symphony and then piano concerto.

So, the probability is [tex](10P1) (4P1) = (10)(4)= 40[/tex]

Therefore, there are [tex]40[/tex] ways to play first a symphony and then piano concerto.  

(b)The manager of a radio station decides that on each successive evening, a symphony will be played followed by a piano concerto followed by a sonata.

Here determine how many nights could be carried out before the same program would get repeated.

So, the probability would be [tex](35)(10)(4)=1440[/tex]

Therefore, [tex]1440[/tex] nights are carried out before the same program gets repeated.

Now, to calculate the years:  [tex]\frac{1440 nights}{365days} = 3.95 years[/tex]

Therefore, it would be [tex]3.95[/tex] years.

What is probability?

Probability is the method to measure the occurred events or the occurrence of the events. It is also used to analyze the outcomes of random events. For example, to calculate the probability of a playing card which is 52 in numbers. And it is divided into four cards and each are in the count of 13.These four cards are heart, spades, diamond and club.

Step-by-step explanation:

Do you mean width equal 5

The percent of the first change is greater by 2.36%.

Time in 1st week = 28.8 sec

Time in 2nd week = 27.6 sec

Time in 3rd week = 27.1 sec

∴ Change of time from week 1 to week 2 = (28.8 - 27.6) sec

                                                                    = 1.2 sec

∴ Percent of change from week 1 to week 2 = [tex]\frac{time change}{1st week time} \times 100[/tex] %

                                                                         = [tex]\frac{1.2}{28.8} \times 100[/tex] %

                                                                         = 4.17%

∴ Change of time from week 2 to week 3 = (27.6 - 27.1) sec

                                                                     = 0.5 sec

∴ Percent of change from week 2 to week 3 = [tex]\frac{Time change}{2nd week time} \times 100[/tex] %

                                                                          = [tex]\frac{0.5}{27.6} \times 100[/tex] %

                                                                          = 1.81%

∴ The greater change was in the first week. The amount by which it was greater is = (4.17 - 1.81) %

                = 2.36%

Answer) The percent of the first change is greater by 2.36%.

The difference of time taken by Rosa and Maya to ran the hurdles is 4.242 seconds .

The correct option is B .

Given, time taken by Rosa and Maya to ran the hurdles.

Time taken by Rosa to ran the hurdle = 58.32 seconds .

Time taken by Maya to ran the hurdle = 54.078 seconds .

Difference between the time taken:

Rosa is taking more time to cover the distance than Maya . Thus the speed of Rosa is less than the speed of Maya .

Relationship between speed, time and distance.

Distance = Speed × Time

Subtract time taken by Rosa to ran the hurdle from time taken by Maya to ran the hurdle.

= 58.32 - 54.078

= 4.242 seconds

The domain of the function f(2x) is (-1, 1).

Given that a function f has domain (-2,2) and range (-3,5).

We need to determine the domain of the function f(2x).

To determine the domain of the function f(2x), we need to consider how the original domain (-2,2) is affected by the transformation of multiplying the input by 2.

When we multiply x by 2, it stretches or compresses the function horizontally.

In this case, multiplying by 2 will stretch the original domain by a factor of 1/2.

To find the new domain, we divide the original domain endpoints by 2:

New domain = (-2/2, 2/2) = (-1, 1)

Therefore, the domain of the function f(2x) is (-1, 1).

Since the lateral faces are rectangles and not 12-sided polygons like the bases, the polyhedron is an irregular polyhedron.

The absolute value equation is:

|M - 430g| = 20g

And the solutions are M = 410g and M = 450g

b) No, the mass is not acceptable.

We know that the recomended mass is 0.43kg, with an accepted error of 20 grams.

Where:

0.43kg = 0.43*1000g = 430g

Then the minimum mass accepted is: 430g - 20g = 410g

The maximum mass accepted is: 430g + 20g = 450g

These are the solutions, and the absolute value equation is, if M is the mass:

|M - 430g| = 20g

b) If the ball has a mass of 423g it is in the accepted range, if now it loses 0.016kg:

0.016kg = 0.016*1000g = 16g

The new mass is:

423g - 16g = 407g

The area of the remaining rectangular plot of land is 4680m²

Area of rectangle:

Area of rectangle means the area covered by the rectangle.

The formula for area of rectangle is

A = l x b

where,

l is the length of the rectangle

b is the breadth or width of the rectangle

Given,

A rectangular plot of land measures 40.0 m by 120.0 m, with a parcel 10.0 m by 12.0 m out of one corner for an electrical transformer.

Here we need to find the remaining area of the rectangular plot land.

For that first, we have to find the area of each separately,

Like,

The area of the rectangular plot is,

A₁ = 40.0 x 120.0 m²

A₁ = 4800m²

Similarly, the area of the electric transformer is,

A₂ = 10.0 x 12.0 m²

A₂ = 120m²

Now the remining area is,

A = A₁ - A₂

A = 4800 - 120 m²

A = 4680m²

Therefore, the area of the remaining rectangular plot is 4680m².
