(a)  the probability of generating 999999 is [tex](1/10)^6[/tex]

(b) the probability of generating 703928 is [tex](1/10)^6[/tex]

(c) the probability of generating a sequence of six identical digits is [tex](1/10)^6[/tex]

(d)  the probability of generating a sequence with no identical digits is  15,120/1,000,000.

(e)  the probability of generating a sequence with exactly one repeated digit is[tex]10 * 6 * (9^4).[/tex]

Probability is described as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

The probability of generating a sequence with no identical digits is calculated as  (10/10) * (9/10) * (8/10) * (7/10) * (6/10) * (5/10) = 15,120/1,000,000.

We start by choosing  the digit to be repeated, which can be done in 10 ways and the next thing is to choose the position of the repeated digit, and can be done in 6 ways.

We then see that remaining four positions can be filled out with any of the other 9 digits and this can also be   done in [tex]9^4[/tex] ways.

So we can conclude that the number of possibilities in this case is [tex]10 * 6 * 9^4.[/tex]

Using the formula of compound interest, the number of years is 7.6 years

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period. It is different from simple interest, where interest is not added to the principal while calculating the interest during the next period.

The formula of compound interest is given as;

[tex]A = P(1 + \frac{r}{n} )^n^t[/tex]

But in this case, the interest was compounded continuously

[tex]A = Pe^r^t[/tex]

Answer:

Step-by-step explanation:

You want the formula that describes the decay of an insect population from 10000 by 9% per year, and the years it takes for the population to decline by half.

An exponential function will have the form ...

  f(t) = (initial value) · (growth factor)^t

where ...

  growth factor = 1 + growth rate

Here, the growth rate is -9% per year, so the growth factor is ...

  1 -9% = 1 -0.09 = 0.91

The population is then ...

  f(t) = 10000·0.91^t . . . . . formula for number of insects

We can solve for t when f(t) = 5000 (half the original population):

  5000 = 10000·0.91^t

  1/2 = 0.91^t . . . . . . . . . . . divide by 10,000

  ln(1/2) = t·ln(0.91) . . . . . take logarithms

  t = ln(0.5)/ln(0.91) ≈ 7.3496 ≈ 7.3 . . . . years

It would take about 7.3 years for the population to reduce to less than half its present size.

__

Additional comment

We have rounded the time period to the nearest tenth, 7.3 years. At the end of that period, the population is modeled to be about 5023, not quite "less than half." To get below half the original population would take almost 7.35 years.

Step-by-step explanation:

The answer has to be A or D because they're the only ones that look like real box-and-whisker plots. The mean is the line in the middle of the "box", so calculating the mean should be easy enough.

Add all the numbers together and then divided by the number of numbers.

56+72+75+98+73+86+48+95+69+88+75+92 = 972

There are 12 numbers.

972/12 = 77.25

Only option D represents the proper mean.

Rounding 473,615 to the nearest hundred gives us 473,600.

We have,

Rounding a number to the nearest hundred means that you are looking at the digit in the tens place of the number.

If that digit is 5 or greater, you round up the digit in the hundreds place, and if it is less than 5, you keep the digit in the hundreds place the same.

In the case of 473,615, the digit in the tens place is 1, which is less than 5. So we keep the digit in the hundreds place (3) the same and round the remaining digits to zero.

The system has an infinite number of solutions, but the only solution is (a, b) = (0, 0).

The given system of equations can be solved using the substitution method. We can begin by solving the first equation,[tex]a^2 + b^2[/tex], for either a or b. Let's solve for a:

[tex]a^2 + b^2 = 0[/tex]

[tex]a^2 + b^2 = 0[/tex]

[tex]a^2 = -b^2[/tex]

[tex]a = \pm\sqrt(-b^2)[/tex]

We can substitute this expression for a into the second equation, [tex]3a^2 - 2ab - b^2 = 0[/tex], and simplify:

[tex]3(\pm\sqrt(-b^2))^2 - 2(\pm\sqrt(-b^2))b - b^2 = 0[/tex]

[tex]3b^2 - 2b^2 - b^2 = 0[/tex]

0 = 0

Since 0 = 0, this means that the system of equations has an infinite number of solutions. In other words, any values of a and b that satisfy the equation [tex]a^2 + b^2 = 0[/tex] will also satisfy the equation [tex]3a^2 - 2ab - b^2 = 0[/tex]

However, the equation [tex]a^2 + b^2 = 0[/tex] only has a single solution, which is a = b = 0. Therefore, the solution to the system of equations is (a, b) = (0, 0).

The image polygon P'S'R'T' has vertices P'(-5, 1), S'(0, -1), R'(3, -2), and T'(-2, -4).

To determine the image vertices of P' when the preimage is rotated 90° counterclockwise, we can use the following formula:

(x', y') = (-y, x)

where (x, y) are the coordinates of the preimage vertex, and (x', y') are the coordinates of the image vertex after rotation.

Using this formula for each vertex of the polygon PSRT, we get:

For P(1, 5), rotating 90° counterclockwise gives us P'(-5, 1).

For S(1, 0), rotating 90° counterclockwise gives us S'(0, -1).

For R(-2, -3), rotating 90° counterclockwise gives us R'(3, -2).

For T(-4, 2), rotating 90° counterclockwise gives us T'(-2, -4).

Answer:

Step-by-step explanation:

Since the given figure is a right triangle, we can use Pythagorean Theorem

where c² = a² + b²

c = 15

15² = a² + b²

Since 15 is the hypotenuse, we can then say that the possible legs of the triangle are less than 15.

225 - a² = b²

we will do trial and error

let a be 14

225 - 14² = b²

b = √29

a = 14cm, b = √29cm, c = 15cm

let a be 13

225 - 13² = b²

b = 2√14

a = 13cm, b = 2√14cm, c = 15cm

let a be 12

225 - 12² = b²

b = 9

a = 12cm, b = 9cm, c = 15cm

You can solve for other possible values using the same process as above. Since there are no conditions whether the lengths of the legs should be a whole number or not then the above dimensions can be considered. If you're looking for an answer that consists of whole numbers then the answer would be a = 12cm, b = 9cm and c = 15cm

Once we have those values, we can plug them into the formula and calculate the area of trapezium PQRS. And that's it!

To start, let's quickly review what a trapezium is. A trapezium, also known as a trapezoid, is a four-sided geometric shape with two parallel sides (called the bases) and two non-parallel sides (called the legs). The distance between the two parallel sides is known as the height.
In order to find the area of a trapezium, we use the formula:
Area = (sum of bases x height) / 2
So for trapezium PQRS, we need to identify the length of its two bases and its height in order to use this formula.
Without any specific measurements given in your question, I'll assume we don't have any numerical values to work with. Instead, let's use variables to represent the length of each base and the height.
We can call the shorter base PQ, and the longer base SR. Let's say PQ has a length of 'a' units, and SR has a length of 'b' units. For the height, let's call it h.
So, the formula for the area of trapezium PQRS becomes:
Area = ((a + b) x h) / 2
This means that to find the area of the trapezium, we simply need to know the lengths of the two bases (a and b) and the height (h).
Once we have those values, we can plug them into the formula and calculate the area of trapezium PQRS. And that's it!

The value of sin Ф is 72/97.

We have,

Since cos Ф = -65/97 and Ф terminates in quadrant III, we know that cos Ф is negative (since cosine is negative in quadrants II and III).

We can use the Pythagorean identity to find sin Ф:

sin² Ф + cos² Ф = 1

Substituting cos Ф = -65/97, we get:

sin² Ф + (-65/97)² = 1

Simplifying, we get:

sin² Ф = 1 - (-65/97)²

Taking the square root of both sides (since sin Ф is positive in quadrant III), we get:

sin Ф = √(1 - (-65/97)²)

sin Ф = √(1 - 4225/9409)

sin Ф = √(5184/9409)
