The probability that the ace of spades will be revealed before any face card (the jack, queen, or king) is 0.0769.

Probability refers to potential.This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability has been applied into mathematics to predict the likelihood of different events.

The likelihood is based on the range of potential outcomes. the total number of possible outcomes. As an illustration, since there is only one way to get a head and a total of two possible results, the likelihood of flipping a coin and getting heads is one in two. a tail or a head.

According to given data;

Let's look at the first few probabilities; we're going to do this in reverse order, in order to find a pattern:

P(O,O,O,AS)=39/52)*(38/51)*(37/50)*(1/49)

                  =(39*38*37/3!)/(52*51*50/3!)*1/49

P(O,O,AS)=(39/3)(52/3)×1/49

        but we know that;

(n/2)=n(n-1)/2!

P,(O,O,AS) =(39/2)/(52/2)  *1/50

P(AS)=(39/0)/(52/0) *(1/52)

We now have

P(AS)+P(O,AS)+P(O,O,AS)+P(O,O,O,AS)

FROM THIS CALCULATE ;

P=0.0769

The arc YZ represented in the diagram, its length is :

2π/3 or 4π/6

A circle's arc can be formed by any two points on its circumference.

A circle's arc length (S) = r(θ), where r is the radius and theta is the central angle in radians.

Given WY = XZ = 6,

So YZ = TZ = 3radius

and m∠XY = 140°.

so, m∠YZ = 180° - 140°.  (As a semicircle with a central angle of 180°.)

m∠YZ = 40°.

then,  m∠YZ = (40/180)°×π rad.

m∠YZ = 2π/9 rad.

then, Arc length of YZ =  = 3×(2π/9).

YZ = 6π/9.

Answer: y+5=3/8*(x-4)

Step-by-step explanation: Find the slope using m = y2-y1/x2-x2 which is the change of y over change of x, so the slope is m=3/8. Use the slope 3/8, and a given point (4, -5) to substitute for x1 and y1 in point slope form y -y1 = m(x-x1). So y-(-5)=3/8*(x-(4)). Now we simplify the equation so it's y+5=3/8*(x-4).

Based on the numbers given in the distribution, the standard deviation can be found to be 1.49

To find the standard deviation, you first have to find the mean of the distribution:

= (0 + 0 + 1 + 1 + 1 + 2 + 2 + 3 + 5 ) / 9

= 15 / 9

= 1.67

You can then find the variance using financial calculators to be:

= 2.2222222

Given:

The car ride from Kiley's house to the airport.

Distance =24.3 miles.

Time =1/2 hour.

We know that

Substitute Distance =24.3 miles and time =1/2 hour to compute the average rate of the car ride from Kiley's house to the airport.

Hence the average rate of the car ride from Kiley's house to the airport is 48.6 miles per hour.

2)

Given that they walked 3/4 hours to the waiting area and covered the distance of 1.2 miles.

Distance =1.2 miles.

Time =3/4 hours.

we know that

Substitute distance =1.2 miles and time =3/4 hours to compute the average rate of the walk from the car to the waiting area by the gate, at the airport.

Multiplying 1.2 and 4, we get 4.8

Dividing 4.8 by 3, we get 1.6

Hence at the airport, the average rate of the walk from the car to the waiting area by the gate is 1.6 miles per hour.

The equation y = 2x² - 12x + 23 describes the function graph that includes a vertex at (3, 5) and passes through the point (5, 13).

The vertex of a parabolic equation is at the point and the vertex form is y = a(x - h)2 + k, where a, h, and k are constants (h, k).

Find the function whose graph has the vertex at (3, 5) and passes through the point in the question (5, 13).

Assuming it to be a parabolic function, we know that a parabolic equation's vertex form is y = a(x - h)2 + k, where a, h, and k are constants, and the vertex is located at the position (h, k).

As the vertex of the necessary function is at the position (3, 5), we may substitute h = 3 and k = 5 to obtain the following equation in the above equation:

y = a(x - 3)² + 5

Now that we know that the graph passes through the point (5, 13), we can change the original equation to read:

13 = a(5 - 3)² + 5,

or, 13 = 4a + 5,

or, 4a = 13 - 5 = 8,

or, a = 2.

We obtain the following from the equation y = a(x - h)2 + k by inserting a = 2, h = 3, and k = 5:

y = 2(x - 3)² + 5,

alternatively, y = 2(x² - 6x + 9) + 5,

alternatively, y = 2x² - 12x + 18 + 5,

Alternatively, y = 2x² - 12x + 23.

As a result, the function graph with the vertex at (3, 5) and the point of intersection (5, 13) yields the equation y = 2x² - 12x + 23.

Step-by-step explanation:

544 × .294 = 159.936, which rounds to 160.

Using an exponential function, it is found that:

a) During the first five days, the population of organism A grew by a factor of 2^5.

b) During the next three days, the population of organism B decayed by a factor 2^(-3).

c) The expression for the total change is of 2².

An exponential function is modeled according to the following rule:

[tex]y = ab^x[/tex]

In which:

For the first five days, the population doubles each day, hence the rate of change is of:

b = 2.

The growth factor will be of:

y = 2^5 = 32

During the next three days, the population cuts in half each day, hence the rate of change is of:

b = 0.5.

Then the decay factor is of:

y = (0.5)³ = (1/2)³ = 2^(-3).

Applying properties of exponents, over the entire period, the change in the population will be of:

2^5 x 2^(-3) = 2^(5 - 3) = 2².

As when we multiply two terms with the same base and different exponents, we keep the bases and add the exponents.
