The probability that she will make a basket on or before her last attempt within her average waiting time are 1/8 and 2/8

Probability of an event is a measurement of how likely an event can occur as an outcome of a random experiment.

Probability ranges from 0 to 1, both inclusive. Events whose probability is closer to 0 are rarer to occur than those whose probabilities are closer to 1 (relatively).

When converted to percentage, we just need to multiply its decimal representation by 100. In percentage form, the probability ranges from 0% to 100%.

Given;

Hannah makes 5 out of 8 attempted free-throws

Now,

The average waiting time of hannah to make her first basket=5/8

The probability of hannah making basket at her last attempt=1/8

The probability of hannah making basket before her last attempt= 2/8

Therefore, the probabilty will be 1/8 and 2/8.

Answer:

3c=3x+6

Step-by-step explanation:

-2+3c=2x+6+x

-2+3c=3x+6      First combine the x on the right side.

-2+3c=3x+6

+2            +2    Add 2 to both sides to eliminate 2 on the left side.

3c=3x+6

The simplified expression is ab∛ 3ab².

The correct option is (C).

Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner.

For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as [tex]3^4[/tex], where 4 is the exponent and 3 is the base.

Given:

2ab (∛192ab²) -5(∛81 [tex]a^4b^5[/tex])

Now, factorizing the terms as

192ab² = 2 x 2 x 2 x 2 x 2 x 2 x 3 x a x b x b

81 [tex]a^4b^5[/tex] = 3 x 3 x 3 x 3 x a x a x a x a x b x b x b x b x b

So, 2ab (∛192ab²) -5(∛81 [tex]a^4b^5[/tex])

= 2ab (∛2 x 2 x 2 x 2 x 2 x 2 x 3 x a x b x b) -5(∛3 x 3 x 3 x 3 x a x a x a x

                                                                                    a x b x b x b x b x b)

= 2ab ( 2 x 2 ∛ 3 x a x b x b) -5( 3 x a x b ∛3 x a x b x b )    

= 8ab ∛ 3ab² - 15ab∛ 3ab²

Answer: How many cards are in a packet?

Step-by-step explanation:

The range of sina(3cos2a cos4a 3sin2a sin2a cos2a) ^ tan a(sec a -sina tana) where a is not an integer multiple of 7t/2.

The range of sina(3cos2a cos4a 3sin2a sin2a cos2a) ^ tan a(sec a -sina tana) where a is not an integer multiple of 7t/2 can be calculated using the following formula:

Range = Maximum Value - Minimum Value

The expression inside the parentheses can be simplified to 3cos2a cos4a + 3sin2a sin4a and the expression inside the exponential can be simplified to tan2a (1 / cos2a - sin2a). This gives us the expression

Range = 3cos2a cos4a + 3sin2a sin4a ^ tan2a (1 / cos2a - sin2a)

To calculate the maximum and minimum values, we can use derivatives to find the critical points of the expression. Taking the first derivative with respect to a, we get

d/da (3cos2a cos4a + 3sin2a sin4a ^ tan2a (1 / cos2a - sin2a)) = 0

Solving this equation gives us the critical points of a = ±7t/6. Using these values, we can calculate the maximum and minimum values of the expression.

Maximum Value = 3cos14t/6 cos8t/6 + 3sin14t/6 sin8t/6 ^ tan4t/3 (1 / cos14t/6 - sin14t/6)

Minimum Value = 3cos22t/6 cos16t/6 + 3sin22t/6 sin16t/6 ^ tan4t/3 (1 / cos22t/6 - sin22t/6)

Finally, using the formula for the range, we can calculate the range of the expression to be

Range = 3cos14t/6 cos8t/6 + 3sin14t/6 sin8t/6 ^ tan4t/3 (1 / cos14t/6 - sin14t/6) - (3cos22t/6 cos16t/6 + 3sin22t/6 sin16t/6 ^ tan4t/3 (1 / cos22t/6 - sin22t/6))

This expression gives us the range of sina(3cos2a cos4a 3sin2a sin2a cos2a) ^ tan a(sec a -sina tana) where a is not an integer multiple of 7t/2.

We can see from table that when x= -3, the f(x) have the same y with g(x). Also when x= -1, the f(x) have the same y with g(x).

The associated probabilities are A = At least two but no more than five buffers occupied.

There are a total of 2^6 = 64 possible outcomes when rolling 6 dice.

To find the probability of event A, we need to find the number of outcomes where at least two but no more than five buffers are occupied.

This can be done by summing the probabilities of each individual outcome where two, three, four, or five buffers are occupied and subtracting the probabilities where six or zero buffers are occupied.

The probability of two buffers being occupied is (6 choose 2)(1/64) = 15/64

The probability of three buffers being occupied is (6 choose 3)(1/64) = 20/64

The probability of four buffers being occupied is (6 choose 4)(1/64) = 15/64

The probability of five buffers being occupied is (6 choose 5)(1/64) = 6/64

So the probability of event A is (15/64) + (20/64) + (15/64) + (6/64) = 56/64.

B = At least three but no more than five buffers occupied.

To find the probability of event B, we need to find the number of outcomes where at least three but no more than five buffers are occupied.

This can be done by summing the probabilities of each individual outcome where three, four, or five buffers are occupied and subtracting the probability where six buffers are occupied.

The probability of three buffers being occupied is (6 choose 3)(1/64) = 20/64

The probability of four buffers being occupied is (6 choose 4)(1/64) = 15/64

The probability of five buffers being occupied is (6 choose 5)*(1/64) = 6/64

So the probability of event B is (20/64) + (15/64

Answer:

Slope = 4/3

Step-by-step explanation:

The coordinates are,

→ x1 = 6, y1 = 0

→ x2 = 0, y2 = -8

Formula we use,

→ Slope(m) = (y2 - y1)/(x2 - x1)

Now required slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (-8 - 0)/(0 - 6)

→ m = (-8)/(-6)

→ m = 8/6

→ [ m = 4/3 ]

Hence, the slope is 4/3.

The function f(x) = x^2 + 1 can be graphed using the coordinates (x, y) where x is the x-coordinate, and y is the y-coordinate.

This function can be written as y = x^2 + 1. Using this equation, we can plot the graph of the function. To plot the graph, we need to plot points on the x-axis and y-axis. The x-axis is the horizontal line and the y-axis is the vertical line.

For example, let us take a point x = 0. Substituting x = 0 in the equation f(x) = x^2 + 1, we get y = 0^2 + 1, which is equal to 1. So, we can plot the point (0,1) on the graph. Similarly, we can plot the point (1,2), (2,5), (3,10), (4,17), (5,26), and so on.

By plotting all these points, we can get the graph of the function f(x) = x^2 + 1. This graph is a parabola with vertex at (0,1). It is an increasing function, which means that as the value of x increases, the value of y also increases. The graph is also symmetric about the y-axis.

The missing coordinate of P, using the fact that P lies on the unit circle in the given quadrant is √(2/7) or √(2/7)

The unit circle is a circle with a radius of 1 centered at the origin (0,0) on a coordinate plane. If a point P lies on the unit circle, then the distance from the origin to P is 1.

We can use the distance formula to find out the missing coordinate of P.

The distance formula:   [tex]d = \sqrt((x2 - x1)^2 + (y2 - y1)^2)[/tex]

where (x1, y1) is origin and (x2, y2) is the point P.

Given in the problem that P is in Quadrant IV, then the (x, y)-coordinate is negative.

So we can use the given information and the distance formula to find out the missing coordinate.

[tex]d = \sqrt((x2 - 0)^2 + (y2 - 0)^2) = 1[/tex]

x2 = -5/7, y2 = -5/7

[tex]d = \sqrt((-5/7 - 0)^2 + (-5/7 - 0)^2) = \sqrt((-5/7)^2 + (-5/7)^2) = \sqrt(25/49 + 25/49) = \sqrt(50/49) = \sqrt(2/7) = 1[/tex]

Step-by-step explanation:

The parametric vector represents a line, whose slope and intercept are 12 and - 35, respectively.

Parametric functions are multi-dimensional functions in terms of a variable t that is a real number. In this problem we find a parametric function with coordinates, that is, a vector of the form (x, y) = (f(t), g(x)) and we are supossed to determine the rectangular form of such function, that is, a function of the form:

y = f(x)

The rectangular form of the function is a line if and only if the resulting expression is of the form:

y = m · x + b

Where:

First, write the components of the parametric functions:

x = 2 · t + 3

y = 24 · t + 1

Second, clear variable t in each parametric expression:

t = (x - 3) / 2

t = (y - 1) / 24

Third, eliminate parameter t by transitive property:

(x - 3) / 2 = (y - 1) / 24

Fourth, obtain the equation of the line:

24 · (x - 3) = 2 · (y - 1)

24 · x - 72 = 2 · y - 2

24 · x - 70 =  2 · y

y = 12 · x - 35

The spaceship's velocity modulus increased due to the firing of the brake rocket in order to transfer the spacecraft into a circular orbit of the Moon satellite.

When approaching the Moon, a spacecraft follows a parabolic trajectory which is almost tangent to the Moon's surface. At the moment of maximum approach, the brake rocket is fired for a short time interval. This causes a decrease in the spacecraft's velocity and an increase in its centripetal force. This, in turn, causes the spacecraft to move away from the Moon and into a circular orbit of a Moon satellite. The increased centripetal force causes the spacecraft to accelerate, and thus its velocity modulus increases. The magnitude of this increase in velocity modulus depends on the duration and power of the brake rocket. In conclusion, the velocity modulus of the spacecraft increases due to the firing of the brake rocket.
