The probability of the first player being assigned jersey number #16 is 1/30 or approximately 0.0333.
Since there are 30 jerseys numbered from 0 to 29, each jersey number has an equal chance of being assigned to the first player. Therefore, the probability of the first player being assigned the jersey number #16 is the ratio of the favorable outcome (getting jersey #16) to the total number of possible outcomes (all jersey numbers).
In this case, the favorable outcome is only one, which is getting jersey #16. The total number of possible outcomes is 30, as there are 30 jersey numbers available.
Therefore, the probability can be calculated as:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
Probability = 1 / 30
Probability ≈ 0.0333
So, the probability of the first player being assigned jersey number #16 is approximately 0.0333 or 1/30.

The angle x in a right-angled triangle is 12.8°.
What is a right-angled triangle?
A triangle is said to have a right angle if one of the angles is 90 degrees. Right triangles are those with angles at 90 degrees, which are referred to as right angles.
The diagram shows a right-angled triangle with opposite = 12 units and hypotenuse as 54 units.
To find the angle x, apply the formula -
sin(x) = opposite/hypotenuse
sin(x) = 12/54
x = sin^-1(12/54)
x = sin^-1(2/9)
x = 12.84°
Rounding it to nearest tenth gives x = 12.8°.
Therefore, the value of x is 12.8°.

find the scale factor
Answer:
[tex]\dfrac{2}{3}[/tex]
Step-by-step explanation:
Method 1To find the scale factor of the dilation of a figure, simply divide the x-value (or y-value) of a vertex of the dilated image Q'R'S'T' by the x-value (or y-value) of the corresponding vertex of the pre-image QRST.
[tex]\implies \sf Scale\;factor=\dfrac{x_{Q'}}{x_{Q}}=\dfrac{-2}{-3}=\dfrac{2}{3}[/tex]
[tex]\implies \sf Scale\;factor=\dfrac{y_{T'}}{y_{T}}=\dfrac{4}{6}=\dfrac{2}{3}[/tex]
Therefore, the scale factor is 2/3.
Method 2To find the scale factor of the dilation of a figure, first find the lengths of corresponding sides using the distance formula.
[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Distance between two points}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two points.\\\end{minipage}}[/tex]
From inspection of the given diagram:
Q = (-3, 9)R = (3, 6)[tex]\implies QR=\sqrt{(x_R-x_Q)^2+(y_R-y_Q)^2}[/tex]
[tex]\implies QR=\sqrt{(3-(-3))^2+(6-9)^2}[/tex]
[tex]\implies QR=\sqrt{(6)^2+(-3)^2}[/tex]
[tex]\implies QR=\sqrt{36+9}[/tex]
[tex]\implies QR=\sqrt{45}[/tex]
[tex]\implies QR=3\sqrt{5}[/tex]
From inspection of the given diagram:
Q' = (-2, 6)R' = (2, 4)[tex]\implies Q'R'=\sqrt{(x_{R'}-x_{Q'})^2+(y_{R'}-y_{Q'})^2}[/tex]
[tex]\implies Q'R'=\sqrt{(2-(-2))^2+(4-6)^2}[/tex]
[tex]\implies Q'R'=\sqrt{(4)^2+(-2)^2}[/tex]
[tex]\implies Q'R'=\sqrt{16+4}[/tex]
[tex]\implies Q'R'=\sqrt{20}[/tex]
[tex]\implies Q'R'=2\sqrt{5}[/tex]
To find the scale factor of dilation that maps QRST onto Q'R'S'T', divide the length of Q'R' by the length of QR:
[tex]\implies \dfrac{Q'R'}{QR}=\dfrac{2\sqrt{5}}{3\sqrt{5}}=\dfrac{2}{3}[/tex]
Therefore, the scale factor is 2/3.

What is the motion of displacement?
Displacement is the change in the position of an object relative to a reference point over a period of time.
It is usually represented by a vector quantity and is measured in meters (m). The formula for displacement is displacement = final position - initial position. Mathematically, displacement is denoted by s and is equal to the final position (x2) minus the initial position (x1), or s = x2 - x1. As an example, if a person walks a path of length 10 meters, starting at the origin (x1 = 0) and ending at x2 = 10, then their displacement would be s = 10 - 0 = 10 meters. To calculate displacement, we need to know the initial and final positions of the object, and the direction in which it moves.For example, if an object moves from position 5 m to position 10 m, the displacement is 5 m. This can be calculated by subtracting the initial position (5 m) from the final position (10 m). The result is 5 m, which is the displacement of the object.

The rate at which the distance is decreasing is - 30 centimeters per second. Ravi's distance from the first floor when he stepped on escalator is 1250 centimeters.
What is rate?The pace at which one quantity changes in relation to another quantity is known as the rate of change function. Simply said, the rate of change is calculated by dividing the amount of change in one thing by the equal amount of change in another.
a. From the table we can observe that as time increases, his distance from the first floor decreases.
The rate at which the distance is decreasing is given by:
Rate = (d2 - d1)/ (t2 - t1)
= (980 - 1070) / (9 - 6)
= -90 / 3
= -30
Hence, the rate at which the distance is decreasing is - 30 centimeters per second.
b. Ravi's distance from the first floor when he stepped on escalator is calculates as:
d - d1 = m(t - t1)
where, m is the rate.
Here, m = -30.
d - 1070 = (- 30) (t - 6)
d = -30t + 180 + 1070
d = -30t + 1250
The time when he stepped on escalator is 0.
d = -30(0) + 1250
d = 1250
Hence, Ravi's distance from the first floor when he stepped on escalator is 1250 centimeters.

How do you find the domain and range of a function in Class 12?
In Class 12, to find the domain and range of a function, you can use the following steps:
Domain: The domain of a function is the set of all input values for which the function is defined. To find the domain of a function, you need to look at the function and identify any values of x that would make the function output undefined. These values of x are not in the domain of the function.For example, if the function is f(x) = 1/x, the domain of the function is all real numbers except 0, because dividing by 0 is undefined. In this case, the domain of the function is (-∞,0) U (0,+∞)
Range: The range of a function is the set of all possible output values of the function. To find the range, you can look at the function and identify any restrictions on the output values.For example, if the function is f(x) = √x, the domain of the function is all non-negative real numbers, because √x is only defined for non-negative values of x. In this case, the range of the function is [0,+∞)
Note that some functions may have more complex expressions, in such cases, you may have to use algebraic methods to find the domain and range.

Use the explicit rule given to write the first three terms for each sequence. F(n)=16+(1/2)(n-1)
From the explicit rule the first three terms of sequence is 16, 16.5, 17.
What is the explicit rule?The explicit formulae for L-functions are relationships introduced by Riemann for the Riemann zeta function between the sums over complex number zeroes of an L-function and sums over prime powers.The difference between each consecutive term in an arithmetic sequence is constant. An explicit formula for an arithmetic sequence is a = d (n - 1) + c, where d is the common difference between consecutive terms and c = a1.Here given,
F(n) = 16+(1/2)(n-1)
We have to find first three terms.
F(1) = 16 + (1/2)(1-1)
= 16 + 1/2 x 0
= 16
F(2) = 16 + (1/2) (2-1)
= 16 + 1/2
= 16 + 0.5
= 16.5
F(3) = 16 + (1/2) (3-1)

What does a 0.5 Pearson correlation indicate?When a correlation coefficient's magnitude is between 0.5 and 0.7, it means that the variables are moderately correlated. Low correlation between the variables is indicated by correlation coefficients with magnitudes between 0.3 and 0.5.
In this equation, x stands for price, and y for sales.
-22.7x+130.3
The slope indicates the number of units that the sales would change by if we raised the price by one unit. Since our slope is -22.7, this indicates that a 1 unit price increase would result in a 22.7 decrease in sales.
The scatterplot's points are all intersected by the line of best fit, as can be seen. We can also calculate the Pearson correlation coefficient, which gives us -0.998, to add to the evidence. This suggests a very adverse relationship.
For this item we will just need the equation for the line of best fit and the data that has been given in the problem. For the actual sales, we will just refer to the given while we will compute for the predicted sales using the line of best fit.

what kind of motion should you impart to the nozzle of a garden hose so that the resulting stream of water approximates a sine curve?
In order to make the stream of water from a garden hose approximate a sine curve, the nozzle of the hose should be moved in an up-and-down motion.
The reason is because a sine curve is a smooth wave-like pattern that oscillates between positive and negative values. If the nozzle is moved up and down, it will cause the water to be released in a similar wave-like pattern, creating a stream that approximates a sine curve. This is due to the nozzle moving in a sinusoidal motion, which causes the water to be released in the same motion. This kind of motion is known as a harmonic motion, and it's the same motion that causes a wave to have a sinusoidal shape.

Step-by-step explanation:
You want to know what happens when the base of an exponential function is negative.
Powers of a negative numberConsider the exponential function ...
y = a·b^x
For b < 0 and integer values of x, the signs of the corresponding values of y will alternate.
Example
y = 2·(-1)^x
A table of values will be ...
[tex]\begin{array}{ccccccc}x&-1&0&1&2&3\\y&-2&2&-2&2&-2\end{array}[/tex]
Roots of a negative numberFor non-integer values of x, the values of y become more complicated. For fractional values of x, where x has an even denominator, the equation does not produce a real value. Instead, you get a complex number.
For fractional values of x where x has an odd denominator, the power is defined, and the sign will depend on whether the numerator is even or odd.
For irrational values of x, the function value in general is complex.
Of course, there are an infinite number of rational numbers between any pair of numbers on the number line, so the graph will have both positive and negative values, but will not be continuous.

You ride your bike for 3 days in a row. On Monday , you ride 3 and 2/3 miles. On Tuesday, you ride 1 and 1/2 times further. On Wednesday, you ride 1 and 1/4 miles less than Tuesday. Find the total number of miles.
Taking the given ride lengths for 3 consecutive days and adding them the total number of miles ridden by the rider is 14.67 miles.
How is the distance traveled on Tuesday related to Monday's distance?On Tuesday, the distance traveled is 1 and 1/2 times further than Monday's distance. This means that the distance traveled on Tuesday is 1.5 times the distance traveled on Monday.
How can we find the total distance traveled over a period of multiple days?To find the total distance traveled over a period of multiple days, we can add up the distances traveled on each day. This can be done by summing up all the individual distances traveled on each day. This can be done either in fraction or decimal. If the distances are in mixed numbers, it is good to convert them into fractions before adding them. This will give the total distance traveled over the period of multiple days.
On Tuesday, you ride 1 and 1/2 times further than on Monday, which is 3 and 2/3 miles * 1 and 1/2 = 5 and 1/2 miles.
On Wednesday, you ride 1 and 1/4 miles less than on Tuesday, which is 5 and 1/2 miles - 1 and 1/4 miles = 4 and 1/4 miles.
The total number of miles you rode on Monday, Tuesday, and Wednesday is:
3 and 2/3 miles + 5 and 1/2 miles + 4 and 1/4 miles = 13 and 5/6 miles
You can convert the mixed numbers to fraction to find the total miles.
3 and 2/3 miles = (33 + 2)/3 = 11/3 miles
5 and 1/2 miles = (52 + 1)/2 = 11/2 miles
4 and 1/4 miles = (4*4 + 1)/4 = 17/4 miles
So, the total number of miles you rode on Monday, Tuesday, and Wednesday is :
11/3 + 11/2 + 17/4 = (114 + 113 + 172)/12 = 11/3 + 33/4 = (114 + 11*3 + 34)/12 = 44/3 = 14.67 miles
You rode 14.67 miles in total for 3 days.

What is rectangle?A rectangle is a closed two-dimensional figure with four sides. The opposite sides of a rectangle are equal and parallel to each other and all the angles of a rectangle are equal to 90°.
Given,
Figure OUTD is a rectangle.
Each angle in a rectangle measures 90 degrees.
Therefore,
(7X + 2) + 4X = 90
7X + 2 + 4X = 90
11X + 2 = 90
Subtract 2 from both sides of the equation
11X = 88
Divide both sides of the equation by 11
X = 8.
Hence, 8 is the value of x.

Which value of X satisfies both -9X + 4Y = 8 and -3X - Y = 4 given the same value of Y
The value of X that satisfies both -9X + 4Y = 8 and -3X - Y = 4 given the same value of Y is X = -8/7.
What is an equation?An equation is a mathematical statement that shows that two mathematical algebraic expressions are equal. For example, x + 7 = 10 is an equation, in which x + 7 and 10 are two expressions separated by an 'equal to' sign.
An equation also has two sides, the let hand side and the right hand side.
Solving the two equations simultaneously we have:
-9x + 4y = 8 --- (1)
-3x - y = 4 --- (2)
Multiply 2 by 3 and subtract from (1) as shown below
-9x + 4y = 8
-9x - 3y = 12
------------------
0 + 7y = - 4
7y = -4
y = -4/7
Substituting the value of y in equation 2 we get the value of x.
-3x - (- 4/7) = 4
-3x + 4/7 = 4
-3x = 4 - 4/7
-3x = 24/7
x = -8/7
