a die is rolled twice. what is the probability of showing a 5 on the first roll and an even number on the second roll? write your answer as a simplified fraction
The likelihood of showing a 5 on the principal roll and a significantly number on the second roll when a kick the bucket is moved two times is 1/12, which is an improved on part.
Define the term fraction?A division is a numerical articulation that addresses a piece of an entirety. It is made up of two numbers that are separated by a horizontal or diagonal line. The number below the line is referred to as the denominator, and the number above the line is referred to as the numerator.
When a fair die is rolled, there are six equally likely outcomes: 1, 2, 3, 4, 5, or 6.
The probability of rolling a 5 on the first roll is 1/6, since there is only one way to roll a 5 out of six possible outcomes.
The probability of rolling an even number on the second roll is 3/6, since there are three even numbers (2, 4, and 6) out of six possible outcomes.
We multiply the probabilities of each event to determine the probability that both will occur:
P(rolling a 5 on the first roll and an even number on the second roll) = P(rolling a 5 on the first roll) × P(rolling an even number on the second roll)
= (1/6) x (3/6)
= 1/12
Subsequently, the likelihood of showing a 5 on the main roll and a significantly number on the second roll when a bite the dust is moved two times is 1/12, which is an improved on division.

scores on the act college entrance exam follow a bell-shaped distribution with mean 21 and standard deviation 5. wayne’s standardized score on the act was −0.6 . what was wayne’s actual act score?
Wayne's Actual ACT score is 19.2 where mean is 21, standard deviation is 5 and the Z - score is -0.6.
Standard Deviation:
Standard deviation is a measure of the dispersion of a set of numerical values from their mean.
The general form of the standard deviation is,
\(SD=\sqrt{\frac{\sum (x_i-\bar{x})}{n} }\)
where
xi is each value in the data set,
x-bar is the mean, and
n is the number of values in the data set.
Given,
Mean = 21.
Standard deviation = 5
Wayne's standardized score on the act = −0.6 .
Here we need to find the Wayne's Actual ACT score.
Let x be the Wayne's Actual ACT score.
So,
=> z-score = (x - mean)/SD
Apply the values on it,
=> -0.6 = (x - 21) / 3
=> -1.8 = x - 21
=> x = 21 - 1.8
=> x = 19.2
Therefore, Wayne's Actual ACT score is 19.2

and chairs cost $40. There are 8 times as many chairs as tables. How many tables and chairs will
the school purchase for the cafeteria?
Answer:
10 tables and 80 chairs
Step-by-step explanation:
In each table, there are 8 chairs. 8×40$ =320$
1 table cost 200$
Each set of table + chairs is
200 + 320= 520
Total amount of money the school can spend is 5200
Therefore 5200÷ 520 = 10
So there are 10 sets of Table + chairs
So there are 10 tables
Total amount of chairs is 8×10= 80

Since P is a point of tangency of the circumference O, then the angle OPQ is a right angle.
Then, the triangle OPQ is a right triangle. Use the Pythagorean Theorem to write an equation for r. Then, solve that equation.
Since OQ is the hypotenuse of OPQ, then:
\(OP^2+PQ^2=OQ^2\)Since OP=r, OQ=r+9 and PQ=15, then:
\(r^2+15^2=(r+9)^2\)Expand the quadratic binomial on the right member of the equation:
\(\Rightarrow r^2+15^2=r^2+2\cdot r\cdot9+9^2\)Since the term r^2 appears on both sides, simplify the equation:
\(\Rightarrow15^2=2\cdot r\cdot9+9^2\)Simplify all terms and solve for r:
\(\begin{gathered} \Rightarrow225=18r+81 \\ \Rightarrow225-81=18r \\ \Rightarrow144=18r \\ \Rightarrow\frac{144}{18}=r \\ \Rightarrow8=r \end{gathered}\)Therefore, the radius of the circumference is:

b. unit
c. bunch
d. block
The term that describes a group of statements that executes as a single unit is a "block". A block of code is a program that is grouped together and treated as a single unit. So, the correct option is D.
In computer programming, a block is a group of statements or declarations that are enclosed within a set of curly braces ({ }). The block serves as a single unit that is executed together. Blocks are used to organize code and to apply control structures, such as loops and conditional statements, to multiple statements.
A block can contain any number of statements, which can include variable declarations, function calls, loops, conditional statements, and other constructs. The statements within a block are executed in sequence, one after another, unless a control statement is encountered that alters the normal sequence of execution.
For example, a while loop in Java consists of a block of code that is executed repeatedly while a certain condition is true:
while (condition) {
// block of code to be executed while condition is true
}
In this example, the block of code inside the curly braces will be executed repeatedly while the condition specified in the while statement is true. The block can contain any number of statements, and these statements will be executed each time the loop iterates.
Another common use of blocks is to define functions or methods. A function or method is a block of code that can be called from other parts of the program, and can take inputs (arguments) and return outputs. For example, in Python, a function can be defined as follows:
def function(argument1, argument2):
# block of code to be executed in the function
return result
In this example, the block of code enclosed within the function definition is executed when the function is called. The function can take inputs (argument1 and argument2), which can be used within the function, and it can return a result using the return statement.

A small box of cereal contains 12 23 cups of cereal. How many 1 13 cup servings are in the box?
Hi i can help!
Answer there would be 9 and 1/2 servings in the box of cereal
Step-by-step explanation:
You need to divide the total amount of cereal in the box by serving size. This would be 12 2/3 divided by 1 1/3
We can write each mixed number as an improper fraction first before we divide 12 2/3 = 38/3 and 1 1/3 = 4/3
Now divide 38/3 bye 4/3. Recall that dividing by a fraction is accomplished by multiplying by the reciprocal of the divisor: 38/3 * 3/4 = 114/12 = 38/4 OR 19/2 Also 19/2 is equivalent to 9 and 1/2.

To obtain the equation of the line that passes through these points, you can first obtain the slope of the line, using the formula
\(\begin{gathered} m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \text{ Where m is the slope of the line and} \\ (x_1,y_1),(x_2,y_2)\text{ are two points through which the line passes} \end{gathered}\)And then use the point-slope formula
\(y-y_1=m(x-x_1)\)So, in this case, you have
\(\begin{gathered} (x_1,y_1)=(3,1) \\ (x_2,y_2)=(6,6) \end{gathered}\)\(\begin{gathered} m=\frac{6-1}{6-3} \\ m=\frac{5}{3} \end{gathered}\)Now using the point-slope formula
\(\begin{gathered} y-y_1=m(x-x_1) \\ y-1=\frac{5}{3}(x-3) \end{gathered}\)Therefore, the correct answer is D.

a. Statement and Proof of Fermat's Little Theorem:
Fermat's Little Theorem concerns primes and integers in number theory.
Fermat's Little Theorem asserts that when a positive integer a, which is not divisible by a prime number p, is raised to the power of (p-1), the resultant remainder upon division by p will be 1.
So it will be: \(\\ a ^(^p^-^1) = 1 (mod p)\)
What is Fermat's Little TheoremThe Evidence has been gathered to substantiate this claim is:
In order to demonstrate the validity of Fermat's Little Theorem, we will examine a scenarios: one where a is divisible by p and the other where a is not divisible by p.If a is divisible by p, then a can be written as the product of p and a positive integer k. Expressing the value of a to the power of p minus one in relation to k and p can be achieved through utilization of the equation (k multiplied by p) raised to the power of p minus one.
By performing a simplification of the given expression, we can obtain the outcome where "a" to the power of "p" minus one is equivalent to "k" to the power of "p" minus one times "p" to the power of "p" minus one.

There are Killing vectors associated with time invariance and angular momen- tum invariance in the direction in this geometry leading to the conserved quantities e = (1-2) and l= r² sin² 0 dr From this one can derive an analog to the radial energy equation in Newtonian mechanics by orienting the coordinates so that the orbits are confined to the equatorial plane where 0 = π/2 and u = 0. One finds 2 1 dr + Veff (r) = E 2 dr (e²_ -1) where E = and Veft(r) = - + 2/²/²2 - Mp³². Further, for circular orbits one can show that M | [₁ + √/₁−12 (+1)]. r+= | 2M Finally, for circular orbits of radius R do 1/2 M dt R³ (a) Which value of r corresponds to the Schwarzschild radius of stable circular orbits: r or r?

Use the equivalence principle to argue that the period as measured at infinity should be larger than that measured by the particle. [4 marks] (d) Find the period of the orbit as measured by an observer at infinity. Find the period of the orbit as measured by the particle. [7 marks] M
(A) Circular orbits of stable particles are possible at radii greater than three times the Schwarzschild radius for the non-rotating spherically symmetric mass.
This represents the radius of a black hole's event horizon, within which nothing can escape. The Schwarzschild radius is the event horizon radius of a black hole with mass M.
M can be calculated using the formula: r+ = 2Mwhere r+ is the radius of the event horizon.
(B) 1/2 M -1/2 3M (²) ¹² (1-³) dT = R³ R. This is the required expression.
Tau is the proper time of the particle moving around a circular orbit. Hence, by making use of the formula given above:1/2 M -1/2 3M (²) ¹² (1-³) dT = R³ dt.
(C) Time passes differently in different gravitational fields, and it follows that the period as measured at infinity should be larger than that measured by the particle.
The principle of equivalence can be defined as the connection between gravitational forces and the forces we observe in non-inertial frames of reference. It's basically the idea that an accelerating reference frame feels identical to a gravitational force.
(D) The period of the orbit as measured by an observer at infinity is 16π M^(1/2) and the period of the orbit as measured by the particle is 16π M^(1/2)(1 + 9/64 M²).
The period of orbit as measured by an observer at infinity can be calculated using the formula: T = 2π R³/2/√(M). Substitute the given values in the above formula: T = 2π (8M)³/2/√(M)= 16π M^(1/2).The period of the orbit as measured by the particle can be calculated using the formula: T = 2π R/√(1-3M/R).
Substitute the given values in the above formula: T = 2π (8M)/√(1-3M/(8M))= 16π M^(1/2)(1 + 9/64 M²).
