Kelly can run 1/2 mile in 3 minutes. 1/6 mile Kelly run in 1 minute if he runs at the same pace the entire time.
What makes anything a mile?The word "mile" is derived from the Latin "mille passus," which means "one thousand paces." The English Parliament established the Mile at eight furlongs (one furlong is 660 feet) in 1592. A mile is a unit of measurement that is standardised as exactly 1609.344 metres by the International agreement in 1959. A mile is exactly equivalent to 5280 feet, or 1760 yards.
Kelly can run 1/2 mile in 3 minutes so the ratio is 1/2 mile per 3 minutes
= [tex]\frac{\frac{1}{2} }{3}[/tex]
For transforming 3 to 1 we need to divide by 3 because we have to keep the ratio value, we have to divide also the numerator by 3 :
= [tex]\frac{\frac{1}{2} }{3} \times \frac{\frac{1}{3} }{\frac{1}{3}}[/tex]
[tex]= \frac{\frac{1}{2} \times \frac{1}{3} }{3 \times \frac{1}{3} }[/tex]

In a plane, lines that are parallel to one another do not meet or overlap at any point. They are always parallel and equally spaced apart. Parallel lines are non-intersecting lines. Infinity is another place where parallel lines are believed to meet.
We are given a set of parallel lines and various angles are marked on the lines.
Angles 3 and 4 can not prove that the lines are parallel because they lie on the same line.
Similarly, angles 7 and 8 can also not prove.
But, angles 3 and 5 can prove this because they lie on different lines i.e. they belong to both the lines.

if f(x) is discontinuous, determine the reason. f of x equals the quantity x squared plus 4 for x less than 1 and equals x plus 4 for x greater than 1
The two equations for f(x) are not equal at x = 1 and f(x) is therefore discontinuous at this point
f(x) is discontinuous at x = 1 because when x = 1, the two separate equations for f(x) do not have the same output. For x < 1, [tex]f(x) = x^2 + 4[/tex], so when x = 1, [tex]f(1) = 1^2 + 4 = 5. For x > 1, f(x) = x + 4[/tex] , so when x = 1, f(1) = 1 + 4 = 5. The output of f(1) is different on each side of the discontinuity. This can be seen in the following calculation:
For x < 1,
[tex]f(x) = x^2 + 4f(1) = 1^2 + 4 = 5For x > 1,f(x) = x + 4f(1) = 1 + 4 = 5[/tex]
Since f(1) is 5 for x < 1 and f(1) is also 5 for x > 1, the two equations for f(x) are not equal at x = 1 and f(x) is therefore discontinuous at this point.

y = 2x + 3
y = 8/4 x - 1/4
how many solutions
Answer: The number of solutions for the system of linear equations depends on whether the lines are parallel or intersect at a single point. If the lines are parallel, there are no solutions, as they never meet. If the lines intersect at a single point, there is exactly one solution.
To determine the number of solutions, we need to find the point of intersection of the two lines. We can do this by solving for x in one equation and substituting it into the other equation:
2x + 3 = 8/4 x - 1/4
8x + 12 = 2x - 1/2
6x = - 12.5
x = -2.08
Then, substituting this value of x back into either equation to find the corresponding value of y:
y = 2 * (-2.08) + 3 = 0.16
So, the two lines intersect at the point (-2.08, 0.16), which means there is exactly one solution to the system of linear equations.

let y1,y2 be independent random variables both having the uniform(0,1) distribution. re- call that the density function and distribution function of a uniform random variable y
A uniform random variable's density function is f(y) = 1 for y 1 and 0 otherwise. F(y) = 0 for y 0, F(y) = y for 0 y 1, and F(y) = 1 for y > 1 define the distribution function.
A uniform random variable's density function is f(y) = 1 for y 1 and 0 otherwise. Accordingly, the likelihood of any specific outcome of y is the same, and the likelihood of any range of outcomes is equal to the length of the range. F(y) = 0 for y 0, F(y) = y for 0 y 1, and F(y) = 1 for y > 1 define the distribution function. Accordingly, the length of the range multiplied by the likelihood of any specific occurrence yields the cumulative probability of any range of outcomes. Since the likelihood of any specific result in that range is 1 and the range's length is 0.5, for instance, the cumulative probability of 0 y 0.5 is 0.5. Since the likelihood of any given result within that range is still 1, but the range's length is 0.5, the cumulative probability of 0.5 y 1 is 0.75. The chance of any range of outcomes for y1 and y2 if they are independent random variables both having the uniform(0,1) distribution is just the sum of their respective cumulative probabilities.

The radius of a circle is 4.5 cm.find the circumference to the nearest tenth
Answer:
28.26cm
Step-by-step explanation:
The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle.
Plugging in r = 4.5 cm, we get:
C = 2π * 4.5 = 9π cm
To find the value of C to the nearest tenth, we can approximate π to 3.14:
C = 9 * 3.14 = 28.26 cm
determine the solutions of the equation: the absolute value quantity four thirds times x plus 2 end quantity minus 6 equals 0
the solutions of the equation are x = -1.5 and x = 2.
The solutions of the equation are x = -1.5 and x = 2.
Absolute value equation: |4/3x + 2| - 6 = 0
Equation inside absolute value must equal 0:
4/3x + 2 - 6 = 0
4/3x = -4
x = -4 * (3/4)
x = -1.5
Equation inside absolute value must equal 0:
4/3x + 2 + 6 = 0
4/3x = -8
x = -8 * (3/4)
x = 2
The absolute value quantity of four thirds times x plus 2 end quantity minus six equals zero can be written as:
|4/3x + 2| - 6 = 0
This equation can be rewritten as two separate equations as follows:
4/3x + 2 - 6 = 0
4/3x + 2 + 6 = 0
Solving the first equation:
4/3x + 2 - 6 = 0
4/3x = -4
x = -4 * (3/4)
x = -1.5
Solving the second equation:
4/3x + 2 + 6 = 0
4/3x = -8
x = -8 * (3/4)
x = 2
Therefore, the solutions of the equation are x = -1.5 and x = 2.

What is probability?
Probability is a mathematical concept used to determine the likelihood of an event. It merely allows us to calculate the probability or possibility that an event will occur. The range of probabilities lies between 0 and 1, where 1 signifies a certain event and 0 denotes an impossibility.
We are given the following:
No. of students that have taken a distance learning class = 8%
No. of students that are part-time students = 30%
No. of part-time students that have taken a distance learning class = 20%
Let D = event that a student takes a distance learning class and E = event that a student is a part-time student.
(a) Since, 20% of the part times students are taking distance learning classes (D and E) so,
P(D and E) = 0.3 * 0.2 = 0.06
(b) P (E | D) = P (D and E) / P (D)
P (E | D) = 0.06 / 0.08
P (E | D) = 0.75
(c) P (D or E) = 0.3 + 0.08 - 0.06 = 0.32
(d) For events to be independent, probability of D and E must be equal to P(D) x P(E).
But, P(D and E) ≠ P(D) x P(E)
So, D and E are not independent.
(e) Events are considered mutually exclusive if they do not occur at the same time.
But, D and E can occur at the same time.
So, D and E are not mutually exclusive.
Hence, the solutions have been obtained.
