Determine the theoretical probability of rolling a number larger than 3 on a standard 6-sided cube. 1/2, 1/6, 1/4, 1/3
Answer:
Option A is correct.
Step-by-step explanation:
Given: A 6-sided cube is rolled.
To find: Probability of getting a number greater than 3.
Total number of outcome when a 6-sided cube is rolled = 6
Favorable outcome = { 4 , 5 6 }
Number of favorable outcome = 3
Theoretical Probability is a probability based on reasoning written as a ratio of the number of favorable outcomes to the number of possible outcomes.
[tex]Probability=\frac{Number\:of\:favorable\:outcome}{Number\:of\:Total\:outcome}[/tex]
[tex]Probability=\frac{3}{6}=\frac{1}{2}[/tex]
Therefore, Option A is correct.

If a point is equidistant from the two sides of an angle, then it is:
A. on the perpendicular bisector.
B. the vertex of the angle.
C. on the angle bisector.
D. on one side of the angle.
A point is equidistant from the two sides of an angle, then it is option (C) on the angle bisector is the correct answer.
What is angle bisector theorem?An angle bisector is a straight line drawn from the vertex of a triangle to its opposite side in such a way, that it divides the angle into two equal or congruent angles.
For the given situation,
Any point that is on the angle bisector is an equal distance ("equidistant") from the two sides of the angle.
A point which is always equidistant from all the sides is the point of intersection of internal angle bisectors.
Hence we can conclude that a point is equidistant from the two sides of an angle, then it is option (C) on the angle bisector is the correct answer.

4a=2b-7 solve for b
anyone know how to do this?
Final answer:
To solve for b in the equation 4a = 2b - 7, you need to add 7 to both sides and then divide by 2. The solution is b = (4a + 7)/2.
Explanation:
To solve the equation 4a = 2b - 7 for b, you want to isolate b on one side of the equation. This means we need to perform operations that will move all other terms away from b.
First, let's add 7 to both sides of the equation to get rid of the -7 that's subtracted from b:
4a + 7 = 2b
Next, we will divide both sides of the equation by 2 to solve for b:
(4a + 7)/2 = b
So, b equals to the expression (4a + 7)/2.

how tall is a person whose arm span is 66 inches? What is the arm span of a 74-inch-tall person?
The arm span of 74- inch tall person is 74 inches and height of person with 66 inches arm span is 66 inch.
What is arm span?Your arm span is the distance between the middle fingertips on each hand when you stretch your arms out as far as they can reach.
arm span= 66 inches
As, height of person= 74 inch
The person who is having 66inch arm span also being 66inches in height,
which means the if the arm span is of the 74inch
then man would also be 74inch arm span
This is because your arm span equals your height.

Final answer:
A person with an arm span of 66 inches is likely to be about 66 inches tall, and a 74-inch-tall person likely has an arm span of about 74 inches. The height in meters of a person who is 6 feet 1.0 inch tall is about 1.8542 meters.
Explanation:
Understanding Arm Span and Height Relationships
The relationship between arm span and height is interesting as they tend to be about the same for an individual. For a person with an arm span of 66 inches, we can estimate that the person's height is approximately the same, around 66 inches. However, this relationship can vary slightly based on individual proportions.
Conversion between Inches and Meters
To convert a person's height from feet and inches to meters, we use the conversion factor 1 meter equals 39.37 inches. For a person who is 6 feet 1.0 inch tall (which equals 73 inches in total), their height in meters would be:
Height in meters = (73 inches) / (39.37 inches per meter) = 1.8542 meters (rounded to four decimal places).
Estimates Based on Anthropometric Data
The arm span of a 74-inch-tall person would again typically be close to their height, so around 74 inches. These estimates are part of anthropometric data, which helps in understanding human body measurements in various fields, including ergonomics, clothing design, and health assessments.
Solve for t: d = rt
t = dr
t = r/d
t = d/r
t = d + r
Answer:
t = d/r
Step-by-step explanation:
In order to solve an equation for another term from which is initally solved by another term you just have to leave the term you want to solve the equation for, in this case the "t" and to do so since in this formula it is multiplying the "r" we haec to divide both sides of the equation by "r":
[tex]d=rt[/tex]
[tex]\frac{d}{r} =\frac{rt}{r}[/tex]
Now we eliminate the since they are in both sides of the fraction:
[tex]\frac{d}{r} =\frac{rt}{r}[/tex]
And the function is solved for t.
