3Justin's estimated Vo2 max is 25.8(mL*kg*min)
What is Vo2 max ?
The amount (volume) of oxygen used by your body while exercising as hard as you can is referred to as VO2 max. It's a common tool for determining your level of fitness. Knowing your VO2 max can assist you in training for sports, tracking fitness progress, and improving your heart health.
Here using vo2 max fomula 1.5 miles ,
=> VO2 max = 3.5+483/Time
Here Time= 11 min 25 sec = 25/60 = 0.41 min
Then time=11.42 mins. Now,
=> VO2 max = 3.5+ 483/11.41
=> VO2 max = 3.5+42.3
=>VO2 max = 25.8(mL*kg*min)
Hence His estimated Vo2 max is 25.8(mL*kg*min)

A swimming pool is draining at a constant rate.
The table shows the proportional relationship between
the change in the water level and the number of hours
the pool has drained. Complete the table to show the change
in water level at 9 and 23 hours?
The level of water in the swimming pool after a specified duration of the water draining at a constant rate is found as follows;
10. a. The water level is changing (reducing) at a rate of 1.75 inches per hour.
b. After 9 hours, the change in the water ls 15.75 inches
c. The change in the water level after 23 hours is 40.25 inches
What is a constant rate?A constant rate is a rate that is fixed or steady and does not vary following a change of the other variables?
The table of values for the draining swimming pool obtained from a similar question on the internet is as follows;
Hours Draining [tex]{}[/tex] Change in Water Level (inches)
2 [tex]{}[/tex] -35
9 [tex]{}[/tex] ?
17 [tex]{}[/tex] -29.75
23 [tex]{}[/tex] ?
The relationship between the hours the swimming pool drains and the water level is a proportional relationship., such that the ratio of each coordinate pair in the table is a constant.
Let H represent the hours draining and let C represent the change in water level, we have;
C ∝ H
C = k·H
[tex]k = \dfrac{C}{H}[/tex]
Where;
k = The constant of proportionality, which is the rate at which the water level is changing per hour
a. The rate at which the water level changes per hour can be found from the first pair of points on the table as follows;
The first pair of points = (2, -3.5)
[tex]k = \dfrac{-3.5}{2} = -1.75[/tex]
The rate at which the water level is changing per hour is -1.75 inches per hour
The water level is decreasing at 1.75 inches per hour
b. The change in water level after 9 hours is found by using the formula;
C = k × H
Where, H = 9, we have;
Change in water level, C = -1.75 × 9 = -15.75
The change in water level after 9 hours is 15.75 inches
c. The change in water level after 23 hours is found by plugging in H = 23 as follows;
C = -1.75 × 23 = -40.25
The change in water level after 23 hours is -40.25 inches

Finding a Missing Endpoint
The new x-coordinate must be 2-2 = 0.
What are endpoints?Many objects in geometry such as line segments, angles, polygons, etc., can be named using endpoints:Points A and B are endpoints for the line segment below. The line segment is named by its endpoints, AB or BA.A ray on the other hand, has only one endpoint as shown below. The ray is named using its endpoint as the first letter, AB.An angle can be named using the common endpoint of the two rays, as shown below. Rays AB and BC share endpoint B and form an angle. This angle can be named as ∠ABC or, using just its endpoint, as ∠B.acc to our question-
Finding the distance between the known endpoint and the midpoint, then applying the same transformation to the midpoint, is the quickest technique to locate the missing endpoint. The x-coordinate changes in this situation from 4 to 2, or down by 2, hence the new x-coordinate is 2-2 = 0.
Hence,The new x-coordinate must be = 0.

Two cards are drawn without replacement from an ordinary deck. Find the probability that the second is not a red card, given that the first is not a red card.
What is the conditional probability?
Is it possible to apply the conditional probability in its alternative form, P(R2|R1) is n(R1⋂R2) divided n(R1) Given that the product rule hasn't yet been taught, we have advocated this approach.
What is the likelihood of receiving two red cards without being replaced?The probability of drawing a second red in the event that this red is not changed is 9/15,
hence the probability of A is 10/16 * 9/15, or 0.375.
The potential of an event or outcome occurring based on the existence of a prior event or outcome is known as conditional probability. It is determined by multiplying the likelihood of the earlier occurrence by the increased likelihood of the later, or conditional, event.Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.Is it possible to apply the conditional probability in its alternative form, P(R2|R1) is n(R1⋂R2) divided n(R1) Given that the product rule hasn't yet been taught, we have advocated this approach.To learn more about conditional probability refer to:

7x=8x+12
How do I solve this
Answer:
x = -12
Step-by-step explanation:
Get X all on one side
7x - 8x = 8x - 8x + 12
-x = 12
x = -12
Answer:
x = -12
Step-by-step explanation:
To solve this, you will need to get all of the variables on one side, and the 12 on the other. You will subtract 8x from both sides to get the equation -x = 12. You can then divide both sides by -1 to get the x alone, and thus you get x = -12.
3 exponet 4 x (20.3 - 9) + 14.5
The solution to the expression is given as 3 exponent 4 x (20.3 - 9) + 14.5 is 929.8
How to determine solution to the expression?From the question, the expression is given as
3 exponent 4 x (20.3 - 9) + 14.5
When the expression is rewritten, we have the following representation
3⁴ x (20.3 - 9) + 14.5
Evaluate the exponent
So, we have
3⁴ x (20.3 - 9) + 14.5 = 81 x (20.3 - 9) + 14.5
Evaluate the expression in the bracket
3⁴ x (20.3 - 9) + 14.5 = 81 x 11.3 + 14.5
Solving further, we have
3⁴ x (20.3 - 9) + 14.5 = 915.3 + 14.5
Lastly, we have
3⁴ x (20.3 - 9) + 14.5 = 929.8

sophie's favorite number is a two-digit number. if she reverses the digits, the result is $45$ less than her favorite number. the sum of the digits in her favorite number is $11$. what is sophie's favorite number?
Sophie's favorite number is 83
We have that;
A two-digit number is Sophie's preferred number. Her favorite number is 45 less when the digits are in reverse. Her favorite number has digits that add out to 11 in total.
To get Sophie's favorite number, we need to assume the case as;
Let,
⇒10x + y = 10y + x + 45
x + y = 11
y = 11-x
⇒10x + 11 - x = 10(11 - x) + x + 45
10x + 11 - x = 110 - 10x + x + 45
9x + 11 = 155 - 9x
18x + 11 = 155
18x = 144
x = 8

The probability that 2 red cards and 11 black cards are dealt is .
What is probability ?The probability of an event is given by dividing the favorable outcomes by total number of outcomes. The sum of all the probabilities of events is always 1. If for finding probability we have to select r out of n. Combination is used to select r items out of n, the formula is as follows,

It is known as an intersection of lines when two lines have exactly one point in common. A point is shared by the connecting lines. The point of intersection is the same place that may be found at the intersection of all intersecting lines. When two or more straight lines cross each other in a plane, they are said to be intersecting lines. An intersection point will be present for the two non-parallel straight lines that are coplanar.

The solution to the expression given as 5x + 3y > 12 has the ordered pair of (3, 0)
How to determine the ordered pair of the solution?From the question, we have the following inequality that can be used in our computation:
5x + 3y > 12
Solving further, we need to collect the like terms
So, the expression becomes
3y > 12 - 5x
Next, we divide through the inequality by 3
So, we have the following representation
y > 12/3 - 5/3x
Evaluate
The equation becomes
y > 4 - 5/3x
At this point, we assume any value for x and then solve for y
Assume that the value of x is 3
So, we have the following representation
y > 4 - 5/3 * 3
Evaluate the products
y > -1
A value greater than -1 is 0
So, we have
x = 3 and y = 0
Express as ordered pairs
(x, y) = (3, 0)
Hence, the ordered pair of the solution is (3, 0)

Given that the dimensions of solid box is 15 cm by 10 cm by 8 cm.
So the volume of solid box = 15*10*8 cubic cm = 1200 cubic centimeter
The volume of the cube with side 3 cm = 3*3*3 = 27 cubic centimeter
For each corner one cube so the number of cube is 4
