(a)let A=event that first k-1 draws will get r-1 red balls
let B=event that last (kth) draw will get rth red ball
P(kth draw is the rth red ball)= P(A AND B) = P(A)xP(B)
(b)P(A)= # of ways to draw r-1 red balls in k-1 trail
# of ways to draw k-1 balls
RBBB *R is one way to achieve P(A AND B)
BBBR *R is another way.
(c)There are n−(r−1) red left, and a total of (m+n)−(k−1) balls left, so the (conditional) probability of drawing a red on the kth trial is n−r+1/m+n−k+1 Thus our required probability is
So, P(A)= nC(r-1) x mC(n-r) x 1/(n+m)C(k-1)

Daniel went hiking. He began his hike at an altitude of 120 feet. He climbed at a rate of 25 feet every half hour. What is Daniel’s Altitude after 6 hours of hiking?
Answer:
420 feet.
Step-by-step explanation:
We have to first multiply 25 times 12 (because 6 hours is 12 half hours) which is 300.
300 plus his starting point, 120 is 420.
Therefore, your answer is 420 feet.
Answer: 420 feet
Step-by-step explanation:
Because Daniel climbed 25 feet every half hour for 6 hours, 25 feet is added 12 times to the 120 feet he already climbed.
120 + (25 × 12)
25 × 12 = 300
120 + 150 = 420

In this question, we need to calculate the total cost of the recipe by finding the total cost of each of the ingredients and adding them all together.
The ingredients amount in converted units
ep amount conversion unit cost ($/unit)
leeks 4 oz 0.25 lb 3.00/lb

butter 1 oz 0.0625 lb 3.00/lb
spinach 8 oz 0.5 lb 2.25/lb
eggs 6 ea 0.5 dozen 2.75/dozen
First, we have to determine to total cost per ingredient.
1. 0.25 x 3.00 = $0.75 (leeks)
2. 0.625 x 2.85 = $1.78125 (yellow squash)
3. 0.0625 x 3.00 = $0.1875 (butter)
4. 0.5 x 2.25 = $1.125 (spinach)
5. 0.5 x 2.75 = $1.375 (eggs)
Now, we can add the cost per ingredient to know the total cost.
$0.75 + $1.78125 + $0.1875 + $1.125 + $1.375
= $5.21875

The length of a rectangle is 11 ft more than double the width, and the area of the rectangle is 63 ft². Find the dimensions of the rectangle
The dimensions of the rectangle is 18 ft by 3.5 ft.
What is the dimension of a 2D objects?
Geometrically speaking, 2-dimensional shapes or objects are flat planar figures with two dimensions—length and width. Shapes that are two-dimensional, or 2-D, have only two faces and no thickness. Two-dimensional objects include a triangle, circle, rectangle, and square.
Assume that the width of the rectangle is w.
Given that, the length of a rectangle is 11 ft more than double the width.
The length of the rectangle is (2w + 11) ft.
The area of the rectangle is (2w + 11) w = 2w² + 11w.
Also given the area of the rectangle is 63 ft².
Therefore,
2w² + 11w = 63
2w² + 11w - 63 = 0
Now applying quadric formula:
w = (-11 ± √{(-11)² -(4 × 2 × (-63))})/(2 × 2)
w = -9, 3.5
Since the length of the rectangle can't be negative, thus w ≠ -9.
w = 3.5
The length of the rectangle is (2 × 3.5 + 11) = 18 ft.

The gravitational force is a force that attracts any two objects with mass. We call the gravitational force. It is given by, F=Gm1m2r2, direction of force will be always towards the other mass along the line joining the two bodies. It is attractive force in nature.
Gravity
The force of attraction by which terrestrial bodies tend to fall toward the center of the earth. heaviness or weight. gravitation in general.
The acceleration due to gravity of a planet with mass M and radius R is g as:
free-fall acceleration = 12.25 m/s²
Formula for free fall acceleration is given by the gravity equation;
g = Gm/r²
Where;
M is mass of the Earth
r is radius of the Earth
G is the gravitational constant
That equation applies to the earth.
For this new planet, that the mass = 5 × mass of earth
And radius = 2 × radius of earth.
Thus, free fall acceleration for this planet is;
g_ p = G(5m)/(2r)²
g_ p = (5/4)(Gm/r²)
Gravitational constant has a value of 6.674 × 10^(−11) N.m²/kg²
Mass of the earth = 5.972 × 10^(24) kg
Radius of the earth = 6378 km = 6378000
Thus
g_ p = (5/4)(6.674 × 10^(−11) × 5.972 × 10^(24))/(6378000²) = 12.25 m/s²

find four consecutive even integers such that the sum of the first three exceeds the fourth by 8.
Answer:
4, 6, 8, 10
Step-by-step explanation:
consecutive even integers have a difference of 2 between them.
let the 4 consecutive even integers be
n , n + 2 , n + 4 , n + 6 , then
n + n + 2 + n + 4 = n + 6 + 8
3n + 6 = n + 14 ( subtract n from both sides )
2n + 6 = 14 ( subtract 6 from both sides )
2n = 8 ( divide both sides by 2 )
n = 4
n + 2 = 4 + 2 = 6
n + 4 = 4 + 4 = 8
n + 6 = 4 + 6 = 10
the 4 integers are 4 , 6 , 8 , 10

Therefore , the Pedro's car speed is 2 times the Juan car speed.
Define the speed.Speed is a measure of how fast something or an individual is moving. It is possible to determine an object's average speed if you are aware of how far it has come and how the time it took to get there. Speed is determined by the formula: speed = distance * time.
Here,
Juan car travels 15 m/s
Where as Pedro's car travels 150 meters in 5 seconds.
Thus,
Pedro car speed is

A = πr² ( r is the radius)
to calculate the area we require to know r
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²

Compound interest is calculated as a sum using the interest and principal accrued over time. Compound interest versus simple interest differ primarily in this way.
As per the given information in the question,
The account in this issue is split up into two distinct investments. The first one is for $12,000 with a 12% compound interest rate over six years. Consequently, the criteria are as follows:

in the context of assessing wound healing as an indicator of immune functioning, which of the following impairs the inflammatory response that initiates wound repair?
Acute ethanol exposure can hinder the early inflammatory response, which can delay wound healing.
Hemostasis, inflammation, proliferation, and remodeling are the four perfectly timed steps that make up the normal biological process of wound healing in the human body. All four phases of wound healing must take place in the right order and amount of time for healing to be successful. Numerous factors may affect one or more stages of this procedure, impairing or causing incorrect wound healing.
Each stage of wound healing has certain milestones that must occur in order for normal healing to progress. In order to identify the differences inherent in chronic wounds that prevent healing, it is important to review the process of healing in normal wounds
