coordinates of the point are (2,6) and (3,4)
Answer:
Solution given:
let the given point be A(1,8) and B(4,2).
P and Q are the two points on AB such that
AP=PQ=QB=k
now
comparing AP and PB
AP=k
PB=2k
ratio of AP and PB =\(\frac{1k}{2k}\)= ratio 1:2
now
finding p
for this
\((m_1,m_2)=(1,2)\)
For AB
\((x_1,y_1)=(1,8)\)
\((x_2,y_2)=(4,2)\)
now by using division formula
\((x,y)=(\frac{m_1x_2+m_2x_1}{m_1+m2},\frac{m_1y_2+m_2y_1}{m_1+m2})\)
\(=(\frac{1*4+2*1}{1+2},\frac{1*2+2*8}{1+2})=(2,6)\)
similarly
Q divides AB
Ratio of AQ and QB =\(\frac{2k}{1k}\)= ratio 2:1
\((x_1,y_1)=(1,8)\)
\((x_2,y_2)=(4,2)\)
\((m_1,m_2)=(2,1)\)
by using division formula
\((a,b)=(\frac{m_1x_2+m_2x_1}{m_1+m2},\frac{m_1y_2+m_2y_1}{m_1+m2})\)
\(=(\frac{2*4+1*1}{2+1},\frac{2*2+1*8}{2+1})=(3,4)\)

There are 5 full square and 6 triangles that are half squares.
5 + (6)(1/2) = 5 + 3 = 8
You could also break this into smaller shapes (like a big triangle on the top and a smaller triangle and rectangle on the bottom and use area formulas to calculate the area. But counting works well in this example.
Answer: 8
Step-by-step explanation:
First you split up this shape into two different shapes, a triangle and trapezoid
Put a line through the coordinates (-2,2) to (-1,2); the top is a triangle and the other is a trapezoid
Area of the trapezoid is A = .5x (base1 + base2) x height
base1 of the trapezoid goes from -4 to -1 which is 3
base2 goes from -2 to -1 which is 1
height is 0 to 2 whcich is 2
A = .5 x (3+1) x 2 = 4
Now area of a triangle is A = .5 x base x height
the base goes from -2 to 2 which is 4
the height goes from 2 to 4 which is 2
A = .5 x (4) x (2) = 4
Area of the Trapezoid + Area of the Triangle = Total Area
4 + 4 = 8
he lengths of the sides of a rectangle are and where the sum of the lengths of the two shorter sides and one of the longer sides of the rectangle is 36. what value of maximizes the area ofthe rectangle?
The maximum area of the rectangle is A = xy = 12 * 12 = 144 square units.
Let's assume the two shorter sides of the rectangle are x and y, where x ≤ y, and the longer side is z. According to the given information, we have the following equations:
x + y + z = 36 (Equation 1)
x ≤ y
To maximize the area of the rectangle, we need to find the maximum value of xy.
From Equation 1, we can express z as z = 36 - (x + y).
The area of the rectangle, A, is given by A = xy.
Substituting z in terms of x and y, we have:
A = xy = x(36 - (x + y)) = 36x - x² - xy (Equation 2)
To find the value of x that maximizes the area, we can differentiate Equation 2 with respect to x and set the derivative equal to zero:
dA/dx = 36 - 2x - y = 0
Since x ≤ y, we can substitute y with x in the equation above:
36 - 2x - x = 0
Simplifying the equation, we get:
36 - 3x = 0
3x = 36
x = 12
Now that we have the value of x, we can substitute it back into Equation 1 to find y:
12 + y + z = 36
y + z = 24
Since the sum of the lengths of the two shorter sides and one longer side is 36, and x = 12, we can deduce that y = 12.
Therefore, the sides of the rectangle are x = 12, y = 12, and z = 12 (since z = 36 - (x + y) = 12). This means we have a square.
In a square, all sides are equal. Therefore, the maximum area of the rectangle is obtained when all sides are equal, i.e., when x = y = z = 12.
The maximum area of the rectangle is A = xy = 12 * 12 = 144 square units.

The average person drinks 3 Liters of water when hiking the Mission Peak (with a standard deviation of 1 Liter). You are planning a hiking trip to the Mission Peak for 10 people and will bring 35 Liters of water. What is the probability that you will run out? What if the hiking trip will have 20 people and the amount of water you bring also doubles to 70 Liters. What is the probability you will run out? Please solve this problem in Excel and submit your Excel file. Will the probability of running out of water increase or decrease? Why?
The probability of running out of water decreases.
The given problem can be solved by using the concept of the normal distribution. Normal distribution, also called Gaussian distribution, is a probability distribution that occurs naturally in many situations. In this distribution, data values cluster around a central point, and the further away a value is from the center, the less likely it is to occur. The normal distribution has two parameters: the mean (μ) and the standard deviation (σ). The mean is the center of the distribution, and the standard deviation is a measure of how spread out the distribution is. The normal distribution is symmetric about the mean. It is a continuous distribution, meaning that it can take any value between negative infinity and positive infinity. The area under the normal curve represents the probability of a random variable taking a certain value or falling within a certain range of values. The total area under the normal curve is equal to 1.
Given:
The average person drinks 3 Liters of water when hiking the Mission Peak (with a standard deviation of 1 Liter).
You are planning a hiking trip to the Mission Peak for 10 people and will bring 35 Liters of water.
What is the probability that you will run out?
We need to find the probability that the amount of water consumed by 10 people will be greater than 35 Liters. Let X be the random variable representing the amount of water consumed by each person. X is normally distributed with mean μ = 3 Liters and standard deviation σ = 1 Liter.
Then, the total amount of water consumed by 10 people is given by the sum of 10 independent identically distributed (i.i.d.) random variables:
Y = X1 + X2 + ... + X10
where X1, X2, ..., X10 are i.i.d. random variables with the same distribution as X.
The total amount of water you bring is 35 Liters. Therefore, you will run out of water if:
Y > 35
or equivalently:
(Y - μ10) / σ10 > (35 - μ10) / σ10
where μ10 = 10μ = 30 Liters and σ10 = √(10)σ = √(10) Liters.
Thus, the probability that you will run out of water is:
P(Y > 35) = P[(Y - μ10) / σ10 > (35 - μ10) / σ10]
= P(Z > (35 - μ10) / σ10)
where Z is the standard normal variable.
Using the standard normal table, we find that:
P(Z > (35 - μ10) / σ10) = P(Z > (35 - 30) / √10)
= P(Z > 1.5811)
= 0.0564 (rounded to four decimal places)
Therefore, the probability that you will run out of water when hiking the Mission Peak with 10 people is 0.0564.
What if the hiking trip will have 20 people and the amount of water you bring also doubles to 70 Liters. What is the probability you will run out?
In this case, the number of people has doubled, so the total amount of water consumed will also double. Thus, the total amount of water consumed by 20 people is given by:
Y = X1 + X2 + ... + X20
where X1, X2, ..., X20 are i.i.d. random variables with the same distribution as X.
The total amount of water you bring is 70 Liters. Therefore, you will run out of water if:
Y > 70
or equivalently:
(Y - μ20) / σ20 > (70 - μ20) / σ20
where μ20 = 20μ = 60 Liters and σ20 = √(20)σ = 2.2361 Liters.
Thus, the probability that you will run out of water is:
P(Y > 70) = P[(Y - μ20) / σ20 > (70 - μ20) / σ20]
= P(Z > (70 - μ20) / σ20)
where Z is the standard normal variable.
Using the standard normal table, we find that:
P(Z > (70 - μ20) / σ20) = P(Z > (70 - 60) / 2.2361)
= P(Z > 4.4721)
= 0 (rounded to four decimal places)
Therefore, the probability that you will run out of water when hiking the Mission Peak with 20 people is zero.
Will the probability of running out of water increase or decrease? Why?
The probability of running out of water decreases when the number of people increases and the amount of water brought doubles. This is because the total amount of water consumed increases proportionally to the number of people, but the standard deviation of the distribution of the amount of water consumed decreases proportionally to the square root of the number of people. This means that the distribution of the total amount of water consumed becomes narrower and more concentrated around the mean as the number of people increases.

If you flipped two coins simultaneously, for a total of 24 times, how many times, on average, would you expect to get a head and a tail?
When two coins are flipped simultaneously 24 times, on average 12 times we will get a head and a tail.
For given question,
When two coins are tossed simultaneously, the sample space is as follows:
S = { HH, HT, TH, TT} where H denotes Head and T denotes tail.
Using the formula of probability,
P = Number of favorable outcomes/total number of outcomes,
we get,
P(HT) = 1/4
and
P(TH) = 1/4
We know that the occurrence of two mutually exclusive events is the sum of their individual probabilities.
So, P(Head on one and Tail on other)
= P(HT) + P(TH)
= 1/4 + 1/4
= 2/4
= 1/2
= 0.5
So, when two coins flipped simultaneously, the probability of flipping 2 coins and getting a head and a tail is 0.5
In this question, we need to find the number of times getting a head and a tail when two coins are flipped simultaneously 24 times
= 0.5 × 24
= 12
Therefore, When two coins are flipped simultaneously 24 times, on average 12 times we will get a head and a tail.

at old oak farm, there are chicken and horses. there are 120 legs and 48 heads altogether. how many horses and how many chickens are there?
Answer:
Step-by-step explanation:
We must use system of equations:
horses = h chickens = c
horses have 4 legs & chickens have 2 and there are 120 legs total so to set up the first part of the equation...
4h + 2c = 120
They both have only 1 head each and there are 48 heads total so to set up the second part of the equation...
h + c = 48
Now we combine the equations and solve:
4h + 2c = 120
h + c = 48
Now we solve...
4h + 2c = 120
h = 48 - c (subtract c on both sides to single out h)
--------------------
4(48 - c) + 2c = 120
192 - 4c + 2c = 120
-192 -192
----------------------------
-2c = -72 (divide both sides by -2)
c = 36
Now we go back and find the value of h...
h = 48 - c
h = 48 - 36
h = 12
So there are 36 chickens & 12 horses!
