Module 07: Project Option 1
Instructions
In this experiment, you will be using two coins as a simulation for a real-world compound event.
Suppose that a family has an equally likely chance of having a cat or a dog. If they have two pets, they could have 1 dog and 1 cat, they could have 2 dogs, or they could have 2 cats.
1. What is the theoretical probability that the family has two dogs or two cats?
A dog or a cat will have a 50/50 chance of being adopted. There are three options: 50 percent for one dog and one cat, 25 percent for two dogs, and 25 percent for two cats. Adding the probabilities of finding two of the same dogs gives you a 50 percent shot.
2. Describe how to use two coins to simulate which two pets the family has.
You will have two fair sided coins if you used two coins to simulate the potential results of the family's dogs. Each coin will have one side with a dog and one with a cat (or heads and tails, where you would assign each pet a side of the coin).
3. Flip both coins 50 times and record your data in a table like the one below.
Result Frequency
Heads, Heads 15
Heads, Tails 9
Tails, Heads 19
Tails, Tails 7
Total 50
4. Based on your data, what is the experimental probability that the family has two dogs or two cats?
22/50.
5. If the family has three pets, what is the theoretical probability that they have three dogs or three cats?
50%.
6. How could you change the simulation to generate data for three pets?
You could add another coin.

The probability of the family having two dogs or two cats is 1/2 or 50%.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The theoretical probability of the family having two dogs or two cats can be calculated as follows:
P(D) be the probability of having a dog
P(C) be the probability of having a cat.
Since the family has an equally likely chance of having a cat or a dog, we have:
P(D) = 1/2 and P(C) = 1/2
The probability of having 2 dogs is:
P(D) x P(D) = (1/2) x (1/2) = 1/4
The probability of having 2 cats is:
P(C) x P(C) = (1/2) x (1/2) = 1/4
The theoretical probability of the family having two dogs or two cats is:
P(2 dogs or 2 cats).
= P(2 dogs) + P(2 cats)
= 1/4 + 1/4
= 1/2
Thus,
The probability of the family having two dogs or two cats is 1/2 or 50%.

Maria, Carolina and Pedro receives $1600 from their grandfather in ratio 7:5:4. calculate share of each.
Answers
Step-by-step explanation:
here's your solution
=> total money received by them = $1600
=> the given ratio are 7:5:4
=> let the ratio be X ,now
=> Maria = 7X
=> Carolina = 5X
=> Pedro = 4X
=> we know whole money = $1600
=> so, adding all
=>. 7x + 5x + 4x = $1600
=> 16x = $1600
=> x= $1600/16
=>. x = $100
now Maria = 7*100 = $700
Carolina = 5*100 = $500
Pedro = 4*100 = $400

Step-by-step explanation:
128211~}>■•
Step-by-step explanation:
1. The vertex is the x coordinate of the lowest point of the parabola. The lowest possible point is (1,-2). So our vertex is 1.
2. The axis of symmetry passes through the vertex so the axis of symmetry is at the line x=1 .
3. X intercepts are what are the x values when y =0. The x intercepts are -2 and 4.
4.Reflect the point 7,6 across the line x=1. A point symmetric to it is (-5,6)
On Friday, Carlotta had 6/8 of her paper left to write. She wrote 2/6 of the paper on Saturday and ¼ of the paper on Sunday. At the end of the weekend, what fraction of her paper does Carlotta have left to write?
Answers
Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
Skills needed: Fraction Subtraction, Least Common Denominator (LCD)
1) [tex]\frac{6}{8} - \frac{2}{6} - \frac{1}{4}[/tex] is the operation you would do.
--> You would do this because, Carlotta has [tex]\frac{6}{8}[/tex] of the paper left, and does one fraction amount ([tex]\frac{2}{6}[/tex]) on Saturday & does another fraction amount ([tex]\frac{1}{4}[/tex]) on Sunday.
--> Using subtraction is the best way
2) Now, we need to figure out the Least Common Denominator for all 3 fractions.
8,6,4 are the denominators.
The lowest number that is a factor of all them is 24.
So, it would then become [tex]\frac{18}{24} - \frac{8}{24} - \frac{6}{24}[/tex]
This would become: [tex]\frac{18-8-6}{24}[/tex] (18-8-6 = 4)
So then: [tex]\frac{4}{24}[/tex] is your answer.
This simplifies into [tex]\frac{1}{6}[/tex].

explain to a 7th grader how to find the x intercept and the y-intercept on a graph
Answers
The Slope-Intercept form of the equation of a line is: y=mx + b
where m=slope (often called "rise over run")
b = y-intercept (the point on the y-axis when x=0)
Given a slope and a y-intercept point [ (0,b) ],
(1) plot the point (0,b)
On the y-axis (x=0), find the point b.
(2) Now, do the "rise over run" exercise. For a slope of m, you go up m units on the y-axis for 1 unit of increase on the x-axis. For example, if m=4 the next point after (0,b) would be (1,b+4). Now, note that a negative m (a negative slope) means that the y-values decrease as the x-values increase.
Two points determine a line. "Connect the dots" and extend in both directions.

Logan is going to invest in an account paying an interest rate of 3.1% compounded continuously. How much would Logan need to invest, to the nearest ten dollars, for the value of the account to reach $990 in 6 years?
Answers
Answer:
yessir
Step-by-step explanation:
Answer: Rounded to the nearest $10 he would have to invest $830
Step-by-step explanation: While I am not completely familiar with this sort of math I am still relatively confident that I got the correct answer. Using the formula A = Pe^rt. First we can convert the percentage to a decimal so it can be used efficiently in the formula. So r = 3.1/100 which in turn equals 0.031 which is our decimal. Now we can simply input our information into the formula for our answer so follow along
A = 830 * e ^(0.031 * 6)
A = 830(2.718281828459045)^(0.186)
A = 999.67
And of course this is not exactly $990 because the question stated to round the original investment amount to the nearest 10 dollar. This should be your answer and if you have any other questions about this please do not hesitate to reach out :)

Answers
Given what we know, we can confirm that the perimeter of the image is 9 units.
Perimeter and Scale factor.To calculate the perimeter of a shape, we must add the length of all of its sides. When we dilate a shape, we multiply each of its sides by our scale factor.Our scale factor is [tex]\frac{3}{5}[/tex], which corresponds to 0.6 in decimal form Taking the sum of 15 as the perimeter of the preimage and multiplying by 0.6 gives us the perimeter of the image which is 9 units.Therefore, given that [tex]15units * \frac{3}{5} = 9 units[/tex], we can confirm that the perimeter of the image is 9 units.
