Step-by-step explanation:
The probability of rolling a 6 on a 6-sided die is 1/6, and the probability of rolling a 4 on a 6-sided die is also 1/6.
Assuming that the rolls are independent (i.e., the outcome of one roll does not affect the outcome of the other roll), the probability of rolling a 6 and then a 4 is the product of the probabilities of each individual event:
Probability of rolling a 6 and then a 4 = (Probability of rolling a 6) x (Probability of rolling a 4)
= (1/6) x (1/6)
= 1/36
Therefore, the probability of rolling a 6 and then a 4 on a 6-sided die rolled twice is 1/36, or approximately 0.0278 (2.78%).

Answers
Answer:
I don't think anyone is going to answer ALL of those questions but ill get you started...
Step-by-step explanation:
1: 7.8 billion. Used billions as my unit. Did not use a site, I already knew this information.
2: The population has increased by approximately 12% in the last 10 years. Worldometer.com shows this information.
3: 1950 population: 2.5 billion, 1960 population: 3.039 billion. The population comparison can be achieved by looking at the increase in billions. The increase was almost 0.6 billion.
Hopefully, that can get you started.
The measures of two angles in a triangle are 32o and 78o. Which of the following equations could be used to find the measure of the third angle, x?
(the ¨o¨ is a degree symbol)
180−32+78=x
180−32=x−78
180−(32+782÷2)=x
32+78+x=180
Answers
Answer:
32+78+x=180
Step-by-step explanation:
All triangle angles add up to 180, so add 78 and 32 then subtract it from 180 to get x, which in another form is 32+78+x=180.
Answer:
32 + 78 + x = 180
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180, that is
32 + 78 + x = 180

Marcus needs 12 cups of edible flowers to make the breakfast mixture to feed the zoo's emperor tamarin monkey troop for the week. The number of cups of edible flowers the zoo has in storage is represented by the expression 1.875c−(c+0.5d). If c=25 and d=20, does Marcus have enough edible flowers to make the breakfast mixture for the emperor tamarin monkeys?
No, because 1.875(25)-((25)+0.5(20))=11.875, which is less than 12.
No, because 1.875(25)−((25)+0.5(25))=9.375, which is less than 12.
No, because 1.875(20)−((25)+0.5(20))=2.5, which is less than 12.

Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

2. Pencils measuring less than 5 inches: 3 + 2 + 3 = 8 inches in total.
3. False. To determine if more than half of the pencils are 6 inches or shorter, we need to find the total number of pencils and calculate how many of them are 6 inches or shorter.
Total number of pencils = 4 + 3 + 2 + 3 + 7 + 8 = 27
Number of pencils that are 6 inches or shorter = 4 + 3 + 2 + 3 = 12
To find out if more than half of the pencils are 6 inches or shorter, we need to divide the number of pencils that are 6 inches or shorter by the total number of pencils and multiply by 100%:
12/27 x 100% = 44.44%
Since 44.44% is less than 50%, the statement is false.
4. There are three pencils that measure more than 5.5 inches but less than 7.5 inches: 6, 6, and 7. Therefore, the answer is 3 pencils.

PLZ HELP!!!
Answers
Answer:
33
Step-by-step explanation:
We can write an equation:
x+x+1+x+2+x+3=130
x represents the smallest number of the consecutive integers
By the way, an example of consecutive would be 2, 3, 4, 5 or 10, 11, 12, 13
We can combine like terms from our equation:
4x+6=130
4x=124
x=31
The smallest number is 31. The second number would be 31+1=32, which means the third number is 33!
Hope this helps! :) :)
Answer:
\(\huge\boxed{3rd\ number = 33}\)
Step-by-step explanation:
Let the consecutive numbers(Coming one after another) be x, x+1, a+2 and x+3
So,
x+x+1+x+2+x+3 = 130
4x + 6 = 130
Subtracting 6 to both sides
4x = 130-6
4x = 124
Dividing both sides by 4
x = 32
So,
1st number = x = 31
2nd Number = x+1 = 31+1 = 32
3rd number = x+2 = 31+2 = 33
4th number = x+3 = 31+3 = 34

Describe a simulation that you can use to model this situation. The simulation should be different from the one in part C.
Space used (includes formatting): 0 / 15000
Answers
Answer: all awnsers below
Step-by-step explanation:
1. Define the number of coin flips to be simulated (e.g., 1,000 flips).
2. Initialize two counters, `headsCount` and `tailsCount`, to keep track of the number of heads and tails, respectively.
3. Repeat the following steps for the specified number of coin flips:
a. Generate a random number between 0 and 1.
b. If the generated number is less than 0.5, increment `headsCount` by 1. Otherwise, increment `tailsCount` by 1.
4. Calculate the experimental probabilities by dividing `headsCount` and `tailsCount` by the total number of coin flips.
5. Compare the experimental probabilities with the theoretical probability (0.5 for a fair coin).
6. Repeat the simulation multiple times (e.g., 100 times) and calculate the average difference between the experimental and theoretical probabilities to evaluate the simulation's accuracy.
By running this simulation multiple times, we can assess how closely the experimental probabilities match the theoretical probability on average. This simulation provides a different approach compared to the previous one and can be used to model the situation with more flexibility and accuracy.

The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

Answers
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.
