Justin's football team has a phone tree in case a game is cancelled,
The coach calls 2 players, Then each of those players calls 2 players, and
How many players will be notified during the 2nd round of calls?
EE
Answer: There will be 2 players notified in the 1st round of calls,
Those players will then call two players in the 2nd round of calls.
This second round will yield 2 x 2 = 4 players being contacted.
Therefore, 6 players will be contacted after the second round of calls.
Answer: 18 players will be notified during the 2nd round of calls.
Step-by-step explanation: When doing a simple question like this, just follow these steps: First, do 2x3 which equals 6. Then do 6x3, which equals 18. Then 54, then 162, then 486, and so on.
find the sum of the first 100 terms of the arithmetic sequence is 15250 while the sum of the next 100 terms is 45250. find the sum of the next 100 terms
The sum of the next 100 terms is 65250.
An arithmetic sequence is a sequence of numbers such that the difference between any two consecutive terms is constant. If we let "a" be the first term of the sequence and "d" be a common difference, then the nth term of the sequence is given by a + (n-1)d.
Since the sum of the first 100 terms is 15250 and the sum of the next 100 terms is 45250, we can write two equations to represent these sums:
100/2 * (2a + 99d) = 15250100/2 * (2a + 199d) = 45250We can use these equations to find the value of "d". Once we have found the value of "d", we can use the equation for the nth term to find the sum of the next 100 terms.
Subtracting the first equation from the second, we get:
100/2 * (100d) = 30000Dividing both sides by 100/2, we get:
d = 300Finally, using the equation for the nth term and n = 201, we get:
a + (200)d = a + 200*300 = 60000So, the sum of the next 100 terms is 65250.

you decide to go to the movies with your bestie. tickets to the movie is 13.00$ wednesday special, all snacks are 4.00$. a 32 oz drink cost 6.00$. you bought a ticket one beverage and a few snacks write and solve an equation. how many snacks did you purchase?
Let's assume that the total amount spent on the movie tickets and snacks is represented by x.
We know that:
The movie ticket costs $13.00
The drinks cost $6.00
Therefore, the equation representing the total amount spent is:
x = 13 + 6 + 4y
where y is the number of snacks purchased.
Let's substitute the given value of x:
23 = 13 + 6 + 4y
Subtracting 13 and 6 from both sides:
4 = 4y
Dividing both sides by 4:
y = 1
So, you purchased 1 snack.

2-5x=2x-2+3x is this equation a 1 solution a no solution or in infinite solution
The linear equation has only one solution, and it is x = 2/5.
How many solutions does the linear equation has?Here we want to see how many solutions does the linear equation have.
The equation is:
2 - 5x = 2x - 2 + 3x
To check that, let's try to solve the equation.
We can simplify the right side to get:
2 - 5x = (2x + 3x) - 2
2 - 5x = 5x - 2
Nowwe canadd 5x in both sides to get:
2 - 5x + 5x = 5x -2 + 5x
2 = 10x - 2
Now add 2 in both sides:
2 + 2= 10x - 2 + 2
4 = 10x
4/10 = x
2/5 = x
So that is the solution (and we know that there is only one because this is a linear equation).

No, blinding was not demonstrated in the experiment because the volunteers knew whether they are drinking purple juice or yellow juice.
What is blinding in an experiment?Blinding is the process of hiding a participant's group assignment from one or more other participants in a clinical research study, most frequently a randomized controlled trial (RCT).
Although the candy has the same flavour as the drink, participants can tell the difference based on colour. No, because the participants are aware of whether they are consuming yellow or purple juice.
To create a yellow or pink candy, two separate additives that don't affect flavour are added to identical sweets.
In each experiment, group allocations are concealed from data analyzers by blinding or masking. This experiment is not a blinding demonstration since the subject is aware of the juice.
As a result, adolescent volunteers are at random allocated either pink candy or yellow candy, both of whom are aware of the juice.

The volume of the solid is 16.75 unit³ in the given line x+2y=8 intercseting the x-axis, the y-axis.
What is volumes of Solids?
We shall encounter several solids and their corresponding volumes when discussing the concept of the volume of combination of solids. As is common knowledge, the surface areas and volumes of all three-dimensional shapes depend on their dimensions. As we can see in reality, numerous shapes are created by fusing a variety of shapes. For instance, the combination of a cone and cylinder shapes creates a tent. Similar to how a cone and a hemisphere combine to form an ice cream cone. As a result, the volume of the solids combined will equal the total of the volumes of the individual solids.
The line x+2y=8.
y = (8-x)/2
Volume will be V = π/2 ∫(r²) dr
So we have 1/3 π * r² * h
Here h = 8, r=2.
So V = 1/3 π * r² * h = 1/3 π * 2² * 8
V = 16.75 unit³
Hence ,the volume of the solid is 16.75 unit³

given a standardized normal distribution, between what two values of z (symmetrically distributed around the mean) will 68.26 percent of all possible z values be contained?
68.26% of all possible z values are contained between -1 and 1.
The formula for the 68-95-99.7 rule states that 68% of the data should fall within 1 standard deviation of the mean, 95% of the data should fall within 2 standard deviations of the mean, and 99.7% of the data should fall within 3 standard deviations of the mean. Therefore, for a standardized normal distribution, 68.26% of all possible z values are contained between -1 and 1.
To calculate this, first recall that for a normal distribution, the mean is 0 and the standard deviation is 1. Then use the 68-95-99.7 rule to determine that 68% of the data should be contained within 1 standard of the mean. Since the mean is 0, this means that 68% of the data should be contained between -1 and 1. Therefore, 68.26% of all possible z values are contained between -1 and 1.

How to estimate the number of years?First, we want to estimate the number of years that takes to reach 40 thousand, to estimate that we need to look at the graph.
We can see that when y = 40, the value of x is between 20 and 25 (almost in the middle)
So here we estimate that the answer is 22.5
b) Now we want to estimate it using the equation
p(x) = 18*e^(0.035*x)
We want to find how many years it takes to reach a population of 60 thousand, then we need to solve:
p(x) = 18*e^(0.035*x) = 60
e^(0.035*x) = 60/18
Using the natural logarithm in both sides:
ln( e^(0.035*x)) = ln(60/18)
0.035*x = ln(60/18)
x = ln(60/18)/0.035 = 34.4
