if a box of pen given 200 children each will get to Pen if the number of children is reduced by 10 how many pens would each get
Answers
Answer:
20
Step-by-step explanation:
So origianally, a box of 200 pens gave 2 each to every child. IThat means that there were 100 kids origianally. How? 200/2=100.
If they reduced it by 10, then 100/10=10.
200 / 10 = 20.
So each child would get 20 pens!

what are the major differences between a population that is experiencing logistic growth and one that is experiencing exponential growth?
Answers
If resources are unlimited, population will increase exponentially. A logistic growth happens as those resources are less readily available.
Explain the term logistic growth and exponential growth?Exponential Growth:
The term "exponential growth" describes a population's expansion through time at a pace that is directly proportionate to its size. The population's size is influenced by both the birth and death rates. When there are plenty of resources for everyone in the population, exponential expansion happens. When the number of objects is plotted against time, it yields a J-shaped curve.Logistic Growth:
A population growth known as logistic growth is a group of people whose rate of growth reduces as the number of individuals increases and becomes zero whenever the population reaches its maximum.People in the population compete for resources so when food supply and available space are limited.Thus, there are several key distinctions between populations growing logistically and those growing exponentially.
If resources are unlimited, population will increase exponentially. A logistic growth happens as those commodities become less widely available.To know more about the exponential growth, here

Two dice are rolled. Let X and Y denote, respectively, the largest and the smallest values obtained a. Compute the conditional probability mass function of Y-i given X-1, for i-1,2, ..., 6 b. Are X and Y independent? Why or why not?
Answers
The conditional PMF of Y=i given X=1 is 1 if i=1 and 0 otherwise and X and Y are not independent because the value of X affects the possible range of values for Y.
a. To compute the conditional probability mass function (PMF) of Y=i given X=1, we need to find the probability of Y=i when X=1. Since X=1, the only possible outcome is (1,1), and Y can only be 1. Hence, the conditional PMF of Y=i given X=1 is:
P(Y=i | X=1) = 1, if i=1; 0, otherwise.
b. X and Y are not independent. If they were independent, the outcome of one die roll would not provide any information about the other die roll. However, given that X is the largest value and Y is the smallest value, we can see that X directly affects the possible range of values for Y. If X is 6, then Y cannot be greater than 6. Therefore, the values of X and Y are dependent on each other, and they are not independent.
Therefore, The conditional PMF of Y=i given X=1 is 1 if i=1 and 0 otherwise and X and Y are not independent because the value of X affects the possible range of values for Y.

There are 7 degrees of freedom for the pooled-variance t-test.
To perform a pooled-variance t-test, we need to calculate the degrees of freedom. The formula for degrees of freedom in a pooled-variance t-test is:
\(\[\text{{df}} = n_1 + n_2 - 2\]\)
where \(\(n_1\)\) and \(\(n_2\)\) are the sample sizes of the two independent samples.
In this case, \(\(n_1 = 4\)\) and \(\(n_2 = 5\)\). Substituting these values into the formula, we get:
\(\[\text{{df}} = 4 + 5 - 2 = 7\]\)
In a pooled-variance t-test, we combine the sample variances from two independent samples to estimate the population variance. The degrees of freedom for this test are calculated using the formula \(df = n1 + n2 - 2\), where \(n_1\)and \(n_2\) are the sample sizes of the two independent samples.
To understand why the formula is \(df = n1 + n2 - 2\), we need to consider the concept of degrees of freedom. Degrees of freedom represent the number of independent pieces of information available to estimate a parameter. In the case of a pooled-variance t-test, we subtract 2 from the total sample sizes because we use two sample means to estimate the population means, thereby reducing the degrees of freedom by 2.
In this specific case, the sample sizes are \(n1 = 4\) and \(n2 = 5\). Plugging these values into the formula gives us \(df = 4 + 5 - 2 = 7\). Hence, there are 7 degrees of freedom for the pooled-variance t-test.
Therefore, there are 7 degrees of freedom for the pooled-variance t-test.

Answers
The area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.
How to calculate for the area of the polygonArea of regular polygon = 1/2 × apothem × perimeter
perimeter = (s)side length of octagon × (n)number of side.
apothem = s/[2tan(180/n)].
11 = s/[2tan(180/12)]
s = 11 × 2tan15
s = 5.8949
perimeter = 5.8949 × 12 = 70.7388
Area of dodecagon = 1/2 × 11 × 70.7388

The volume of the object is 285 cubic feet based on the individual volume of cylinder and rectangular prism.
We will calculate the volume of each shape individually followed by their addition.
To calculate the volume of cylinder, we will find radius.
Radius = diameter/2
Radius = 4/2
Radius = 2 ft
Volume of cylinder = πr²h, where r is radius and h is height. Keep the values in formula -
Volume of cylinder = 3 × 2² × 5
Take square and multiply the digits
Volume of cylinder = 60 cubic feet
Volume of rectangular prism = l × w × h, where l is length, w is width and h is height
Volume of rectangular prism = 5 × 5 × 9
Volume = 225 cubic feet
Total volume = 60 + 225
Total volume = 285 cubic feet
Hence, the volume of object is 285 feet.

a trade magazine routinely checks the drive through service times of fast food restaurants. a 90% confidence interval that results from examining 653 customers in one fast food chains drive through has a lower bound of 178.2 secinds and an upper bound of 181.6 seconds. what does this mean?
Answers
The 90% confidence interval obtained from examining 653 customers in one fast food chain's drive-through has a lower bound of 178.2 seconds and an upper bound of 181.6 seconds. This means that based on the sample data collected from the 653 customers, we can be 90% confident that the true average drive-through service time for this fast food chain falls within the range of 178.2 seconds to 181.6 seconds.
In other words, if we were to repeatedly sample 653 customers from the same fast food chain's drive-through and calculate confidence intervals, approximately 90% of those intervals would contain the true average service time of the entire population of customers.
The range between the lower and upper bounds of the confidence interval provides an estimate of the precision or uncertainty associated with our sample mean.
The narrower the interval, the more precise our estimate of the true population mean becomes. In this case, the interval is relatively narrow, indicating a relatively precise estimate of the average drive-through service time for this fast food chain based on the sample data.

chris has been given a list of bands and asked to place a vote. his vote must have the names of his favorite and second favorite bands from the list. how many different votes are possible?
Answers
There are nC2 different votes possible, where n is the number of bands on the list and nC2 represents the number of ways to choose 2 bands out of n.
To calculate nC2, we can use the formula for combinations, which is given by n! / (2! * (n-2)!), where ! represents factorial.
Let's say there are m bands on the list. The number of ways to choose 2 bands out of m can be calculated as m! / (2! * (m-2)!). Simplifying this expression further, we get m * (m-1) / 2.
Therefore, the number of different votes possible is m * (m-1) / 2.
In the given scenario, we don't have the specific number of bands on the list, so we cannot provide an exact number of different votes. However, you can calculate it by substituting the appropriate value of m into the formula m * (m-1) / 2.
