Answer:
In the equation y = 210(1.082)^e, the y-intercept is the value of y when e = 0. When e = 0, the exponent (1.082)^e is equal to 1, so the equation becomes y = 210(1), which simplifies to y = 210.
Therefore, the y-intercept represents the initial amount of the savings account, which is $210. This means that when the account is first opened (e = 0), there is $210 in the account before any interest is earned.

The mean class size at Mountain View School is 4.4 and at Seaside School is 4.2.
The median class size is 5 for both schools.
The range for Mountain View School is 12 and for Seaside School is 8.
The IQR for Mountain View School is 6 and for Seaside School is 3.
How do we solve this?To find the measures of center, we can calculate the mean and median for both schools.
Mountain View School:
Mean = (2+1+0+5+8+6+9+8+2+0+1+0+6)/15
Mean = 4.4
Median = 5
Seaside School:
Mean = (0+1+2+5+6+8+8+7+6+5+5+4+4+3+1+0)/15
Mean = 4.2
Median = 5
Part B:
To find the measures of variability, we can calculate the range and interquartile range (IQR) for both schools.
Mountain View School:
Range = largest value - smallest value = 12 - 0
Range = 12
IQR = Q3 - Q1 = 8 - 2 = 6
Seaside School:
Range = largest value - smallest value = 8 - 0
Range = 8
IQR = Q3 - Q1 = 7 - 4 = 3
Part C:
If we are interested in a smaller class size, Seaside School would be the better choice. The median class size is the same at both schools, but Seaside School has a smaller mean, which suggests that on average, class sizes are smaller.
Additionally, the range and IQR are both smaller for Seaside School, indicating less variability in class size.

If a regular polygon had 360 side, what would each exterior angle measure? What would each interior angle measure?
Therefore, each internal angle would be 178 degrees in a regular polygon with 360 sides.
what is angle ?In mathematics, an angle is a figure made up of two rays that share a shared endpoint and are referred to as the sides of the angle and the vertex of the angle, respectively. Angles are typically measured in degrees, radians, or other angle measurement units. Angles can be categorized based on how wide they are. An acute angle is one that is less than 90 degrees, an obtuse angle is one that is higher than 90 degrees but less than 180 degrees, and a right angle is one that is 90 degrees. A reflex angle is greater than 180 degrees but less than 360 degrees, and a straight angle is precisely 180 degrees.
given
Since a polygon with that many sides would have sides that are extremely tiny in relation to the radius, if a regular polygon has 360 sides, it is a circle. Since every group of points in a regular polygon has an equal exterior angle and the sum of all exterior angles in a circle is 360 degrees, each exterior angle in a regular polygon would be measured as follows:
360 edges / 360 degrees = one degree.
Each interior angle of a regular polygon with n sides can be determined using the following formula:
Inner angle is equal to (n-2) x 180 / n.
When we enter n = 360 into this algorithm, we obtain:
(360-2) x 180 degrees / 360 = 178 degrees is the interior angle.
Therefore, each internal angle would be 178 degrees in a regular polygon with 360 sides.

g in a study, the sample is chosen by separating all cars by size, and selecting 10 of each size grouping what is the sampling method?
The sampling method used in the study where the sample is chosen by separating all cars by size, and selecting 10 of each size grouping is known as stratified random sampling.
Stratified random sampling is a method of sampling that involves dividing the population into smaller sub-groups known as strata. In this method, each stratum is composed of elements that have similar characteristics.
The strata could be based on demographic characteristics such as age, sex, education, and so on. Once the strata have been created, the next step is to select a sample from each of the strata to make up the final sample. The selection is done randomly, and the number of elements selected from each stratum is proportional to the size of the stratum. This ensures that the sample is representative of the entire population in terms of the different characteristics of the population.

What is the end behavior of function h? h(x)=-4x^2+11
We can conclude that the end behavior of the function [tex]$h(x)$[/tex] is that it approaches negative infinity as [tex]$x$[/tex] approaches either positive or negative infinity.
What is meant by end behavior?
End behavior refers to the behavior of a function as the input (usually denoted by x) becomes extremely large (approaches positive or negative infinity). It describes the trend of the function as the input approaches infinity or negative infinity, and is determined by the highest-degree term of the function.
To determine the end behavior of the function [tex]$h(x)=-4x^2+11$[/tex], we can use limits. Specifically, we can evaluate the limit of [tex]$h(x)$[/tex] as [tex]$x$[/tex] approaches positive infinity and as [tex]$x$[/tex] approaches negative infinity.
As [tex]$x$[/tex] approaches positive infinity, we have:
[tex]\lim_{x \to \infty} h(x)= \lim_{x \to \infty} (-4x^2+11) = - \infty[/tex]
This tells us that as [tex]$x$[/tex] gets larger and larger, the value of [tex]$h(x)$[/tex] becomes more and more negative, eventually approaching negative infinity.
Similarly, as [tex]$x$[/tex] approaches negative infinity, we have:
[tex]\lim_{x \to -\infty} h(x)= \lim_{x \to -\infty} (-4x^2+11) = - \infty[/tex]
This tells us that as [tex]$x$[/tex] gets more and more negative, the value of [tex]$h(x)$[/tex] becomes more and more negative, also approaching negative infinity.
Therefore, we can conclude that the end behavior of the function [tex]$h(x)$[/tex] is that it approaches negative infinity as [tex]$x$[/tex] approaches either positive or negative infinity.

If the number of tolls collected varies directly as the number of vehicles and $129 was collected from 20 vehicles, how many vehicles result in the collection of $3225? Show how you arrived at your answer
Answer:
500 vehicles
Step-by-step explanation:
let t represent number of tolls and v represent number of vehicles.
given that t varies directly with v then the equation relating them is
t = kv ← k is the constant of variation
to find k use the condition t = 129 from v = 20 , then
129 = 20k ( divide both sides by 20 )
6.45 = k
t = 6.45v ← equation of variation
when t = 3225 , then
3225 = 6.45v ( divide both sides by 6.45 )
500 = v
the number of vehicles is 500
4 cleaner can clean all the rooms in a hotel in 7 1/2 hours. How long will it take 6 cleaners working at the same rate to clean all the rooms in the hotel?
it will take 6 cleaners working at the same rate to clean all the rooms in the hotel in 5 hours.
If 4 cleaners can clean all the rooms in a hotel in 7 1/2 hours, we can start by using the concept of work rate. Work rate is a measure of how much work is completed in a certain amount of time. If we assume that the work rate of each cleaner is constant, we can set up a proportion to find how long it will take 6 cleaners to clean the same amount of rooms:
4 cleaners can clean all the rooms in 7 1/2 hours.
Therefore, 1 cleaner can clean all the rooms in (4 x 7 1/2) hours = 30 hours.
So, if 1 cleaner takes 30 hours to clean all the rooms, then 6 cleaners working at the same rate will take:
(time for 1 cleaner) / (number of cleaners) = (30 hours) / (6 cleaners) = 5 hours
Therefore, it will take 6 cleaners working at the same rate to clean all the rooms in the hotel in 5 hours.
It is important to note that this assumes that the work rate of each cleaner is constant and that there are no factors that may affect the cleaning time, such as interruptions or changes in the number of rooms to be cleaned. Additionally, the optimal number of cleaners may vary depending on the size of the hotel and the specific cleaning needs.

1. The initial deposit is $10,000 since John deposited this amount to open the savings account.
2. The common ratio can be calculated using the formula for compound interest: A = P(1 + r/n)^(nt)
3. After 8 years, the amount will be $13,685.70 in the savings account.
How do we get how much money in account after 8 years?The formula which will be used to calculated the compound interest is A = P(1 + r/n)^(nt). For this problem, the interest is compounded annually, so n = 1.
The annual interest rate is 4%, or 0.04 as a decimal. Plugging these values into the formula, we get:
A = $10,000*(1 + 0.04/1)^(1*8)
A = $10,000*(1.04)^8
A = $10,000*1.36857
A = $13,685.70
Therefore, after 8 years, there will be $13,685.70 in the savings account.

the radius of a circle is changing at .5 cm/sec. find the rate of change of the area when the radius is 4 cm.
The rate of change of the area of a circle when the radius is 4 cm is 4π cm2/sec.
This can be calculated using the formula for the area of a circle (A = πr2) and the chain rule for derivatives. The chain rule states that when the radius (r) changes, the area of a circle (A) is equal to 2πr times the rate of change of the radius (dr/dt).
Therefore, the rate of change of the area of a circle when the radius is 4 cm is equal to 2π(4 cm) × (0.5 cm/sec) = 4π cm2/sec.
Note that if the rate of change of the radius were different, the rate of change of the area would also be different. This formula can be used to calculate the rate of change of the area of a circle at any given radius, as long as the rate of change of the radius is known.

Starting with the function f(t) = -100[tex](1.05)^t[/tex], to translate it 5 units to the right and 50 units up, we can replace t with (t - 5) to shift it to the right, and add 50 to the whole function to shift it up. This gives us:
g(t) = f(t - 5) + 50
g(t) = -100[tex](1.05)^(t - 5)[/tex]+ 50
Simplifying this equation, we can use the properties of exponents to rewrite [tex](1.05)^(t - 5)[/tex] as [tex](1.05)^t[/tex] * [tex](1.05)^(-5)[/tex]:
g(t) = -100[tex](1.05)^t[/tex] *[tex](1.05)^(-5)[/tex]+ 50

The random variable x in this case is a binomial random variable, representing the number of cars that need to be inspected until a car fails an inspection. A binomial random variable is defined as the number of successes, “s”, in “n” independent trials. In this case, “s” would be 1 (the single failure) and “n” would be the number of cars that John inspects until a car fails inspection.
The probability of success, “p”, in this case is 0.06 since 6% of cars fail inspection. The probability of failure is “q”, which would be 0.94 in this case (1 - 0.06). The mean, “μ”, of the random variable x is equal to n * p, or the total number of trials times the probability of success. In this case, the mean would be equal to n * 0.06, or 6%.
The variance, “σ2”, of the random variable x is equal to n * p * q, or the total number of trials times the probability of success times the probability of failure. In this case, the variance would be equal to n * 0.06 * 0.94, or 5.64%.
The binomial random variable x can be used to calculate the expected number of inspections it will take John until a car fails an inspection, as well as the probability of a car failing an inspection. By knowing the probability of success, the number of trials, and the probability of failure, we can calculate the mean, variance, and expected value of the binomial random variable x.

a study indicates that the weights of adults are normally distributed with a mean of 140 lbs and a standard deviation of 25 lbs. what is the probability that a randomly selected adult weights between 120 and 165 lbs?
The probability that a randomly selected adult weighs between 120 and 165 lbs is approximately 0.8186.
Since the weights of adults are normally distributed with a mean of 140 lbs and a standard deviation of 25 lbs, we can use the standard normal distribution to calculate the probability.
We first need to standardize the values using the formula: z = (x - μ) / σ, where x is the weight, μ is the mean, and σ is the standard deviation.
For x = 120 lbs, z = (120 - 140) / 25 = -0.8, and for x = 165 lbs, z = (165 - 140) / 25 = 1.0. We can then use a calculator to find the probability between -0.8 and 1.0, which is approximately 0.8186.
Thus, the chance of picking an adult at random who weighs between 120 and 165 lbs is roughly 0.8186.

by how much must the sample size n be increased if the width of the ci (7.5) is to be halved? if the sample size is increased by a factor of 25, what effect will this have on the width of the interval? justify your assertions.
The width of the interval will be reduced to 1.5 if the sample size is increased by a factor of 25.
To find how much the sample size n must be increased if the width of the confidence interval is to be halved, use the following formula:
W = (zα/2 x σ/√n)W/2 = (zα/2 x σ/√n')
Where W is the initial width of the confidence interval,
zα/2 is the critical value of the standard normal distribution that corresponds to the level of significance α and the appropriate two-tailed area,
σ is the population standard deviation,
n is the initial sample size, and
n' is the new sample size needed to halve the width of the interval.
Rearranging the second equation to solve for n', we get:
n' = n(4)
So the sample size needs to be increased by a factor of 4, or 300% if the width of the confidence interval is to be halved.
If the sample size is increased by a factor of 25, the effect it will have on the width of the interval can be found using the following formula:
W' = (zα/2*σ/√25n) = (zα/2*σ/5√n)
The width of the interval will be divided by 5, or reduced to one-fifth of its initial value.

x −4 −1 0 1 2
y −4 2 −4 0 2
x 1 1 1 1 1
y −3 −2 −1 0 1
x −6 −1 0 2 3
y −7 negative sixteen thirds −5 negative thirteen thirds −4
x −2 −1 0 2 4
y −4 negative two thirds −1 two thirds 1
The table that represents a linear function is table 2.
How to explain the linear functionA linear function is a function whose graph is a straight line, and the equation of such function has the form y = mx + b, where m is the slope of the line and b is the y-intercept. To determine which table represents a linear function, we can calculate the slope between any two points in the table, and see if the slope is the same for all pairs of points.
Table 1:
The slope between (0,-4) and (1,0) is (0 - (-4)) / (1 - 0) = 4/1 = 4.
The slope between (-1,2) and (0,-4) is (-4 - 2) / (0 - (-1)) = -6/1 = -6.
The slope between (1,0) and (2,2) is (2 - 0) / (2 - 1) = 2/1 = 2.
The slopes are not the same for all pairs of points, so this table does not represent a linear function.
Table 3:
The slope between (-1, negative sixteen thirds) and (0,-5) is (-5 - (-16/3)) / (0 - (-1)) = -1/3.
The slope between (0,-5) and (2,-13/3) is (-13/3 - (-5)) / (2 - 0) = -8/3.
The slopes are not the same for all pairs of points, so this table does not represent a linear function.
Table 4:
The slope between (-1,negative two thirds) and (0,-1) is (-1 - (-2/3)) / (0 - (-1)) = -1/3.
The slope between (0,-1) and (2,2/3) is (2/3 - (-1)) / (2 - 0) = 5/6.
The slopes are not the same for all pairs of points, so this table does not represent a linear function.
Therefore, the correct option is table 2.

GIVING BRAINLIEST FOR THE CORRECT ANSWER (i need a proof that what you’re saying is right bc ppl are giving me the wrong answers)
Answer:
x [tex]\geq[/tex]2
Step-by-step explanation:
Since the arrow is pointing to the right, we know that it is greater than two. We also know that it could be equal to 2 because the dot is filled in on the number line. So, the answer is x is greater than or equal to 2.
true or false (and state why): if a sample from a population is large, a histogram of the values in the sample will be approximately normal, even if the population is not normal.
By the central limit theorem, with a large random sample, the sample histogram will not closely resemble the normal curve but with a large random sample, the probability density function of the sample mean closely resembles the normal curve.
The central limit theorem for samples says that if we keep drawing larger and larger samples and calculating their means, the sample forms their own normal distribution (the sampling distribution). The normal distribution will have the same mean as the original distribution and a variance that equals the original variance divided by the sample size. The variable n is the number of values that are averaged together,and not the number of times the experiment is done.
Hence,with a large random sample, the sample histogram will not resemble the normal curve but with a large random sample, the probability density function of the sample mean will closely resemble the normal curve.
The complete question is-
true or false: (justify/explain your answer) state whether a or b is the true statement below and then explain why the other statement is false. a. with a large random sample, the sample histogram will closely resemble the normal curve. b. with a large random sample, the probability density function of the sample mean will close resemble the normal curve.
