Determine whether each function is an example of exponential growth or decay. Then, find the y -intercept. y=0.0015(10) x
Answers
The function y=0.0015(10)ˣ showcases exponential growth.
What do we mean by exponential function?An exponential function is a mathematical function with the formula f (x) = ax.Where an is the function's base constant and x is a variable.The most common exponential-function base is the transcendental number e, or approximately 2.71828.So,
Given function: y=0.0015(10)ˣ
If we put x = 1 as follows:
y = 0.0015×10y = 0.015Then, if we put x = 2 as follows:
>>y = 0.0015×(10)²>>y = 0.0015×100>>y = 0.15Hence, we see that 0.15 > 0.15.
So, when x increases, y also increases.Therefore, the function y=0.0015(10)ˣ showcases exponential growth.

select the best definition of random variation. multiple choice question. unusual variation that occasionally occurs in a process. variation that can happen any day, any time. common variation inherent in a process occurring by chance.
Answers
The best definition of random variation is: "Common variation inherent in a process occurring by chance."
In mathematics, random variation refers to the inherent variability that arises in the outcome of a random experiment. It is a type of natural variability that cannot be predicted with certainty and is due to chance. For example, if we toss a fair coin multiple times, we can expect to see some variation in the number of heads and tails that appear, even though the coin is fair and each toss is independent of the previous ones. This variation is random and follows a probability distribution that can be modeled mathematically. Understanding random variation is important in statistical inference and modeling, as it allows us to estimate the uncertainty in our results and make informed decisions based on probabilistic reasoning.

Thee factory is able to provide 94.38 boxes per hour to the warehouse.
How to calculate the valueRate = (2000 - 1245) / 8 = 94.38 boxes per hour
Therefore, the factory is able to provide 94.38 boxes per hour to the warehouse.
Boxes added in 40 hours = rate * time = 94.38 * 40 = 3,775.2
Therefore, the inventory at the end of a 40-hour work week would be:
1245 + 3775.2 = 5020.2 boxes
rate = (50000 - 1245) / time
Simplifying this equation, we get:
time = (50000 - 1245) / rate = 511.64 hours (rounded to two decimal places).
Therefore, it will take approximately 511.64 hours to fill the warehouse to its 50,000 box capacity,

Logan was paid $45 for 3 hours of work on Friday. He was paid $90 for 6 hours of work on Saturday.
Are Logan’s pay rates, in dollars per hour, proportional for these 2 days? please help
Answers
Answer:
Yes, Logan's pay rates are proportional for those 2 days.
Step-by-step explanation:
First, we have to figure out what 6 divided by 3 is.
6 ÷ 3 = 2
So, now we have to divide 90 by 45.
90 ÷ 45 = 2.
So, yes it is proportional because 6 ÷ 3 = 2 and 90 ÷ 45 is also 2 so yes it is proportional.

A piece of cheese is shaped like a triangle. It has a height of 3.5 inches and a base that is 4.25 inches long. If 1 inch = 2.54 centimeters, find the area of the cheese in square centimeters. Round the answer to the nearest square centimeter.
20 cm2
10 cm2
96 cm2
48 cm2
Answers
Answer:
The answer would be 48 cm2
Step-by-step explanation:
1. We need to convert the inches to square centimeters.
We multiply 3.5 × 2.54, which is 8.89. We can round this to 8.90.
We also multiply 4.25 × 2.54, which is 10.79500. We can round this to 10.80.
2. The formula to find the area of a triangle is \(a= \frac{hb}{2}\)
3. We plug the numbers into the formula. \(a= \frac{(8.90) (10.80) }{2}\)
4. 8.90 × 10.80 = 96.12
5. 96.12 ÷ 2 = 48.06
6. Round 48.06 to the nearest square centimeter to get 48 cm2
An SRS of 25 recent birth records at the local hospital was selected. In the sample, the average birth weight was x=119.6 ounces. Suppose the standard deviation is known to be σ=6.5 ounces. Assume that in the population of all babies born in this hospital, the birth weights follow a Normal distribution, with mean μ. If the sample size of birth records increases, how does the sampling distribution change? The sampling distribution will remain Normal, regardless of the sample size, and will have the same average and standard deviation as the sampling distribution computed from the smaller sample. The shape of the distribution will change, but it is not possible to determine what the new distribution will be without knowing the new data. The sampling distribution will remain Normal and the mean will remain the same, regardless of the sample size, but its standard deviation will be smaller than the sampling distribution based on the smaller sample. The shape of the distribution will change, but it is dependent upon the new data that is collected.
Answers
Option C is correct: The sampling distribution will remain Normal and the mean will remain the same, regardless of the sample size, but its standard deviation will be smaller than the sampling distribution based on the smaller sample.
The central limit theorem states that as the sample size increases, the sampling distribution of the sample means becomes more normally distributed, with a smaller standard error. The shape of the distribution is still Normal, but the standard deviation becomes smaller. The standard deviation is inversely proportional to the square root of the sample size. As a result, as the sample size grows, the standard deviation of the sampling distribution decreases.
The larger the sample size, the smaller the standard deviation of the sample mean is, assuming the population standard deviation is constant. The mean of the sample remains unchanged. Therefore, c) the sampling distribution will remain normal, and the mean will stay the same regardless of the sample size.

1. How can you use addition to check
that 1.55 cm is the difference in the
wingspans of the two butterflies?
Answers
The check using addition, the value of difference is added to the smaller value which should give the larger wingspan value.
The value of the wingspan of the butterflies aren't given, however, we could take hypothetical values for the wingspan of the two butterflies :
Wingspan of Butterfly A = 5.55 cm
Wingspan of Butterfly B = 4 cm
This means that, the difference in the wingspan is :
Wingspan of A - Wingspan of B
5.55 cm - 4 cm = 1.55cm
To check using addition :
The value of the difference added to the value of the butterfly with the lower wingspan should give the value of the wingspan of butterfly B(larger wingspan).
This means:
4cm + 1.55cm = 5.55 cm
Hence, the value of the difference is correct.
