A city's population is represented by the function P=25,000(1.0095)t , where t is time in years.
How could the function be rewritten to identify the daily growth rate of the population?
What is the approximate daily growth rate?
Answers
The daily population growth function is P=25,000((1.0095)1/365.25)t, and the daily growth rate is approximately 1.000026 or an increase of about 0.0026% per day.
Explanation:The city population growth function given, P=25,000(1.0095)t, is an exponential function. To identify the daily growth rate, we need to rewrite this function in terms of days. As there are approximately 365.25 days in a year, we substitute this into the formula for t. Hence, the daily population growth function becomes P=25,000(1.0095)t/365.25.
To find the approximate daily growth rate, we solve for the base of the exponent. Using the fact that (ab)c = abc, we can rewrite the function as P=25,000((1.0095)1/365.25)t.
Thus, the daily growth rate of the population is approximately the value of (1.0095)1/365.25, which calculates to about 1.000026, or an increase of about 0.0026% per day.

The base of the building is an equilateral triangle 180 meters on each side. The height of the prism is 25m. Find the height, of the triangular base.
Answers
The height of the triangular base is 155.46 m.
To find the height of the equilateral triangle base of the prism, we'll first determine the height of one of its constituent triangles.
The height ( h ) of an equilateral triangle is given by [tex]\( h = \sqrt{3}/2 \times \text{side length} \).[/tex]
Calculate the height of one triangle:
[tex]\[ h = \frac{\sqrt{3}}{2} \times 180 \, \text{m} = \frac{\sqrt{3} \times 180}{2} = \frac{180\sqrt{3}}{2} = 90\sqrt{3} \, \text{m} \][/tex]
Calculate the total height of the prism:
The height of the prism is given as 25 m.
Calculate the total height:
Total height = height of one triangle + height of the prism
[tex]\[ \text{Total height} = 90\sqrt{3} \, \text{m} + 25 \, \text{m} = 90\sqrt{3} + 25 \, \text{m} = 155.46 \, \text{m} \][/tex]
So, the height of the triangular base is 155.46 m

Answers
what percent of the pies were apple...
3/16 = 0.1875 = 18.75% <=
Answer:
18.75%
Step-by-step explanation:
Mr. Potts, the college Pastry Chef baked pies for the student fundraiser.
He baked apple pies = 3
Blueberry pies = 2
Cherry pies = 5
Key lime pies = 6
We have to calculate the percentage of the apple pies.
Total number of pies that he baked = 3 + 2 + 5 + 6 = 16 pies
Percentage of Apple pies = [tex]\frac{3}{16}[/tex] × 100
= 0.1875 × 100
= 18.75%
18.75% was apple pie.

If the population decreases with a constant rate of change and the decrease is 7% in the first year, what will the town's population be in 6 years? (round to the nearest person)
Answers
If the population decreases with a constant rate of change and the decrease is 7% in the first year.
The decrease in the population of the town in the first year is given by 0.07 x 33,000 = 2,310
The decrease in the population of the town in 6 years is given by 2,310 x 6 = 13,860
Therefore, in 6 years, the town's population will be 33,000 - 13,860 = 19,140

A correlation coefficient of .89 indicates that _____.
Answers
The correlation coefficient indicates the strength of the relationship between variables. The closer it is to 1, the stronger the relationship. If it is 0, there is no relationship.
Explanation:The number portion of the correlation coefficient indicates the strength of the relationship. The closer the number is to 1 (be it negative or positive), the more strongly related the variables are, and the more predictable changes in one variable will be as the other variable changes. The closer the number is to zero, the weaker the relationship, and the less predictable the relationships between the variables becomes. For instance, a correlation coefficient of 0.9 indicates a far stronger relationship than a correlation coefficient of 0.3. If the variables are not related to one another at all, the correlation coefficient is 0.

if a population of scores is normally distributed, has a mean of 45 and a standard deviation of 6, the most extreme 5% of the scores lie beyond the score(s) of _________.
a. 35.13
c. 56.76 and 33.24
b. 45.99
d. 45.99 and 35.13
Answers
Final answer:
To find the most extreme 5% of normally distributed scores with a mean of 45 and a standard deviation of 6, we look for scores beyond the z-score cut-offs corresponding to 2.5% and 97.5%. The z-score around 1.96 gives us two scores: 56.76 on the high end and 33.24 on the low end, indicating that answer 'c' is correct.
Explanation:
To determine the most extreme 5% of the scores in a normally distributed population with a mean of 45 and a standard deviation of 6, we need to find the z-score that corresponds to the tails of the distribution where the cumulative area is either less than 2.5% or greater than 97.5% (since 5% is split into two tails of the distribution).
Using a standard normal distribution table or a calculator, the z-score that corresponds to the upper 97.5% is typically about 1.96 (or sometimes 1.645 for a one-tailed test). To find the actual scores corresponding to these z-scores, we use the formula for transforming a z-score into an actual value which is:
X = μ + (z • σ)
For the upper extreme:
X = 45 + (1.96 • 6) = 56.76
For the lower extreme:
X = 45 - (1.96 • 6) = 33.24
Thus, the most extreme 5% of the scores lie beyond scores of 56.76 and 33.24. Therefore, the correct answer is c. 56.76 and 33.24.
