The population of a small town was 10,800 in 2002. Since then the population has decreased at a rate of 2.5% each year. Write an exponential function to model the situation then find the population of 2020
Answers
Answer:
See below
Step-by-step explanation:
A 2.5 % decrease means 97.5 % remains (.975)
population = 10800 ( .975) ^n where n = years past 2002
in 2020 n = 18
10800 (.975)^18 = 6847 people
Padma has room to line up 8 figurines in a display case how many different ways can she arrange the figurines in the display case? Enter your answer in the box
Answers
Answer:
it can be arranged in 40320 ways
Step-by-step explanation:
this is simply permutation,
so the ways of arrangement = 8!
=8×7×6×5×4×3×2×1
=40320
please mark brainliest:)
There are 40,320 different ways for Padma to arrange the 8 figurines in the display case.
What is the permutation?The permutation is defined as considered an ordered combination.
To determine the number of different ways Padma can arrange the 8 figurines in the display case, we can use the concept of permutations.
The number of permutations of n objects taken r at a time is given by the formula:
P(n, r) = n! / (n - r)!
In this case, Padma has 8 figurines, and she wants to arrange all of them in the display case, so r = 8.
P(8, 8) = 8! / (8 - 8)!
Simplifying:
8! / 0! = 8!
Calculating 8! (8 factorial):
8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40,320
Therefore, there are 40,320 different ways for Padma to arrange the 8 figurines in the display case.

A particular fruit's weights are normally distributed, with a mean of 615 grams and a standard deviation of 10 grams.
The heaviest 10% of fruits weigh more than how many grams?
Give your answer to the nearest 0.1 gram.
Answers
The heaviest 10% of fruits weigh more than 814.79 grams.
The problem setup implies that the weight of this fruit is a random variable when it says a particular fruit's weights are normally distributed.
What are the formula weights are normally distributed?Define X = Random Variable of the fruit's weight
[tex]X \sim N(mean = 760, standard deviation = 39)[/tex]
We want to find the specific gram value for which 8% of the fruits are heavier
The 92nd percentile of X's normal distribution
[tex]Solve for x: Pr( X < x ) = Normal( 760, 39 ) CDF = .92[/tex]
Standardizing we obtain
[tex]Pr( [X - 760]/39 < [x - 760]/39 ) = Pr( Z < [x - 760]/39 ) = .92,[/tex]
where Z is a standard normal random variable
[tex]Pr( Z < [x - 760]/39 ) = Standard \ Normal \ CDF( [x - 760]/39 )[/tex]
==> Set this equal to .92:
[tex]Standard \ Normal \ CDF( [x - 760]/39 ) = .92[/tex]
Then, from the standard normal table:
[tex][x - 760]/39 = Inverse Standard Normal[/tex]
[tex]CDF( .92 ) = 1.405[/tex]
Use algebra to solve for x:
[tex]x = 39 * 1.405 + 760 = 814.795[/tex]
Therefore the heaviest 10% of fruits weigh more than 814.79 grams.

What is the volume of the following rectangular prism? 1 3/4 units
1/2 units
Answers
7/8 or 0.88
Explanation :-Just recall the formula for the volume of a prism: area of the base times its height. Now, is common to associate the base of a prism to the side which serves as a ‘‘base’’, i.e., the one in the bottom from our perspective.
This formula is right, but not quite precise. A better formulation for the formula would be: ‘‘the volume of a rectangular prism is equal to the area of a side times its relative height’’. Notice that we only need to rotate a prism to have a different side as a basis.
In the figure we have that the area of the green side is 1/2, and its relative height is 1 3/4. Thus, its volume is

C. (5/2, 4/3)
Step-by-step explanation:
The system of equations that are given are:
[tex]3x + 5y = 14[/tex][tex]6x - 4y = 9[/tex]To solve, let's use the substitution method.
Note: The substitution method for solving two-order systems involves solving one equation using the terms of the other equation.See Below:
So solving by substitution:
// Solve equation [2] for the variable x
[2] 6x = 4y + 9 [2] x = 2y/3 + 3/2// Plug this in for variable x in equation [1]
[1] 3•(2y/3+3/2) + 5y = 14 [1] 7y = 19/2 [1] 14y = 19// Solve equation [1] for the variable y
[1] 14y = 19 [1] y = 19/14// By now we know this much :
x = 2y/3+3/2 y = 19/14// Use the y value to solve for x
x = (2/3)(19/14)+3/2 = 101/42Therefore, the solution is:
[tex]{x,y} =\frac{101}{42} ,\frac{19}{14}[/tex]
