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.
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.

Which is the greatest?
5/100 5/10 24/1000
Answer:
5/10
Step-by-step explanation:
To solve this problem we find equivalent fractions with the same denominator:
The LCM of 10,100 and 1000 is 1000. So we make all the denominators 1000:
5/100 = 50/1000
5/10 = 500/1000
24/1000 = 24/1000
Now we compare the numerators and see which is the largest number.
24 < 50 < 500
So 5/10 must be the greatest.

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
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

Suppose that the functions r and s are defined for all real numbers x as follows.
r(x)=3x+5
s(x)=4x
Write the expressions for (r-s)(x) and (r*s)(x) and evaluate (r+s)(-2).
A function assigns the values. The value of (r+s)(-2) is equal to 9.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the function r(x)=3x+5, while s(x)=4x, therefore, the expressions can be written as,
(r-s)(x) =r(x)-s(x) = 3x+5 - 4x = -x+5
(r*s)(x) = r(x)·s(x) = (3x+5)·(4x) = 12x² + 20x
The expression for (r+s)(x) can be written as,
(r+s)(x) = r(x)+s(x) = 3x+5+4x = 7x+5
(r+s)(-2) = 7(-2)+5 = -14+5 = 9
Hence, the value of (r+s)(-2) is equal to 9.
