the number of fish in a lake decreasing by 400 every year,as described by the function below. f(1)=8200 f(n+1)=f(n)-400 what will be the value
The number of fish in the lake is an illustration of arithmetic sequence
The value of f(2) is 7800, and it represents the number of fish in the lake, the second year
The model is given as:
[tex]\mathbf{f(n+1) = f(n) - 400}[/tex]
Where [tex]\mathbf{f(1) = 8200}[/tex]
To calculate f(2), we simply take n as 1.
i.e. n = 1
Substitute 1 for n in [tex]\mathbf{f(n+1) = f(n) - 400}[/tex]
So, we have:
[tex]\mathbf{f(1+1) = f(1) - 400}[/tex]
Add 1 and 1
[tex]\mathbf{f(2) = f(1) - 400}[/tex]
Substitute 8200 for f(1)
[tex]\mathbf{f(2) = 8200 - 400}[/tex]
Subtract
[tex]\mathbf{f(2) = 7800}[/tex]
Hence, the value of f(2) is 7800

Answer:
46
240
Step-by-step explanation:
Substitute the given values for the variables, and evaluate the expressions.
1.
n = -5; m = 4
2n² - m = 2(-5)² - 4 = 2(25) - 4 = 50 - 4 = 46
2.
H = 60; Q = 40; V = 10
HQV/100 = (60)(40)(10)/100 = 6(4)(10) = 240
Answer:
46
240
Step-by-step explanation:
1) Put n = -5 and m = 4 into the equation, you'll then have;
2(-5)²-4
2(25)-4
50-4=46
2) Put H=60, Q=40 and V=10 into the equation, then you'll have that;
(60×40×10)/100

What is a negative z score and when would it be in your favor to have one?
Answer:
A positive z-score indicates that a particular value is greater than the mean, a negative z-score indicates that a particular value is less than the mean, and a z-score of zero indicates that a particular value is equal to the mean.
Step-by-step explanation:
Examples: Calculating a Z-Score
Suppose we have the following dataset that shows the height (in inches) of a certain group of plants:
5, 7, 7, 8, 9, 10, 13, 17, 17, 18, 19, 19, 20
The sample mean of this dataset is 13 and the sample standard deviation is 5.51.
1. Find the z-score for the value “8” in this dataset.
Here is how to calculate the z-score:
z = (X – μ) / σ = (8 – 13) / 5.51 = -0.91
This means that the value “8” is 0.91 standard deviations below the mean.
2. Find the z-score for the value “13” in this dataset.
Here is how to calculate the z-score:
z = (X – μ) / σ = (13 – 13) / 5.46 = 0
This means that the value “13” is exactly equal to the mean.
3. Find the z-score for the value “20” in this dataset.
Here is how to calculate the z-score:
z = (X – μ) / σ = (20 – 13) / 5.46 = 1.28
The negative z-score indicates that a particular value will be less than the mean.
What is a normal distribution?The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The z-score is given as
z = (x - μ) / σ
Where μ is the mean, σ is the standard deviation, and x is the sample.
The points regarding the z-score are as follows:
A positive z-score shows that a specific worth is more prominent than the mean.A negative z-score demonstrates that a specific worth is not exactly the mean.A z-score of zero shows that a specific worth is equivalent to the mean.The negative z-score indicates that a particular value will be less than the mean.

A farmer is measuring the average height y of her tomato plants x weeks after planting sprouts. What is the equation and slope.
The equation is y = 0.5x and the slope is 0.5.
A function is said to be linear if it is a straight line graph and it can be represented by the equation:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the height of the tomato after x weeks. Let us assume that the points are (0, 0) and (6, 3), hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{3-0}{6-0} (x-0)\\\\y=0.5x[/tex]
Therefore the equation is y = 0.5x and the slope is 0.5.

The equation for the scenario "A farmer is measuring the average height y of her tomato plants x weeks after planting sprouts" is y = mx + c
The slope = m
The duration after which the farmer measures the average height of her tomato = x weeks
The average height of the tomato plant after x weeks = y
For the slope to be required, it means the relationship between the average height of the her tomato (y) and the number of weeks (x) is linear
This means that the average height of the tomato will be represented by a linear equation as shown below
y = mx + c
The slope of the equation is m
