The Invasion of the Lionfish
What was once just an attractive aquarium fish has recently become one of the biggest menaces in the Atlantic. The lionfish was accidentally introduced into the Atlantic Ocean in the 1990s. Because it has no natural predators, it has adapted quickly to its new home. The lionfish now threatens to destroy native fish populations in the Atlantic, Caribbean, and Gulf of Mexico.
The lionfish spreads quite rapidly. Lionfish spread faster than any other invading species. Experts have called the invasion in the Atlantic the worst marine invasion of all time. The lionfish's success comes from an ability to reproduce all year round. In addition, they are greedy eaters with a fondness for small fish and crustaceans. They will eat anything smaller than they are. Lionfish love the warm waters of the Gulf of Mexico. Since their first sighting, they have rapidly multiplied. In some locations, scientists estimate that lionfish populations exploded by 700 percent between 2004 and 2008 alone.
To combat the invasion, wildlife agencies have sponsored lionfish derbies. In these derbies, local scuba divers are invited to harvest lionfish. In addition, many states offer recipes for preparing and eating lionfish to encourage harvesting. Lionfish have to be handled carefully because of their venomous spines, but they are apparently delicious. Increasing the harvest of lionfish will help. However, scientists estimate that more than a quarter of the population would have to be taken every month to stop the growing population.
The lionfish has targeted our most fragile and important ecosystems. Scientists are working tirelessly to learn as much as they can about this predator. We may never be able to completely remove the threat, but many fishermen and seafood fans are hoping we can figure out how to control it.

A line has a slope of zero. Which of the following points could this line pass through?
A.(-9, 7) and (9,-7)
B(1, 4) and (3,7)
C. (2,-5) and (6,-5)
D.(1, 2) and (10, 12)
Answer:
C
Step-by-step explanation:
slope 0 means same y
so C (y is -5 for both)
if my answer helps please mark as brainliest.
Answer:
C
Step-by-step explanation:
A line with slope of zero means that the y value doesn't change like the x axis. so we'll need to find points that even though they have different x values, they have the same y value. That. being said C is the answer

You can model an arch at your school using the equation $y=-0.5\left(x+4\right)\left(x-4\right)$ , where $x$ and $y$ are measured in feet. The x-axis represents the ground. Find the width of the arch at ground level.
Answer:
8feet
Step-by-step explanation:
Given the equation that models the arch of a school expressed as;
[tex]$y=-0.5\left(x+4\right)\left(x-4\right)$[/tex]
If the x axis represents the ground;
At the ground level, x = 0
Substitute x = 0 into the equation to get y;
y = -0.5(0+4)(0-4)
y = -0.5(4)(-4)
y = -0.5 * -16
y = 8ft
Hence the y axis at the ground level is 8feet

If m=2, then 5 - m(2) is 3, because 5 - 2 is 3.
A company has offices in two different countries. The 125 employees at location A have a mean commute time of 40 minutes and a standard deviation of 15 minutes. The 250 employees at location B have a mean and standard deviation of 35 and 10 minutes, respectively.
Every month, the company takes separate random samples of 20 employees from each location for a survey. Each time, they look at the difference in the mean commute time sampled from each location
Consider the formula: ...
Why is it not appropriate to use this formula for the standard deviation of ...
Choose
A. The samples are not independent of each other.
B. We cannot assume independence for the employees sampled from location A.
C. We cannot assume independence for the employees sampled from location B.
Answer:
B
Step-by-step explanation:
We cannot assume independence for the employees sampled from location A.
It is not appropriate to use this formula for the standard deviation of
A. The samples are not independent of each other.
What is the difference between the sample and the population?The entire group about whom you want to make conclusions is referred to as a population.
The particular group from which you will gather data is known as a sample. The sample size is always smaller than the population as a whole.
We cannot rely on the workers' sampled employees' independence.
Assuming independence based on the 10% condition requires at least 200 employees in the population with a sample size of 20, however, location A only has 125 employees.

x = (blank) degrees and adding letters so i can ask the question
Answer:
x = 47°
Step-by-step explanation:
Since CPD is a straight line, then
133 and x are adjacent angles and supplementary, sum to 180° , then
x + 133° = 180° ( subtract 133° from both sides )
x = 47°

Given the slope of the line containing the points (7 , b) and (-2 , 5) is 4/9, find the value of b
Answer: b=9
Step-by-step explanation: To find the slope we use: y2-y1/x2-x1
Which would then be: 5-b/-2-7= 5-b/-9
Then we have to find a number for b that would give us -4 as the numerator. That number would be 9
This would give us 4/9 which is the slope we already had.
