A wildlife biologist catches and releases 20 fish from two different lakes at random locations. He catches 10 fish at Lake Palmer and 10 fish at Lake Dalton. He measures the length of each fish to the nearest quarter of an inch. Palmer Dalton First Quartile 6.75 5.5 Second Quartile (Median) 10.25 6.75 Third Quartile 13 7.5 Based on the samples, what generalization can be made? A. Not enough information is provided to draw any of these conclusions. B. The first quartile value at Lake Palmer is 1.25 inches longer than the first quartile value at Lake Dalton. C. The interquartile range for Lake Dalton is 2 inches greater than the interquartile range for Lake Palmer. D. At least 25 percent of the fish in both lakes are no longer than 6 inches
Please put the correct answer, if it's correct i will mark with the crown and give a good rating
Thanks!
Option B is the correct answer, as it correctly states that the first quartile value of fish lengths at Lake Palmer is 1.25 inches longer than that of Lake Dalton.
Explanation:The question provides quartile data for fish lengths caught in two different lakes and asks to generalize the findings based on the provided information. First, let's analyze the provided options:
Option B: Incorrect, because the difference between the first quartiles of Lake Palmer (6.75 inches) and Lake Dalton (5.5 inches) is 1.25 inches, hence true.Option C: Incorrect, because the interquartile range (IQR) for Lake Dalton (7.5 - 5.5 = 2 inches) is not 2 inches greater than the IQR for Lake Palmer (13 - 6.75 = 6.25 inches).Option D: Incorrect because at least 25 percent of the fish in Lake Dalton are no longer than 5.5 inches, and at least 25 percent of the fish in Lake Palmer are no longer than 6.75 inches. Hence, not all fish in both lakes are no longer than 6 inches.Therefore, the correct generalization can be made from Option B. It provides accurate comparison based on the first quartile values of fish lengths in both lakes.
Circle O is inscribed in the given triangle. What is the perimeter of the triangle?
Answer:
44 units
Step-by-step explanation:
just answered on edg 2020
When a circle is inscribed in a triangle, its radius is equal to the distances between the points of tangency on each side and the center of the circle.
Explanation:When a circle is inscribed in a triangle, it is tangent to all three sides of the triangle.
The perimeter of the triangle can be found by adding the lengths of the three sides.
Since the circle is inscribed in the triangle, the lengths of the sides of the triangle are equal to the distances between the points of tangency on each side and the center of the circle.
Therefore, the perimeter of the triangle is equal to the sum of these distances.

Write an equation of the line that passes through the points (0,4) and (2,10).
Answer:
First you find the slope:
(10-4)/2 = 6/2 = 3
Then you write a point-slope equation:
y-4=3x
in slope-intercept form:
y=3x+4
Answer:
The equation of the line is y = 3x + 4.
Step-by-step explanation:
First find the slope of the line:
Slope (m) = rise / run
= difference in y coordinates / difference in corresponding x coordinates
= (10-4) / (2 - 0)
= 6/2
= 3..
The line is written as
y = m x + b
We have just found m (= 3). Now we find the value of b by substituting the point (0, 4) into this equation.
4 = 3(0) + b
b = 4.
So the required equation is y = 3x + 4.

Parallel Lines never intersect
because...
Step-by-step explanation:
Well, they don't intersect because that's how they're defined. If they were to intersect then they wouldn't be considered parallel lines.
Parallel lines never intersect because they are always equidistant from each other, meaning they maintain the same distance apart at every point along their length.
What are parallel lines?If the two original lines are parallel, then these two angles must be equal, since they are corresponding angles. However, if we extend the third line far enough, the angles will eventually add up to more than 180 degrees, which is impossible in a Euclidean plane. Therefore, the third line cannot intersect the two parallel lines, and they will never meet.
Consider two lines in a two-dimensional plane. If they are parallel, they will never cross each other no matter how far they extend. Imagine drawing a third line that intersects both of them at some point. This will create two angles where the two lines meet the third line, forming a triangle.
This property of parallel lines has many practical applications in fields such as engineering, architecture, and mathematics, where parallel lines are used to create accurate drawings and models of structures and systems.

Find the slope of the line through the points (4, -1) and (-2, -1).
To find the slope (m), use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] And plug in the two points
(-2, -1) = (x₁, y₁)
(4, -1) = (x₂, y₂)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{-1-(-1)}{4-(-2)}[/tex] (two negative signs cancel each other out and become positive)
[tex]m=\frac{-1+1}{4+2}[/tex]
[tex]m=\frac{0}{2}[/tex]
m = 0
Answer:
The slope is 0.

A spinner has 10 equal-sized sections. Two of the sections are red.
a. What is the probability that the spinner will land on red?
b. Use words to describe the probability.
Answer:
a. Probability of landing on red = [tex]\frac{1}{5}[/tex]
b. See Explanation
Step-by-step explanation:
Given
A Spinner
Number of section = 10 (equal sized)
Number of red section = 2
Required
- Probability of landing on red
- Describe the probability in words
Calculating the probability of landing on red
The formula used in calculating probability is as follows
Probability = Number of required outcomes / Number of possible outcomes
In this case, the number of required outcomes is the number of red section.
Hence, number of required outcomes = 2
And the number of possible outcomes is the total section of the spinner
Hence, Number of possible outcomes = 10
By Substitution
Probability of landing on red = [tex]\frac{2}{10}[/tex]
Probability of landing on red = [tex]\frac{1}{5}[/tex]
Describe the probability in words
From (a) above, we have that the probability of the spinner landing on color red is [tex]\frac{1}{5}[/tex]
This means that, for every five times, you spin the spinner, it's likely that one of the outcomes will be red.

For example, if I say, (2,5) is a solution to the equation y= 2x+3, how could you check my claim?

What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b
We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).
If the area he paces divided by the area his apprentice paces equals three, then we can write it as;
J/a = 3
In ratio form,
J : a = 3 : 1
Where J. represent Harry and. a represent the apprentice. Hence,
Therefore, the area Harry will pace;
= ( 3/4) × 140 ft.²
= 105 ft.²

How to solve 17 = x/2 + 1
Answer:
x = 32
Step-by-step explanation:
17 = x/2 + 1
17 - 1 = x/2
16 = x/2
16 / 1/2 = x
16 * 2/1 = x
32 = x
Answer:
x = 32
Step-by-step explanation:
to solve for this expression 17 = x/2 + 1 , we need to collect the like terms and then evaluate for the value of x.
solution
17 = x/2 + 1
17 - 1 = x/2
16 = x/2
using cross multiplication method
x = 16 x 2
x = 32
Twenty gremlins and fifteen imps are at the Annual Mischief Convention. The imps have had a lot of in-fighting lately and refuse to shake hands with each other, but they readily shake hands with all of the gremlins. Meanwhile, all the gremlins are quite friendly and shake hands with all of the other gremlins as well as imps. Each pair of creatures shakes hands at most once. How many handshakes were at the convention?
Answer:
490
Step-by-step explanation:
Let us first count the handshakes between two gremlins. There are 20 gremlins, so there must be 20*19/2=190 handshakes between two gremlins, making sure to divide by two to avoid over-counting.
There are 15 imps that shake hands with each of the 20 gremlins, which makes 15* 20 = 300 handshakes between imps and gremlins.
Adding these up, you have $300 + 190 = 490 total handshakes.
