( marking right as brainliest and 5.0 star! ) Seaira measures and records the lengths, in feet, of 9 lizards. The line plot below shows the information she records, based on the line plot what is the difference between the lengths in feet, of the longest lizards and the shortest lizards?
Answers
Based on the line plot, the shortest lizard is 2 feet long and the longest lizard is 7 feet long. Therefore, the difference between the lengths of the longest and shortest lizards is 5 feet.
The line plot indicates that the shortest and longest lizards are each 2 feet long. As a result, there are 7 - 2 = 5 feet between the longest and shortest lizards in terms of length.
A line plot is a graph that displays data using X's above a number line to represent the frequency of each value. In this case, the line plot shows the lengths of the 9 lizards that Seaira measured.
A line plot, commonly referred to as a dot plot, is a straightforward graphical data display that shows distinct data points along a number line. It is frequently used to display the frequency and distribution of a set of data. A mark or dot is placed above the relevant value on the number line to symbolise each data point. Line plots offer a visual representation of the data's central tendency and variation and are especially helpful for small data sets. They enable fast data analysis, allowing for the detection of outliers, clustering, and discrepancies in the data distribution.

FILL IN THE BLANK. to determine the proportion of each color of Peanut Butter M&Ms, you buy 10 1.69 ounce packages and count how many there are of each color. This is an example of ______
Answers
This is an example of a sample survey or a sampling method.
What is sampling method?Sampling techniques in a statistical study refer to how participants are chosen from the population to participate in the study. If a sample isn't chosen at random, it will likely be skewed in some way, and the results might not be generalizable.
In the given scenario, you are conducting a sample survey to determine the proportion of each color of Peanut Butter M&Ms. A sample survey is a method used to collect data from a subset of a larger population in order to make inferences about the entire population.
Instead of counting every single Peanut Butter M&M in existence, which would be impractical and time-consuming, you decide to take a smaller representative sample. You purchase 10 packages of Peanut Butter M&Ms, each weighing 1.69 ounces, and count the number of M&Ms of each color in those packages.
By analyzing the data collected from this sample, you can estimate the proportion of each color of Peanut Butter M&Ms in the larger population. This approach is more feasible and provides a reasonable approximation of the overall distribution of colors without having to examine every individual item.

find the value of X, y and z
ans: x=50 y= 50 z=50
Answers
The value of x , y and z in the parallel line is 50 degrees.
How to find the angle in parallel line?When parallel lines are crossed by a transversal line, angle relationships are formed such as vertically opposite angles, alternate interior angles, alternate exterior angles, adjacent angles, corresponding angles etc.
Therefore, let's use the angle relationships to find the angle, x, y and z as follows:
Therefore,
x = 360 - 310(sum of angles in a point)
x = 50 degrees
Therefore,
x = y(alternate interior angles)
Alternate interior angles are congruent.
Hence,
y = 50 degrees
Therefore,
x = z(alternate interior angles)
z = 50 degrees.

the box is to be filled with sand. which measure would be used to find the amount of sand the box will hold?
Answers
To find the amount of sand that a box will hold, we would use the measure of volume.
Volume is the amount of space that an object or substance takes up in three dimensions, typically measured in cubic units. In the case of the box being filled with sand, we would use the volume of the box to determine how much sand it can hold. This can be calculated by multiplying the length, width, and height of the box together, which gives the total cubic units of volume. The resulting value would be in cubic units such as cubic inches, cubic feet, or cubic meters, depending on the units of measurement used.

Answers
Answer:
ans 3
Step-by-step explanation:
Circumference is distance round a figure. When diameter is trippled, the circumference will also tripple.
Here is a proof
Take the moon to have circular shape and has diameter d
Circumference is given by C=πd
When the new diameter is trippled, diameter will be 3d and the new circumference will be
C=π3d=3πd
Evidently, the new circumference is three times the original circumference. Therefore, for this case, the new circumference will be 3 times the original

The lengths of the sides of a triangle are given. Classify each triangle as acute, right, or obtuse.
7.) 4, 5, 6
8.) 11, 12, 15
9.) 30, 40, 50
Answers
The given triangles are obtuse = 36 m, right angled = 225 m and right angled = 2500 m.
What is Triangle?Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.
7.) This triangle is obtuse.
To see this, we can use the Pythagorean theorem:
4*4 + 5*5 = 16 + 25 = 41
6*6 = 36 m
Since 41 > 36, we know that the triangle is obtuse.
8.) This triangle is right.
To see this, we can again use the Pythagorean theorem:
11*11 + 12*12 = 121 + 144 = 265
15*15 = 225 m
Since 265 = 225 + 40, we know that the triangle is right.
9.) This triangle is also right.
We can use the same method as before:
30*30 + 40*40 = 900 + 1600 = 2500
50*50 = 2500 m
Since 2500 = 2500, we know that the triangle is right.
Therefore, The given triangles are obtuse , right angled and right angled.

Step-by-step explanation:
Total possibility:
All the 5 books can be arranged in a rack with P(5,5)=5! ways
Favorable Possibility:
Math book is kept in a first place, it mean that it is fixed
So remaining 4 books and that can be arranged in P(4,4)=4! ways

Probability= number of favorable cases / total number of possibilities
Probability = P(4,4) / P(5,5) = 4! / 5! = 1/5

What is quadrilateral?A quadrilateral is a four-sided polygon. The sum of the interior angles of a quadrilateral is always equal to 360 degrees. There are several types of quadrilaterals, including: Square, rectangle, parallelogram, rhombus, trapezoid, and kite.
Length of side PS can be calculated using the distance formula,
\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
Where,
P(-2, 5) = (\(x_1,y_1\)) (the coordinate of P is gotten from the graph).
Given that,
S(9, 5) = (\(x_2,y_2\))
PS = \(\sqrt{(9-(-2))^2+(5-5)^2}\)
PS = \(\sqrt{11^2+0^2}\)
PS = \(\sqrt{121}\)
PS = 11units.
Thus, the answer is 11 units.

Matthew and Guadalupe are reading the same book. At the beginning of the month,
Matthew was on page 21 and Guadalupe was on page 42. Matthew will read 18 pages
per day and Guadalupe will read 11 pages per day. Let M represent the page of the
book that Matthew is on at the end of t days into the month, and let G represent the
page of the book that Guadalupe is on at the end of t days into the month. Write an
equation for each situation, in terms of t, and determine what page Matthew and
Guadalupe will be on on the day they are both on the same page.
M=?
G=?
Answer: Page?
Answers
The equations are:
M = 21 + 18t
G = 42 + 11t
The page they would be on is 75 pages.
What pages would they be on?The linear equation that represents the total number of pages read by each person at day t, is :
Total pages read = pages read at the beginning of the month + (number of pages read per day x number of days)
Total pages read by Matthew = 21 + (18 x t)
= 21 + 18t
Total pages read by Guadalupe = 42 + (11 x t)
= 42 + 11t
When they are on the same page, the two above equations would be equal:
21 + 18t = 42 + 11t
18t - 11t = 42 - 21
7t = 21
t = 21 / 7
t = 3 days
Page they would both be on = 21 + 18(3)
