Mario has captured many yellow-spotted salamanders. He weighs each and then counts the number of yellow spots on its back. This trend line is a fit for these data A. Weak B. Negative C. Parabolic D. Strong
The trend line is a strong fit for the data on yellow-spotted salamanders.
What is a trend line?A graph can be described as a pictorial representation of data. A trend line is used to show the direction of the data plotted. The trend line shown is positive. This means that as the number of spots increases, the weight of the salamander increases. The trendline is strong because most of the dots lie along the trendline.

the line plot is entitled weight of science books in pounds. it goes from 2 pounds to 3 pounds with marks at some numbers:
one mark is at two and one eighth. two marks are at two and one fourth. one mark is at two and three eighths. two marks are at two and one half. three marks are at two and three fourths. one mark is at two and seven eighths. question
sonya carried ,begin emphasis,all,end emphasis, the books weighing 2 and one-fourth pounds and 2 and three-eighths pounds to the library. how many pounds of books did sonya carry?
The total pounds of science books that sanya carried is; 6⁷/₈ pounds
How to Interpret Line Plots?
From the attached Line Plot, we can see the book weights.
Now, we are told that Sanya carried all the books weighing 2¹/₄ pounds and 2³/₈ pounds.
From the line plot we see that;
Number of books weighing 2¹/₄ pounds are 2 books
Number of books weighing 2³/₈ pounds is 1 book
Thus;
Total weight of books carried by Sanya = 2(2¹/₄) + 1(2³/₈)
Total weight = 4¹/₂ + 2³/₈
Total Weight = 6⁷/₈ pounds

Bob bikes to work 8 miles each day. The trip takes him 0.5 hours. If Bob bikes at a constant rate, what is his biking speed? A. 5 mph B. 8 mph C. 16 mph D. 40 mph
Given the distance covered and the time elapsed, if the bike is at a constant rate, the speed of Bob's bikes is 16 mph.
Option C) is the correct answer.
What is Speed?Speed is simply referred to as distance traveled per unit time.
Mathematically, Speed = Distance ÷ time.
Given the data in the question;
Distance covered d = 8milesTime elapsed t = 0.5hrsSpeed of the bike S = ?Speed = Distance ÷ time
Speed = 8miles / 0.5hrs
Speed = 16 mph
Therefore, Given the distance covered and the time elapsed, if the bike is at a constant rate, the speed of Bob's bikes is 16 mph.
Option C) is the correct answer.

The price of a notebook is 20% less than the price of a book. By
what percent is the price of the book higher than the price of the
notebook?
HELP
Answer:
125%
Step-by-step explanation:
lets just say the book is $100. 20% less would be $80
now to go back to $100, we need to add $20 to $80
20 is 25% of 80, so add the extra 25% to 100% of 80
2. What is the circumference of the circle?
e) 26π cm²
g) 6767 cm²
f) 52π cm²
h) 1697 cm²
Answer:
26π cm
Step-by-step explanation:
the circumference (C) of a circle is calculated as
C = πd ( d is the diameter )
= π × 26
= 26π cm
▶︎◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◀︎
[tex]Hello[/tex] [tex]There![/tex]
We are looking for the circumference of the circle.
It's not hard, I promise! I will take you through a few steps, and we'll find the answer.
Are you ready? Then let's begin...:)
[tex]Procedure:[/tex]
First, we need a formula for the circumference. We can't find the circumference without a formula!
· Luckily, there is a formula for the circumference:
⇒ [tex]C=\pi d}[/tex]
Whoa. What's that?!
No worries, I'll clarify everything in a moment. :)
We are looking for the circumference.
In this formula, what stands for the circumference?
That's right, [tex]C[/tex].
Now, what is this: [tex]\pi[/tex]?
This letter stands for pi - a constant in maths that comes in handy when we're searching for the circumference of a circle (or area).
It has an infinite number of digits after the decimal point, and these digits never repeat!
You might be thinking, "Oh no! Are we really going to use that infinite number?!"
The answer is "No". Mostly, we use 3.14 for [tex]\pi[/tex], because these are the first three digits of pi, but since we aren't asked to use 3.14 for pi, we just press the [tex]\boxed{\pi }[/tex] button on our calculator.
Whew!
And then last but not least, we see "d". This isn't a constant, this is the diameter.
Checking our provided information, we see that the diameter is 26 cm.
Now, we substitute 26 for d:
[tex]\bold{C=\pi (26)}[/tex]
[tex]\bold{C=\pi *26}[/tex]
And now all we have to do is type these numbers into our calculator, and find the answer:
[tex]\bold{C\approx81.7\:cm}[/tex]
Hooray! We've found the circumference!
But wait - why isn't 81.7 an option?
Because what we need to do is write it in terms of pi, which is even easier, because we just substitute 26 for d:
[tex]\bold{C=\pi *26}[/tex]
➢ Rearrange the order of the terms:
[tex]\bold{C=26\pi \:cm}[/tex]
▲ Circumference
Now there's another thing - why are all four options with units squared?
Circumference isn't measured in units squared, the area is!
▶︎ Incase you need the area, here it is:
[tex]\bold{A=\pi r^{2}}[/tex]
A=Area (what we're looking for)
[tex]\pi[/tex] = pi
Here we have a new variable - it's r, which is the radius.
Do you see that [tex]^2[/tex] next to r? It means that r is squared, or multiplied by itself.
You might be thinking, "But we don't have the radius!"
If we have the diameter, finding the radius is a piece of cake, because we divide the diameter by 2:
[tex]\bold{26\div2}[/tex]
[tex]\bold{13}[/tex]
Now we substitute 13 for r and evaluate:
⇒ [tex]\bold{A=\pi (13)^{2}}[/tex]
13 times itself is 169:
⇒ [tex]\bold{A=169\pi \:cm^{2}}[/tex]
Whew! We're finally done!
hope it's helpful!wishing you a great day!
[tex]Greetings![/tex]

What is ∑n=15[5(−2)n−1] equal to?
Answer:
Although the notation is sloppy, I will assume based on former questions of the same that "∑n=15[5(−2)^n−1]" translates mathematically to . Please correct me, though, if this in incorrect.
Anyway, there is neat formula that will deal with question very quickly. It is the following:
Sn is the sum of the geometric series
a1 is the first term in the series
r is the common ratio
n is the number of terms in the finite geometric series
Let's use this formula to our advantage! However, there are two variables that we do not know: a1 and n. Let's start with a1.The first term in the series is when n=1, so let's determine what that is.
The expression ∑n = 15 [5 (−2) n − 1] is equal to 5/16384.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
First, let's understand the notation.
∑n = 15 represents the sum of the expression that follows for n starting from 15, and the expression is 5 (−2) n − 1.
So, we need to find the sum of 5 (−2) n − 1 from n = 15 to n = 15, which means there is only one term in the sum.
Substituting n = 15, we get:
5 (−2) (15 − 1) = 5 (−2) 14 = 5/16384
Therefore,
The expression ∑n = 15 [5 (−2) n − 1] is equal to 5/16384.
