A bag contained 18 red marbles, 14 green marbles, and 20 blue marbles. A marble was randomly pulled, the color recorded, and then put back into the bag. This table above shows the results after 25 pulls.
What was the relative frequency of selecting a red or blue marble?
Red:8
Blue8
Green9
Number of red marbles pulled = 8
Number of blue marbles pulled = 8
Total marbles pulled = 25
Relative Frequency = Total Frequency / Total number of data values
Relative Frequency of red marble = 8/25
= 32%
Relative Frequency of blue marble = 8/25
= 32%

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

1. A light bulb is one-hundredth of an inch thick, with an allowable error of 2%. What is the least allowable thickness of the filament?
A. 0.00098
B. 0.0002
C. 0.0098
D.0.0102
Answer:
Answer:
0.00998 Inches
Step-by-step explanation:
Thickness of the light bulb filament = 0.01 Inch
Allowable error = 2%.
2% of 0.01 = 0.02 X 0.01 =0.0002 Inch
Therefore, the allowable thickness of the bulb filament
We can then calculate the least allowable thickness of the filament as:
The least allowable thickness of the filament is 0.00998 Inches.
Answer:
C. 0.0098
Explanation:
one-hundredth of an inch: 1/100 ≈ 0.01 (inch)
Upper-bound (maximum error):
= 0.01 × (100% + 2%)
= 0.01 × 102%
= 0.0102 inches
Lower-bound (minimum error):
= 0.01 × (100% - 2%)
= 0.01 × 98%
= 0.0098 inches
Hence, the greatest allowable thickness of filament is 0.0102 inches and mostly the least allowable thickness is 0.0098 inches, which is the answer.

1. How many arcs did we create when we bisected a line?
2. What are the two Euclidean tools?
3. What is a line that divides a given line segment exactly into two halves forming 90 degrees angle at the intersection point?
4. What are the three parts of a compass that are discussed earlier?
5. What is the midpoint of line segment AB and line segment PQ?
6. What's the sign for intersecting lines?
7. What's the sign for parallel lines?
8. The compass and straightedge are known as?
9. What bisector divides a given angle into two angles of equal measures?
10. Why is it important to construct and bisect them step by step?
When a line is bi sected, it creates two arcs. The two Eu.c.li dean tools are the compass and straight edge. The line that divides a given line segment exactly into two halves forming a 90° angle at the intersection point is called the perpendicular bi sector.
What are the responses to other questions?The three parts of a compass are the h i n g e, the pencil or pen, and the adjustment s c r e w. The midpoint of a line segment AB is the point that is equidistant from A and B. The midpoint of a line segment PQ is the point that is equidistant from P and Q.
The sign for intersecting lines is an X at the point of intersection. The sign for parallel lines is two vertical lines that are equidistant and never intersect. The compass and straight edge are known as E.u.c.l.i dean tools. The bisector that divides a given angle into two angles of equal measures is called the angle bisector.
It is important to construct and bisect them step by step because it ensures accuracy and precision in the construction. Following a systematic approach helps to avoid errors and allows for easy replication of the construction.

How many times does 15 go int 135? who ever gets it right gets 500 points
Answer:
9 times
Step-by-step explanation:
The number 15 multiplied to the number 9 which gives the value 135.
To find the that how many 15 is to get 135, division should be performed.
So, dividing 135 by 15 gives:
= 135 ÷ 15
15 | 135 | 9

Calculate the area of the annulus which has an external diameter of 25cm and an internal diameter of 15cm
Answer:
314.159 square cm
Step-by-step explanation:
Area of an annulus with external radius r1 and internal radius r2 is given by
π(r1² - r2²)
radius = half diameter
r1 = 25/2 = 12.5 cm
r2 = 15/2 = 7.5 cm
Area of annulus
= π(12.5² - 7.5²)
= 314.159 square cm
The correct answer is 314.159 square cm

Answer:
b. 2/3
Step-by-step explanation:
First, I multiplied all of the values to each other, to get the area^3 of the box.
With my answer, 4.73925, I used a longer method, and divided my answer by each answer displayed.
a-4.73925/1/3=12.21775
b-4.73925/2/3=7.108875
c-4.73925/1/2=9.4785
d-4.73925/1=4.73925
I didnt use the full answer from when I multiplied all the answers together, so the answer will be just hardly off a whole number. So, b should be the answer.
If the answers were side lengths, read below
First, I multiplied all of the values to eachother, to get the area^3 of the box.
With my answer, 4.73925, I used a longer method, and divided my answer by each answer displayed, after I cubed them.
