Answers
The probability of that the first 40 feet in a roll contain no flaws is ≈ .3012
What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
CalculationΘ = μ = [tex]\frac{100 foot}{3 flaws}[/tex]
a ) We assume that the length until the first flaw follows an exponential distribution.
Probability density function of exponential distribution:
f(x) = [tex]\frac{1}{Θ} e^{\frac{-x}{Θ} } = \frac{1}{100/3}e^{-x/(100/3)} = \frac{3}{100}e^{-3x/100}[/tex]
The first 40 feet in a roll of 100 feet contain no flaws if the first flaw occurs after 40 feet.
The probability is the integral over the corresponding interval:

A table is made using the following two patterns.
Pattern x: Starting number: 3, Rule: add 3
Pattern y: Starting number: 6, Rule: add 6
Complete the table for the given patterns.
And then it asks to graph the points from 3 points
Answers
The rules of the patterns are 3 + 3x and 6 + 6y
How to complete the pattern?The patterns are given as:
Pattern x: Starting number: 3, Rule: add 3Pattern y: Starting number: 6, Rule: add 6For pattern x, we have the following highlights:
Start = 3
Rule = Add 3
This means that the nth term of pattern x is:
Pattern x = 3 + 3x
For pattern y, we have the following highlights:
Start = 6
Rule = Add 6
This means that the nth term of pattern y is:
Pattern y = 6 + 6y
The complete tableFor pattern x, set x = 0, 1, 2 and 3
So, we have
3 + 3x = 3 + 3(0) = 3
3 + 3x = 3 + 3(1) = 6
3 + 3x = 3 + 3(2) = 9
3 + 3x = 3 + 3(3) = 12
For pattern y, set y = 0, 1, 2 and 3
So, we have
6 + 6x = 6 + 6(0) = 6
6 + 6x = 6 + 6(1) = 12
6 + 6x = 6 + 6(2) = 18
6 + 6x = 6 + 6(3) = 24
Next, we plot the graphs of both patterns (see attachment) where the blue line represents pattern 1, and the other represents the second pattern

For a project in his Geometry class, Yusuf uses a mirror on the ground to measure the
height of his school building. He walks a distance of 10.25 meters from the building,
then places a mirror flat on the ground, marked with an X at the center. He then
walks 1.65 more meters past the mirror, so that when he turns around and looks
down at the mirror, he can see the top of the school clearly marked in the X. His
partner measures the distance from his eyes to the ground to be 1.55 meters. How tall
is the school? Round your answer to the nearest hundredth of a meter.
Answers
Step-by-step explanation:
sadly we don't know anything about the size of the mirror on the ground, or if e.g. the 1.65 m from the mirror mean from the edge of the mirror or from the x at the center of the mirror.
so, we must assume the mirror as a dot without any significant lengths in the calculation.
we have 2 right-angled triangles.
1. the small one : from Yusuf's eyes to the ground at his feet to the x on the mirror on the ground.
2. the large one : from the top of the building to the bottom of the building on the ground to the x on the mirror on the ground.
the mirroring creates a dilation from the large triangle to the small triangle through the point x on the mirror.
in other words, all the angles stay the same, and there is one constant scale factor for all the lengths of one triangle to the other, making both triangles similar.
that means that the scale factor "f" of the ground distances from the small to the large triangle is
10.25 / 1.65 = 1025 / 165 = 6 35/165 = 6 7/33 =
= 6.212121212...
the scaling from Yusuf's height (well, his eye level) to the height of the school must follow the same ratio :
school height / Yusuf's eye level =
= h/1.55 = 10.25/1.65
h = 10.25 × 1.55 / 1.65 = 1025 × 155 / 16500 =
= 9.628787879... m ≈ 9.63 m
the school is approximately 9.63 m tall.
FYI : this is the same principle as with a camera. the lens (and the mirror inside if applicable) create a dilated "projection" onto a film or an array of digital light sensors, so that the captured image retains all the angles and all the length ratios of the original.
but to know from the picture e.g. how tall the original was, we need to know also the distance from which the picture was taken. otherwise this can't be answered.
solve each linear equation 7+2x=4x-3
Answers
Answer:
Simplifying
7 + 2x = 4x + -3
Reorder the terms:
7 + 2x = -3 + 4x
Solving
7 + 2x = -3 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
7 + 2x + -4x = -3 + 4x + -4x
Combine like terms: 2x + -4x = -2x
7 + -2x = -3 + 4x + -4x
Combine like terms: 4x + -4x = 0
7 + -2x = -3 + 0
7 + -2x = -3
Add '-7' to each side of the equation.
7 + -7 + -2x = -3 + -7
Combine like terms: 7 + -7 = 0
0 + -2x = -3 + -7
-2x = -3 + -7
Combine like terms: -3 + -7 = -10
-2x = -10
Divide each side by '-2'.

area: 1641.6 square inchesperimeter: 168.8 inchesStep-by-step explanation:
You want the area and perimeter of a rectangle that is 54 inches in length and 30.4 inches in width.
AreaThe area formula is ...
A = bh
We can use the length as the "base" and the width as the "height", so we have ...
A = (54 in)(30.4 in) = 1641.6 in²
The area of the television screen is 1641.6 square inches.
PerimeterThe perimeter of a rectangle is given by the formula ...
P = 2(L +W)
Using the given length and width, the perimeter is found to be ...
P = 2(54 in + 30.4 in) = 2(84.4 in) = 168.8 in
The perimeter of the television screen is 168.8 inches.
The area of the rectangular television screen is 1641.6 square inches and the perimeter of the television screen is 84.4 inches.
What is the area of a rectangle?
The area a rectangle occupies is the space it takes up inside the limitations of its four sides. The dimensions of a rectangle determine its area. In essence, the area of a rectangle is equal to the product of its length and breadth. Its area is the space that the rectangle's boundary encloses.
Mathematically, area of a rectangle = length * width = l * w
What is the perimeter of a rectangle?
The perimeter is defined as the sum of all sides of the rectangle. Mathematically, perimeter of a rectangle = 2(length + width) = 2*(l + w)
Given, the length of the television screen = l = 54 inches
The width of the television screen = w = 30.4 inches
Using the formula mentioned in the literature above,
Area of the television screen = l * w = 54*30.4 = 1641.6 square inches
Also, perimeter of the television screen = l + w = 54 + 30.4 = 84.4 inches
Thus, the area of the rectangular television screen is 1641.6 square inches and the perimeter of the television screen is 84.4 inches.

From the question, we were told that Garcia's bike rentals cost $38 to rent bike for 9 hours.
We are to find how many hours will a customer use the bike per dollar.
This can also be likened to calculating miles per gallon.
if i can drive 300 miles on 10 gallons of gas then my miles per gallon is 300/10 = 30 mpg.
So, hours per dollar is also a division problem too.
(9 hours)/($38)
= 9/38
= 0.2368
= 0.24 hours per dollar (to the nearest hundredth)
