Step-by-step explanation:
Among fatal plane crashes that occurred during the past 55 years, 347 were due to pilot error, 83 were due to other human error, 596 were due to weather, 374 were due mechanical problems, and 114 were due to sabotage. Construct the relative frequency distribution.
Required:
What is the most serious threat to aviation safety, and can anything be done about it?
Answers
Answer:
Pilot error = 347 / 1487 = 0.233 = 23.3%
Other human error = 83 / 1514 = 0.055 = 5.6%
Weather = 596 / 1487 = 0.401 = 40.1%
Mechanical problem = 374 / 1487 = 0.233 = 23.3%
Sabotage = 114 / 1487 = 0.077 = 7.7%
Step-by-step explanation:
Given the data :
Pilot error = 347
Other human error = 83
Weather = 596
Mechanical problem = 374
Sabotage = 114
Cummlative sum = (347 + 83 + 596 + 374 + 114) = 1487
Relative frequency :
Pilot error = 347 / 1487 = 0.233 = 23.3%
Other human error = 83 / 1514 = 0.055 = 5.6%
Weather = 596 / 1487 = 0.401 = 40.1%
Mechanical problem = 374 / 1487 = 0.233 = 23.3%
Sabotage = 114 / 1487 = 0.077 = 7.7%
Based on the relative frequency estimate, Weather is the most serious threat to aviation safety.

Given
[tex]6x + 3y = 12[/tex]
[tex]4x + y = 14[/tex]

Tell whether (5,-6) is a solution
In (5,-6): x = 5 and y = -6.
Substitute these values in the given equations

An experiment was conducted that recorded the weight of a new bar of soap after each use. The line of best fit for the data collected is
y = -5.6x + 123, where y is the weight of the bar of soap, in grams, and x is the number of times that the bar was used.
Which statement describes the meaning of the y-intercept for the line of best fit equation?
Answers
Answer:
The initial weight of the bar soap is 123g
Step-by-step explanation:
No options but the question can still be solved.
Given
[tex]y = -5.6x + 123[/tex]
Required
What does the y intercept mean
Start by calculating the y intercept (i.e. when x = 0)
The equation becomes
[tex]y = -5.6*0 + 123[/tex]
[tex]y = 0 + 123[/tex]
[tex]y = 123[/tex]
This means that the initial weight of the bar soap is 123g

Answers
3x+20=100
Now you would need to move the constant to the right side and change within it’s sign
3x=100-20
Now you would subtract the numbers so for 100-20 would give you 80
So now you then do 3x=80
But if you want to divide the equation, divide it by both sides by 3
Which would give you x=80/3, x=26.6 or x=26 2/3

Ralph Chase plans to sell a piece of property for $150000. He wants the money to be paid off in two ways a - short-term note at 11% interest and a long-term note at 8% interest. Find the amount of each note if the total annual interest paid is $15200
.
Answers
Answer:
Amount on 11% note = $106,666.67
Amount on 8% note = $43,333.33
Step-by-step explanation:
Let the amount for the short-term note at 11% interest be x.
Thus, the amount for the short-term note at 8% interest will be (150000 - x)
Now we are told that the total interest paid is $15,200.
Thus;
0.11x + 0.08(150000 - x) = 15200
0.11x + 12000 - 0.08x = 15200
Rearranging gives;
0.03x = 15200 - 12000
0.03x = 3200
x = 3200/0.03
x = $106666.67
Thus, amount for 8% note = $150000 - $106666.67 = $43,333.33

Based on the pattern, what are the next two terms?
Answers
Answer:

Step-by-step explanation:
By finding the difference between each term, you can find the pattern. 9-6=3, 12-9=3, 15-12=3, so we know that each term is 3 more than the last.
Therefore, by following the pattern of +3, the next term is 15+3=18 and the one after that is 18+3 = 21

Find the difference 0.2−0.05. Show your reasoning.

make them both decimals with a hundredths place (0.2 is the same as 0.20) when you line up the decimals it will look like
0.20
0.05
then you do subtraction like normal, bring the decimal down and you get 0.15
The difference 0.2−0.05 is equal to 0.15.
To find the difference between 0.2 and 0.05.
The larger number is 0.2.
The smaller number is 0.05.
When you subtract 0.05 from 0.2, you align the decimal points and subtract each digit accordingly:
[tex]0.2 - 0.05[/tex]
[tex]= 0.15[/tex]
So, the difference between 0.2 and 0.05 is 0.15.

4. A rectangular strip of aluminum, 30 cm long and 10 cm wide, is rolled into the form of a cylinder.
Which would have the greater volume, a cylinder 10 cm high with circumference of 30 cîn or a cylinder
30 cm high with circumference of 10 cm?
Answers
Answer:
A cylinder 10 cm high with a circumference of 30 cm would have a greater volume
Step-by-step explanation:
Volume of a Cylinder
Given a cylinder of radius r and height h, the volume is calculated as:
[tex]V=\pi r^2h[/tex]
It's given a rectangular strip of aluminum 30 cm long and 10 cm wide. If we roll it to form a cylinder we can do it in two ways.
Rolling it across its length will make the cylinder have a height of h=10 cm and the circumference of the base equal to 30 cm.
The circumference of a circle of radius r is:
[tex]C=2\pi r[/tex]
Thus the radius is:
[tex]\displaystyle r=\frac{C}{2\pi}[/tex]
[tex]\displaystyle r=\frac{30}{2\pi}=\frac{15}{\pi}[/tex]
Thus the volume of the cylinder is:
[tex]V=\pi ( \frac{15}{\pi})^2*10[/tex]
[tex]V=\pi ( \frac{225}{\pi^2})*10[/tex]
[tex]V= \frac{2250}{\pi}[/tex]
If we rolled the strip across its width, then the height will be h=30 cm and the circumference C=10 cm, thus the radius is:
[tex]\displaystyle r=\frac{10}{2\pi}=\frac{5}{\pi}[/tex]
And the volume is:
[tex]V'=\pi ( \frac{5}{\pi})^2*30[/tex]
[tex]V'=\pi ( \frac{25}{\pi^2})*30[/tex]
[tex]V'= \frac{750}{\pi}[/tex]
Dividing V/V' = 3. The first volume it 3 times as much as the second volume.
A cylinder 10 cm high with a circumference of 30 cm would have a greater volume

The length of the base of an isosceles triangle is x. The length of a leg is 4x - 2. The perimeter of the triangle is 95. Find x.
Answers
Answer:
x = 11
Step-by-step explanation:
sides of triangle measure: 'x', '4x-2' and '4x-2' since isosceles means both legs are equal
perimeter is the sum of all sides, so set up equation:
95 = 4x - 2 + 4x - 2 + x
95 = 8x - 4 + x
95 = 9x - 4
99 = 9x
x = 11

7th Grade
52, 55, 57, 57, 58, 60, 60, 62, 64, 65
On average, 7th grade girls tend to be about (these are your answer options for your answer put one of these numbers and tell me which grade) 6,7,5,8 inches taller than 4th grade girls, and ( Answer choices ) there is more variability in the height of 4th grade girls or there is more variability in the height of 7th grade girls.

Step-by-step explanation:
4th grade
44+48+48+51+52+52+54+54+57+60
found the median which is 52 and 52 but you add them and divide them by 2 to get the median which is 104/2= 52
7th grade
52+55+57+57+58+60+60+62+64+65
median is 60 + 58=118/2= 59
59-52= 7
and
there is more variabilty in the hieght f 7th grade girls. because 4th grade has a lot of modes already while 7th grade has only like two so 7th grade will have more variability.
