A line plot with the lengths of meteors is shown. Two more identical meteor measurements were added so that the total length of all meteors measured is 16 inches. What is the length of each new meteor?
Answer:
The answer is 1 3/8 (D)
Step-by-step explanation:
If you added the amounts of each tick mark (which would be 13 2/8), and then subtracted it by 16, it would be 2 6/8. 2 6/8 divided by two (because we need to find the length of both of the indentical meteors) would be 1 3/8.
Now, to make sure it is 1 3/8: 13 2/8 + 1 3/8 + 1 3/8 = 16.
It is confirmed, 1 3/8 (Answer D) is the correct answer.
(Also, I took this test and got it correct :D)

irrational numbers are closed under subtraction true/false
Answer:
False
Step-by-step explanation:
a+(-a)=a-a = 0 which means irrational numbers are not closed under addition or subtraction.
False. Irrational numbers are not closed under subtraction.
Given data:
Closure under subtraction means that if you subtract two irrational numbers, the result will always be another irrational number.
However, this is not true for irrational numbers.
For example, consider the irrational numbers √2 and √2 + √2. Both of these numbers are irrational. However, when we subtract √2 from √2 + √2, we get:
(√2 + √2) - √2 = √2
The result, √2, is still an irrational number. But if we subtract two irrational numbers like √2 from √2, we get:
√2 - √2 = 0
The result, 0, is a rational number, not an irrational number.

Answer:
8/5
Step-by-step explanation:
(-1, 4) (4, -4)
-4-4 over 4-(-1)
That is -8/-5.
-8/-5 is simplified to 8/5
Answer:
1.6

to find the slope, find two points on the line in the graph.
i'll be using (-1, 4) and (4, -4).
substitute the points into the rise over run equation.
[tex]\frac{rise}{run} = \frac{y1-y2}{x1-x2} =\frac{-4-4}{-1-4}[/tex]

songs. What percentage of
the songs were sung by
Mariah Carey?
Answer:
20% were MC
Step-by-step explanation:
Divide number of Mariah Carey songs by total songs.
Total songs = 16 + 4 = 20
4/20 = 0.2
Multiply by 100 to get percent:
0.2 x 100 = 20%

Answer:
21.5≤μ≤25.2
Step-by-step explanation:
The formula for calculating confidence interval is expressed as;
CI = xbar±(z*s/√n)
xbar is the mean = 23.7
s is the standard deviation= 16.3
n is the sample size = 438
z is the z score at 95% confidence level
z = 1.96
Substitute into the formula
CI = 23.7±(1.96×16.3/√438)
CI = 23.7±(1.96×16.3/20.93)
CI = 23.7±(1.96×0.77788)
CI = 23.7±1.5264
CI = (23.7-1.5264, 23.7+1.5264)
CI = (21.4736, 25.2264)
The confidence interval to the nearest tenth is 21.5≤μ≤25.2

the volume of a cylinder is 8,478 cubic inches, and the radius is 15 inches. Which measurement is closest to the height of this cylinder in inches?
Answer:
The height of the cylinder 'h' = 12 inches
Step-by-step explanation:
Explanation:-
Given Volume of the cylinder = 8,478 cubic inches
Radius of the cylinder = 15 inches
Volume of the cylinder is determined by
[tex]V = \pi r^{2} h[/tex]
8,478 = 3.14 × (15)² h
[tex]h = \frac{8478}{3.14 X 225} = 12 inches[/tex]
The height of the cylinder 'h' = 12 inches

Write the equation of the line in slope-intercept form.
Answer: y=-3/4x
Step-by-step explanation:
The slope intercept form is when you use the equation y=mx+b (m is the slope and b is the y-intercept). First, let's find the y intercept. The y intercept is what y would be if x is 0. here, you can see that this particular line passes through the origin. So, the y-intercept is zero because when x passes through zero, y is also zero. Next, let's find the slope. The formula for slope is change in y/change in x. Let's randomly choose 2 points off this line. To make this a thousand times easier for us, let's choose the points (-4, 3) and (4, -3). Now, to find the change in y, let's find the difference between the 2 y coordinates we have chosen. To do this we just need to do -3-3, which gives us -6. Now let's find the change in x. To do this we will do the same thing we did to find the change in y but this time we'll use the x coordinates. We will do 4-(-4), which simplifies to 8. Now, we're almost done. Just divide the change in y by the change in x. You will get -6/8. This can be simplified to -3/4. So now we know our slope is -3/4 and our y-intercept is 0. Let's insert them into the equation. y=-3/4x+0. We know that we can just get rid of that 0 because 0 literally means nothing. So our final answer is y=-3/4x. Hope this helps!
In recent years, Japan's population has been declining at a rate of 0.1% per year. If you were to write an exponential equation representing the situation, what would the decay factor be?
A- .999
B- 0.99
C- .91
D- 1.001
the decay factor for the given decay rate is 0.999
Given :
In recent years, Japan's population has been declining at a rate of 0.1% per year.
we need to find the decay factor for the given exponential rate.
The rate of decay is 0.1%. To remove percentage we divide by 100
so , [tex]\frac{0.1}{100}=0.001[/tex]
The decay rate is 0.001
To find out decay factor , we subtract decay rate from 1
decay factor is 1- decay rate
Decay factor is 1-0.001=0.999
So the decay factor for the given decay rate is 0.999
