Answer:
Your right?
Step-by-step explanation:
its the only answer that actually qualifies. Although any number above 20 would work I guess. there are no requirements.
Answer:
I guess 21, its only one that makes sense to me.
Step-by-step explanation:
21 is over 20, and you can sell no less than 20, all other answers are below 20, so the only one that makes sense is 21.

A fair number cube with numbers 1-6 was rolled 500 times. The number 4 was landed on 62 times. If the die was rolled 3,000 times, how many times would it be expected to land on 4, based on the experiment?
a 10
b 372
c 62
d 500
Step-by-step explanation:
62/500 is the proportion of rolling 4 to all the rolls, so we just need to expand the fraction so that the denominator is equal to 3000
3000÷500=6
6*62=372 B

i would say A. a convenience sample that is not representative of all first-year college students. there are more than 20 first-year college students in the world so obviously only talking to 20 of them won't be representative of /everyone/
and the convenience is that she only handed them out to people in the library; where she spends most of her time, therefore making it more convenient for her.

A cylindrical tube of length 27.75 cm and radius 2.00 cm is filled with argon gas. The empty tube weighs 188.25 g. The tube filled with argon weighs 188.87 g. Calculate the density.
formula =
[tex]V = \pi r^2h[/tex]
Step-by-step explanation:
V= π(2)^2(27.75)
= 348.72cm^3
D=188.87g/348.72cm^3
= 0.54g/cm^3

Gina has borrowed 100 songs from her friend. She plans to download an equal number of songs on her music player each week for 5 weeks. The graph shows the number of songs left to download, y, for a certain number of weeks, x:
Part A: What is the rate of change and initial value of the function represented by the graph, and what do they represent in this scenario? Show your work to find the rate of change and initial value. (6 points)
Answer:
A. initial value = 100 (total amount of songs to download)
rate of change = -20 songs/week
B. y = -20x + 100
Step-by-step explanation:
A. The initial value of the function represented by the graph is its y-intercept point, that is, the value at which the function intercepts y-axis. In this case, this value is 100 songs. It represents the number of songs left before start to download them.
The rate of change is computed at follows:
[f(x2) - f(x1)]/(x2 - x1)
where (x1, f(x1)) and (x2, f(x2)) are two points on the line. Using (0, 100) and (1, 80), we get:
rate of change (80 - 100)/(1 - 0) = -20
This means that each week there are 20 songs less than the previous week.
B. In general terms, the slope-intercept form is:
y = mx + b
where m is the slope (which coincides with the rate of change), and b is the y-intercept (or initial value). Replacing with the results of part A:
y = -20x + 100
Step-by-step explanation:
Answer:
y = -20x + 100
Step-by-step explanation:
As per your requirement For Part B, the solution is
The equation in slope-intercept form to model the relations is below:-
To reach 2 points on the graph the line passes through
lets use p1(0, 100), p2(1, 80)
now we will compute the slope:
= -20
and now use line equation in form point-slope:
y - y1 = m(x - x1)
y - 100 = -20(x - 0)
y = -20x + 100

Refraction:

Most microscopes take advantage of ....
Diffraction:
X - ray crystallography ....
The spreading out of waves...
Explains why anyone in the classroom can hear that loud teacher...
Step-by-step explanation:
Let us first differentiate reflection, refraction, and diffraction.
Reflection occurs when the waves bounce off the medium or the boundary that is in the way of the wave. Some part of the wave would bounce off, and the others would go through the medium through a process called transmission.
When light for example hits a smooth surface at a certain angle, the light would bounce off, creating an equal going the other way.
Best example of this behavior of light would be the mirror.
Refraction on the other hand, bends the waves as they go through one medium to another medium, or change their direction. The amount or degree of the bend would depend on the medium they go through. If the mediums are different, it would substantially change the wave's path. The reason for this is because the medium changes the speed of the waves that go through them, depending on the material they are made up of.
A classic example of this would be the straw in a glass of water.
Diffraction occurs when the waves go through an opening of the medium or barrier. If the opening is smaller than the wave that passes through it, it would spread out wider, coming out of the opening, but if it is bigger, then the spread would decrease.
In x-ray crystallography, they use this by letting x-rays pass through the spaces in between the crystals.

Answer:
14 deliveries
Step-by-step explanation:
First we have to find out how much he makes in a day aside from what he makes a day aside from his deliveries, so 9 x 8 = 72. Then we take 155 - 72 = 83. Then since he wants to make more than 155, we'll add one to 83, then take that divided by 6. 84/6=14. So he'd have to make at least 14 deliveries to make $156 in a day.
Answer:
D. 14
Step-by-step explanation:
Write the expression (explanation)
9 per hour= 9xh= 9h
and= addition
6 each delivery= 6xd=6d
more than= >
Final expression you need to solve
9h+6d>155
how many hours?: 8 hours
9(8)+6d>155
solve for d
72+6d>155
6d>83
d>~13.83
He cannot make less than 13.83, so you would round it up to 14.
