Answer:
8
Step-by-step explanation:
You know a cube has 6 sides, so you divide 24 by 6 to get the surface area of 1 side
24/6 = 4
Then to get the side length of the cube, square root 4
[tex]\sqrt{4} = 2[/tex]
To get the volume, multiply the base (4) by the height (2)
4*2 = 8

The dot plots below show the test scores of some mathematics students and some science students: Two dot plots are shown one below the other. The top and the bottom plots have the title Mathematics Students and Science Students respectively. Below the line for each dot plot is written Mark. The markings on each line are from 30 to 50 at intervals of 1. For the top plot there are two dots each for 34 and 40 and 1 dot each for 32, 33, 35, 37, and 39. For the bottom plot there are 2 dots each for 43, 46 and 49 and 1 dot each for 41, 42, and 47. Based on visual inspection of the dot plots, which group of students appears to have the larger average score?
Answer:
Science students
Step-by-step explanation:
MATHEMATICS :
Plot interval = 30 to 50
MEAN :
(34*2) + (40*2) + (32*1) + (33*1) + (35*1) + (37*1) + (39*1) = 324
Sample size, n = (2 + 2 + 1 + 1 + 1 + 1 + 1) = 9
Mean = 324 / 9 = 36
BOTTOM :
SCIENCE :
MEAN : (43*2)+(46*2)+(49*2)+(41*1)+(42*1)+(47*1) =
406
SAMPLE SIZE = (2 + 2 + 2 + 1 +1 +1) = 9
406 / 9 = 45.111

Diane has pulled 2 green marbles and 10 other marbles from a large bag. What is the experimental
probability that the next marble selected from the bag will be green?
The experimental probability that the next marble selected from the bag will be green is 1/6.
What is the experimental probability?Experimental probability is the probability that an event would happen based on a previously carried out experiment.
The experimental probability that the next marble selected from the bag will be green = total number of green marbles / total number of marbles
2 / ( 2 + 10)
= 2/12
= 1/6

if x+2 is a factor of the polynomial: 3x²+kx, then the value is
Answer:
k = 6
Step-by-step explanation:
(x+2) is a factor of 3x²+kx so if we solve (x+2) = 0 that will give us one of the solutions of x for 3x²+kx = 0, and then we can substitute that solution in and find the value of k.
So to find a solution, (x+2) = 0 and therefore x = -2
Now substitute x = -2 into 3x²+kx = 0
so 3(-2)²+k(-2) = 0
12 - 2k = 0
2k = 12
k = 6

Step-by-step explanation:
Volume of a rectangular prism = Length times Width times Height
If width = 3, length = 2 and 1/4 and height = 4 and 1/2
Then volume = [tex]3*2\frac{1}{4} *4\frac{1}{2}[/tex]
[tex]3*2\frac{1}{4} *4\frac{1}{2} =\frac{243}{8}[/tex]
Therefore the volume of the prism is 243/8 or 30.375
Answer:
30 3/8 or 30.375 m^3
Step-by-step explanation:
I'm not sure if they want the decimal or fraction, so I gave both.
1/4 = 0.25
1/2 = 0.5
3 * 2.25 * 4.5 = 30.375 m^3

Actually Welcome to the concept of straight lines.
==> y-y1 = m(x-x1)
==> y = mx+c
these two are the straight line equation, so we get as,
=> 0-0 = m(8-(-7)
==> 0 = m(15)
==> hence, 15m = 0

Mila graphs the point A (5, 0) on a coordinate plane.
Which of the following statements are true?
Select all that apply.
Point A is 5 units to the right of the origin and up 1 unit______________
B. The x-coordinate of point A is 5.
C. The y-coordinate of point A is 5.
D. Point A is on the y-axis.
E. Point A is on the x-axis.
Answer:
answers B and E are true.
Step-by-step explanation:
(5,0) means x=5, y=0
the point of origin is (0,0) with x=0, y=0
therefore, A is wrong. yes, the point is 5 units to the right of the origin, but 0 (no) units up. and not 1.
B is therefore true.
C is therefore wrong.
D is wrong, because the point is to the right of y-axis (the vertical axis) and not on it.
E is true, because we go only to the right of the origin, but neither up or down. so, we stay on the x- axis (horizontal axis).

Does anyone know how to solve this?
Answer:
$ 22.5
Step-by-step explanation:
B(x) = 30.50 - 0.20x
Notice that x defines the number of prints.
For prints = x = 40
B(40) = 30.50 - 0.20(40)
B(40) = 30.50 - 8
B(40) = 22.5
Remaining amount is $22.5
B(x) is defined as at starting you had $30.50 then you kept on spending with a period of 20 cents(= 0.20 dollar). So 30.50 kept on decreasing by 0.20. Each time you spend, you give 0.20.
That's why the function is 30.50 - 0.20x.
Where x is the nunber of times you spend(buying prints)
