Answer:
Tables are essentially the source for all the charts. They are best used for comparison, composition, or relationship analysis when there are only few variables and data points. It would not make much sense to create a chart if the data can be easily interpreted from the table.
The tables help us to compare the values of those two sets of the data that have been presented in different ways.
Answer:
1/2
Step-by-step explanation:
There are a total of 25 students. 3 don't study art or biology. 10 study only biology. 6 study both art and biology. This means the remaining students only study art.
1. Calculate the number of students taking art
only art: 25 - 3 - 6 - 10 = 6
number of students taking art and biology: 6
total number of students taking art: 12
2. Calculate the probability
Out of the 12 total students taking art, 6 are in art and biology.
6/12 = 1/2
Answer:
A: 1/2 divided by 1 1/2 is 3. 1/2 divided by 1 is 2. 1/2 divided by 2 1/2 5. Multiply those numbers and you get 15 which is how many can fit. B: Idk how to answer part B but you can have part A.
Step-by-step explanation:
Length: 1 1/2. Width: 1. Height: 2 1/2. Volume: how much of ? can fit in a ?. To get the volume you multiply 1 1/2 x 2 1/2 x 1. Make the mixed numbers into improper fractions: 3/2, 5/2, 2/2. Now multiply the numerators: 5 x 3 = 15x 2 = 30. Now in order to finish it you put 2 as the denominator. : 30/2 which as a whole number is 15. 15 cubes can fit.

Step-by-step explanation:
The trick here is the recognize that the diagonal length of the rectangle is the diameter of the circle.
W = width of rectangle = 4
L = length of rectangle = 3
D = diagonal of rectangle
Using pythagorean theorem, we solve for D.
W^2 + L^2 = D^2
(4)^2 + (3)^2 = D^2
16 + 9 = D^2
25 = D^2
5 = D or -5 = D
Since D is a length, D must be positive. Therefore, D=5.
D = diagonal of the rectangle = 5
Since D is also the diameter of the circle AND the diameter of a circle is twice the radius, we have the following equation :
r = radius of circle = 1/2 D = 1/2 (5) = 2.5
C = circumference
C = 2 pi r = 2 pi (2.5) = 5 pi
