Answer:
The probability the student studies Art and
Biology is 0.2143.
Step-by-step explanation:
Denote the events as follows:
A = a students studies Art
B= a students studies Biology
The information provided is:
N = 42
n (An B) = 9
n (A' n B) = 10
n (A' n B') =7
Then the number of students who study Art
but not Biology is:
n(An B') = N -n (An B) -n (A' nB) - n (A'n B')
= 42 - 10 - 7 - 9
= 16
The number of students who study Art but
not Biology is 16.
Compute the probability the student studies
Art and Biology as follows:
P(ANB)
n(ANB)
= 0.2143
Thus, the probability the student studies Art
and Biology is 0.2143.
Answer:
Volume of prism is equal to units
Step-by-step explanation:
let the side of the cube be of one unit.
Then, the area of the base is equal to connecting cubes
Assuming a square base of the rectangular prism.
Length of one side of the base of rectangular prism units
Similarly, width of the base of rectangular prism units
The height of the rectangular prism is units
Volume of the prim Length Width Height
Substituting the given values in above equation, we get -
Volume of prism is equal to units
I believe with vertical angles, they are equal to each other.
Therefore,
2y + 5 = 4y
subtract 2y from both sides
5 = 2y
divide 2 from both sides
y = 5/2
