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.
So you divide 50 by 2 so there are 25 before him
Answer:
The system of equations are
and 
Step-by-step explanation:
Given : There are a total of 64 students in a drama club and a yearbook club. The drama club has 10 more students than the yearbook club.
To find : Write a system of linear equations that represents the situation.
Solution :
Let x represent the number of students in the drama club
and y represent the number of students in the yearbook club.
There are a total of 64 students in a drama club and a yearbook club.
i.e.
....(1)
The drama club has 10 more students than the yearbook club.
i.e.
....(2)
Substitute the value of (2) in (1),




Substitute in (2),


Therefore, the system of equations are
and 
Answer:
They are a and b.
Step-by-step explanation:
We have got logarithms to the base 10 here.
We know that log 10^3 = 3 log 10 ( by the law of logarithms).
Also log 10 = 1 ( by definition) so log 10^3 = 3 log 10 = 3.
