Answer:
38.89% probability that a student that is taking Physics is also taking Statistics
Step-by-step explanation:
Conditional probability formula:
Two events, A and B.
In which
P(B|A) is the probability of B happening, given that A has happened.
is the probability of these two events happening.
P(A) is the probability of A happening.
In this problem, we have that:
A: physics
B: statistics.
90% of the students take Physics
This means that 
35% of the students take both Physics and Statistics.
This means that 
So
38.89% probability that a student that is taking Physics is also taking Statistics
If the 11 is positive, positive
if the 11 in hegative (p*n=n) so a negative
Find gradient by changing form of equation: y = 2/3x + 4. Gradient is 2/3.
Find y intercept of other line by substituting the coordinates: -8/3
Use information to write out equation of line: y= 2/3x - 8/3
Convert to standard form: -2x + 3y = 8.
Hope this helps :)
Answer:
Step-by-step explanation:
When mutliplying numbers with exponents by an exponent, you simply add the exponents. So the exponent would be 6, because 2+4=6
3x times 2x+3xy-2y times 2x-2y times y
6xsquared+3xy-4xy-2ysquared
6xsquared-xy-2ysquared
