Answer:
0.064
Step-by-step explanation:
Step one;
given

Both Art and Biology= 7
Biology but not Art=10
Neither subject= 7
The sample space= 33
Required
the probability of student studying Art and Biology
P(Art and Biology)= 7/33*10/33
=70/1089
=0.064
Answer:
x=5, y=-3, x=-4, y=9
Step-by-step explanation:
1. x=5, is a vertical line cutting the x axis at 5
2. y=-3 is a horizontal line cutting the y axis at -3
3. x= -4, is a vertical line cutting the x-axis at -4
4. y=9, is a horisontal line cutting the y-axis at 9
The answer is what the other guy says
3x + 4 (27 - x ) = 89
3x +108 - 4x =89
x= 19(3 credits courses)
y = 89 -19 = 70
y = 70 (4 credit courses)
I hope this helps!
