Answer:
Independent
Dependent
Step-by-step explanation:
Two events are independent of each other when you can mulitply them and get their intersect
we can can see that
9/20*7/10= 63/200 so these events are independent
For number 2
7/10*7/10≠ 21/40 so these events are dependent
Answer:
94 cm^2
Step-by-step explanation:
The surface area of a rectangular prism can be found using:
A=2(wl+hl+hw)
We know the width is 3, the height is 5, and the length is 4. We can substitute 3 in for w, 5 in for h, and 4 in for l.
A=2((3*4)+(5*4)+(5*3))
Multiply 3 and 4
A=2(12+(5*4)+(5*3))
Multiply 5 and 4
A=2(12+20+(5*3))
Multiply 5 and 3
A=2(12+20+15)
Add 12 and 20 and 15
A=2(47)
Multiply 2 and 47
A=94
So, the the surface area is 94 cm^2
Answer:
6
Step-by-step explanation:
I think its 6 times greater because the length was tripled and the width was doubled thus : 3 * 2 = 6
