Each day it decrease $2. So just multiply $2 x 4 days. It changed a total of $8.
Answer:
1) No
2) No
3) Yes
4) No
5) Yes
Step-by-step explanation:
All three sides must add with another to be greater than the last side (Not sure if that makes sense ._.)
Let's call Frank's house F, Derek's one D n Evan's E.
F(5,-4)
E(-3,-4)
D(-3,4)
FE=5-(-3)=5+3=8
ED=4-(-4)=4+4=8
We can see the triangle is a half of a square, so FD is 8(√2)≈11.312
11.312+8=19.312
The answer is C.19.31
Answer:
P(at least one wrong) = 1- P(all correct) =1-.25^6=1-1/4096=4095/4096. This assumes that the answers are picked at random. This kind of question is always the complement of an extreme binomial outcome.
