Step-by-step explanation:
The ramp is equal to 180
180-6 = 174
Answer:
E) 29.0
Step-by-step explanation:
The value of the sum is obtained from 2 independent experiments: the value of the number of the first box X₁ and the value of the number of the second box X₂.
The expected value of a draw is the average of all its values, so E(X₁) = (1+2+3+4+5+6+7+8+9+10)/10 = 5.5 and E(X₂) = (20+21+22+23+24+25+26+27)/8 = 23.5
Hence, E(X₁+X₂) = E(X₁)+E(X₂) = 5.5+23.5=29
Answer:
The first answer(A) ans the second one(B)
Step-by-step explanation:
A. I did the operations in the parenthesis first and then did the distributive property. I then simplified.
6(2r+(-1))+1
6(2x-1)+1
12x-6+1
12x-5
-4(2+(-3r))+3
-4(2-3r)+3
-8+12r+3
12r-5
Its like a number game in a book
