Answer:
x^2 + 2x +1 = 2x + 2
Step-by-step explanation:
(x+1) = 2
multiplying both sides by x +1
(x +1) (x+1) = 2 (x+1)
x^2 + 2x +1 = 2x + 2
Answer:
Option b) 6-10 lbs
Step-by-step explanation:
Given that X, the weight of toy American Eskimo dog has mean of 8 pounds with a standard deviation of 1 pound
For 95% of the dogs according to normal distribution would lie between 2 std deviations on either side of the mean.
i.e. lower bound= Mean- 2 std deviation = 8-2 =6
Upper bound = Mean +2 std dev = 8+2 =10
Hence range of weights would be
6-10 lbs
Option b is the answer
2.8x10^-5 ; 2.8x10^-3 ; 2.8 ; 2.8x10^2 ; 2.8x10^4
Supplementary, complementary, neither
You wanna cross out numbers if they can both divide by the same number. then multiply the numbers in the same row together
