The answer too 2 plus 2 is 4 because if you have 2 finger and add 2 more up it will be 4
Answer:
first : x²-10x=39
{-3;13}
second : multiply both sides by 1\4
last is : {-1;5}
Answer: what?
Step-by-step explanation:
we need to find the probability that if an individual passenger is randomly selected, their weight will be greater than 166 lb.
Assume that weights of passengers are normally distributed with a mean of 177 lb and a standard deviation of 41.4 lb.
Mean = 177
standard deviation = 41.4
We find z-score using given mean and standard deviation
z = 
=
= -0.265700
Probability (z>-0.26570) = 1 - 0.3974 (use normal distribution table)
= 0.6026
P(weight will be greater than 166 lb) = 0.6026
1.36 < sqrt(2) < 2.45
1.65 < sqrt(3) < 2.34
1.65 < sqrt(4) < 2.34
1.65 < sqrt(5) < 2.34
1.53 < sqrt(6) < 2.46
feel like several of these are wrong sorry
