So scientific notation is making the number manageable.
scientific notation is
(a number >1 and <10) times 10^x
we count how many places the decimal has to move to make the number >1 and >10.
the answer is 6.
5.74 times 10^6
suppose the people have weights that are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.
Find the probability that if a person is randomly selected, his weight will be greater than 174 pounds?
Assume that weights of people are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.
Mean = 177
standard deviation = 26
We find z-score using given mean and standard deviation
z = 
= 
=-0.11538
Probability (z>-0.11538) = 1 - 0.4562 (use normal distribution table)
= 0.5438
P(weight will be greater than 174 lb) = 0.5438

Answer:
The answer to your question is:
x = -10; y = 8
Step-by-step explanation:
Solve equations by elimination method
2x + 3y = 4 (1)
x + 2y = 6 (2)
Multiply 2 by -2
2x + 3y = 4
-2x - 4y = -12
-y = -8
y = 8
Substitute y in (2)
x + 2(8) = 6
x = 6 - 16
x = -10
Answer:
9 2/5 lb
Step-by-step explanation:
Both melon and berries are "fruits."
The total weight of the fruit used is thus 1 lb + 8 2/5 lb, or 9 2/5 lb.
