Let x be the lengths of the steel rods and X ~ N (108.7, 0.6)
To get the probability of less than 109.1 cm, the solution is computed by:
z (109.1) = (X-mean)/standard dev
= 109.1 – 108/ 0.6
= 1.1/0.6
=1.83333, look this up in the z table.
P(x < 109.1) = P(z < 1.8333) = 0.97 or 97%
Answer:
605100
Step-by-step explanation:
= 6.051 × 105
(scientific notation)
= 6.051e5
(scientific e notation)
= 605.1 × 103
(engineering notation)
(thousand; prefix kilo- (k))
= 605100
(real number)
Answer:
(a) = 40%
(b) = 28%
(c) Expected value = $222,500
Standard deviation = $7,216.88
Step-by-step explanation:
This is a normal distribution with a = 210,000 and b =235,000
(a) The probability that he will get at least $225,000 for the house is:

(b)The probability he will get less than $217,000 is:

(c) The expected value (E) and the standard deviation (S) are:

Hey there I see you need help well I am here to do just that your answer would be 1/4 so each of the 3 patties are 1/4th of a pound hopes this helps
