Answer:
Where is the graph?
Step-by-step explanation:
Answer:
y = 5/2x - 5
Step-by-step explanation:
y-int = -5
slope = 5/2
rise/run
alright my friend i've gotta go but i think you can solve these on your own.
just use the number that's on the Y vertical line to find y-int
and then use 2 points and count up to find the rise and then count across to fine thet run.
use the formula y=mx+b
good luck my friend <3
False
Because if you plot a graph to both the equation as i have attached the image.. you can see there can be multiple solution to the above system of inequalities.
Step-by-step answer:
Given:
mean, mu = 200 m
standard deviation, sigma = 30 m
sample size, N = 5
Maximum deviation for no damage, D = 100 m
Solution:
Z-score for maximum deviation
= (D-mu)/sigma
= (100-200)/30
= -10/3
From normal distribution tables, the probability of right tail with
Z= - 10/3
is 0.9995709, which represents the probability that the parachute will open at 100m or more.
Thus, by the multiplication rule, the probability that all five parachutes will ALL open at 100m or more is the product of the individual probabilities, i.e.
P(all five safe) = 0.9995709^5 = 0.9978565
So there is an approximately 1-0.9978565 = 0.214% probability that at least one of the five parachutes will open below 100m
