Making handcrafted pottery usually takes two major steps:wheel throwing and firing. The time of wheel throwing and thetime of firing are normally distributed random variables with meansof 40 min and 60 min and standard deviations of 2 min. and 3 min, respectively.
(a) What is the probability that a piece of pottery will befinished within 95 minutes?
(b) What is the probability that it will take longer than 110minutes?
answer: i'm not sure
step-by-step explanation:
are you an artist's daughter? cuz dang you a fine piece of art, girl.
the system of inequity is
step-by-step explanation:
from the given graph it is noticed that we have two related lines. one is solid and another is dashed.
if a line passing through two points, then the equation of line is
the solid line passing through the points (0,4) and (4,0).
the related equation of solid line is .
similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).
the related equation of dashed line is
from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.
check the related equations by the point (0,1).
this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is
similarly, check the second related equation.
it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
