According to a study of 3226 newborn babies in the UK (O' Cathain et al 2002) , birth weight follows a normal distribution with a mean of 3.39 kg, and a standard deviation of 0.55 kg. Find the z-score for a birth weight of 2.78 kg. Find the z-score for a birth weight of 3.82 kg. Find the probability a randomly selected newborn will weigh less than 2.78 kg. Find the probability a randomly selected newborn will weigh more than 3.82 kg. Find the probability a randomly selected newborn will weigh between 2.78 kg and 3.82 kg. Find the probability a randomly selected newborn will weigh less than 2.78 kg or more than 3.82 kg.

sorry, i can't understand your question. will later if you describe more clearly!

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

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
