Answer:
Probability that the cost will be less than $500 is 0.95994 .
Step-by-step explanation:
We are given that Money magazine reported that a visit to a hospital emergency room for something as simple as a sore throat has a mean cost of $348 with a standard deviation of $87.
Let X = cost of a hospital emergency room visit for this medical service
So, X ~ N()
The standard normal z score distribution is given by;
Z = ~ N(0,1)
(a) Probability that the cost will be less than $500 = P(X < $500)
P(X < 500) = P( <
) = P(Z < 1.75) = 0.95994 {from z table}
Therefore, the probability that the cost will be less than $500 is 0.95994 .
The constant of proportionality for this relationship is
Step-by-step explanation:
Proportional relationship is the relation between two variables that vary directly with each other
- If x and y are proportion, then y = k x, where k is the constant of proportionality
- If x and y are proportion, then
, where k is the constant of proportionality
∵ The equation is 3 y = 5 x
∵ x and y are proportional
- That means y = k x, where k is the constant of proportionality
∴ Put the equation in the form y = k x
- Divide both side by the coefficient of y
∵ The coefficient of y is 3
∴ Divide both sides of the equation by 3
∴ y = x
- The value is constant
∴ k =
∵ k represents the constant of proportionality
∴ The constant of proportionality =
The constant of proportionality for this relationship is
