It is B. You divide 10 by 25 and multiply it by 100
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 .
Answer:
option A is correct. this graph is a linear function
Step-by-step explanation:
Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept
