Auntie Barbie's Yummies markets a two-pound box of assorted treats. Because of imperfections in their equipment, the actual weight of the box of treats has a continuous uniform distribution ranging from 31.8 to 32.6 ounces. What is the probability that a box weighs exactly 31 ounces?

the probability that a box weighs exactly 31 ounces is 0

Step-by-step explanation:

since the box has a continuous distribution (therefore there are infinite real numbers between 31.8 and 32.6 ounces) , the probability of a exact value out of a infinite quantity is 0  . Mathematically , since the probability for a random variable X to be between values of 'a' and 'b' for a continuous probability density function f(x) is

P(a≤X≤b)=∫ₐᵇ f(x) dx  

for b=a, then

P(X=a)= ∫ₐᵃ f(x) dx = 0

Nevertheless , since the value of 31 is outside the range of 31.8 and 32.6 ounces, the probability of a value outside the continuous distribution is also 0

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
