PLZ HELP NOOOOW!!
1 answer:
Hey there! The answer is 1 1/8 mile.
To find the amount of miles Sarah ran, we need to multipy the length of the track by the times she run that distance.
Rembember: multiplying a fraction means you have to multiply the <span>numerator by the numerator (of the other fraction) and the denominator by the denominator (of the other fraction)
</span>The answer is 1 1/8 mile.

The probability that the reaction time for this density function is at most 2.5 seconds is equal to 0.9.
<h3>What is a density function?</h3>A density function can be defined as a type of function which is used to represent the density of a continuous random variable that lies within a specific range.
<h3>How to calculate the probability that reaction time is at most 2.5 seconds?</h3>P(X ≤ 2.5) = Fx(2.5)
Fx(2.5) = 3/2 - 3/2(2.5)
Fx(2.5) = 3/2 - 3/5
Fx(2.5) = 0.9.
