SOMEONE HELPPPPPPPPP PLEEEASSEEEEEE IMMMM STUCCCCKKKKK PLLEASSE ILL GIVE YOU 24 POINTs: On Monday, Jan made withdrawals of $25,

kolezko [41]

Just write down the negative values of each withdrawal and add up those values for the first two.
1. -25 + -45 + -75 = -145
2.-35 + -55 + -65 = -155
As for the third question, the brother took out $10 more than Julie, so he withdrew $165. A possible equation with possible values could be:
3. -15 + -65 + -85 = -165
Keep in mind that there are multiple ways to answer the third question and that's only one of them. Hope this helped!

The reaction time (in seconds) to a certain stimulus is a continuous random variable with pdf f(x) 5 5 3 2 ? 1 x2 1

muminat

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.
