Answer:
if a·b=0, then either a=0 or b=0, or both
Step-by-step explanation:
just answered it on apex :)
Probabilities are used to determine the chances of selecting a kind of donut from the box.
The probability that Warren eats a chocolate donut, and then a custard filled donut is 0.068
The given parameters are:



The total number of donuts in the box is:


The probability of eating a chocolate donut, and then a custard filled donut is calculated using:

So, we have:

Simplify

Multiply

Divide

Hence, the probability that Warren eats a chocolate donut, and then a custard filled donut is approximately 0.068

12 2 +16 2 = D2
D2= 144+256
D2= 400
D2= 400
The answer is true because they both have the 90 degree box and a mark in the line indicating they are the same length.
Answer:
slope of line pass throught jk is 0.5 slope
since line perpendicular to jk then x × 0.5= -1 so slope of line perpendicular is -2
then eq of line is y= -2x -15
