Answer.
It is Important to open the compass more than half the length so that the arcs made would meet.
Explanation.
When you want to construct a perpendicular line to a line segment, say line AB, the follow steps are taken;
1) Open your compass to a radius greater than half the line AB.
2) With A as your center make an arc on top and below line AB.
3) Using the same radius and with B as our center, make other arcs on top and below line AB to meet the first arcs on both sides of the line.
4) Join the two intersection of the two arcs to cut line AB at M.
In so doing the line AB is said to be bisected perpendicularly. If the compass was opened less than half line AB, then the arcs could not have meet.
C = 45 + 3.75m....the domain in this equation is gonna be ur m values...the number of magazines ordered....so the domain will be all whole numbers...and whole numbers are all positive numbers including 0...no fractions or decimals
5/5 will be a whole, when it comes to 5ths, since she spent 2/5 of her money, 5/5 - 2/5, she has left 3/5 of the whole then.
then she spent 4/9 of her 3/5 leftover, how much is 4/9 of 3/5? well, is just their product,
Answer:
-50 cents
Step-by-step explanation:
The "Winnings" random variable has values -1 and 499
The associated probabilities are P(-1)= 999/1000; P(499)=1/1000
-----------------------------
Expected Value = -1(999/1000) + 499(1/1000) = -500/1000 = -50 cents
