Answer:
I don't think I can remember every skill I was taught through the years but in Kindergarten we used Number Sense so we could understand the meaning of more and less also there's estimation and PEMDAS. I've also learned how to round up so that the solution is at least around those numbers if the skill is to be applied.
hope that helps

Answer:
Step-by-step explanation:
An option to buy a stock is priced at $150. If the stock closes above 30 next Thursday, the option will be worth $1000. If it closes below 20, the option will be worth nothing, and if it closes between 20 and 30, the option will be worth $200. A trader thinks there is a 50% chance that the stock will close in the 20-30 range, a 20% chance that it will close above 30, and a 30% chance that it will fall below 20.
a) Let X represent the price of the option
<h3><u> x P(X=x)
</u></h3>
$1000 20/100 = 0.2
$200 50/100 = 0.5
$0 30/100 = 0.3
b) Expected option price

Therefore expected gain = $300 - $150 = $150
c) The trader should buy the stock. Since there is an positive expected gain($150) in trading that stock option.

Answer:
30 short cakes
Step-by-step explanation:
25ml = 10ml + 10ml +5ml
each 10ml of milk can make us 12 short cakes
we can two 10ml of milk (20ml) which can make us 24 short cakes.
but we have 25 ml of milk so how much does 5ml of milk give us if 10ml of milk gives us 12 short cakes ?
5ml makes us 6 short cakes. 24 short cakes plus 6 short cakes =30 shortcakes.
25ml of milk =10ml(12shortcakes)+ 10ml(12 shortcakes)+5ml(6 shortcakes)
A²+b²=c²
64+b²=196
b²=132
b=11.48912529
