Answer:
300
Step-by-step explanation:
you just have to add the numbers. £3321
The "expected value of a ticket" is the probability of being drawn multiplied by the earnings associated to being drawn.
($1 is the price of the ticket which of course can be different).
So in this case probability is 1/2000 and the earnings would be valued $1000 (value of the plasma TV).
The expected value is 1/2000*1000=1000/2000=$0,5
This means you should not buy a $1 ticket to play except if this really brings you LOTS of amusement ;)
Answer:
70*
Step-by-step explanation:
we have a right triangle - r is 90*
based on geometric rules: angle RPQ = 20 40 : 2
90 + 20 = 110
110 + x = 180
triangle have 180*
it means that 180 - 110 =
70 *
last answer D
Mass = 100 g
Volume = 50 cm³
Density :
D = m / V
D = 100 / 50
D = 2 g/cm³
answer A
hope this helps!.
