The expected value should be a 1/3 change because you have three coins each , then 1/6 altogether change or randomization the most realistic highest expected value is you paying them 2$
Step-by-step explanation:
a/q both the traingles are similar/congruent so,
theri angles also have equal value
angle Q = angle A
so,
apply angle sum property of triangle in ∆PQR
so according to it
Angle
P + Q + R = 180
→ 45° + 15° + Q = 180
→ 60° + Q = 180
→ Q = 180 - 60 = 60°
→ angle Q = 60°
therefore, angle A = 60°
Angle R = angle B
so,
angle B = 15°
as, angle P = angle C
so,
angle C = 45°

Answer:

Step-by-step explanation:
From the question we are told that
5% solution of dextrose sugar in water
20% solution of dextrose in
100 milliliters of distilled water water
Generally in mathematically solving we call A the amount of D20W added
Since 20% of dextrose is needed

Total quantity after addition (100+x)
for DW5% total solution is


Mathematically




Therefore the required quantity 
Answer:
b $.05
Step-by-step explanation:
5 lbs is .80 and 8 lb is .75 so a 5 cent difference per lb
