Julia has a jar that contains a mixture of dimes and pennies. she reaches into the jar without looking and selected a coin. she repeats this process 14 times, which result 8 dimes and 6 pennies. based on these results, about how many pennies can she expect if she randomly select a total of 70 coin a.24 b.30 c.40 d.53

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
