Answer:
She can do better in math.
Step-by-step explanation:
Any point (x) from a normal distribution can be converted to the standard normal distribution (z) with the formula z=

for french x = 81 and mean 72 ,standard deviation = 9
for french the value of Z = 
= 
= ±1
For math x =86 and mean=68 ,standard deviation = 12
for math the value of z
=±1.5
Since value of Z is more in subject math as compare to that of French
so she did better in Mathematics
Answer:
2 movements
Step-by-step explanation:
In this case what we will do is name the white chips "W" and the black ones "B". If there are 9 tiles and 4 are in black then the rest, that is 5, in white, like this:
B-B-B-B-W-W-W-W-W
First movement, in turn we can flip 3 tiles, in this case we flip two blacks and one white, it would look like this:
W-W-B-B-B-W-W-W-W
The second movement is to turn the 3 black ones and thus they would all be blank
W-W-W-W-W-W-W-W-W
In other words, the smallest number of movements is 2.
