2(x^2y+7)(y^3-5)
x^2y+7 Is a factor
Answer:
The price of the watch is 280$
Step-by-step explanation:
We know that the original price is 400 dollers, and its on sale for 30%.
So we do 30% of 400 = 120$
finally we do, 400$ - 120$ = 280$
so the final price of the watch is 280$

Answer:
0.4 , 0.1
Step-by-step explanation:
Let number of boys be = b , number of girls = b + 4 . As total students = 20 b + b + 4 = 20 → 2b + 4 = 20 → 2b = 20 - 4 = 16 → b = 16 / 2 = 8 (boys) , so girls = 12
Prob (a random first child is a boy) = boys / total students = 8 c 1 / 20 c1, or = 8 / 20 = 0.4
Prob ( a 'Tina' out of two Tina is the last) = 2 c 1 / 20 c 1 , or = 2 / 20 = 0.1
