Evaluate the expression when x=10, y=−2, and z=−5. −x2+6zy=

x = 10

y = -2

z = -5

-x2 + 6zy = ???

Plug it in:

-(10)(2) + 6(-5)(-2) = ???

-10 x 2 + 6 x 10= ???

-20 + 60 = 40

Therefore, plugging the values in would make it equal 40.

i can answer this question sweetie!

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
