If log x = 3 and log y = -2, then log x^2y =

7

Step-by-step explanation:

Plug in the given numbers to the x and y values.

It should look like this: 3² - 2

Now you just need to solve it.

3 to the power of 2 is 9 and 9 - 2 is 7. So you answer is 7.

( 3² - 2 --> 9 - 2 --> 7 )

Also when doing this remember PEMDAS!!

P = ( )

E = exponents

M/D = Multiply/Divide

A/S = Add/Subtract

70

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
