If the square root of n is approximately equal to 4.2, then n is between . 4 and 5
16 and 25
8 and 9
2 and 3

16 and 25

Step-by-step explanation:

Given that the square root of n = 4.2, let's find an expression for this, then find the possible value of n.

Thus:

Solve for n. Square both sides.

Therefore, if the sqrae root of n was approximately equal to 4.2, then we can conclude that n is between 16 and 25.

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%
