Australia is 2.97 x 106 square
Arlecino [84]

Answer:1.7

Step-by-step explanation:

First you want to multiply 2.97 by 106

2.97 x 106 = 314.82

Now you want to multiply 1.72 by 107

1.72 x 107 = 184.04

Now you want to divide them

314.82 / 184.04 = 1.71

Now you want to round it to the nearest tenth... if a number is 5 or above you round it up but if it is 4 or below your number stays the same

Since 1 is lower than 5 you keep your number the same

Colin rolls a fair dice and flips a fair coin.
Ilia_Sergeevich [38]

Answer:

8.3%

Step-by-step explanation:

In a simple way, we know that both are independent events, therefore, in the case of the dice it has 6 faces, therefore the probability of 3 coming out is 1/6 and in the case of the coin it only has two options, which means that the probability is 1/2.

Now the final probability is the multiplication of these events, that is:

1/6 * 1/2 = 0.083

Which means that the probability of these two events happening is 8.3%

How do you know when to use the Estimation strategy vs the Guess and Check strategy ?​
Grace [21]
The guessing strategy only works when you don’t u don’t understand a question so I advise you NOT to do it , only when it’s necessary but the Estimation strategy works when you don’t have a any but a answer where theirs decimals or a answer that is close to one another and can be rounded
