Answer:

799

Step-by-step explanation:

Let x = the hundreds digit

Let y = the ones digit

x = y-2

We want to maximize x and y. The both have to be single digit numbers

Rewriting this

x+2 =y

The largest x can be is 7 if y is a single digit

x is 7 and y is 9

We can pick the tens digit. Make it as big as possible to make out number as large as possible

Answer: $\dfrac{1}{3}$

Step-by-step explanation:

Favorable outcomes (sum is a multiple of 3): (1,2) , (1, 5), (1,8), (2,1) , (2,4), (2,7) , (3, 3), (3, 6), (4, 2), (4, 5) , (4, 8), (5,1), (5, 4), (5, 7), (6,3), (6, 6).

Number of favorable outcomes (sum is a multiple of 3): 16

Total outcomes = Total outcomes of 6-sided die x Total outcomes of 8-sided die=6 × 8 = 48

Then , the probability of getting numbers whose sum is a multiple of 3:

$=\dfrac{\text{favorable outcomes}}{\text{total outcomes}}\\\\=\dfrac{16}{48}=\dfrac{1}{3}$

Hence, the required probability = $\dfrac{1}{3}$

Explain how an estimate helps you place the decimal point when multiplying 3.9 × 5.3

4vir4ik [10]

An estimate helps you place the decimal point when multiplying because if you find out how many decimals there are and once you are done doing you estimated multiplication you put two decimal points after that.

Hope I helped some what and didn't make you confused.
