Answer:

20% chance.

Step-by-step explanation:

If you do not know the formula, here is a quick intuitive method.

Construct the sample space in a square with 4 divisions

split one side into 1/2 and 1/2 and the other side into

.4 and .6

You can easily see that the day that it will rain on both days is .2 (1/2*.4)

or 20%

Order the decimals from least to greatest 3.4897, 3.3487, 1.5467, 3.348
Anna71 [15]

Answer:

1.5467, 3.348, 3.3487, 3.4897

Step-by-step explanation:

Remember to compare each one number at a time!

For the first number, only one number is 1 while the others are 3 making it the lowest.

Then when comparing 3.348 and 3.3487, it can be implied that there is a 0 at the end of 3.348 because it makes the numbers have the same # of decimal places without changing the value of the number (3.3480). That number is less than 7.

Finally, 3.4897 has a 4 in the tenths place instead of a 3 making it the highest number.

Hope this helps!

3(2x-5)= 21<br> solve it 2 different ways <br> plzz hurry i need help
docker41 [41]

Answer:

x = 6

Step-by-step explanation:

3 (2x - 5) = 21

=> 6x - 15 = 21

=> 6x = 21 + 15

=> 6x = 36

=> x = 36 / 6

=> x = 6

OR

3 (2x - 5) = 21

=> 2x - 5 = 21 / 3

=> 2x - 5 = 7

=> 2x = 7 + 5

=> 2x = 12

=> x = 12 / 2

=> x = 6

Hope it helps :)
