PLEASE SOMEONE TO HELP ME WHAT ARE THE CORRECT ANSWERS AND IM GIVING BRAINLY
GrogVix [38]

Answer:

10 times greater

Step-by-step explanation:

When you write these as numbers, you get:

800,000,000 (8 hundred million place)

80,000,000 (8 ten million place)

Then divide the greater number by the less number:

800,000,000/800,000,00

make this easier by eliminating 0's:

80<u>0,000,000</u>/8<u>0,000,000</u>

80/8

10

10 times greater is your answer

Hope this helps!

Diane has the following data:
Vladimir [108]
To determine the median, we need to set up our numbers from least to greatest, and then place T in later to figure out what T is.
8, 9, 9, 9, 10, 11, 12, 15. Cross out the smallest number with the largest number.
9, 9, 9, 10, 11, 12.
9, 9, 10, 11.
9, 10.
9.5 is our median currently.
Since we need to get a number after 10 to make 10 the median, let's use 12.
8, 9, 9, 9, 10, 11, 12, 12, 15.
9, 9, 9, 10, 11, 12 ,12.
9, 9, 10, 11, 12.
9, 10, 11.
10 is now our median since we inserted 12 into our list.
Your answer is 12.
I hope this helps!
