Find the mode in 18 7 4 19 3 18 19 12
scoundrel [369]
Hello there,

We need to remember that Mode means: the number that appears more than others.

18 will be your correct answer because the number 18 appears 2 times. And there is no other number that appears 2 times except 18.

18 is your answer.

Someone please answer this correctly!!
Luda [366]

Answer:

1.98 × 10^10

Step-by-step explanation:

First solve for how many text messages were sent out per one month:

22,000,000 × 900

19,800,000,000

Convert into scientific notation:

1.98 × 10^10

In scientific notation, there can only be one number before the decimal. The rest of the numbers must be after the decimal; hence, why I put the numbers 9 and 8 after the decimal. If the rest of the numbers are zeros, you do not have to add them after the decimal. Instead, starting from right to left, count the number places until you reach your decimal. The number you have counted will be your exponent. I counted nine 0's, one 8, and one 9 which made this exponent 10 as there were 10 decimal placements.
