Step-by-step explanation:
To convert 0.007407 into scientific notation, follow these steps:
Move the decimal 3 times to right in the number so that the resulting number, m = 7.407, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -3
Write in the scientific notation form, m × 10n
= 7.407 × 10-3

Answer:
12 weeks
Step-by-step explanation:
If John is aiming to save $100, with $6 a week and he has already saved $28. The leftover amount to be saved is $100 - $28 = $72
In one week → $6
2 weeks → $12
3 weeks → $18
and so on..

John will need 12 more weeks to save a total of $100.

Answer:</em></h3>
<em>mean = 4</em>
<em>Median = 3</em>
<em>Mode = 1</em>
Step-by-step explanation:
first let’s arrange the numbers from least to highest:
1 , 1 , 1 , 2 , 3 , 3 , 5 , 5 , 15
=====================
The median is the number that’s comes in the middle of the data set ⇒ median = 3 ( the fifth number in the data set)
1 , 1 , 1 , 2 , <u>3</u>, 3 , 5 , 5 , 15
________________________
The mode is the number that repeats the most ⇒ mode = 1 (repeated 3 times)
____________________________________

It is x=8 because 13+7=20 and 28-20 would be 8 and that's the missing number.
