The salaries of the employees at four companies are summarized below. answer the questions about them.

Range = 24

Step-by-step explanation:

Record of percentage

59, 61, 83, 67, 81, 80, 81

We need to find the range

To find the range , we order the numbers from smallest to largest.

Then Subtract the smallest number from largest number.

When we arrange the numbers it becomes

59, 61, 67, 80, 81, 81, 83

Smallest number is 59 and largest number is 83

Range = 83 - 59 =24

42

step-by-step explanation:

256/6=42

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
