What is the mean for the following set of data, to the nearest whole number 5,9,15,18,and 22

14

Step-by-step explanation:

Mean= add all the numbers up in the set of data and divide by the amount of numbers you added

so 5 +9 + 15 + 18 +22 = 69

69 divided by 5=13.8  round to the nearest whole number =14

answer: 12

step-by-step explanation:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
