A spinner is divided into five colored sections that are not of equal size: red, blue, green, yellow, and purple. The spinner is spun several times, and the results are recorded below: Spinner Results
Color Frequency
Red 4
Blue 18
Green 10
Yellow 18
Purple 11
Based on these results, express the probability that the next spin will land on red or blue or yellow as a decimal to the nearest hundredth.

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)

the weight of the object inside the box!

-1   1/6.   you dont subtract the denominators
