At the beginning of an experiment, a scientist has 348 grams of radioactive goo. After 90 minutes, her sample has decayed to 5.4375 grams.
What is the half-life of the goo in minutes? 22.8
Find a formula for G(t), the amount of goo remaining at time t. G(t) =
348e-031183t
How many grams of goo will remain after 5 minutes?

answer: 1, 3 and 5 are correct

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
