The total time Ali spent hiking and resting is 4 1/2 hours
How to add fractions
- Time spent hiking = 3 3/4hours
- Time spent resting = 3/4 hour
Total time spent hiking and resting = 3 3/4 + 3/4
= 15/4 + 3/4
= (15+3) / 4
= 18/4
= 9/2 hours
= 4 1/2 hours
Therefore, the total time Ali spent hiking and resting is four and one half hours (4 1/2) hours.

Answer:
In cell biology, mitosis (/maɪˈtoʊsɪs/) is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained. Therefore, mitosis is also known as equational division. In general, mitosis is preceded by S phase of interphase (during which DNA replication occurs) and is often followed by telophase and cytokinesis, which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components. The different stages of mitosis altogether define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two daughter cells genetically identical to each other.

Using the appropriate sample size formula, the minimum number of samples required is 267
<u>Using</u><u> </u><u>the</u><u> </u><u>relation</u><u> </u><u>:</u>
- N = [(Z² × pq) / e²]
- e = Error Margin = 0.06² = 0.0036
- p = 0.5
- q = 1 - 0.5 = 0.5
- Zcritical at 95% = 1.96
<u>Substituting the values into the equation</u> :
N = [(1.96² × (0.5 × 0.5)) / 0.0036]
N = (0.9604 / 0.0036)
N = 266.777
N = 267
Hence, the minimum number of samples required is 267
