Menjawab:
14
Penjelasan:
Dengan 28 pekerja, pekerjaan akan selesai dalam 24 hari
Jika pekerjaan akan selesai dalam 16 hari, jumlah pekerja yang dibutuhkan = x
Asumsikan semua pekerja bekerja pada tingkat yang sama:
Tarif per pekerja:
28 pekerja = 24 hari
1 pekerja = 28 * 24
1 pekerja = 672 hari
Untuk menyelesaikan pekerjaan dalam 16 hari:
672 hari / 16 hari
= 42 pekerja
Pekerja tambahan dibutuhkan:
42 pekerja - 28 pekerja
= 14 pekerja
Oleh karena itu, dibutuhkan 14 pekerja tambahan
Answer:
Option D
Neither gene is significantly different
Explanation:
Tan Spore gene
Cross-over
Observed=189
Expected=177
Observed-Expected=189-177=12
Standard deviation,
Non-cross-over
Cross-over
Observed=139
Expected=151
Observed-Expected=139-151=-12
Standard deviation,
Chi-square value=0.813559+0.953642=1.767202
Rounding off to three decimal places, chi-square value is 1.767
Gray Spore Gene
Cross-over
Observed=204
Expected=216
Observed-Expected=204-216=12
Standard deviation,
Non-cross-over
Cross-over
Observed=124
Expected=112
Observed-Expected=124-112=12
Standard deviation,
Chi-square value=0.666667+1.285714=1.952381
Rounding off to three decimal places, chi-square value is 1.952
Degree of freedom=n-1 where n is sample size, the sample size here are 2 hence degree of freedom is 2-1=1
From chi-square table, when degree of freedom is 1, chi-square value is 3.841
Since for both genes, the chi-square values are less than 3.841 then we should accept that data since it’s not significantly different
Hi there!
Since the passage said that older fossils are most likely underneath newer ones, we can conclude that both fossils were buried at similar depths of ground in similar places.
Hope this helps!
