Answer:
0.2
Step-by-step explanation:
Given the data :
Day : Mon Tue Wed Thu Fri Sat Sun
# of sick days 22 11 16 17 21 28 25
The expected count of sick days taken on Saturday is obtained thus :
Expected count = (row total * column total) / overall total
Here, the table is just one way :
Hence, we use :
Observed value / total days
Hence,
Expected count on Saturday = sick days on Saturday / total sick days
Expected count on Saturday = 28 / (22+11+16+17+21+28+25)
Expected count on Saturday = 28 / 140
= 0.2
Answer:
You would expect to get 50 heads
Step-by-step explanation:
Each time you flip a coin you will either get heads or tails. This means that you have a 1/2 probability of getting heads. If you use this then you need to multiply 1/2 and 100 to get the expected amount of heads. Multiplying by a half is just dividing by 2. Therefore, the answer is 100/2 = 50. The answer is 50 heads
it equals 25 cause its bending
Answer:
Step-by-step explanation:
21. The exponents cannot be added in the product having bases 12 and 11 because the bases are different. They can only be added if the bases are same.
22. a) (3¹)⁵
b) ⁵√(3²⁵)
c) (3⁵)³ ÷ (3⁵)²
23. The distance from the Earth to moon is 22⁴ miles
The distance from the Earth to Neptune is 22⁷ miles
The distance from the Earth to Neptune is greater by = 22⁷/22⁴ = 22⁷⁻⁴= 22³miles.
It is greater by three times
24. 8³. 8⁻⁵= 8³⁻⁵= 8⁻²= 1/8²= 1/64
1/64 ∠ 1
The student is not correct as 1/64 is less than 1.
