Step-by-step explanation:
2) 8,6,5,3 ,57 7,4,2/8
=92/8
mean =11.5
Arrange the terms in ascending order
2,3, 4, 5, 6, 7, 8, 57
the median of the ascending set= 5.5
3) 72 75 85 82 37 108/ 6
459/6
mean =76.5
Arrange the terms in ascending order
37, 72, 75, 82, 85, 108
the median of the ascending set= 78.5
4) 10 students were asked because there were 10 data values in the list.
5) it should be 55/10 =5.5
so its false
6) Sum first and find the mean number
5+4+3+2+1/5
=3
Answer:
0.000462
Step-by-step explanation:
From the given information:
The cotton count of the piled yarn is the ratio of the simple weight in (g) with the length by the simple length with weight.
Mathematically:
The correct answer is: -18 .
________________________________________
9i * 2i = 18 i² .
________________________________________
" i " is an imaginary number equal to "√(-1) " .
" i² " = [√(-1)] ² = √(-1) * √(-1) = -1 .
________________________________________
18 * i² = 18 * -1 = -18 .
________________________________________
= (2*10) + (-3*-4) + 5 (* means multiply)
= 20 + 12 + 5
= 37
Answer: 34%
Step-by-step explanation:
Creating a table with the information will help us.
<6h of sleep - 75% reported tired | 25% reported ok
>6h of sleep - 70% reported ok | 30% reported tired
80% of all interns received <6h of sleep
Let's imagine that we have 100 interns at this hospital
<6h | >6h Total
Tired 75% of 80 30% of 20
ok 25% of 80 70% of 20
Total 80 | 20 100
<6h | >6h Total
Tired | 60 | 6 66
ok | 20 | 14 34
Total | 80 | 20 100
what percent of the interns report no feelings of tiredness during their shifts?
34/100 = 34%
