Answer:
Therefore, option C is correct
Step-by-step explanation:
Budgeted cash receipts for February = 60000 + 303800*0.40 + 274400*.60
= 60000 +121520 + 164640
= 346160
We have to simplify:
√ ( - 28 )
We know that √ (-1 ) = i ( the imaginary unit )
√ ( - 28 ) = √ 28 * ( - 1 ) = i √ ( 28 ) = i √ ( 4 * 7 ) = 2 i √( 7 )
But there is not such solution among the options.
Only correct answer ( using the imaginary unit ) is:
C. i (square root) 28
Answer:
Step-by-step explanation:
Given
Number of Girls : 0 ----> 1 -----> 2 ------->3
Number of Families: 112 -> 314 --> 382 ---> 192
Solving (a): At most one girl
From the table, the number of families with at most one girl is: 112 + 314
i.e.
Number of Girls : 0 ----> 1
Number of Families: 112 -> 314
So, we have:
The probability is then calculated as:
Solving (b): More girls
From the table, the number of families with more girl is: 382 + 192
i.e.
Number of Girls : -----> 2 ------->3
Number of Families: --> 382 ---> 192
So, we have:
The probability is then calculated as:
Answer:
5 people
Step-by-step explanation:
Let's find LCM of 4, 10 and 20:
- 4 = 2*2
- 10 = 2*5
- 20 = 2*2*5
LCM(4,10,20) =2*2*5 = 20
There are 100/20 = 5 twenties in 100
So every 20th person will get all 3 prizes, in total 5 people
