Answer:
The correct option is B) 26x26x10^4.
Step-by-step explanation:
Consider the provided information.
It is given that the Wisconsin consist of 2 letter and 4 digits. And two letters always precede the digits.
There are 26 Alphabet so that means for alphabets we have 26 choices also we for digits we have 10 choices (0 to 9).
However, only digits can repeat. For first letter we have 26 choices for second we have only 25 choices left, similarly for digits we have 10 choices but repetition is allow so we can choose same number. the number of possible plates are:
26×25×10×10×10×10
Which also can be written as:
Hence, the correct option is B) 26x26x10^4.
Answer:
the answer for question 1 is -7
Each of the members must raise at least $69.46.
To start they need to raise $552.50. However, they have already raised 12% of it. They only need to raise 88% of it.
552.50 x 0.88 = 486.2
Divide the remaining amount by 7 to determine how much each individual must raise.
486.2 / 7 = 69.46
Thwre are 28 clients who don not play any of the instrument using the principle of Venn distribution.
<u>Using a Venn diagram analogy</u> :
- Total number of client, U = 108
- Piano, P = 42
- Guitar, G = 51
- Piano and Guitar, (PnG) = 13
- None =?
<u>From the information given</u> :
- P only = 42 - 13 = 29
- G only = 51 - 13 = 38
<u>The total number of clients can be related thus</u> :
- Total = P only + G only + PnG + None
108 = 29 + 38 + 13 + None
108 = 80 + None
None = 108 - 80
None = 28
Therefore, the number of clients who do not play any of the instruments is 28
