There are 4 sticks, you pick up one stick. How many sticks are left
LenaWriter [7]
There are 3 sticks because:

4 sticks is the total and when you take away 1 stick, it is
 
4 - 1, which equals 3 sticks

So, the answer is 3 sticks are left.


Question: If u are in high school, why did you ask this question? You already know 4-1=3. Im guessing it was either a joke, or u were helping other people get points. If it is the second one, thx!!

In a class of 25 students, 24 of them took an exam in class and 1 student took a make-up exam the following day. The professor g
gavmur [86]

Answer:

The  value is   \mu_n  =  73.6

Step-by-step explanation:

From the question we are told that

   The total number of students is  N =  25

    The  number of student that took exam in class is  n  = 24

    The number that took make up exam is  k  =  1

     The  average score of the first 24 students is  \mu  =  74

       The  standard deviation is \sigma  =  8.9

      The  average score of the student who took make up test is \= x  =  64

Generally the new average is mathematically represented as

      \mu_n  =  \frac{( n * \mu ) +  \= x }{N}

      \mu_n  =  \frac{( 24 * 74 ) +  64 }{25}

       \mu_n  =  73.6
