120 groups <span>(10*9*8/3*2*1=120) </span>of 3 (k) operators are possible to make from the 10 (n) qualified employees. This problem can be solved using the combination formula in mathematics which is to find the possible number of combination (group of operator) from a set of choices. (Formula : n*(n-1)*...* (n-k+1)/ k!).

8h+(-6.3d)-15+4d-3.3h
Drupady [299]

Answer:

Not exactly sure if you are asking to simplify, but that is all I can do with the information you have given.

Here is the simplified version:

−2.3d + 4.7h − 15

Step-by-step explanation:

Combine Like Terms:

=8h+−6.3d+−15+4d+−3.3h

= (−6.3d+4d) + (8h+−3.3h) + (−15)

= −2.3d+ 4.7h − 15

A bag contains 10 red 6 green 12 orange and 8 purple candy's without looking Ann pulls one piece of candy out of the bag what is
Alex73 [517]

Answer:

\frac{1}{6}

Step-by-step explanation:

GIVEN: A bag contains 10 red 6 green 12 orange and 8 purple candies, without looking Ann pulls one piece of candy out of the bag.

TO FIND: what is the probability that she pulls out a purple piece of candy.

SOLUTION:

Total number of candies in the bag =36

Total number of purple candies in the bag =6

Now,

Probability that Ann pulls out a purple piece of candy

                                                                                        =\frac{\text{number of purple candies}}{\text{total candies in bag}}

putting values,

                                                                                        =\frac{6}{36}

                                                                                        =\frac{1}{6}

Hence, the probability that she pulls out a purple piece of candy is   \frac{1}{6}

Fill in the gaps in this sequence: -8, -19, -30, _ , _.<br> (Geometric and arithmetic sequences)
Alika [10]

-8, -19, -30, -49 , -60

<u>Step-by-step explanation:</u>

Here we have the following sequence :

-8, -19, -30, _ , _

  • First term of sequence is -8 .
  • Second term of sequence is -19 : -8-11 = -19
  • Third term of sequence is -30 : -19-11 = -30
  • Fourth term of sequence is : -30-11 = -49
  • Fifth term of sequence is : -49-11 = -60  

Following sequence was an AP( Arithmetic Progression ) with first term as -8 i.e. a = -8 and common difference d = -11 having general equation as : -8 -11n .
