Exercise 10.10.2: Distributing a coin collection. About A man is distributing his coin collection with 35 coins to his five gran
11Alexandr11 [23.1K]

Answer:

Step-by-step explanation:

Given that:

all coins are same;

The same implies that the number of the non-negative integral solution of the equation:

x_1+x_2+x_3+x_4+x_5 = 35

x_1 > 0 ;  \ \ \ x_1 \  \varepsilon  \ Z

Thus, the number of the non-negative integral solution is:

^{(35+3-1)}C_{5-1} = ^{39}C_4

(b)

Here all coins are distinct.

So; the number of distribution appears to be an equal number of ways in arranging 35 different objects as well as 5 - 1 - 4 identical objects

i.e.

= \dfrac{(35+4)!}{4!}

= \dfrac{39!}{4!}

(c)

Here; provided that the coins are the same and each grandchild gets the same.

Then;

x_1+x_2+x_3+x_4+x_5 = 35

x_1 > 0 ;  \ \ \ x_1 \  \varepsilon  \ Z

x_1=x_2=x_3=x_4=x_5

5x_1 = 35\\\\ x_1= \dfrac{35}{5} \\ \\  x_1= 7

Thus, each child will get 7 coins

(d)

Here; we need to divide the 35 coins into 5 groups, this process will be followed by distributing the coin.

The number of ways to group them into 5 groups = \dfrac{35!}{(7!)^55!}

Now, distributing them, we have:

\mathbf{\dfrac{35!}{(7!)^55!}  \times 5!= \dfrac{35!}{(7!)^5}}

If an exercise routine requires 24 crunches for every 16 squats, how many squats would need to be done for every 78 crunches? Gr
Angelina_Jolie [31]

Answer:

The correct answer is 52 squats.

Step-by-step explanation:

An exercise routine requires 24 crunches for every 16 squats.

Therefore the routine would require 1 crunch for every \frac{16}{24} squats.

And by the use of unitary method, the routine would require 78 crunches for every \frac{16}{24} × 78 squats = 52 squats.

Thus for every 78 crunches attempted, the exercise routine would requires 52 squats to be done.

A picture frame has an area of 3 2/3 square inches and a width of 1 1/4 inches. What is the picture frame's length?
Veseljchak [2.6K]

Answer:

Step-by-step explanation:

3⅔ = 11/3

1¼ = 5/4

length = area ÷ width

= (11/3) ÷ (5/4)

= (11/3) × (4/5)

= 44/15

= 2 14/15 inches

MO bisects angle LMO = 6x-22, and angle NMO = 2x + 34. solve for x and find angle LMN.
myrzilka [38]

Step by step explanation

1) 6x-22=2x+34  both the angles are equal to each other because when you biset an angle you break it up into 2 equal parts

2) 4x=56 Collect like integers

3) x=14 Divide both sides by 4 to get x by itself

The answer is x=14
