a student is given a reading list of ten books from which he must select two for an outside reading requirement. in how many way

Lelechka [254]

Answer:

The ways in which he can make selection = $10\times 9 =90$

Step-by-step explanation:

Student is having a list of $10$ books.

Assuming that the student can't read the same book twice.

The student has $2$ choices to make for an outside reading requirement,for his 1st choice, he had $10$ books to choose from; for his 2nd, he has $9$ books left to choose from therefore the total permutations of his choices are $=10\times 9 =90$

So the total ways in which the student can make his selection = $90$

10. The sum of three numbers is 98. The ratio of the first to the second is 2/3, and the ratio of the second to the third is 5/8

BaLLatris [955]

<h3>given:</h3>

sum of three number= 98

the second number.

<h3>solution:</h3>

Let the three numbers be x, y and z

Sum of the numbers is 98.

x + y + z = 98………………(i)

The ratio of the first to the second is 2/3.

x/y = 2/3

x= 2/3 × y

x= 2y/3

The ratio of the second to the third is 5/8.

y/z= 5/8

z/y= 8/5

z= 8/5 × y

z= 8y/5

Put the value of x = 2y/3 and z = 8y/5 in (i).

2y/3 + y + 8y/5= 98

49y/15= 98

49y= 98 × 15

49y= 1470

y= 1470/49

y= 30

Therefore, the second number is 30.

answer= option c.
