the number of ways 15 students can be selected from a class of 32 students

Here the number of students to be selected = 15

And the total number of students = 32

So the Number of ways 15 students can be selected from a class of 32 students should be

32 C 15 ,

it means we have to solve 32 C 15 ,

for this we need to see the 15th row of the pascals triangle.

Eight times the sum of 8 and some number is 17. What is the number?
OverLord2011 [107]
Edited answer: The number is:  "- 6" .
_______________________________________________

 8 (8 + x) = 16 ;  

in which "x" represents the number for which to be solved ;

8*8 + 8*x = 16 .

Edit:  64 + 8x = 16 ;

Subtract "64" from each side of the equation:

Edit:   64 + 8x − 64 = 16 <span>− 64 ;

to get:  8x = </span>- 48 ;

Divide EACH SIDE of the equation by "8" ; to isolate "x" on one side of the <span>equation ; and</span> to solve for "x" ;

Edit:     8x / 8 = -48 / 8 ; 

  Edit:    x = - 6 .
______________________________________________
The number is:  "- 6" .
______________________________________________
 Let us check our answer, by plugging in "-6" for "x" in the original equation:
______________________________________________
8 (8 + x) = 16 ; 

→ 8 [8 + (-6) ]  =? 16 ?? ; 

→ 8 (8 − 6 )  =? 16 ?? ; 

→ 8 (2)  =? 16 ?? ; 

→ 16 = ? 16 ??  Yes!

What number increased by 62%, results in the value of 59.94
lakkis [162]

Answer:

The number is : x = 37

Step-by-step explanation:

In order to solve this question, we may set up a proportion.

If the original number is 100%, 59.94 would be 162% of the original, as it was increased by 62%.

so

59.94 → 162%

x → 100%

solving the proportion gives you  

59.94 × 100 = 162 × x

x = (59.94 × 100)/162

x =  5994/162

x= 37

Thus, the number is : x = 37
