Answer:
The question continues ; I take it is defined as a set of five white and one red number how many possible different Powerball tickets can be purchased how many possible different winning Powerball tickets are there
Step-by-step explanation:
he concept of combinatorics ( combination and permutation) is applied her
nPr = n!/(n-r)!
nCr = n!/(n-r)!r!
Hence number of possible different powerball tickets = number of ways of selection
= selecting 5 white ball from a total of 69 and selecting a red ball from a total of 26
= 69C5 x 26C1
using the formula above for combination
= 69!/(69-5)!5! x 26!/(26-1)!1!
= 292, 201, 338 ways
Answer:
since, hcf(312, 37) = 1
therefore, the answer will come in decimal form.
i.e., 8.4324324324
Answer:
The two numbers are - 12 and - 12 .
Step-by-step explanation:
Let the two numbers be x and y then
By the question
x * y = 144
or x = 144 / y ....... I)
Again
x + y = - 24
Or 144/y + y = - 24
or, ( 144 + y²) / y = - 24
or, 144 + y² = - 24y
y² + 24y + 144 = 0
y² + ( 12 + 12 ) y + 144 =0
y² + 12y + 12y + 144 = 0
y(y + 12 ) + 12 ( y + 14) = 0
( y + 12 ) ( y + 12 ) = 0
Either
y + 12 =0
y = - 12
Now
x = 144 / - 12 = - 12
Therefore the two numbers are - 12 and - 12 .
Hope it will help :)❤
