Answer:
43/70
Step-by-step explanation:
Total number of times spun = 14 + 12 + 16 + 15 + 13 = 70
Total number of times spun that yielded a odd number (1,3,5) = 14 + 16 + 13 = 43
The probability of spinning an odd number = total number of spins that yielded 1,3,5 ÷ total number of spins yielding all values from 1 to 5
= 43 / 70
Answer:
65625/4(x^5)(y²)
Step-by-step explanation:
Using binomial expansion
Formula: (n k) (a^k)(b ^(n-k))
Where (n k) represents n combination of k (nCk)
From the question k = 5 (i.e. 5th term)
n = 7 (power of expression)
a = 5x
b = -y/2
....................
Solving nCk
n = 7
k = 5
nCk = 7C5
= 7!/(5!2!) ------ Expand Expression
=7 * 6 * 5! /(5! * 2*1)
= 7*6/2
= 21 ------
.........................
Solving (a^k) (b^(n-k))
a = 5x
b = -y/2
k = 5
n = 7
Substituting these values in the expression
(5x)^5 * (-y/2)^(7-5)
= (3125x^5) * (-y/2)²
= 3125x^5 * y²/4
= (3125x^5)(y²)/4
------------------------------------
Multiplying the two expression above
21 * (3125x^5)(y²)/4
= 65625/4(x^5)(y²)
Standard form is ax+by=c
mnus 7y both sides
6x-7y=0
The numbers on the top depend on how many sides a dice has. Hope this helps.
2 = 2????
Thats what Im getting it from.
Since x is 2 then it would still be 2=2 in simple term.
