Answer:
a6 = 18,000
Step-by-step explanation:
a1 = 6
an = 5a(n-1)
a2 = 5a(2-1) = 5a1 = 5•6 = 30
a3 = 5a(3-1) =5a2 = 5•30 = 150
a4 = 5a(4-1) = 5a3 = 5•150 = 720
a5 = 5a(5-1) = 5a4 = 5•720 = 3600
a6 = 5a(6-1) = 5a5 = 5•3600 = 18000
Answer:
10%
Step-by-step explanation:
Since the question is not complete, I will be solving for probability of 3 9s
To solve this, we would be using the principle of combination, and thus
A deck of 52 hours has 4 nines, the probability that it contains at least 3 9s is mathematically represented by the equation.
P ( x ≥ 3 ) = ( 48 C 10 · 4 C 3 ) / ( 52 C 13 ) + ( 48 C 9 · 4 C 4 ) / ( 52 C 13 )
Remember I told us were going to be using the principle of combination. Well then
nCr = n!/r!(n - r)!
Now, applying the above stated formula to the equation, we have
48C10 = 48!/10!(38!)
4C3 = 4!/3!(1!)
52C13 = 52!/13!(39!)
48C9 = 48!/9!(39!)
4C4 = 4!/4!(0!)
Solving for each independently, we find that
= 0.0412 + 0.588 = 0.1
Step-by-step explanation:
Doing all that multiplying gives us a simple interest of $65.75
Answer:
57.5 MPH
Step-by-step explanation:
You have to divide to find unit rate.
You will get 57.5 once you divide.
<u>Answer:</u>
x = 5.67
<u>Step-by-step explanation:</u>
We are given a right angled triangle with a length of the hypotenuse 8 with the remaining two sides (base and perpendicular) that are equal to each other.
Assuming the two equal legs of this right angled triangle to be x, we can use the Pythagoras Theorem to find the value of x.


Taking square root at both the sides to get:


Therefore, x = 5.67.
