What is the probability of rolling 4 even numbers on 4 rolls of a dice

Mathematics
1 answer:
hjlf3 years ago
7 0

Answer:

1/16

Step-by-step explanation:

Possible outcomes when rolling a fair die = 1, 2, 3, 4, 5, 6 (i.e 6 possible outcomes)

Possible outcomes when rolling an even number = 2, 4, 6 (i.e 3 possible outcomes)

Hence P (rolling even number on 1 roll) = 3 / 6 = 1/2

P (Rolling 4 even numbers on 4 rolls) = (1/2)(1/2)(1/2)(1/2) = 1/16

What is the explicit formula for this geometric sequence? 8, 4 2, 1
11Alexandr11 [23.1K]

Answer:

C

Step-by-step explanation:

The standard form for the explicit formula of a geometric sequence is given by:

a_n=a\cdot(r)^{n-1}

Where a is the initial term, r is the common ratio, and n is the nth term.

Our sequence is: 8, 4, 2, 1...

So, we can see that our initial term or a is 8.

Each subsequent term is half of the previous one. So, our common ratio is 1/2.

Let's substitute 8 for a and 1/2 for r to acquire:

a_n=8\cdot(\frac{1}{2})^{n-1}

So, our answer is C.

And we're done!

HELP ME PLEASE BRAINIEST IF CORRECT BEEN STUCK ON THIS FOR HOURS AND THIS IS DUE AT 11:59pm and it is 11:46pm!!!!
Natasha2012 [34]

Here's the Answer :

  • A. linear equation

  • B. not a linear equation

  • C. linear equation

  • D. linear equation

  • E. not a linear equation

  • F. linear equation

  • G. not a linear equation

  • H. linear equation

for every linear equation value is 4 and for a non - linear equation value is 12

so, let's solve for the code :

  • \dfrac{12(4+4)+12(12+4-4)}{4}

  • \dfrac{(12×8)+(12×12)}{4}

  • \dfrac{96+144}{4}

  • \dfrac{240}{4}

  • 60

You would have 60 different types of pens with this brand. You need to multiply 12 and 5 (because you have 12 different colors for every type of tip, so you have 5 groups of 12).
