So the equation 12 y equals 132 the equation 12 y equals 132
OlgaM077 [116]
12y = 132

Now, solve for y.

Do the inverse operation.

12y = 132
12y/12 = 132/12
y= 132/12
y= 11

Equation: 12y = 132
Y equals: 11

Experimental probability is the result of an experiment. Theoretical probability is what is expected to happen.
Oxana [17]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete, and it can be interpreted in different ways.</em>

Is the question a true or false question?

If yes, then both statements are true

As a further explanation, we consider a roll of die.

The sample space is:

S = \{1,2,3,4,5,6\}

Because 1 to 6 appear just once on the die, then each have a probability of 1/6

Pr = \frac{1}{6} --- This is referred to as the theoretical probability

But if after rolling the die 6 times, the outcome is:

Outcome = \{1,1,4,5,1,2\}

The experimental probability of (say 1) is, the number of times 1 appeared divided by the number of times the experiment is carried out.

i.e.

Pr(1) = \frac{3}{6}

a certain arithmetic sequence has the following explicit formula for the nth term: an = 2 + (n - 1)(6) The same sequence has the
MrMuchimi

Answer:

A. 6

Step-by-step explanation:

The formula for nth arithmetic sequence =

aₙ = a₁+(n - 1) d

a₁ = First term

n = number of terms

d = common difference

In the question above, explicit formula for the nth term:

aₙ = 2 + (n - 1)(6)

This means, the first term a1 = 2

d = 6

The same sequence has the following recursive formula:

aₙ = aₙ₋₁+ ___

The formula for a recursive formula is

aₙ= aₙ₋₁+ d

Where the common difference from the nth term = 6

Therefore , the number that belongs in the blank space in the recursive formula is 6
