Answer:
The answer is 11.
Step-by-step explanation:
We will use PEMDAS in this situation.
7 + 2 = x - 4 / 2
7 + 2 = x - 2 [divide first
9 = x - 2 [add the 7 and 2]
+2 +2 [the 2 cancels out]
11 = x
Your answer is 11.

The probability that the total number of heads in all the coin tosses equals 12 is 0.0273.
Given a fair dice and tossing a fair coin sixteen times.
We have to find the probability that the total number of heads in all the coin tosses equals 12.
The probability lies between 0 and 1.
Probabiltiy of coming head when the coin is tossed 1 time is 0.5 and probability of coming tails is also 0.5.
Let X shows the sum of heads while tossing.
P(X=12)=?
We can find the probability using binomial theorem.
=
We have to toss sixteen times and out of 16 times we need head 12 times.
=16!/12!4!*0.00024*0.0625
=1820*0.000015
=0.0273
Hence the probability that the total number of heads in all the coin tosses equals 12 is 0.0273.

Answer:
Somewhere between 12 and 13, perhaps 12.25
Step-by-step explanation:
This is a (rather) simple explanation:
Look for 2 square numbers that are either side of 150
In this case, it is 144 and 169
The square root of 144 is 12 and the square root of 169 is 13
Therefore we can estimate that the square root of 150 is somewhere between 12 and 13.
As 150 is a lot closer to 144 to 169, I would estimate around 12.25 but you do not need an exact value :)
Hi there.
A prime number is a number that cannot be divided into a smaller whole number aside from 1 and itself. An example would be 3; it cannot be divided into a smaller whole number unless it was divided by itself.
Let's look at the factors of 63:
1 * 63
3 * 21
7 * 9
On the left side of our multiplication table above, we have the list of prime numbers (1, 3, and 7). To the right, we don't (63, 21, and 9).
From our answer choices, we have B.) 7 included, so that is your answer.
To debunk the right side of the table:
63 can be divided into smaller numbers, which are listed above.
21 can be divided into 3 and 7.
9 can be divided into 3 and 3.
