Two halfs equal one whole. think of it like this, an orange cut in half leaves you with two halfs, put them together and you have a whole. simple. multiplying by 2 just means adding a number two times.
1 half plus one half= 2halves= 1 whole
1half x 2= 2 halves=1 whole
The correct answer to this question is: "1/2"
You are rolling a standard number cube with numbers from 1-6. There are 3 numbers that are more than or greater than 3. This means that the other half are lesser than 3.
P(number greater than 3) = 3 / 6 = 1 / 2
So the probability of getting a number greater than 3 is 1/2

Answer:
Step-by-step explanation:
Given the set of datas 3, 7 and 2, we are to evaluate the folowing;
Σ2X – 2 and Σ(X – 1)² =where X are the individual datas.
We will substitute each of the data as value of X and ten take the sum as shown;
For Σ2X – 2
Σ2X – 2 = [2(3)-2]+[2(7)-2]+[2(2)-2]
Σ2X – 2 = (6-2)+(14-2)+(4-2)
Σ2X – 2 = 4+12+2
Σ2X – 2 = 18
For Σ(X – 1)² where x values are also 3, 7 and 2 we will have;
Σ(X – 1)² = (3 – 1)²+(7 – 1)²+(2 – 1)²
Σ(X – 1)² = 2²+6²+1²
Σ(X – 1)² = 4+36+1
Σ(X – 1)² = 41
Answer:
f(2) = 36
Step-by-step explanation:
given f(x) = 
To evaluate f(2) substitute x = 2 into f(x)
f(2) = 6² = 6 × 6 = 36
