If each data is increased by a constant K then find it's mean ?? answer fast pleaseeeeeeeeeee​
MArishka [77]

Answer:

The mean is also increased by the constant k.

Step-by-step explanation:

Suppose that we have the set of N elements

{x₁, x₂, x₃, ..., xₙ}

The mean of this set is:

M = (x₁ + x₂ + x₃ + ... + xₙ)/N

Now if we increase each element of our set by a constant K, then our new set is:

{ (x₁ + k), (x₂ + k), ..., (xₙ + k)}

The mean of this set is:

M' = ( (x₁ + k) + (x₂ + k) + ... + (xₙ + k))/N

M' = (x₁ + x₂ + ... + xₙ + N*k)/N

We can rewrite this as:

M' = (x₁ + x₂ + ... + xₙ)/N + (k*N)/N

and  (x₁ + x₂ + ... + xₙ)/N was the original mean, then:

M' = M + (k*N)/N

M' = M + k

Then if we increase all the elements by a constant k, the mean is also increased by the same constant k.

Summer used 2/5 of her ground beef to make burgers if she used 3/4 pound of beef how much did he have at first
yulyashka [42]
You need to divide 2/5 and 3/4. First, you need to do "Keep Change Flip". We do this by keeping 2/5 the same, changing the division sign to a multiplication sign and flipping 3/4 to make 4/3. Lastly, you add them up and get your answer.
2/5 ÷ 3/4
2/5 X 4/3 = 8/15

H(x) = 3х – 4<br> What is h(6)?
xeze [42]

Answer:

14

Step-by-step explanation:

h(6) means what is the value of h(x) when x is 6.

The value given for h(x) is 3x-4.

So we need to evaluate the expression 3x-4 for x=6.

Replace x with 6: 3(6)-4

Now perform order of operations.

3(6)-4

18-4
