If 2x⁴ + 2y⁴ + 2z⁴ = 144, what is the mean of x⁴, y⁴ and z⁴

Margarita [4]

Answer: 24

Step-by-step explanation:

Given

$2x^4+2y^4+2z^4=144$

dividing whole equation by 2, we get

$\Rightarrow x^4+y^4+z^4=72$

Mean is given by the sum of the value of entities divided by the total no of entities

$\Rightarrow \text{Mean}=\dfrac{x^4+y^4+z^4}{3}\\\\\Rightarrow \text{Mean}=\dfrac{72}{3}\\\\\Rightarrow \text{Mean}=24$

Find g(x), where g(x) is the translation 8 units down of f(x)=x2.

SVEN [57.7K]

Answer:

g(x) = x² - 8

g(x) = 1(x-0)² - 8

Step-by-step explanation:

f(x) = x²

we translate this parent function 8 units down thus:

g(x) = f(x) - 8

g(x) = x² - 8

in the form a( x - h)² + k:

g(x) = 1(x-0) - 8

k = (-8)

As the change is constant rather than the variable of the quantity of "x" It is a movement of the whole f(x) function eight units down.

h = 0

Because, there is no information about a stretchment of the parent function in g(x)

djverab [1.8K]

Answer:

Number: 0, 1, 2, 3, 4, 5, 6, 7, 8

Frequency: 6, 12, 13, 15, 5, 3, 3, 1, 1

b. The proportion of the batches that have at most is 0.864

Step-by-step explanation:

a. The given data are;

2 1 2 3 1 1 3 2 0 5 3 3 1 3 2 4 7 0 2 3

0 4 2 1 3 1 1 3 4 1 2 3 2 2 8 4 5 1 3 1

3 0.254

4 0.085

5 0.051

6 0.051

7 0.017

8 0.017

b. The proportion of the batches that have at most 4 is given as follows;

The number of the batches that have at most 4 = 6 + 12 + 13 + 15 + 5 = 51

Therefore, the proportion of the batches that have at most 4 = 51 / 59 = 0.864.
