Answer: Sample statistics are used to make inferences about population parameters.


Step-by-step explanation:

A number which describes a population is called a parameter, such as a proportion or percentage.

A statistic is a number which may be calculated from the data observed in a random sample without demanding the use of any unknown parameters.

The mean and variance of a population are population parameters.

Thus, fourth statement is the right answer "Sample statistics are used to make inferences about population parameters."

Số tiếp theo (next number?): 25 50 99 196 388
Delvig [45]

Answer:

The correct answer is - 768.

Step-by-step explanation:

The given question is based on a specific pattern present in between the numbers in the given series -

Series = 25 50 99 196 388

to find - next number in series

let us find the relation between the initial two number:

25 - 50, here number 50 is two times of 25 or (x*2-0)

relation between 2nd and 3rd number:

50 - 99, here 99 is two times of 50 minus 1 or (x*2-1)

relation between 3rd and 4th number:

99 - 196, here 196 is two times of 99 minus 2 or (x*2-2)

relation between 4th and 5th number:

196 - 388, here 388 is the two times of 196 minus 4 or (x*2-4)

So on this pattern, the next number would be = x*2-8

388*2-8

= 768

Popular Problems Algebra Find the Axis of Symmetry f(x)=x^2-5 f(x)=x2−5 Set the polynomial equal to y to find the properties of the parabola. y=x2−5

Rewrite the equation in vertex form.

y=(x+0)2−5 Use the vertex form,  y=a(x−h)2+k, to determine the values of a, h, and k.a=1h=0k=−5

Since the value of a is positive, the parabola opens up.

Solve: 5h + 2(11 - h) = -5 *<br> h = -9<br> h = 9<br> h = -8<br> h = 8
BigorU [14]

Answer:

-9

Step-by-step explanation:

do distributive property first to eliminate the parenthesis.

5h + 22 - 2h = -5

combine like terms

3h + 22 = -5

move the 22 over by subtraction

3h = -27

divide

h = -9
