Identify each quantity as a parameter or statistic Write "parameter" or "statistic" (without quotations). a) X: parameter b) S: statistic c) o: statistic هما d) u: parameter

Answers

Answer 1
Answer:

The classification of each quantity as either a parameteror statistic is given thus :

  • X: parameter
  • S: statistic
  • o: statistic
  • u: parameter

a) X: parameter - A numerical summary of a population, and X represents a population parameter.

b) S: statistic - A numerical summary of a sample, and S represents a sample statistic.

c) o: statistic - Similarly, "o" represents a sample statistic, as it is used to denote the sample standard deviation.

d) u: parameter - "u" represents a population parameter, often used to denote the population mean.

What are the zero(s) of the function f(x) = the quantity of 5 x squared minus 25 x, all over x? x = 5 x = 0 and x = 5

Answers

Answer:

x=5

Step-by-step explanation:

f(x)= (5x^2-25x)/(x)

To find out zeros we replace f(x) with 0

0= (5x^2-25x)/(x)

Now solve for x

first we divide the numerator by x

0=5x-25

Now we facor out GCF 5

0=5(x-5)

Divide by 5 on both sides

0=x-5

Add 5 on both sides

x= 5

zero of the function is x=5

(5x^2-25x)/x
simplify
((x)(5)(x-5))/x=5(x-5)=5x-25=f(x)
(just fyi, that x we cancled is a hole)
set to zero
5x-25=0
5x=25
divide 5
x=5

zeroe is at x=5
or (5,0)


x=5 is answer
