Individual : a male in the United States
Variable : income
Population : All males in the United States
Sample : 2500 males of which the information is collected
Parameter : Median income of males in the U.S
Statistic : Median income of the 2500 males sampled
- Any quality, amount, or number that can be gauged or tallied qualifies as a variable. A data item is another name for a variable.
- A sample is a subset of units chosen to represent all the individuals in a population. Because just a portion of the population was counted, it is only a partial enumeration. To estimate the characteristics of the total population of interest, data from the sampled units is used.
- A statistic is a numerical representation of a sample, whereas a parameter is a numerical representation of the entire population.

The value of x from the given circle is 4
<h3>What is intersecting chord theorem?</h3>
The intersecting chords theorem is a statement in geometry that describes a relation of the four line segments created by two intersecting chords within a circle.
It states that the products of the lengths of the line segments on each chord are equal.
According to the theorem;
x * 3 = 2 * (4 + 2)
3x = 2(6)
3x = 12
Divide both sides by 3
3x/3 = 12/3
x =4
Hence the value of x from the given circle is 4

M=d/f so,
f=d/M
f=25/.01. =2500cm
Answer:
Except 4 out of 6
the answer is the third one
N=2p
n/2=p
n-5=d
10d+5n+1p=446
subsitute n/2 for p
subsitute n-5 for d
10(n-5)+5n+n/2=446
times 2 both sides
20(n-5)+10n+n=892
expand
20n-100+10n+n=892
31n-100=892
add 100 both sides
31n=992
divide both sides by 31
n=32
subsitute back
n/2=p
32/2=16=p
n-5=d
32-5=d=27
27 dimes
16 pennies
32 nickles
