Lee has a bag with 500 quarters. Some are the older eagle quarters, and others are the newer state quarters. She pulls out 10 qu

Answer:

The mean and center will be nearly identical, while the variability in simulation B will exceed that of simulation A.

Step-by-step explanation:

Solution

In general, the size of the sample significantly influences the distribution.

As a guideline, by quadrupling the sample size, the sampling error typically reduces by half.

Here, simulation B has a sample size that is twice that of simulation A.

Thus, the sampling error related to the mean is affected, and it stands that A does not have a greater value.

However, its sample size is considerable for this context, making them nearly equal.

Additionally, increased trials lead to decreased variability in simulation. A displays lesser variability.

As trial numbers increase, variability in simulation declines, hence A has lesser variability.

D1,..,d9 = 0,0,2,2,2,3,4,6,8 //there are 9 values, presented in ascending order
Q2 (median) = d5 = 2 //middle value
Q1 = (d2+d3) / 2 = (0+2)/2 = 1
(Q1 represents the median of d1,d2,d3,d4, but as there is no singular middle element among four, the average is computed)
Q3 = (d7+d8) / 2 = (4+6)/2 = 5
interquartile range = IQR = Q3 - Q1 = 5 -1 = 4
final answer: 4

You can utilize them in reverse order, but this method doesn't apply for subtraction.

According to the given ratio, the lengths of the sides are:

25x + 14x + 12x equals 170

51x equals 170

x equals 170 divided by 51

x equals 3 1/3

Thus, the lengths of the sides are: 25 times 3 1/3 equals 83 1/3 feet.

14 times 3 1/3 equals 46 2/3 feet.

12 times 3 1/3 equals 40 feet.

By employing Heron’s formula,

the semi-perimeter (S) is calculated as 170 divided by 2, yielding 85 ft.

Thus, the area of the triangle is given by SQRT(S*(S-83 1/3)*(S-46 2/3)*(S-40)).

This results in SQRT(85*(85-83 1/3)*(85-46 2/3)*(85-40)).

This simplifies to SQRT(85*1 2/3*38 1/3*45).

= SQRT(244374).

= 494.34 square feet (round as necessary).

The solution is 15 boxes!
