The area of the remaining board is [(L × B) - (l × b)].

According to the statement

We have to find that the area of the remaining board.

So, For this purpose, we know that the

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides.

From the given information:

Suppose the bigger rectangle is labelled as ABCD and the smaller rectangle is labelled as PQRS.

And

Consider that the length and breadth of the bigger rectangle are L and B respectively. And the length and breadth of the bigger rectangle are l and b respectively.

The area of any rectangle is:

Area = Length × Breadth

The area of the bigger rectangle is:

Area of ABCD = L × B

The area of the smaller rectangle is:

Area of PQRS = l × b

Then the area of the remaining board will be:

Area of remaining board = Area of ABCD - Area of PQRS

Area of remaining board= (L × B) - (l × b)

Thus, The area of the remaining board is [(L × B) - (l × b)].

In a certain city, there are about one million eligible voters. A simple random sample of size 10,000 was chosen to study the re

Ronch [10]

Answer:

REQUIRED TEST STATICS IS 35.19

Step-by-step explanation:

total size of sample = 10,000

men women

voted 2777 3466

did not vote 1444 2313

By chi square test we can find the relationship between gender and participation in the election

$X^2 = \frac{ N(ad-bc)^2}{(a+c)(b+d)+(a+b)(c+d)}$

where

a represent = 2777, b = 3466, c= 1444, d = 2313, N = 10000

Putting values to get chis square statics

$X^2 = \frac{ 10000(2777*2313-3466*1444)^2}{(2777+1444)(3466+2313)+(2777+3466)(1444+2313)}$

$X^2 = = 35.159$

A multinational firm wants to estimate the average number of hours in a month that theiremployees spend on social media while on

elena55 [62]

Answer:

95% of the population spent between 16.8 hours to 26.2 hours on social media per month

Step-by-step explanation:

subtracting 1 from sample size: 83-1= 82
Note Mean=21.5 and standard deviation=2.5
Subtracting confidence interval from 1 and dividing by 2: (1-0.95)/2=0.025
At α=0.025 and dF=82, the t-distribution table gives 1.984
Divide standard deviation by square root of sample size: 21.5/√83= 2.36
Multiplying answer in step 4 by answer in step 5: 2.36×1.984= 4.68
For lower end: 21.5-4.68= 16.82
for upper end: 21.5+4.68=26.18
