For statictics of Out of 780 smokers, 376 have been divorced, Non-smokers: Out of 2855 non-smokers, 902 have been divorced, the 95% confidence interval for smokers and non-smokers is mathematically given as

Generally, the equation for the Confidence interval is mathematically given as

p ± Z/2[p(1-p)]/n

Where

Z1/2=1-(0.05/2)

Z1/2=0.975

Read z table we have

Z score= 1.96

Hence

0.4907 ± 1.96 (0.4907)(1-0.4907)/485

0.4907±0.0445

Therefore

95% confidence interval = (0.5352, 0.4462)

b)

Z1/2 = 1- (0.05/2)

Z1/2 = 0.975

Z score= 1.96

0.3159 ± 1.96 (0.3159)(1-0.3159)/1184

0.3159±0.0265

Thereofore

95% confidence interval = (0.3424, 0.2894)

c)

In conclusion, The 95% confidence interval helps us read that 53% increased risk of divorce for smokers.

The volume of water contained in this aquarium that is filled halfway through its height is equal to 141,750 cm³.

Mathematically, the volume of a right prism is calculated by using this formula:

Volume = length × width × height

Given the following data:

Based on the information, the aquarium is filled halfway through its height. Thus, the height of water is given by:

H = 70 × 0.5

H = 35 cm.

Substituting the parameters into the formula, we have;

Volume = 45 × 90 × 35

Volume = 141,750 cm³.

Mathematically, the volume of Elisha's swimming pool is given by:

Volume = length × width × height

Volume = 10 × 5 × 1

Volume = 50 m³.

Now, we can calculate the cost of water supply:

Cost = 27.25 × 50 × 10³

Cost = P1,362,500.

Mathematically, the volume of a rectangular prism is given by this formula:

Volume = length × width × height

Volume = 130 × 70 × 110

Volume = 1,001,000 cm³.

Firs of all, we would determine the volume of this truck:

Volume = length × width × height

Volume = 9 × 7 × 5

Volume = 315 ft³.

Now, we can calculate the number of trips:

Number of trips = 945/315

If the total profit per month is Rs 200,000 and the revenue per month can be obtained twice the cost per month minus 50,000 then  the revenue per month is 2083 and the cost per month is 25000

Two or more expressions with an Equal sign is called as Equation.

Given,

If the total profit per month is Rs 200,000

Revenue per month can be obtained twice the cost per month minus 50,000

2x-50000

2x=50000

x=25000

So cost per month is 25000

The revenue per month is 25000/12

2083

Hence, the revenue per month is 2083 and the cost per month is 25000

Using it's concept, it is found that the relative frequency of landing on heads is 0.48 and of landing on tails is 0.52.

A relative frequency is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, out of 50 flips, 24 landed on heads and 26 on tails, hence:

Fh = 24/50 = 0.48.

Ft = 26/50 = 0.52.

The relative frequency of landing on heads is 0.48. The relative frequency of landing on tails is 0.52.

Ratio of cakes baked by Calvin and Susie = 3 : 7

Cakes baked by Calvin = 3x

Cakes baked by Susie = 7x

Cakes baked by Calvin = Cakes baked by Susie - 60

3x = 7x - 60

7x - 60 = 3x

7x        = 3x  + 60

7x - 3x = 60

The common denominator of 5/8 and 5/4 is 8.

4×2 is 8 and 5/8 already has a denominator of 8

The common denominator of two fractions 5/8 and 5/4 is 8.

A number system is defined as a system of writing to express numbers.

To find a common denominator for 5/8 and 5/4, we need to find the least common multiple (LCM) of the denominators 8 and 4.

The multiples of 8 are: 8, 16, 24, 32, 40, 48, ...

The multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, ...

We can see that the least common multiple of 8 and 4 is 8, since 8 is the smallest number that appears in both lists.

To convert 5/8 to an equivalent fraction with denominator 8, we can multiply both the numerator and the denominator by 1, which is equivalent to multiplying by 8/8

Hence, the common denominator of two fractions 5/8 and 5/4 is 8.

The  rectangles have the same areas but greater perimeters are 12 ft by 3 ft, 9 ft by 4 ft and 18 ft by 2 ft.

Area is the amount of space occupied by a two dimensional shape or object.

A rectangle is shown with a length and height of 6 ft. Hence:

Area = (6 * 6) = 36 ft²

Perimeter = 2(6 + 6) = 24 ft

For 12 ft by 3 ft:

Area = (12 * 3) = 36 ft²

Perimeter = 2(12 + 3) = 30 ft

For 9 ft by 4 ft:

Area = (9 * 4) = 36 ft²

Perimeter = 2(9 + 4) = 26 ft

For 8 ft by 3 ft:

Area = (8 * 3) = 24 ft²

Perimeter = 2(8 + 3) = 24 ft

For 7 ft by 4 ft:

Area = (7 * 4) = 28 ft²

Perimeter = 2(7 + 4) = 26 ft

For 18 ft by 2 ft:

Area = (18 * 2) = 36 ft²

Perimeter = 2(18 + 2) = 40 ft
