Answer: Cost Price = 21,50,000

Step-by-step explanation:

In the C programming language, the standard library procedure for reading a 32-bit signed decimal integer from standard input is scanf(). In the Python programming language, the standard library is int(input()).

An example usage of scanf() to read a 32-bit signed decimal integer from standard input is:

#include <stdio.h>

int main() {

   int my_integer;

   scanf("%d", &my_integer);

   printf("The integer is %d\n", my_integer);

   return 0;

}

An example usage of int(input()) to read a 32-bit signed decimal integer from standard input is:

my_integer = int(input())

print("The integer is", my_integer)

Other programming languages may have different procedures for reading input.

To calculate the average quality score across four agents, you need to add up the quality scores of all four agents and then divide by 4.

What is the average quality score?

. This figure is the impression-weighted average for the days you are now viewing in the report.

For example,

if agent A has a quality score of 80, agent B has a quality score of 90, agent C has a quality score of 85, and Agent D has a quality score of 75, then you would add up these scores (80 + 90 + 85 + 75 = 330) and divide by 4 to get an average quality score of 82.5.

(b) To determine if there is a difference in the number of chips per cookie between the two brands, compare the median values, the range, and the interquartile range of each brand's boxplot. If these values differ significantly, then there is a difference in the number of chips per cookie between the two brands.

(c) To determine which brand has a more consistent number of chips per cookie, compare the interquartile ranges (IQR) of each brand's boxplot. The brand with the smaller IQR has a more consistent number of chips per cookie, as the IQR measures the spread of the middle 50% of the data.

Both sides of an equation must contain the same number of atoms in order for it to be properly balanced.

An element is balanced if it has the same amount of atoms on both sides of the equation. The equation is balanced if all the components are in balance. Equal numbers and types of each atom appear on both sides of balanced chemical equations. A balanced equation must have coefficients that are the simplest whole number ratio. Chemical reactions always conserve mass.

When the quantity of each type of atom is the same on both sides of the reaction, a chemical equation is considered to be balanced. A chemical equation should have the same number of atoms on both sides. The number of atoms for each element is conserved during a chemical reaction, despite the possibility that reactant molecules may change during the process (producing distinct molecules of product).

Hope this helps!

Step-by-step explanation:

Hey there!

Answer: -4

The slope of the lines which are parallel to eachother is equal.

{i.e M1(slope of 1st equation) is equal to m2 (slope of 2nd equation)} (M1=M2)

The probability that the proportion of Labradors in a sample of 851 domestic dogs exceeds 5% is 0.0003.

This is a binomial distribution problem with parameters n = 851 and p = 0.04. We need to calculate the probability of the proportion of Labradors in the sample is greater than 5%.

Let X be the number of labs in the sample.

we need to calculate the mean μ  and standard deviation σ of X.

μ = np = 851 * 0.04 = 34.04

standard deviation:

σ = sqrt(np(1-p)) = sqrt(851 * 0.04 * 0.96) = 4.91

Now we can use the normal distribution to approximate the binomial distribution. The 5% value should be normalized.

z = (0.05 * 851 - 34.04) / 4.91 = 3.46

Find the probability that the z-score is greater than 3.46. Using a standard normal distribution table or calculator, we find this probability to be approximately 0.0003.

Therefore, the probability that the proportion of Labradors in a sample of 851 domestic dogs exceeds 5% is 0.0003.

Discrete data is a count that uses integers and has a finite number of potential values. This sort of information can't be broken down into smaller chunks. Discrete data consists of finite, numeric, countable, and non-negative integers with discrete variables.

As we know that the number of auto accidents that can be reported in a month will be always a whole number, therefore, the number of accidents can be represented as 0, 1, 2,..., 1000, etc.

Answer:

The 95% confidence interval based on this sample is =

[6.41, 7.79]

Step-by-step explanation:

The formula for Confidence Interval =

Mean ± z × standard deviation/√n

Sample mean = 7.1 hours

Standard deviation = 5 hours

n = 200 students

z = 95% confidence interval z score

= 1.96

C.I = 7.1 ± 1.96 × 5/√200

C.I = 7.1 ± 0.693

Hence, Confidence Interval

= 7.1 - 0.693

= 6.407

Approximately = 6.41

The binary representation of the number 4 is 101, which is a three-digit binary number where leftmost digit represents the MSB and the rightmost digit represents the LSB.

The binary fraction, 0.1, now has 1 added to it because the outcome is 1. The representation is finished because there is zero in the last decimal place of the number.

To convert 10 to binary, we can use the following steps:

Divide the decimal number 10 by 2. The remainder is 0, while the quotient is 5.

Write the remainder (0) as the least significant bit (LSB) of the binary representation.

To Divide the quotient (5) by 2. The remainder is 1, while the quotient is 2.

Write down the remainder (1) as the next bit in the binary representation.

As a result, 4 is represented in binary as 101

Step-by-step explanation:

If the exposed surfaces of the monument are to be covered with one-inch square tiles, A total number of   51,336 will be needed.

Therefore option H is correct.

We find the total surface area of the rectangular prism:

Length = 16 ft

Width = 4 ft

Height = 8 ft

2lw + 2lh + 2wh

= 2(16x4) + 2(16x8) + 2(4x8)

= 320 + 256 + 64

= 640 sq ft

we also find the Surface area of the square pyramid:

surface area =  1/2Pl

where P= perimeter

l =  slant height.  

Base length = 4 ft

Height = 8 ft

We find the slant height

l² = (4/2)² + 8²

l² = 4 + 64

l = √68 = 2√17 ft

surface area of each face is

surface area = 1/2* (16)* (2√17)

surface area = 64√17 sq ft.

We have 4 faces

surface area = 4* (64√17) = 256√17 sq ft

Therefore, the total surface area of the monument:

640 + 256√17 =  1055 sq ft

Since both sides are equal, we have shown that ∑(i=1 to 6) (dx_i + e) = d(∑\((i=1 to 6) x_i\)) + 6e. This represents the summation of the terms \((5x_3 + i)\) for i = 1 to 6.

To show that ∑(i=1 to 6) \((dx_i + e)\)= d(∑(i=1  \(x_i\)) + 6e, we can expand both sides and compare.

Left-hand side:

∑\((i=1 to 6) (dx_i + e) = (dx_1 + e) + (dx_2 + e) + (dx_3 + e) + (dx_4 + e) +\)(dx_5 + \(e) + (dx_6 + e)\)

                        = \(dx_1 + dx_2 + dx_3 + dx_4 + dx_5 + dx_6 + e + e + e + e\)+ e + e

                        = \((dx_1 + dx_2 + dx_3 + dx_4 + dx_5 + dx_6) + 6e\)

Right-hand side:

d(∑\((i=1 to 6) x_i)\)+ 6e = d\((x_1 + x_2 + x_3 + x_4 + x_5 + x_6)\)+ 6e

Now, let's compare the two sides:

Left-hand side: \((dx_1 + dx_2 + dx_3 + dx_4 + dx_5 + dx_6)\) + 6e

Right-hand side: d\((x_1 + x_2 + x_3 + x_4 + x_5 + x_6)\) + 6e

Since both sides are equal, we have shown that ∑\((i=1 to 6) (dx_i + e)\) = d(∑(i=1 to 6)\(x_i)\) + 6e.

To represent the equation\((5x_3 + 4) + (5x_3 + 5) + (5x_3 + 6) + (5x_3 +\)7) + \((5x_3 + 8) + (5x_3 + 9)\) using a Sigma operator notation, we can write it as:

Answer:

31.5 m

Step-by-step explanation:

Let w represent the width of the pool.

Since the length is 15 m greater than the width, it can be represented by w + 15.

Use the perimeter formula, p = 2l + 2w. Plug in the perimeter, and w + 15 as l into the formula:

p = 2l + 2w

96 = 2(w + 15) + 2w

96 = 2w + 30 + 2w

96 = 4w + 30

66 = 4w

16.5 = w

So, the width of the pool is 16.5 m. Add 15 to this to find the length:

16.5 + 15

= 31.5

The length of the pool is 31.5 m

Let the width be w

Length = w + 15

Now

Perimeter = 2(l + w)

96 = 2(w + 15 + w)

96/2 = w + 15 + w

48 = 2w + 15

48 - 15 = 2w

33 = 2w

33/2 = w

16.5 = w

Then,

Length = w + 15

Length = 16.5 + 15

Length = 31.5 m

12x + 4 = 20x - 8

20x - 12x = 8 + 4
