A force is applied to a door knob and the door swings open about its hinge.

The population increased by 18 million at the end of one year at the rate of 1.8%.

The Latin word "per centum," which means "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. Alternatively put, it is the relationship between a component and a whole in which the value of "whole" is always assumed to be 100.

For instance, if a student receives 15 out of 50 in math, one can determine the relevant percentage by expressing "marks earned" as a fraction of "total marks" and multiplying the result by 100. i.e., the percentage of marks is equal to 15 / 50 100, or 30%.

Given that, population of India is one billion.

The rate of increase is 1.8%.

After one year the population will be:

P = (1000000000)(1.8/100)

P = 18000000

Hence, the population increased by 18 million at the end of one year at the rate of 1.8%.

Step-by-step explanation:

the parentheses are there so you know the two arent beside each other

The number of tennis matches that she could have won before the weekend began is 0.

Before the weekend, the player had a win ratio of 0.500, which indicates that she had won exactly as many games as she had lost. Call this number x for now. She has so lost x matches in addition to the x matches she won before to the weekend.

She competes in three matches during the course of the weekend and loses one, bringing her overall win total (after the weekend) to x + 3 and her overall loss total (after the weekend) to x + 1. Consequently, her weekend victory ratio is

\(\frac{(x + 3)}{(x + 1)}\)

= \(\frac{(3x + 3)}{(x + 1) }\)

= \(\frac{3x }{x + 1 }\)

= \(\frac{3}{\frac{1}{x+1} }\)

given that this value is greater than 0.503,

Thus,

\(\frac{3}{\frac{1}{x+1} }\) > 0.503

Simplifying,

\(\frac{3}{\frac{1}{x+1} }\)> 0.503 - 1

= -0.497

Further,

\(\frac{3}{\frac{1}{x+1} }\) > -0.497

\(\frac{3}{\frac{1}{x+1} }\) is equivalent to 3x

This inequality can be written as

3x > -0.497

3x is positive, dividing on both sides by 3 we get

x > -0.497 / 3

Simplifying,

x > -0.166

The least value of x that meets this inequality is 0, as x, the number of matches won, must be a positive integer. Thus, the maximum number of games the player might have won prior to the start of the weekend is x = 0, and the response is 0.

Answer:

164

Step-by-step explanation:

Let n be the number of matches she won, and m be the number of matches she played. Then, n/m = 1/2 and (n + 3) / (m + 4) > 0.503. By the first equation, 2n = m. Substituting m = 2n into the second equation/inequality, we get (n + 3) / (2n + 4) > 0.503. Because n cannot be negative in this context, we can multiply both sides by (2n + 4). We get n + 3 > 0.503 (2n + 4). Distributing the right-hand side, we get n + 3 > 1.006n + 2.012. Solving this inequality gives us 0.006n < 0.988, or n < 164.666667. n must be a whole number, so the greatest n you can achieve is 164.

On an actual test, you can also check using answer choices if given them. 164 gives around 0.50301, so it is 164, or cannot be determined. Then it is a 50/50 guess, and 164 is most likely the correct answer, which in this case, is the correct answer.

Answer:

3:7

Step-by-step explanation:

Let x = pounds of the $10 rice in the mixture

Let y = pounds of the $30 rice in the mixture

Total cost of the $10 rice = 10x

Total cost of the $30 rice = 30y

(10x + 30y) / (x + y) = 24

Solve this equation for y/x:

10x + 30y = 24(x + y)

10x + 30y = 24x + 24y

30y - 24y = 24x - 10x

6y = 14x

y/x = 6/14  simplify the fraction

y/x = 3/7

So, the ratio of the two different types of rice (y:x) is 3:7, meaning a pound of the rice mixture has 3 parts of the $30 rice to 7 parts of the $10 rice.

a. A two-sample z-test for a difference in sample proportions

Step-by-step explanation:

We are told that there are two supermarkets in the research named X and Y.

That a random number of shoppers were selected in each supermarket.

Thus means we have two different sample proportion.. Since a different number of people were randomly selected from each supermarket and a different number of people purchased the product.

Thus, we will have 2 sample proportions one for supermarket X and the other for supermarket Y.

In addition, the position of the product was different in both supermarkets.

Thus, we can say that this is a 2 sample Z-test for difference in their sample proportion.

The option that is most appropriate method for analyzing the results is that a two sample z test for a difference in population proportions.

A Two-Sample Z-test is known to be a kind of test that is often employed so as to make a comparison of the means of two samples to know and show if it is feasible that they are a product of the same population.

Therefore, the quotient when x³ - x² - 3x + 2 is divided by x - 2 is x² - 2x - 5 with a remainder of -3.

To find the quotient when x³ - x² - 3x + 2 is divided by x - 2, we will use the long division method. Here is the solution:  

Step 1: The first term of the quotient is x². Multiply x² by x - 2 to get x³ - 2x². Subtract this product from x³ - x² to get: x² - 3x² = -2x²

Step 2: Bring down the next term of the dividend, which is -3x. The new dividend is -2x² - 3x.

Step 3: The second term of the quotient is -2x. Multiply -2x by x - 2 to get -2x² + 4x. Subtract this product from -2x² - 3x to get -5x.

Step 4: Bring down the last term of the dividend, which is +2. The new dividend is -5x + 2. Step 5: The third term of the quotient is -5. Multiply -5 by x - 2 to get -5x + 10. Subtract this product from -5x + 2 to get -3.

(a) The probability of the company becoming a successfully approved supplier to Ford Motor Company is 0.2048.

(b) The probability of the company becoming a successfully approved supplier to General Motors Company is 0.2448.

Step-by-step explanation:

A local startup company working on a smart dashboard camera system is bidding to be a supplier for both Ford Motor company and General Motors.

Both the companies have a two-tier system where suppliers are approved in two separate phases.

It is provided that a company can move on to Phase II if they have passed the Phase I phase.

(a)

The chances of landing with a supplier contract with Ford Motor Company is 32% in Phase I while it is 64% in Phase II.

That is:

P (Phase I) = 0.32

P (Phase II | Phase I) = 0.64

Consider the tree diagram below.

Compute the probability of the company becoming a successfully approved supplier to Ford Motor Company as follows:

P (Supplier to Ford Motor Company) = P (Phase II | Phase I) × P (Phase I)

                                                             \(=0.64\times 0.32\\=0.2048\)

Thus, the probability of the company becoming a successfully approved supplier to Ford Motor Company is 0.2048.

(b)

The chances of landing with a supplier contract with General Motors is 68% for Phase I and 36% for Phase II.

That is:

P (Phase I) = 0.68

P (Phase II | Phase I) = 0.36

Consider the tree diagram below.

Compute the probability of the company becoming a successfully approved supplier to General Motors as follows:

P (Supplier to General Motors Company) = P (Phase II | Phase I) × P (Phase I)

                                                                    \(=0.36\times 0.68\\=0.2448\)

Thus, the probability of the company becoming a successfully approved supplier to General Motors Company is 0.2448.

Answer:

Mean : 79/15 or about 5.27

Median : 5

Mode : 9

Range : 8

Step-by-step explanation:

To make this easy lets first list the data points

We have 1 , 2 , 2 , 3 , 4 , 4 , 5 , 5 , 6 , 6 , 7 , 7 , 9 , 9 , 9

Now lets find each data value

First the mean

Mean = average which = sum of data points / # of data points

Sum of data points = 1 + 2 + 2 + 3 + 4 + 4 + 5 + 5 + 6 + 6 + 7 + 7 + 9 + 9 + 9 = 79

# of data points ( count the number of dots ) = 15

So average (mean) = 79/15 or about 5.27

Next lets find the median.  

The median is the middle value.

We can find the median by listing the values and then meeting at the middle of the values

So we have 1 , 2 , 2 , 3 , 4 , 4 , 5 , 5 , 6 , 6 , 7 , 7 , 9 , 9 , 9

If you go to the very middle, 5 is the middle value so median = 5

Next lets find mode

Mode is simply the value that appears most.

The value that appears the most is 9 as it appears three times which is the most out of any other value

Finally lets find the range.

Range = Largest number - Smallest number

Largest number = 9

Smallest number = 1

Range = 9 - 1 = 8
