Answers

Answer 1

Answer: There would be at least 92 million people who will own a computer in 2015.

I don't know how to make a function out of a percentage, that is why I used excel to compute annual population.

Answer:

MARK ME BRAINLIEST!!

Step-by-step explanation:

To compare the functions f(x) and g(x) based on the given tables, we need to determine whether each function is one-to-one or not.

A function is considered one-to-one if each input (x-value) corresponds to a unique output (y-value), and no two different inputs produce the same output.

Looking at the table for f(x):

x: 0 1 2 3 4 5

f(x): 15 14 X 8 X

In the given table for f(x), the value of f(x) is missing for x = 2 and x = 4. This indicates that multiple inputs (2 and 4) are producing the same output. Therefore, f(x) is not one-to-one.

Now, let's analyze the table for g(x):

x: 0 1 2 3 4 5

g(x): 8 12 9 13 16 18 21 19 8

In the given table for g(x), there are no repeated output values. Each input corresponds to a unique output, indicating that g(x) is one-to-one.

To summarize, f(x) is not one-to-one, while g(x) is one-to-one.

A student conducted a survey of all 500 employees in a company. He calculated the population mean of the number of cars they owned to be x%. He calculated the proportion of employees who drove a car to work to be y%. Another student conducted a survey of a sample of 10 employees in the same company. She found the sample mean of the number of cars they owned to be p%. She found the sample proportion of employees who drove a car to work to be q%. Which parameter would be considered to be point estimates?
a. x and p
b. x and y
c. y and p
d. y and q
e. p and q

Answers

The correct answer for the question that is being presented above is this one: "c. y and p." A student conducted a survey of all 500 employees in a company. He calculated the population mean of the number of cars they owned to be x%. He calculated the proportion of employees who drove a car to work to be y%.

A number cube is rolled. What is the probability of rolling a 2,3, or 5?

Answers

Well if the number cube goes up to 6 like most number cubes, then the probability would be 3/6 because there are 3 numbers that you want to roll (2, 3, and 5) out of 6 total numbers (1-6). Then 3/6 can be further simplified to 1/2. So the answer should be 1/2.

Convert this franction into a percentage 9/12?

Answers

Hello, Yoloalanis. In order to solve this question that you have just posted, you only have to do a few simple steps. So, We can do this!

Let's start with your fraction. You will first have to change 9/12 into a decimal. In order to do this, you will have to divide the numerator by the denominator. A numerator is also known as the top part of the fraction. A denominator is the bottom part of the fraction. So, when you divide nine by twelve, you get 0.75 as a decimal. Now, you just have to multiply the decimal by 100 or to make it simpler, just move the decimal two places to the right. To sum it all up, you will get 75%.

Hope it helps :)

$\bold{ (9)/(12)(100)} \n \n \Bigg( (9)/(12) \Bigg)\Bigg((100)/(1) \Bigg) \n \n \bigg( (3)/(4)\bigg) \bigg( (100)/(1)\bigg) \n \n \n \Bold{ ((3)(100))/((4)(1)) } \n \n (300)/(4) \n \n \boxed{\pmb{{=75}}}$
