Q #...10 somebody help me

Answers

The slope of a line can be found, given two points, as follows:

$P_(1)(-5.5,6.1) \n \n P_(2)(-2.5,3.1) \n \n m=(y_(2)-y_(1))/(x_(2)-x_(1)) \n \n m=(3.1-6.1)/(-2.5-(-5.5))=-1$

So this slope tells us the direction of a line and represents the vertical change divided by the horizontal change.

It is -1, at least thats what i got i hope this helped

Sleeping in college. A recent article in a college newspaper stated that college students get an average of 5.5 hrs of sleep each night. A student who was skeptical about this value decided to conduct a survey by randomly sampling 25 students. On average, the sampled students slept 6.25 hours per night. Identify which value represents the sample mean and which value represents the claimed population mean.

Answers

Answer:

Sample mean = 6.25 hours per night.

Population mean = 5.5 hrs of sleep each night.

Step-by-step explanation:

A sample mean is the mean of the sample collected. The 25 students surveyed by the student is the sample. The average sleep time derived from the sample is the sample mean.

A population mean is the mean of all the population. Here the population are college students. The population mean is the mean derived from studying the sleep duration of all the population - college students

The graph below shows the numbers of cups of apple juice that are mixed with different numbers of cups of lemon-lime soda to make servings of apple soda: A graph is shown. The values on the x axis are 0, 1, 2, 3, 4, 5. The values on the y axis are 0, 6, 12, 18, 24, 30. Points are shown on ordered pairs 0, 0 and 1, 6 and 2, 12 and 3, 18 and 4, 24. These points are connected by a line. The label on the x axis is Lemon -Lime Soda in cups. The title on the y axis is Apple Juice in cups. What is the ratio of the number of cups of apple juice to the number of cups of lemon-lime soda? 1:24 24:1 1:6 6:1

Answers

The ratio of the number of cups of apple juice to the number of cups of lemon-lime soda is 6:1

What is the ratio?

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

Given that x axis denotes Lemon lime soda in cups and y axis denotes Apple juice in cups

(x) Lemon -Lime Soda ; 0, 1, 2, 3, 4, 5

(y) Apple Juice : 0, 6, 12, 18, 24, 30

Therefore, the ratio can be written as;

the number of cups of apple juice : the number of cups of lemon-lime soda

6 : 1

Then, ratio is 6:1

Hence, the ratio of the number of cups of apple juice to the number of cups of lemon-lime soda is 6:1
