A text book publisher wants to estimate the number of sentences per paragraph in a history textbook. The publisher count the number of sentences in 150 randomly selected paragraphs. The results are shown in the table. Based on the data what is the mean number of sentences per paragraph in the textbook?
A. 4
B. 5
C. 10
D. 15
Using the weighed mean, it is found that the mean number of sentences per paragraph in the textbook is given by:
B. 5
What is the weighed mean?The weighed mean is given by the sum of all elements in a data-set multiplied by it's weight, divided by the sum of the weights.
In this problem:
The sum of the values multiplied by it's weights is: 1 x 0 + 2 x 3 + 3 x 20 + 4 x 43 + 5 x 36 + 6 x 25 + 7 x 10 + 8 x 8 + 9 x 2 + 10 x 3 = 750.Considering that there are 150 books, we have the mean is:
M = 750/150 = 5.
Hence option B is correct.

how can you find the distance between two points on a coordinate plane
Answer:
First, subtract y2 - y1 to find the vertical distance. Then, subtract x2 - x1 to find the horizontal distance. Don't worry if the subtraction yields negative numbers. The next step is to square these values, and squaring always results in a positive number. Hopefully this makes sense...

The population of a city decreases by 0.6% per year. What should we multiply the current population by to find next year's population in one step?
Answer:
0.994
Step-by-step explanation:
We should multiply the current population by 0.994.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The population of a city decreases by 0.6% per year.
Then the population after one year is given as,
P = (100% - 0.6%) of P₀
P = 99.4% of P₀
P = 0.994P₀
We should multiply the current population by 0.994.

How many solutions in the equation 3x + 5 = -2x + 5*
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
x=0
Step-by-step explanation:
Answer:
one solution (x=0)
Step-by-step explanation:
First, let's simplify the equation to 3x=-2x (we subtract 5 from both sides). Now we can add 2x to both sides to get 5x=0. There is only one solution to this (x=0).

Do you believe Ssoyoung is a bad person for doing things of her culture on camera?
this includes : cleaning animals with salt ( alive )
cooking the animals (alive but then they die )
pouring sauce on the animals ( theyre dead at this point )
and then eating the animals?
personally i see nothing wrong with it, shes korean and doesnt know the laws of america. people have shamed her into excluding the preparing of the food when its perfectly fine in her culture! :(
I dont think its fair that people from another culture are shaming her about hers.
Ssoyoung :
Answer:
She's really pretty, but if that is how she cooks I have no problem with it.
Step-by-step explanation:
I mean it is her life but that's cool that she can do that.
Also, people who are shaming her about her culture need to learn about some of the stuff their culture did because it might have been worse than that also Spicy Chicken McNuggets are awesome.
In my personal opinion, I'm kind of leaning towards both sides. Is doing something of her culture wrong? Not really. But the fact that she takes them out of the water and plays around with them is wrong. Ocean animals need air to live. It's basically torturing them.
Conclusion: Preparing and cooking along Korean culture isn't cruel. But the way she acts, torturing them for the camera, that's just wrong.

Given the two similar triangles below. What is the measure of x?
Answer:
x=2.4
Step-by-step explanation:
as the 2 triangles are similar,
[tex] \frac{6}{x} = \frac{5}{2} [/tex]
therefore ;
[tex]x = \frac{6 \times 2}{5} [/tex]
[tex]x = 2.4[/tex]
Answer:
The answer would be 2.4
Step-by-step explanation:
This is because 5 is the same as 2, and 7 is the same as y, and then 6 is the same as x. If you divide 5 by 2 you get 2.5 if you divide 6 by 2.5 you get 2.4
