We just have to multiply 20 by 10mm, which is 200mm. 100mm is equal to one centimeter, so the body length of the insect under the microscope is two centimeters.

In Mr. Cannon's class, 44% scored an 80 or above on the semester exam. Which of the following is NOT equivalent to 44% Question
tigry1 [53]

Answer:

11/20

Step-by-step explanation:

22/50 is equivalent because if you multiply 50 by 2 to get 100, then multiply 22 by 2, you get 44 out of 100 (44). For 11/20 if you multiply 20 by 5 to get 100, then multiply 11 by 5, you get 55 out of 100 (55). Do the same thing for all the other ones. I hope this helps! Please mark me brainliest thanks!

you sell bracelets for $2 each and necklaces for $3 each at a local flea market. You collect$95, selling a total of 37 jewelry i
Alex787 [66]
The system of linear equations that may be used in order to solve this problem is as follows:

x + y = 37
2x + 3y = 95

This is considering that x is the number of bracelets sold and y is the number of necklaces.

The values of x and y in the equation are 16 and 31, respectively.

Thus, the answer is 16 bracelets and 21 necklaces.

Which of the following correctly compares the uses of bar graphs versus pie charts? bar graphs show patterns in data with variab
saw5 [17]

Answer:

<h3><em>Bar graphs show data involved in distinct categories that do not overlap; whereas, pie charts show data as parts out of a whole (such as out of 100%).</em></h3>

Step-by-step explanation:

A bar graph, also called a bar chart, is used to present categorical variables, which involves rectangular bars with a correlation between a specific category and the frequency of them, this graphs can be also called histograms. It's used in statistics to describe a bunch a data, separating them in categories. This charts can be horizontal or vertical, and an important characteristics is that it's applied to represent discrete categories, that is, values expressed with whole numbers. (An example is attached).

On the other hand, pie charts, or circular charts, are used to indicate proportions from a whole part, like a pie or cake, you have a whole and 100% data and you divided into slices. For example, from the whole population in the U.S. we could divide it by ethnicity, parts from a whole, like show the image attached.

<h3>Therefore, based on each definition, the correct answer is:</h3>

<em>Bar graphs show data involved in distinct categories that do not overlap; whereas, pie charts show data as parts out of a whole (such as out of 100%).</em>

= (15 + 1) * 3/4

= 12th position

That number is:

= 57.4
