Answer:

x = 18

Step-by-step explanation:

The product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord, that is

21x = 14 × 27 = 378 ( divide both sides by 21 )

x = 18

Ok so I have math homework and I need so help ASAP I need to find the average of 35 40 12 16 25 and 10 so could someone plz plz
sleet_krkn [62]

Answer: 23! Add your numbers, and divide that sum by the amount of numbers added to get average!

Step-by-step explanation:

The average is found by adding all numbers of the sample, and diving by the amount of numbers added. For example:

The average of 1, 2, and 3. You first add 1 + 2 + 3 to get 6.

You then divide 6 by the number of numbers added, being 3 (1, 2, and 3.).

6 / 3 = 2. The average of 1, 2, and 3 is 2.

In your case, you have 35, 40, 12, 16, 25, and 10.

First you add 35 + 40 + 12 + 16 + 25 + 10 to get 138.

Then you divide 138 by the amount of numbers you added: 6.

138 divided by 6 = 23 (138/6).

Hope this helps!

Add your numbers, and divide that sum by the amount of numbers added to get average!

What ones are functions and which are not pls help
Fantom [35]
Functions: the chart with number values, the dot graph, and the middle graph on the right

Not functions: the top graph on the left with the vertical line, the graph with the circle, and the bottom right graph

Any graph that doesn’t pass the vertical line test is not a function. You can do this by starting at the top of the graph and drawing a line straight down through what you are testing. If you pass through the line or circle more than once it is not a function.
If you look at the number values if the x value repeats more than once it is not a function.
