Answer: Yes, your friend is correct

Additional Note: Associative Property is modifying the addendum grouping does not alter the number.

Answer: The friend is wrong.

Step-by-step explanation:

In this equation, they are doing the commutative property. Commutative property is a property that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The Associative Property of Addition is a property which means that rearranging the parentheses in an expression will not change the result. Clearly, they didn’t do that; they just switched the 7 and x around which is the commutative property.

This might be slightly confusing but I hope this helps :’)

The dot plots show rainfall total for several spring storms in highlands areas an lowlands areas what is the median rainfall for
tankabanditka [31]

*See attached picture showing the dot plots referred to

Answer:

16mm

Step-by-step Explanation:

Given the dot plot showing rainfall for Highlands storms, we can find out the median rainfall for Highlands storms by mere observing the dot plot and locating where the middle value falls within the data set that is represented on the dot plot.

Thus, we have 44 data sets that is being represented on the plot, with one dot representing one data set for rainfall. This means, since the total number of data set is even, our median lies between the 22nd and the 23rd dot or data set that is being plotted.

From the dot plot for Highlands, the 22nd and 23rd dots are 16 and 16 respectively.

Therefore, median rainfall for Highland storms = (16 + 16) ÷ 2 = 16.

Can someone pls give me the angles using the tangent^-1
Brut [27]

9514 1404 393

Answer:

  ∠U = 60°

  ∠W = 30°

Step-by-step explanation:

The side length ratios are ...

  1 : √3 : 2

so you know this is one of the "special triangles." Its angle measures are 30°, 60°, and 90°. The smallest angle (W) is opposite the shortest side (7).

The angle measures are ...

  m∠U = 60°

  m∠W = 30°

[the UW measure is correct]

_____

<em>Additional comment</em>

Your calculator can tell you the arctangent of √3 or 1/√3. Be sure to set it to degrees mode.
