Answer:

∠T = 60

∠V = 30

Step-by-step explanation:

All angles in a triangle must add up to 180, we can tell one angle is 90 degrees because it has the right angle square mark on it. The other two angles are 2x and x so:

90 + x + 2x = 180

Step 1 - Subtract 90 from both sides of the equation:

90 + x + 2x - 90 = 180 - 90

x + 2x = 90

3x = 90

Step 2 - Divide both sides by 3 to find x:

\frac{3x}{3} = \frac{90}{3}

x  = 30

Step 3 - Now calculate the sizes of each angle:

∠T is 2x so:

2 x 30 = 60

∠V is x so:

V = 30

In conclusion:

∠T = 60

∠V = 30

Hope this helps!

For which data representation is the median the better measure of center
arlik [135]
Answer: The second graph

In all but the 3 graphs, the data is perfectly symmetrical. This means that the mean and the median would be the same.

However, in the second graph the data is skewed to the right. This means that the mean would also be skewed to the right due to the larger scores there. Using the median in this case would give a clearer picture of the data.

Drag each expression to show whether it is equivalent to −2.6−(−5.9) -2.6 x - -5.9 x , −2.6+(−5.9) -2.6 x + -5.9 x , or neither.
vredina [299]

Answer:

-2.6x-(-5.9x) is equivalent to -2.6x+5.9x and 5.9x+(-2.6x)

-2.6x+(-5.9x) is equivalent to -2.6x-5.9x and -5.9x+(-2.6x).

The expressions which are equivalent to neither:

-5.9x+2.6x and 5.9x-(-2.6x)

Step-by-step explanation:

Given the expressions:

1) -2.6x-(-5.9x)

2) -2.6x+(-5.9x)

To find:

The expressions equivalent to the given expressions.

or the expressions which are not equivalent to any of the given expressions.

Solution:

First of all, let us solve the brackets from the given expressions.

-2.6x-(-5.9x) can be written as -2.6x+5.9x (because when we multiply a negative sign with negative, it becomes positive.)

Similarly -2.6x+(-5.9x) can be written as -2.6x-5.9x (because when we multiply a positive sign with negative, it becomes negative.)

Therefore, the answer is:

-2.6x-(-5.9x) is equivalent to -2.6x+5.9x and 5.9x+(-2.6x)

-2.6x+(-5.9x) is equivalent to -2.6x-5.9x and -5.9x+(-2.6x).

The expressions which are equivalent to neither:

-5.9x+2.6x and 5.9x-(-2.6x)
