2+12a. When adding, you're only collecting "like terms".

Let's check the dot product .

v.w = 5(4)-2(10) = 20 -20 =0

So the dot product is not 20 . And since the dot product is zero, so they are perpendicular.

And the y component of w is 10.

So correct options are first and third .

The histogram shows the duration, in minutes, of movies in theaters.
neonofarm [45]

The <em>correct answer</em> is:

The median is less than the mean.

Explanation:

This histogram is skewed right; the data "peaks" further to the left than the center.

If a histogram is skewed right, the mean is greater than the median.

This is because skewed-right data have a few large values that increase the mean but do not affect where the exact middle of the data is.

Elis [28]
For 0 minutes, it would be 0 minutes (obviously)
for 1 minute, it would be 3
for 2 minutes, it would be 6 pages
and finally, 3 minutes, will be 9.
to get the answers, you would just have to add 3, since every minute, nick reads 3 pages.

Plzz help!!!!!!!<br>I 'll give brain liest​
Basile [38]

Answer:

Step-by-step explanation:

1. 3x2 + 5x - 4 + 6x2 - x + 7

= combining like terms

= 9x2 + 4x + 3

2. 2y2 - 3y + 6 + y2 - 5y - 1 + (-4) + 2y2 - 2y

= 5y2 - 10y + 1

3. 2x2y - 3xy2 + x2y - 4x2y - 2xy2

= - x2y - 5xy2

4. x2 - y2 + 2x2 - 3xy + 4y2 + 3y2 - 5xy - x2

= 2x2 - 8xy + 6y2
