Answer:

<h2>7y² - 6y -17</h2>

Step-by-step explanation:

(-2y^2-11y-7)-(-9y^2-5y+10)  (firstly, we remove the brackets)

-2y^2 - 11y - 7 + 9y^2 + 5y - 10

= (-2y^2 + 9y^2) + (-11y + 5y) + (-7 - 10)

=  (7y²)                  + (-6y)         + (-17)

Type an equation for the following pattern
umka2103 [35]

For the given table, the difference between two consecutive y terms are

4-3=5-4=6-5=7-6=1

It means the difference is constant. So the given function is in arithmetic progression.

And to find the equation, representing the given series, we will use the formula for the nth term of arithmetic series, which is

a_{n}= a+ (n-1)d

Here,

a_{n} =y, n=x, and \ d  \ for \  the \  common \ difference.

So we will get

y= 3+(x-1)(1)&#10;\\&#10;y = 3 + x-1&#10;\\&#10;y= x +2

Goshia [24]

"The graph shows the distribution of time (in hours) that teenagers spend playing video games per week. ", The statement that best describes the distribution is  "The distribution is approximately Normal, with a mean of 14 hours and a standard deviation of 4" Option B.

This is further explained below.

<h3>What is Normal distribution?</h3>

Generally, Data closer to the mean tends to occur more often than data further from the mean, as shown by the normal distribution, also known as the Gaussian distribution. The normal distribution may be represented graphically as a "bell curve."

In conclusion, "the graph illustrates the distribution of the amount of time, in hours, that teens spend playing video games over the course of a week," The statement "The distribution is nearly normal, with a mean of 14 hours and a standard deviation of 4" is the one that gives the most accurate account of how the data was distributed.
