Answer:

1595

Step-by-step explanation:

The given sequence is

2, 7, 26, 101, 400, ?

We need to find the missing term in this pattern.

First term is 2.

a_2=2\times 4-1=8-1=7

a_3=7\times 4-2=28-2=26

a_4=26\times 4-3=104-3=101

a_5=101\times 4-4=404-4=400

So, the nh term of the sequence is

a_n=a_(n-1)\times 4-(n-1)

Substitute n=6,

a_n=a_(6-1)\times 4-(6-1)

a_n=a_(5)\times 4-5

To find the next term, we need to find the product of 400 and 4 and after that the difference of resultant number and 5.

a_6=400\times 4-5=1600-5=1595.

Therefore, the missing term is 1595.

-3+3x=-2(x+1)<br> the 2 is a negative<br> please break it down
Veronika [31]
-3+3x=-2(x+1) First: I will get rid of the bracket:


-3+3x=-2x-2

Now, all the x goes to the left side, all the numbers without x to the right side:


3x+2x=-2+3

we add up"

5x=1

divide by 5:

x= \frac{1}{5}

I’m having a hard time with this. Is this a typo by the teacher or should I actually be looking for a size?
Lemur [1.5K]

Step-by-step explanation:

There are 12 games in the population.  You need to use a random number generator to choose 2 of these games.

RandomSample[{1,2,3,4,5,6,7,8,9,10,11,12},2]

Let's say the first sample you get is {1,5}.  That corresponds to game times of 8 minutes and 7 minutes.  The mean game time for that sample is 7.5 minutes.  So the first row in your table would be:

\left[\begin{array}{ccc}Sample&List\ of\ Game\ Times&Mean\ Game\ Time\\1&8,7&7.5\end{array}\right]

Complete the equation of the line through (-9 -9) and (-6 0)
Katena32 [7]

Answer:

y = 3x + 18

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 9, - 9) and (x₂, y₂ ) = (- 6, 0)

m = \frac{0+9}{-6+9} = \frac{9}{3} = 3, thus

y = 3x + c ← is the partial equation of the line

To find c substitute either of the 2 points into the partial equation

Using (- 6, 0), then

0 = - 18 + c ⇒ c = 0 + 18 = 18

y = 3x + 18 ← equation of line
