Explain how you would graph: n ≥ -8
vodomira [7]

Answer:

(attached file #2)

Step-by-step explanation:

let's change the variable n to a variable x (it can be x and y):

x ≥ -8

go to the X-axis which is the line going horizontal, just as the first picture attached!

2. Now go to the -8 on that line and draw a straight bold line going up (vertical)

and there you have the answer to the question.

if the question was with this symbol: < or > then the line would be dashed instead of being a bold solid straight line!

Hope this helps,

Lucas

A flower bed contains 52 roses and 48 tulips. Two flowers have wilted, what is the probability that the flower is a tulip.
Sergio [31]
First, I add 52 to 48 to get the total amount of flowers.  52 + 48 = 100.  Out of those 100, there are 48 tulips.  If one flower wilted, the probability of it being a tulip would be 48/100, or 0.48.  If a second flower wilted (with only 99 flowers left, and only 47 tulips left), the probability of it being a tulip is 47/99 or 0.474747...  To get the probability of both of those being tulips, multiply the two together.  48/100 * 47/99 = 2256/9900 (then, simplify to 376/1650)

I hope this helps! Can I have Brainliest? :)

Express the terms of the following sequence by giving a recursive formula.
emmasim [6.3K]

The recursive formula for given sequence is: a_n = a_{n-1}-7

And the terms will be expressed as:

a_1 = 11\\a_2 = a_{2-1} - 7 \\a_2= a_1 - 7\\a_2 = 11- 7\\a_2 = 4\\a_3 = a_{3-1} - 7 \\a_3= a_2 - 7\\a_3 = 4 - 7\\a_3 = -3\\a_4 = a_{4-1} - 7 \\a_4= a_3 - 7\\ a_4= -3 - 7\\a_4 = -10\\a_5 = a_{5-1} - 7 \\a_5= a_4 - 7\\a_5 = -10 - 7\\a_5 = -17\\

Step-by-step explanation:

First of all, we have to determine if the given sequence  is arithmetic sequence or geometric. For that purpose, we calculate the common difference and common ratio

Given sequence is:

11,4,-3,-10,-17...

Here

a_1 = 11\\a_2 = 4\\a_3 = -3\\So,\\d = a_2 - a_1 = 4-11 = -7\\d = a_3-a_2 = -3-4 = -7

As the common difference is same, given sequence is an arithmetic sequence.

A recursive formula is a formula that is used to generate the next term of the sequence using the previous term and common difference

So, the recursive formula for an arithmetic sequence is given by:

a_n = a_{n-1} +d\\Putting\ d = -7\\a_n = a_{n-1}-7

Hence,

The recursive formula for given sequence is: a_n = a_{n-1}-7

And the terms will be expressed as:

a_1 = 11\\a_2 = a_{2-1} - 7 \\a_2= a_1 - 7\\a_2 = 11- 7\\a_2 = 4\\a_3 = a_{3-1} - 7 \\a_3= a_2 - 7\\a_3 = 4 - 7\\a_3 = -3\\a_4 = a_{4-1} - 7 \\a_4= a_3 - 7\\ a_4= -3 - 7\\a_4 = -10\\a_5 = a_{5-1} - 7 \\a_5= a_4 - 7\\a_5 = -10 - 7\\a_5 = -17\\
