<u>Answer:</u>

<em>We have to determine the pattern of numbers followed in the sequence 2, 7, 8, 3, 12, 9.</em>

<em>Do a grouping of the sequence into two groups. Let the first group be 2, 7, 8 and the second group be 3, 12, 9 </em>

<em> There is a difference of 1 in the pair 2 and 3, a difference of 5 in the pair 7 and 12 and a difference of 1 in the pair 8 and 9 </em>

<em> This means there would be a difference of 5 in the next pair. </em>

<em> So, adding 5 to the first number to the third pair. </em>

<h2><em> Hence, the next number will be 13.</em></h2>

Give your opinion WHY it is BETTER to read PAPER books RATHER than online books.
Vaselesa [24]

Answer:

because you'll absorb more information. how? when reading a paperback book, you can annotate, which you cannot do with an online book. and for me personally, there's just something so magical about the smell of the glue and paper and the feeling and sound the pages make when you flip them.

good luck :)

i hope this helps

have a nice day!

I NEED HELP ASAP GIVING BRAINLIEST
Yuri [45]
If we know that 180-5=128 that means that that equation must be equal to 128.

(2^3x+1)=128

By putting 128 into exponential form with a base of 2 you get 2^7:

(2^3x+1)=2^7

Since these have the same bases we can set the exponents equal to 7. This will give us an exponent of 3x+1=7. By Subtracting across and dividing by 3 you get:

3x=6 to 3/3x = 6/2

This gives us a final answer of:

x=2

Dr. Keyes is a veterinarian who believes that people are happier if they own more pets. He hopes
pickupchik [31]

Answer:

False.

Explanation:

The study that Dr. Keyes wants to do is a study that uses two variables (pets and happiness). Dr. Keyes wishes to prove the cause and effect relationship between these two variables that prove that the greater the amount of pets (causes) people have, the greater the happiness of these people (effect). For this reason, we can say that Dr. Keyes is not doing a correlational study.

This is because, although the correlational study wishes to observe the relationship between two variables, this study cannot be applied to cause and effect relationships.
