Answer:
Step-by-step explanation:
Wow! There are 2 things going on here, so let's go step by step.
The first thing to notice is that the numbers are going negative, positive, negative, positive. Odd-numbered terms are negative while even-numbered terms are positive. Since 9 is odd number, we know the answer must be negative.
Secondly, the 1, 4, 9, 16 sequence is called the square numbers. They are 1 x 1, 2 x 2, 3 x 3, 4 x 4, etc. The 9th term will be 9 x 9 ( ignoring the negative).
Adding the first point with the second, we get (-81) { negative eighty-one }
Hope this helps.
Answer:
6
Step-by-step explanation:
Из 34 вы вычитаете 10, потому что это значение уже известно, осталось 24, вы делите его на 4, потому что это количество значений (или чисел), которые у вас есть, и это 6, я надеюсь, что это поможет вам с приветствием из Мексики
Answer:
The expectation and variance for the number of 1s in the sequence of die rolls is: 1/6
If the coin was unfair the change is: 1/2
The probability of obtainig heads was: 51%
Step-by-step explanation:
In probability and statistics theory:
The expectation and variance possibilities gotten rolling one dice are six.
In independent Bernoulli trials sequence with probability 1/2 of success on each trial is metaphorically called a fair coin.
By the other hand if the probability is not 1/2, it is called a biased or unfair coin.
It might be thought that the toss of a coin is always a 50/50 probability, with a 50 percent chance it lands on heads, and a 50 percent chance it lands on tails but if it starts out as heads, there's a 51% chance that it will end as heads.
Let's call the number of members x. We have x + 10 people who each pay $5, resulting in a sum of $600.
5(x+10) = 600
5x + 50 = 600
5x = 550
x = 110
1st you have to take the common denominator which is 12. to turn the 3/4 into 12 you multiply by 3 because 4×3=12
what you do to the bottom you must do to the top so 3×3=9
you are left with 6/12÷9/12
flip and multiply so 6/12×12/9= 2/3
