Answer:
her first step should be to multiply the coefficient of the first term by the constant 1 • -3 = -3
Step-by-step explanation:
i looked it up on tiger algebra lol
Answer:
11+(2+y)
Step-by-step explanation:
The associative property says that you can move numbers inside the parentheses around if all the numbers are the same operation in a simple sense
So that means in this case: 2+(11+y)
We can switch the 2 and the 11 around since they are both the same, addition.
11+(2+y)
Answer:
10th term of the sequence = 0.537
Step-by-step explanation:
First three terms of the sequence are → 5, 4,
..........
Ratio of 2nd and 1st term of the sequence = 
Ratio of 3rd and 2nd term of the sequence = 
= 
Therefore, ratio between every successive term to the previous term is common.
Common ratio 'r' = 
First term of the sequence 'a' = 5
nth term of a geometric sequence = 
Therefore, nth term of the given term will be 
Now we have to find the 10 term of the given sequence.
For n = 10,

= 0.53687
≈ 0.537
Therefore, 10th term of the sequence is 0.537
The binomial distribution is given by,
P(X=x) =

q = probability of failure = 1-0.2 = 0.8
n = 100
They have asked to find the probability <span>of obtaining a score less than or equal to 12.
</span>∴ P(X≤12) =

where, x = 0,1,2,3,4,5,6,7,8,9,10,11,12
∴ P(X≤12) =

+

Evaluating each term and adding them you will get,
P(X≤12) = 0.02532833572
This is the required probability.
