Answer:
k = 10
Step-by-step explanation:
The sum of k terms of a geometric sequence with first term a1 and common ratio r is given by ...
... Sk = a1·(1 -r^k)/(1 -r)
For the given numbers, this is ...
... 118096 = 78732·(1 -(1/3)^k)/(1 -1/3)
Manipulating this to get the term containing k, we have
... 1 -(2/3)(118096/78732) = (1/3)^k
... 1/59049 = (1/3)^k
Taking logarithms, we get
... -log(59049) = -k·log(3)
... log(59049)/log(3) = k = 10
The answer would be 6 the easy way is to divide 48 by 8
<u>In sentence 7, the </u><u>phrase</u><u> by all accounts is best replaced by </u><u>however.</u>
Correct option is A
- The sentence that precedes 7 states something that is in contrast with it.
- Therefore 'by all accounts' in sentence should be changed to 'however' as it is generally used to present something that is different from or contrasts with the previous statement.
- Thus A is the best answer. The other options are incorrect because they do not convey the contrast that is required in the given context.
What is a phrase in grammar?
- In syntax and grammar, a phrase is a group of words which act together as a grammatical unit.
- For instance, the English expression "the very happy squirrel" is a noun phrase which contains the adjective phrase "very happy".
- Phrases can consist of a single word or a complete sentence.

X 1 2 3 4
p(x) 0.40 0.20 0.15 ?
If the items are only 4. The total of the probability must be 1 or 100%
1 - 0.40 - 0.20 - 0.15 = 0.25
The probability of 4 is 0.25.
10*0.2=2
HOPE THIS IS RIGHT!!!!!!!!!!
