Answer:
A and E
Step-by-step explanation:
9^3 / 9^3
Same number on top and bottom so 1 is an answer
look at the exponents, when dividing with exponents, you just subtract them, so it could also be 9^0, which is also 1
Sequence will look like this:
Term 1: 20 --------- 20 + 5(0)
Term 2: 25 --------- 20 + 5(1)
Term 3: 30 --------- 20 + 5(2)
Term 4: 35 --------- 25 + 5(3)
ETC.
It cab noted that the numbers in the bracket (that is, 0, 1, 2, 3, 3, etc) = n-1
Then, the explicit formula will be;
an = 20 + 5(n-1).
The correct answer is D.
Answer:
£84
Step-by-step explanation:
The given ratios are ...
A : N = 2 : 1
N : J = 3 : 1
Putting these together, we have ...
A : N : J = 6 : 3 : 1
There are a total of 6+3+1 = 10 ratio units, so each is worth £140/10 = £14.
Angad's share is 6×£14 = £84.
_____
<em>Check</em>
Nick gets £42, and June gets £14. Together, they share £84 +42 +14 = £140.
Answer:
The smallest sample size to satisfy the conditions is n=500.
Step-by-step explanation:
The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:
The largest sample size required will be for the minimum p or (1-p).
This happens to be the proportion that can play other instruments: 2%.
Then, we can calculate the minimum sample size as:
