Answer:
£2,121.80
Step-by-step explanation:
To solve this problem, we can use the compound interest formula:
<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 3% into a decimal:
3% -> 
-> 0.03
Now, plug in the values:
Your answer is £2,121.80
Answer:
129
Step-by-step explanation:
Considering the survey to be representative, you can simply multiply the share of students <em>p</em> preferring “Track & Field” with the whole school population at the same time to estimate the number of such students in the whole school.
First we need to find the relative share <em>p</em> of such answers in the study by dividing it by the sum of answers, assuming that the table is complete for that random sample:
<em>p</em> = 4/(8 + 5 + 4) = 4/17
Then for the whole school we get 550 <em>p</em> ≈ 129.4
Answer:
A. H(x) is an inverse of F(x)
Step-by-step explanation:
The given functions are:
We compose F(x) and G(x) to get:
Hence G(x) is not an inverse of F(x).
We now compose H(x) and G(x).
We simplify to get:
Since , H(x) is an inverse of F(x)
