Answer:
153 cm²
Step-by-step explanation:
The area is given by the formula ...
A = (1/2)bh
where b is the base length, and h is the height measured perpendicular to the base.
The diagram shows b = QR = 18 cm, and h = 17 cm. So, the area is ...
A = (1/2)(18 cm)(17 cm)
A = 153 cm²
Complete Question
Although the first quarter of 2002 was quite dismal on Wall Street, mutual funds investing in gold companies rose an average of 35.2%. Assume that the distribution of returns in the first quarter of 2002 for mutual funds specializing in gold companies is fairly symmetrical with a mean of 35.2% and a standard deviation of 20%. If random samples of 16 gold stock funds were selected:
90% of the sample mean returns are between what two values symmetrically distributed around the mean?
Answer:
The two values symmetrically distributed around the mean are
21.87\% and 43.17\%
Step-by-step explanation:
From the question we are told that
The sample size is
The sample mean is
The standard deviation is
Generally the degree of freedom is mathematically represented as
=>
=>
From the question we are told the confidence level is 90% , hence the level of significance is
=>
Generally from the t distribution table the critical value of at a degree of freedom of is
Generally the margin of error is mathematically represented as
=>
=>
Generally 90% confidence interval is mathematically represented as
=>
converting to percentage
=>
Hence the 90% of the sample mean returns are between 21.87\% and 43.17\%
Answer:
ok but I know this is a lie I'm just willing to help
1. The data is not linear. There's not a constant difference between the f(x) values. (AKA there's not a fixed slope between the data points)
2. The data is exponential, because there's a consistent ratio in the f(x) values:
189/567 = 1/3
63/189 = 1/3
21/63 = 1/3
7/21 = 1/3
Each new y-value (aka f(x)-value) is 1/3 the previous value.
Also, f(0)=567.
If we put that together, we have f(x) = 567 (1/3)^x.
