Big/small=4/7
r1/r2=4/7 where r1, r2 are radius of a big and small circles respectively
r1/3=4/7
r1=12/7
circumference of a big circle is2πr1=2π*12/7=24π/7 cm
Answer: D
Step-by-step explanation:
Analyzing the given values and the given equation, we have the following:
A = $25,000
r = 0.11
t = 6
The equation has the form:
y = A (1-r)^t
Plugging in the given values into the equation,
y = $25,000 (1 - 0.11)^6
y = $25,000 (0.89)^6
Therefore, the answer is
A. y=25,000(.89)^6
Answer: 1.2703
Step-by-step explanation:
Given : Sample size : n= 17, which is a small sample (n<30), so we use t-test.
Significance level : 
Then , Critical value : 
Standard deviation: 
The formula to find the margin of error : -
Hence, the error bound (EBM) of the confidence interval with a 90% confidence level.=1.2703
