Your answer would be 600 because 696-600=96
Answer:
It is a growth rate of 86%.
Step-by-step explanation:
Hi, to answer this question we have to analyze the exponential function:
A = P (1 + r) t
Where:
p = original population
r = change rate (decimal form)
t= time (x)
A = population after t years
Replacing with the values given:
y = 270(1.86)^x
Since the term 1.86 is equal to 1+ 0.86, it is a exponential growth because the rate is positive. (r =0.86)
In percentage form: 0.86 x 100 =86%

The student will have $135 in her bank account at the end of the ninth week. You can fine this out by finding out the amount she deposits a week and to do this you would take the $30 and divide it by 2 because she had $30 at the end of the second week.
30/2=15
So you see that the student deposits $15 each week, so to find out how much money she will have in 9 weeks you will multiply her $15 by 9.
15x9=135
So the student will have $135 at the end of the ninth week.

Answer:
The 95% confidence interval is
This interval means that there 95% confidence that the true mean is within this interval
Yes i would agree with my friend because the lower and the upper limit 95% confidence interval for mean points scored at home is greater than 98 points
Step-by-step explanation:
From the question we are told that
The sample size is n = 20
The sample mean is
The standard deviation is
Given that the confidence level is 95% then the level of significance is mathematically evaluated as
Next we obtain the critical value of from the normal distribution table, the value is
Generally the margin of error is mathematically represented as
substituting values
The 95% confidence interval is mathematically represented as
substituting values
