I am assuming 33 is B^(2/3) times B^(1/2)
See the following image
Answer:
39
Step-by-step explanation:
Just add
Answer:
56+12=68. 68 inches
Step-by-step explanation:
julie‘s shadow is 12 inches taller than Nicole’ so you would just add 12 to 56.
So, here we have an exponential function.
Remember that an exponential function has the form:

Where a represents an initial amount, and r is the rate of this amount to change. (Increase, or decrease).
So, given that the population of City A in 2000 was 40 thousand people and the population increased by 13% each year, we can say that

So,

For city B:

But something different happens with city C. This is not an exponential function, this is a linear function.
So,

Answer:
a
The 95% confidence interval is 
b
Yes there is statistically significant evidence that students in Florida perform differently from other students in the United States
Step-by-step explanation:
From the question we are told that
The population mean is 
The sample size is 
The sample mean is 
The standard deviation is 
Given that the confidence level is 95% then the level of significance is mathematically represented as

=> 
=> 
The critical value for
obtained from the normal distribution table is

Generally the margin of error is mathematically represented as

=> 
=> 
Generally the 95% confidence interval is mathematically represented as

=> 
=> 
Given that the population mean(1000) is not within the 95% confidence interval for l for the average test score for students in Florida, then it means that there is statistically significant evidence that students in Florida perform differently from other students in the United States
