Answer:
80pi-60pi
Step-by-step explanation:
To find how much Juan ran, we must find the circumference.
pi *30*2=60*pi (which is how much Juan ran.)
pi*40*2=80*pi (which is how much Miguel ran)
80pi-60pi would be how much farther Miguel ran than Juan.
Answer:
c=f(x)−ax^2−bx
Step-by-step explanation:
To find this out we have to add 5 tens and 13 ones.
5 tens is equal to
10 + 10 + 10 + 10 + 10 = 50
And 13 ones is equal to
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 13
Now add 50 and 13
50 + 13 = 63
So your answer is 63
good Luck! :)
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
