René Descartes provided the first systematic link between Euclidean geometry and algebra.
<h3>What is Geometry?</h3>
This branch of mathematics involves the study of object shape, their spatial relationship and that of their surrounding space.
René Descartes is referred to as the father of analytic geometry due to him establishing the relationship between Euclidean geometry and algebra.

D . 3(5+7) that is the expression which is equivalent
Answer:
The 99% confidence interval for the fraction of US adult Twitter users who get some news on Twitter is (0.4872, 0.6018). It means that we are 99% sure that the true proportion of US adult Twitter users who get some news on Twitter is between 0.4872 and 0.6018.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
, and s is the standard error.
54% of US adult Twitter users get at least some news on Twitter.
This means that 
The standard error for this estimate was 2.4%
This means that 
99% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
The lower bound is:
The upper bound is:
The 99% confidence interval for the fraction of US adult Twitter users who get some news on Twitter is (0.4872, 0.6018). It means that we are 99% sure that the true proportion of US adult Twitter users who get some news on Twitter is between 0.4872 and 0.6018.
Answer:
3/25
Step-by-step explanation:
3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles
P(green) = number of green / total = 4/10 = 2/5
We replace it
3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles
P(red) = number of red / total = 3/10
P(green, replace,red) =2/5*3/10 = 3/25
Answer:
150
Step-by-step explanation:
The overall answer should equal 360. 90+90+30=210. That leaves us with x. Try subtracting 360-210=x. :) Hope this helps!
