First you add 11+4 which equals 15 then you add 15+9 which equals 24. So Sandra sees 24 flags
Answer:
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean 
and standard deviation 
In this problem, we have that:
So
<span>cos (X) + sin (X) = 0
Subtract cos(x) from each side:
sin(x) = -cos(x)
Divide each side by cos(x) :
sin(x) / cos(x) = -1
But sin/cos = tangent
<em>tan(x) = -1</em>
x = 135° and 315°
x = 3/4 pi radians and 7/4 pi radians

First you will need a piece of paper, well not really. All this problem is involving is 740
+ 710
=1,500 meters
Answer:
1. 3) measure of angle 3 and measure of angle 5 are supplementary
2. x=16
