I think Alexa would be since .3 is a larger number than .03
This question mean no sense lol
This problem is solely on right triangles, wherein the Pythagorean theorem may be applied. We must first find the angle of elevation of the flagpole using Tim's height and the difference between the shadow of the flagpole and Tim's distance from the flagpole. Therefore tan a = 1.65/(16.6-12.5) where a=21.68 degrees. We use this angle to determine the height of the flagpole. tan 21.68 = x/ 16.6 where x=height of flagpole=6.6 meters.
Answer:
b)
Step-by-step explanation:
a) 4+12>8
12+8>4
4+8=12
NO
b) 5+12>10
10+5>12
12+10>5
YES
c) 16+4>6
6+4<16
NO
d) 30+12>6
12+6<30
NO
Answer:
The need to sample 76 days.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so
Now, find the margin of error M as such
In which
is the standard deviation of the population and n is the size of the sample.
How many days do they need to sample
We need to sample n days.
n is found when M = 300.
We have that 
So




Rounding up
The need to sample 76 days.
