Answer:
Now we can estimate the population variance with the sample variance given by:
And replacing we got:
And the estimator for the population deviation 
is given by :
Step-by-step explanation:
For this case we have the following data given:
1.83,1.85,1.79,1.73,1.69,1.74,1.76,1.70
First we need to calculate the mean with the following formula:
And replacing we got:
Now we can estimate the population variance with the sample variance given by:
And replacing we got:
And the estimator for the population deviation is given by :
Answer:
25
Step-by-step explanation:
165-140=25
140-115=25
115-90=25
90-65=25
65-40=25
You are correct!
90 would be the correct choice, here is why:
use the eqation: $20*30*15%
first times $20*30=600
now, 600 *15%= $90
therefore, your answer is 90 dollars
Answer:
yes

Answer:760ft2
Step-by-step explanation:
Area of first triangle = 1/2bh = 1/2*8*15=60ft2
Area of second triangle = 60ft2
Area of bottom rectangle =20*15=300ft2
Area of top rectangle = 17*20=340 ft2
Total surface area =60+60+300+340
=760ft2
