Answer: 900
Step-by-step explanation:
12% means 0.12
total amount means X
"of" means multiply
"is" means equal sign
0.12 * X = 108 / Divide both sides by 0.12
X = 108 / 0.12 = 900
The estimate of the population proportion of defectives is 0.05.
Given that,
There are 10 different samples of 50 observations, that is, total of 500 observations.
To find : The estimate of the population proportion of defectives
And total number of defectives from 500 observations is (5+1+1+2+3+3+1+4+2+3) = 25
Thus, the point estimate for the population proportion defectives will be,
=25/500=0.05
or just obtain the individual proportion of each sample and then take their average to obtain the same result.
Thus, the point estimate for the population proportion defectives will be 0.05

Answer:
TSA of ice cream cone = 330 cm^2
Step-by-step explanation:
Total Surface Area of ice cream cone = pie r( r+h )
22/7 * 7 (7+8)
22 ( 7+8)
22*15
= 330 cm. square
