Answer:
0.45 part of the banner is painted orange
Step-by-step explanation:
portion of rectangular banner painted green = 0.75
Portion of green painted part which is now painted orange = 0.60
Hence we can say that
0.6 part out of 0.75 part of total banner is painted orange
mathematically it is
0.6 * 0.75 = 0.45
Thus 0.45 part of banner is painted orange .
Answer:
f(0,0)=ln19
Step-by-step explanation:
is given as continuous function, so there exist 
and it is equal to f(0,0).
Put x=rcosA annd y=rsinA
we know that 
, so we have that
So f(0,0)=ln19.
Answer: (80% , 85%)
Step-by-step explanation:
We know that, confidence interval for population proportion is given by :-
(p-E , p+E)
, where p = sample proportion , E = Margin of error.
Given : Proportion of elementary school teachers who are female = 82%.
The article also states the maximum error of their estimate = 3%.
Then, the 90% confidence interval for the proportion of elementary school teachers who are female will be :
(82%-2% , 82%+3%)
= (80% , 85%)
Hence, the resulting 90% confidence interval for the proportion of elementary school teachers who are female = (80% , 85%)
