Answer:
For this case from the info given we have the estimated proportion of people who thinks that Children of illegal inmigrants should be able to attend public school
So then the value reported 45% or in fraction 0.45 represent the sample proportion fo interest.
And this value was calculated with a sample of n =1000 people.
And X for this case is 450, because 0.45*1000=450
The real interest is on the population proportion 
of people who thinks that Children of illegal inmigrants should be able to attend public school
Step-by-step explanation:
Assuming the following question : "Give the relevant proportion using correct notation. Your answer should be an expression composed of symbols: A recent headline states that 45% Think Children of illegal inmigrants Should Be Able to Attend Public School. The report gives the results of a survey of 1000 randomly selected likely voters in the US."
For this case from the info given we have the estimated proportion of people who thinks that Children of illegal inmigrants should be able to attend public school
So then the value reported 45% or in fraction 0.45 represent the sample proportion fo interest.
And this value was calculated with a sample of n =1000 people.
And X for this case is 450, because 0.45*1000=450
The real interest is on the population proportion of people who thinks that Children of illegal inmigrants should be able to attend public school
We need to perform multiplication and addition property for this problem to represent the final result in decimal form. So, the expression is,
9x100+2x10+3x0.1+7x0.001 .
Now 9 x 100= 900
2 x= 10= 20
3x0.1= 0.3
7x 0.001=0.007
Now we can all the numbers. Hence,
900+20+0.3+0.007=920.307
So, the decimal number is 930.307.
Answer:
He should invest $31,000 in tax-free to get a return of $4,790
Step-by-step explanation:
Let the amount he will invest in tax-free be $x while the amount in money market be $y
Adding both we have the total;
x + y = 60,000 ••••••••(i)
Then let’s work with the percentages;
7.5% of x + 8.5% of y = 4,790
7.5/100 * x + 8.5/100 * y = 4,790
7.5x/100 + 8.5y/100 = 4790
multiply through by 100
7.5x + 8.5y = 479000 ••••••(ii)
From i, y = 60,000 - x
Put this into ii
7.5x + 8.5(60,000-x) = 479000
7.5x + 510,000 -8.5x = 479000
8.5x - 7.5x = 510,000 - 479,000
x = $31,000
