Answer:

So the possible answer would be 59%

Step-by-step explanation:

A study estimated that 64% of the residents of a town (with an error range of +-12 percentage points at 95% confidence)  

In this question study gives a range 64 + or -12 it means they are not sure about answer but they estimated answer choice between 52 to 76

(64 - 12= 52 to 64 + 12 = 76).

I would figure out the lowest estimate and the highest estimate. and the answer would be between the two numbers.

In the choices there is only one number between 52 and 76. So the possible answer would be 59%.

What's the difference between adding two rational number and get a negative number
nikklg [1K]

Comparing two rational numbers

Use fraction form:

 

Make the denominators the same and compare the numerators. The number with the smaller numerator is smaller. For example, to compare a/b and c/d, we rewrite

 

a/b=a*d/b*d

  = ad/bd and c/d = c*b/d*b=bc/bd

 

Now just compare the numerators : "ad" and "bc"

 

Multiplying and Dividing Rational Numbers 

 

Multiplying and dividing rational numbers in decimal form is the same as multiplying and dividing integers. The decimal place of the product is the same of all decimals of all multiplied numbers. For example, 3.12*2.4.

 

Solution => 3.12*2.4=7.488

 

When multiplying or dividing rational numbers in fractional form, you multiply the numerators (N*N) and then multiply the denominators (D*D).

 

When dividing rational numbers in fractional form, first take the reciprocal of the divisor, and then multiply the numerators and the denominators.

 

Example => 5/9 divided by 2/7 .

 

Solution => 5/9 * 7/2 =  35/18

 

 

Adding Rational numbers

 

Adding and Subtracting rational numbers in decimal form is the same as adding and subtracting integers.

 

Example => -3.54+2.79=-0.75

 

When adding or subtracting rational numbers in fractional form, first make the denominator equal, and then add or subtract the numerators.
