The mean of 10 randomly selected students is definitely more likely to be closer to 75. 10 randomly selected students to include information and are more like to reflect the class’s scores. Consider an extreme example. Seventy-five students in a class of 100 earned perfect scores. The other 25 earned zeros. The average score of the class would be 75. A sample of 10 random students would almost certainly include more 100s then 0s, but both would be included in the sample. The mean of this samples score is closer to 75 than any individuals.
Answer:
1. y^12/y^12=1
2. q^15*1/q^15=1
3. (7(123456.789)^4)^0=1
4. 2^2*1/2^5=1/2^3
5 (x^41/y^15)*(y^15/x^41)=1
Step-by-step explanation:
1. when dividing exponents, subtract the exponents. y^12/y^12=y^(12-12)=y^0=1
2. you do the same as #1
3. Any number to the power of 0 is always 1
4. 1/2^3=1/8
5. since the numerator and denominator is the same, the divide to equal 1
