A population consists of the five measurement 2,3,6,5 and 7. what is the mean?​

5× 1/2 = ? a) more than 5 because you are multiplying by a whole number b) 5/10 because you multiply the numerator and denominator by 5 c) less than 5 because you are multiplying by a number that is more than 1 d) less than 5 because you are multiplying by a number that is less than 1

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

Math each whole number with a rational,exponential expression
