A set of data has a normal distribution with a mean of 5.1 and a standard deviation of 0.9.

What percent of data lies between 6.0 and 6.9?

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
