Jose works 25 hours a week at $12.50 per hour. How many weeks will he have to work to earn $3,437.50?
Sidana [21]
The answer is 11. You multiply 25 and 12.5 first. then once you find out how much money you get each week, you divide the 3437.5 by the number you got, which is 312.5. Divide 3437.5 by 312.5

The ages of undergraduate students in a state
Elan Coil [88]

The percent of students that are aged 19 years or more is determined as 84%.

<h3>One standard deviation below the mean</h3>

In a normal distribution curve 1 standard deviation below the mean is defined as follows;

  • 1 std below mean : M - d = 16%

M - d = 20.6 yrs - 1.3 yrs = 19.3 years ≈ 19 years

19 years or more will occur at (M - d) + (M) + (M + 2d) = 100% - (M - d)

                                                                                       = 100% - 16%

                                                                                       = 84%

Thus, the percent of students that are aged 19 years or more is determined as 84%.
