Answer:
25%
Step-by-step explanation:
Since Normal Distribution is symmetrical Distribution and 5.3 and 10.7 are both 2.7 below and 2.7 above the mean respectively.
So, % of students less than 5.3 hours per week is 25%
Divide the top number by the bottom number
1/14 in 30 mins
30 mins x 14=420 mins
420 mins in hours =7 hours
Step-by-step solution:
7x + 3 + 6x + 11 = 0
7x + 6x + 11 + 3 = 0
13x + 11 + 3 = 0
13x + 14 = 0
13x = 0 - 14
13x = -14
x = -14 / 13
x = -1.077 approx.
