I don't think there's any answer. It says that the absolute value of x-7 is negative 2, but an absolute value is always positive. So there's no value for x that can make the equation a true statement.
The lowest common multiple of 3, 5, and 7 is 105, so
that's the smallest number that has those prime factors.
Every multiple of 105 is another one:
210, 315, 420, etc.
So is (105) times (any multiple of 3 or 5 or 7):
(x 3, 6, 9) 315, 630, 945, etc.
(x 5, 10, 15) 525, 1050, 1575, etc.
(x 7, 14, 21) 735, 1470, 2205, etc.

Answer:
2.7 and 99.6%
Step-by-step explanation:
In this question, we are asked to calculate the percentage of the population scores as a genius.
We proceed as follows;
z =( Mean - value)/standard deviation= (140 - 100)/15 = 2.6667 = 2.7
From normal probability table, given that z = 2.67, the probability is 0.9962
This means that the required percentage is 99.6%
