By def. of the derivative, we have for y = ln(x),
Substitute y = h/x, so that as h approaches 0, so does y. We then rewrite the limit as
Recall that the constant e is defined by the limit,
Then in our limit, we end up with
In Mathematica, use
D[Log[x], x]
30% you have to find a equivalent number with the denominated 100z multiply both numerator and denominator by 100. 120/400x100/100= (120 x 100/400) x 1/ 100=30
50% of people get scores from 0 to 100 on the Stanford-Binet and Wechsler IQ tests.
Both Stanford -Binet and Wechsler IQ tests are being used to calculate IQ of people. Stanford- Binet calculates IQ by measuring Verbal and Non Verbal skills. Wechsler calculates IQ by measuring Verbal and performance scales. The principle to measure IQ is (Mental age/ Chronicle Age)100. If IQ of a person is more than 130 then he is considered a Gifted person. If IQ of a person is less than are equals to 110 then he is considered an Average IQ person.
According to archive information On the Stanford-Binet and Wechsler IQ tests 50% of people get scores from 0 to 100.

Answer:
49 stones
Step-by-step explanation:
Write the following proportion based on the given ratio of marbles (m) to stones (s), and naming the unknown number of stones to find, with the letter "X":
6 m / 7 s = 42 m / X s
cross multiply to get the unknown in the numerator:
6 * X = 42 * 7
divide both sides by 6 to isolate X entirely on the left of the equal sign
X = ( 42 * 7 ) / 6
X = 49
Therefore, there are 49 stones
