75 percent of the number 140 is 105.
Let the unknown number be x.
Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Here, 75% of x is 105
75% of x= 105
75/100 ×x= 105
0.75x=105
x=105/0.75
x= 140
Therefore, 75 percent of the number 140 is 105.

I cant see all the question but this is how you find the derivative of your function using the product rule.
Here you use the extension of the product rule to 3 factors which we'll write as:-
f(x), g(x) and h(x):-
Derivative = f'(x) g(x) h(x) + f(x) g'(x) h(x) + f(x) g(x) h'(x)
(3x - 1)(x + 4)(2x - 1)
derivative = 3(x + 4)(2x - 1) + (3x + 1)(1)(2x - 1) + (3x - 1)(x + 4)(2)
= 3(x + 4)(2x - 1) + (3x + 1)(2x - 1) + 2(3x - 1)(x + 4)
the yard? (Assume two mowers are available.)
I would assume it would take 3.5 hours to mow the lawn together.
In a normal distribution, the mean has Standard Score: z =
Using the normal distribution, it is found that the z-scores are:
1) z = -0.8
2) z = 2.4
3) z = 0
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
Item 1:
0.8 standard deviations below the mean, hence z = -0.8.
Item 2:
2.4 standard deviations above the mean, hence z = 2.4.
Item 3:
The mean is 0 standard deviations from itself, hence z = 0.

A standard score (z-score) signifies how many standard deviations a data point is away from the mean. A data value 0.8 standard deviations below the mean has a z-score of -0.8, meanwhile, if it is 2.4 standard deviations above the mean, its z-score is 2.4. The mean in a normal distribution has a z-score of 0.
In the field of statistics, a standard score (also known as a z-score) represents how many standard deviations an element is from the mean. In a normal distribution, a data value located 0.8 standard deviations below the mean has a Standard Score: z = -0.8. This is because the z-score is negative when the data value is below the mean. Conversely, a data value located 2.4 standard deviations above the mean has a Standard Score: z = 2.4. As the data value is above the mean, the z-score is positive. Finally, for the mean value itself in a normal distribution, the Standard Score: z = 0 because the mean value is the center of distribution, hence no deviation from itself.
