The empirical rule for a normal distribution states that 95% of the data points lie within plus and minus two standard deviations from the mean. 30 is two standard deviations below the mean and 42 is two standard deviations above the mean.
Therefore, 95% if the employees are between 30 and 42 years old.
Answer:
Step-by-step explanation:
use the point slope formula
y - y1 = m(x -x1)
where "m" is an undefined slope
and plug in the given point (4,7) it's form is (x1,y1)
y-7 = m(x - 4)
y = m(x - 4 ) + 7
The cash payment for the article is RS. 2,260.
A discount reduces the price of an item. The article becomes cheaper after the discount.
Cost of the article after the RS. 20 discount = RS. 2020 - 20 = RS 2000
VAT means value added tax. VAT increases the price of an item. The cost of the article increases by 13% after the VAT is levied,
Cost of the article = (100 + 13%) x 2000
1.13 x 2000 = RS 2,260.

Answer: Let the width of the garden be x then the length of garden will be 2x+10.
Step-by-step explanation:
Consider a single variable 'x' for the given statement.
To evaluate an algebraic expression, we have to substitute a number for each variable and perform the arithmetic operations.
Let x denote the width of the garden.
Since , The length of the garden is 10 feet longer than double the width.
Multiply x with 2 and after that add 10 to it, we get
The length of garden will be '2x+10'
