Simplify algebraic equation x^2-4/x^2+2x
hram777 [196]

Answer:

Simplification of algebric expression is \frac{x^{2} - 2x^{3}-4 }{x^{2} }

Step-by-step explanation:

Simplify any algebric expression means to write an equivalent expression in which all similar terms combined and remove all symbols such as brackets.

The given algebraic equation is x^{2} -\frac{4}{x^{2} } +2x

now for simplifying it

First of all take L.C.M of x^{2}

= \frac{x^{2} (x^{2}) -4 + 2x(x^{2} )}{x^{2} }

We get \frac{x^{2} -4+2x^{3}}{x^{2} }

Further we can write it as  \frac{x^{2} - 2x^{3}-4 }{x^{2} }

Simplification of algebric expression is \frac{x^{2} - 2x^{3}-4 }{x^{2} }

The numbers in green represent mika's random sample of 10 acres. What is the average number of coconut palms on the randomly cho
Alexandra [31]

Answer:

The answers to the questions are

a) The average number of coconut palms on the randomly chosen side is 49.5 coconut  palms

b)  The projected number of palms on the entire farm is 3168 coconut palms.

Step-by-step explanation:

(a) The average is given by ∑fx/∑f = (∑x)/n

The sum of the number of coconut palms in the random sample of 10 acres is as follows

∑x = 56+43+62+63+33+34+38+51+59+56 = 495

n = 10

Therefore the average = 495/10 = 49.5 palm tree per acres

The average number of palm tree per acre = 49.5 palm tree

b) To project the number of coconut palms on the entire farm, we note that the average palm tree per acre = 49.5 coconut  palms

Number of acres = 64

∴ Projected number of coconut  palms in the farm = (Average number of palm tree per acre) × (Number of acres in the farm)

= 64 × 49.5 = 3168 coconut palms.
