<span>log(x-3)+log(x) = 2 + log(x+2) 
---------------------------
log[(x-3)x] - log(x+2) = 2
-----
log[(x^2-3x)/(x+2)] = 2
----
(x^2-3x)/(x+2) = 2^2
-------

x^2-3x = 4x+8
x^2 - 7x - 8 = 0
Factor:
(x-8)(x+1) = 0
Positive solution:
x = 8</span>

The probability of flipping a coin and noting Heads is 50%. If you flip the coin 100 times, what is the standard deviation of He
BaLLatris [955]

Answer: 5.000

Step-by-step explanation:

The formula to find the standard deviation for binomial distribution is given by :-

\sigma=\sqrt{np(1-p)}, where p is the probability of getting success in each trial and n is the number of trials.

Given : The probability of flipping a coin and noting Heads is = 0.50

The total number of trials = 100

Then , the standard deviation of Heads to be noted will be :-

\sigma=\sqrt{100(0.50)(0.50)}=5.000

Hence, the standard deviation of Heads to be noted = 5.000

Kirti has developed formulas to help her determine the size of her rectangular flower garden each spring. If she wants to plant
Ksju [112]

Answer:

A(n) = L(n) × W(n) and A(n)=0.5n^{2} +2n+2

Step-by-step explanation:

We are given that the length of the rectangular garden is L and width is W.

Also, in terms of 'n',

Length is given by, L(n) = n + 2

Width is given by, W(n) = 0.5n + 1.

Now, we know that, Area of rectangle = Length × Width.

Therefore, area of Kirti's garden is given by, A(n) = L(n) × W(n).

Thus, formula of area in terms of L(n) and W(n) is A(n) = L(n) × W(n).

Moreover, as A(n) = L(n) × W(n).

i.e. A(n) = (n+2) × (0.5n+1)

i.e. A(n)=0.5n^{2} +n+2 \times 0.5n+2

i.e. A(n)=0.5n^{2} +n+n+2

i.e. A(n)=0.5n^{2} +2n+2

Hence, the formula for area in terms of 'n' is A(n)=0.5n^{2} +2n+2.
