Answer:

(We already know that: x -1/x-1 = 1 and x + 1/x + 1 = 1 there is no need of keeping them)

  (x-1/x-1) x+5/x+1 -x-2/x-1(x+1/x+1)

= x + 5/x + 1 - x - 2/x - 1

= x²/x + 5/x + x/x - x²/x - 2/x - x/x

= x² + 5 + x - x² - 2 - x

= 5 -2

= 3

X+2/3=9/10 what does x equal
PtichkaEL [24]

Answer:

x = 7/30

Step-by-step explanation:

Identify the LCD; it is 30.  30 is the smallest number divisible by both 3 and 10.

Then we have:

(30/30)x + 20/30 = 27/30.

Clearing out the fractions, we get:

30x + 20 = 27, or 30x = 7

Dividing both sides of this result by 30 yields x = 7/30.

assume that when adults with smartphones are randomly selected, 44% use them in meetings or classes. If 10 adult smartphones use
tensa zangetsu [6.8K]

Solution: The given random experiment follows Binomial distribution with n=10,p=0.44

Let X be the number of adults who use their smartphones in meetings or classes.

Therefore, we have to find:

P(X

We know the binomial model is:

P(X=x)=\binom{n}{x} p^{x} (1-p)^{n-x}

\therefore P(X

                       =\binom{10}{0}0.44^{0}(1-0.44)^{12-0}+\binom{10}{1}0.44^{1}(1-0.44)^{10-1}+\binom{10}{2}0.44^{2}(1-0.44)^{10-2}

                       =1 \times 1 \times 0.0030 + 10 \times 0.44 \times 0.0054 + 45 \times 0.1936 \times 0.009672

                       =0.0030+0.0238+0.0843

                       =0.1111

Therefore, the probability that fewer than 3 of them is 0.1111
