7. The probability that a randomly chosen student will be left-handed is .09: a) In a class of 108, find the probability that th

vampirchik [111]

Solution :

Let x be student will be left handed

P = 0.09

Using the normal approximation to binomial distribution,

a). n = 108,

μ = np = 9.72

$\sigma = \sqrt{np(1-p)}$

$=\sqrt{8.8452}$

= 2.9741

Required probability,

P(x=8) = P(7.5 < x < 8.5)

$=P\left(\frac{7.5-9.72}{2.9741}< \frac{x-\mu}{\sigma}< \frac{8.5-9.72}{2.9741}\right)$

$=P(-0.75 < z < -0.41)$

Using z table,

= P(z<-0.41)-P(z<-0.75)

= 0.3409-0.2266

= 0.1143

b). P(x=12) = P(11.5 < x < 12.5)

$=P\left(\frac{11.5-9.72}{2.9741}< \frac{x-\mu}{\sigma}< \frac{12.5-9.72}{2.9741}\right)$

$=P(0.60 < z < 0.94)$

Using z table,

= P(z< 0.94)-P(z< 0.60)

= 0.8294 - 0.7257

= 0.1006

irinina [24]

Answer: $6n+20$

Distribute

$(4)(5)+(4)(-n)+10n\\20+-4n+10n$

Combine Like Terms

$20+-4n+10n\\(-4n+10n)+(20)\\6n+20$

First of all, you have to understand $g$ is a square-root function.

Square-root functions are continuous across their entire domain, and their domain is all real x-values for which the expression within the square-root is non-negative.

In other words, for any square-root function $q$ and any input $c$ in the domain of $q$ (except for its endpoint), we know that this equality holds: $lim \ q(x)=q(c)$

Let's take $\sqrt{x}$ as an example.

The domain of $\sqrt x$ is all real numbers such that $x \geq 0$ . Since $x=0$ is the endpoint of the domain, the two-sided limit at that point doesn't exist (you can't approach $0$ from the left).

However, continuity at an endpoint only demands that the one-sided limit is equal to the function's value:

$lim \ \sqrt{x} = \sqrt{0} =0$

In conclusion, the equality $lim \ q(x)=q(c)$ holds for any square-root function $q$ and any real number $c$ in the domain of $q$ except for its endpoint, where the two-sided limit should be replaced with a one-sided limit. 

The input $x=-3$ , is within the domain of $g$ .

Therefore, in order to find $lim \ g(x)$ we can simply evaluate $g$ at $x-3$ .

$g(x)$

$\sqrt{7x+22}$

$\sqrt{7(-3)+22}$

$\sqrt{1} =1$
