Which linear function represents the line given by the point-slope equation y + 7 = –y plus 7 equals negative StartFraction 2 Ov

Citrus2011 [14]

Answer:

Negative Start Fraction 2 Over 3 End Fraction x minus 11

$f(x)=-\frac{2}{3}x-11$

Step-by-step explanation:

we have

$y+7=-\frac{2}{3}(x+6)$

Convert to slope intercept form

$y=mx+b$

Solve for y

That means -----> Isolate the variable y

Distribute in the right side

$y+7=-\frac{2}{3}x-\frac{2}{3}(6)$

$y+7=-\frac{2}{3}x-4$

subtract 7 both sides

$y=-\frac{2}{3}x-4-7$

$y=-\frac{2}{3}x-11$

Convert to function notation

Let

f(x)=y

$f(x)=-\frac{2}{3}x-11$

therefore

The linear function is

Negative Start Fraction 2 Over 3 End Fraction x minus 11

If XX is a binomial random variable, compute the mean, the standard deviation, and the variance for each of the following cases:

Liula [17]

Answer:

(a) The mean, variance and standard deviation of X are 1.60, 0.96 and 0.98 respectively.

(b) The mean, variance and standard deviation of X are 3.20, 0.64 and 0.80 respectively.

(c) The mean, variance and standard deviation of X are 1.50, 0.75 and 0.87 respectively.

(d) The mean, variance and standard deviation of X are 4.00, 0.80 and 0.89 respectively.

Step-by-step explanation:

The random variable X follows a Binomial distribution with parameters n and p.

The mean, variance and standard deviation of X are:

$\mu=np\\\sigma^{2}=np(1-p)\\\sigma=\sqrt{np(1-p)}$

(a)

For n = 4 and p = 0.40 compute the mean, variance and standard deviation of X as follows:

$\mu=np=4\times0.40=1.60\\\sigma^{2}=np(1-p)=4\times0.40\times(1-0.40)=0.96\\\sigma=\sqrt{np(1-p)}=\sqrt{0.96}=0.98$

Thus, the mean, variance and standard deviation of X are 1.60, 0.96 and 0.98 respectively.

(b)

For n = 4 and p = 0.80 compute the mean, variance and standard deviation of X as follows:

$\mu=np=4\times0.80=3.20\\\sigma^{2}=np(1-p)=4\times0.80\times(1-0.80)=0.64\\\sigma=\sqrt{np(1-p)}=\sqrt{0.64}=0.80$

Thus, the mean, variance and standard deviation of X are 3.20, 0.64 and 0.80 respectively.

(c)

For n = 3 and p = 0.50 compute the mean, variance and standard deviation of X as follows:

$\mu=np=3\times0.50=1.50\\\sigma^{2}=np(1-p)=3\times0.50\times(1-0.50)=0.75\\\sigma=\sqrt{np(1-p)}=\sqrt{0.75}=0.87$

Thus, the mean, variance and standard deviation of X are 1.50, 0.75 and 0.87 respectively.

(d)

For n = 5 and p = 0.80 compute the mean, variance and standard deviation of X as follows:

$\mu=np=5\times0.80=4.00\\\sigma^{2}=np(1-p)=5\times0.80\times(1-0.80)=0.80\\\sigma=\sqrt{np(1-p)}=\sqrt{0.80}=0.89$

Thus, the mean, variance and standard deviation of X are 4.00, 0.80 and 0.89 respectively.

Please. help. now. thanks. so. much.

Brut [27]

Answer:

318.395976 in

Step-by-step explanation:

The formula for the area of a square is A = s². s is the length of one side.

Solve the formula for area to find the length of a side.

A = s²

176 = s²

s = √176

s ≈ 13.266499 in

Count how many sides consist of the perimeter. I counted 24. Multiply 24 by the length of one side.

24 × 13.266499 = 318.395976
