The power goes out as Sandra is trying to get dressed. If she has 9 white T-shirts and 11 colored T-shirts in her drawer, is it

likely that she will pick a colored T-shirt in the dark? What is the probability of Sandra picking a colored T-shirt? Complete the explanation to explain your answers. Enter the probability as a simplified fraction.
Because she has more (white/colored) T-shirts than(white/colored) T-shirts, it is likely she will pick a (white/colored) T-shirt. The likelihood of Sandra picking a colored T-shirt is likely. The probability of Sandra picking a (white/colored) T-shirt is(_____)

Because she has more COLORED shirts then WHITE shirts it is likely she will pick a COLORED shirt.

11 +9 = 20 total shirts

 probability for a colored one = 11/20

Use a graphing utility to approximate (to two decimal places) any relative
iogann1982 [59]

Answer:

Relative minima at (-\frac{7}{2} , -\frac{49}{4} ), and relative maxima DNE.

Step-by-step explanation:

The given function is f(x) = x (x + 7) ...... (1)

We have to calculate the relative maxima and relative minima at point (x, y).

Rearranging the function given above we get.

y= x^{2} +7x = (x + \frac{7}{2} )^{2} -\frac{49}{4}

⇒ y+ \frac{49}{4} = (x + \frac{7}{2} )^{2}

Now, this is an equation of parabola having vertex at (-\frac{7}{2} , -\frac{49}{4} ) and the axis is parallel to positive Y-axis.

Therefore, the function(1) has a relative minima at (-\frac{7}{2} , -\frac{49}{4} ), and the relative maxima DNE. (Answer)

For the following amount at the given interest rate compounded​ continuously, find​ (a) the future value after 9 ​years, (b) the
Stella [2.4K]

Answer:

(a) The future value after 9 ​years is $7142.49.

(b) The effective rate is r_E=4.759 \:{\%}.

(c) The time to reach ​$13,000 is 21.88 years.

Step-by-step explanation:

The definition of Continuous Compounding is

If a deposit of P dollars is invested at a rate of interest r compounded continuously for t years, the compound amount is

A=Pe^{rt}

(a) From the information given

P=4700

r=4.65\%=\frac{4.65}{100} =0.0465

t=9 \:years

Applying the above formula we get that

A=4700e^{0.0465\cdot 9}\\A=7142.49

The future value after 9 ​years is $7142.49.

(b) The effective rate is given by

r_E=e^r-1

Therefore,

r_E=e^{0.0465}-1=0.04759\\r_E=4.759 \:{\%}

(c) To find the time to reach ​$13,000, we must solve the equation

13000=4700e^{0.0465\cdot t}

4700e^{0.0465t}=13000\\\\\frac{4700e^{0.0465t}}{4700}=\frac{13000}{4700}\\\\e^{0.0465t}=\frac{130}{47}\\\\\ln \left(e^{0.0465t}\right)=\ln \left(\frac{130}{47}\right)\\\\0.0465t\ln \left(e\right)=\ln \left(\frac{130}{47}\right)\\\\0.0465t=\ln \left(\frac{130}{47}\right)\\\\t=\frac{\ln \left(\frac{130}{47}\right)}{0.0465}\approx21.88
