Remy, from the blog "Rapping with Remy," asked his readers, "If you had the chance, would you want to be famous?" Of the 2,200 r

eaders who responded, 42% said no, and all were female. What does this show?
possible answers:

No meaningful conclusion is possible without knowing something more about the characteristics of Remy's readers.

The survey is meaningless because of undercoverage bias.

The survey would have been more meaningful if Remy had picked a random sample of the readers who responded.

the survey would have been more meaningful if Remy had used a control group.

This was a legitimate sample, drawn randomly from his readers, and is of adequate size to allow the conclusion that most of Remy's readers want to be famous.

1200 dollars is placed in an account with an annual interest rate of 7.75%. To the nearest year, how long will it take for the a
IRISSAK [1]

Answer:

The time required is about 75 years 3 months

Step-by-step explanation:

We know that the simple interest is expressed as

A = P (1 + rt)

A = final amount =$8200

P = initial principal

: balance=$200

r = annual interest rate 7.75%

7.75/100= 0.0775

t = time (in years)

Substituting our data into the expression we have

8200= 1200(1+0.0775*t)

8200=1200+93t

93t= 8200-1200

93t= 7000

t= 75.27

The time required to get a total amount, principal plus interest, of $8,200.00 from simple interest on a principal of $1,200.00 at an interest rate of 7.75% per year is 75.27 years (about 75 years 3 months)

Evaluate the surface integral. ∫∫s xy ds s is the triangular region with vertices (1, 0, 0), (0, 6, 0), (0, 0, 6)
SashulF [63]
Parameterize the surface \mathcal S by

\mathbf s(u,v)=(\langle1,0,0\rangle(1-u)+\langle0,6,0\rangle u)(1-v)+\langle0,0,6\rangle v
\mathbf s(u,v)=\langle(1-u)(1-v),6u(1-v),6v\rangle

with 0\le u\le1 and 0\le v\le1, which has surface element

\mathrm dS=\|\mathbf s_u\times\mathbf s_v\|\,\mathrm du\,\mathrm dv=6\sqrt{38}(1-v)\,\mathrm du\,\mathrm dv

Then the surface integral becomes

\displaystyle\iint_{\mathcal S}xy\,\mathrm dS=\int_{u=0}^{u=1}\int_{v=0}^{v=1}(1-u)(1-v)(6u(1-v))(6\sqrt{38}(1-v))\,\mathrm dv\,\mathrm du=3\sqrt{\dfrac{19}2}

The table below represents the closing prices of stock ABC for the last five days. What is the r-value of the linear regression
Mekhanik [1.2K]

Answer:

C. -0.68427

Step-by-step explanation:

Enter the data into a graphing calculator.

First decide which is the independent and which is the dependent variable.  Since the value of the stock depends on the day, value will be dependent and day will be independent.

This means that the days will be entered into the first list and the values will be entered into the second list.

Entering these and running the linear regression, we find the r-value to be -0.68427 .
