Answer:

A. Based on the procedure by which this figure was generated, it is likely that the population proportion is between 44.5% and 51.5%.

Step-by-step explanation:

Confidence interval:

We build a confidence interval from a sample proportion, to get an estimate of where the population proportion should likely be.

48% of voters surveyed favored the reelection of Congressman Porkbarrel, with a margin of error of 3.5%.

48 - 3.5 = 44.5%.

48 + 3.5 = 51.5%.

Following the concept of a confidence interval, the population proportion is likely to be between 44.5% and 51.5%, and thus, the correct answer is given by option A.

In a triangle , the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 80 mo

Flauer [41]

Answer:

25, 50, and 105.

Step-by-step explanation:

Let the first angle be A, the second angle be B, and the third angle be C.

First, the sum of the three angles in a triangle is 180. Thus:

$A+B+C=180$

We know that the measure of A is twice the measure of B. Thus:

$A=2B$

And the measure of C is 80 more than the measure of B. So:

$C=80+B$

Let's substitute A and C into the original equation:

$2B+B+80+B=180$

Now, let's solve for the second angle (B). Combine like terms:

$4B+80=180$

Subtract 80 from both sides:

$4B=100$

Divide both sides by 4:

$B=25$

So, the second angle is 25 degrees.

This means that the first angle is 2(25) or 50 degrees.

And the third angle is 80+25 or 105 degrees.

And we're done!

The angles are 25, 50, and 105.

Evaluate the intergal F•dr where F (x,y,z)=xyi+yzj+zxk and c is the twisted cubic given by x=t, y=t^2 ,z=t^3, 0<=t=<1

iogann1982 [59]

The integral can be evaluated by substituting everything you know:

$\displaystyle\int_C\mathbf F\cdot\mathrm d\mathbf r=\int_C\mathbf F(x(t),y(t),z(t))\cdot\dfrac{\mathrm d\mathbf r}{\mathrm dt}\,\mathrm dt$

$=\displaystyle\int_0^1(t^3\,\mathbf i+t^5\,\mathbf j+t^4\,\mathbf k)\cdot(\mathbf i+2t\,\mathbf j+3t^2\,\mathbf k)\,\mathrm dt$

$=\displaystyle\int_0^1(t^3+5t^6)\,\mathrm dt$

$=\dfrac{t^4}4+\dfrac{5t^7}7\bigg|_0^1=\dfrac14+\dfrac57=\boxed{\dfrac{27}{28}}$
