Find the measure of the angle shown by the arrow(in radians)

soldi70 [24.7K]

Answer:

-7π/3 or -420 degrees

Step-by-step explanation:

So we know that the arrow has made one full rotation and that it is moving in a clockwise direction. So already we have -2π degrees.

The arrow stops at π/6 before the next π/2 rotation. Therefore we find the difference between the two.

π/2 - π/6

3π/6 - π/6 = 2π/6

π/3

Since this is still clockwise, we make this negative. So the measure of the angle shown by the arrow is -2π - π/3

Answer:

Interval estimate for the proportion of all homeowners in the United States that hold a home equity loan lie between (.17033 , .22967 ) or 17% to 22.9%

Step-by-step explanation:

Given -

In a recent poll of 1,200 homeowners in the United States, one in five homeowners reports having a home equity loan that he or she is currently paying off.

If one in five homeowners reports having a home equity loan then for 1200 homeowners = $\frac{1200}{5}$ = 240 homeowners reports having a home equity loan.

Sample proportion $(\widehat{p})$ = $\frac{240}{ 1200}$ = 0.2

confidence coefficient = 0.99

$(\alpha)$ = 1 - confidence coefficient = 1 - 0.99 = .01

$z_{\frac{\alpha}{2}} = z_{\frac{.01}{2}}$ = 2.58

interval estimate for the proportion of all homeowners in the United States that hold a home equity loan

= $\widehat{p}\pm z_{\frac{\alpha}{2}}\sqrt\frac{{\widehat{p}( 1 - \widehat{p})}}{n}$

= $0.2\pm z_{\frac{.01}{2}}\sqrt\frac{{0.2( 1 - 0.2)}}{1200}$

= $0.2\pm 2.58\times \sqrt\frac{{0.2( 0.8)}}{1200}$

= $0.2\pm .02967$

= $(0.2 - .02967 ) , (0.2 + .02967)$

= (.17033 , .22967 )
