Number 10:
 All angles in a triangle =180 degrees

so add the first to and subtract that by 180

166 degrees

In a survey of 1005 ​adults, a polling agency​ asked, "When you​ retire, do you think you will have enough money to live comfort
Sphinxa [80]

Answer: (0.504, 0.556)

Step-by-step explanation:

Given : Sample size : n= 1005

Number of adults stated that they were worried about having enough money to live comfortably in retirement = 531

Then the proportion of adults stated that they were worried about having enough money to live comfortably in retirement : p=\dfrac{531}{1005}\approx0.53

Significance level : \alpha: 1-0.90=0.1

Critical value : z_{\alpha/2}=1.645

The confidence interval for population proportion is given by :-

p\pm\ z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}\\\\=0.53\pm(1.645)\sqrt{\dfrac{0.53(1-0.53)}{1005}}\\\\\approx0.53\pm0.026\\\\=(0.504,\ 0.556)

Hence, the 90​% confidence interval for the proportion of adults who are worried about having enough money to live comfortably in retirement = (0.504, 0.556)

Use the given conditions to write an equation for the line in point-slope form and general form.
Tasya [4]

Answer:

y=-5x+28 general form

slope point :y-(-7)=-5(x-7)

Step-by-step explanation:

definition :perpendicular slopes are negative reciprocals of each other

x-5y-2=0

y=1/5 x-2/5

slope of the perpendicular line =1/m=-1/(1/5)=-5

slope point :y-(-7)=-5(x-7)

find b :

y=-5x+b

-7=-5(7)+b

b=-7+35=28

y=-5x+28

y=1/5 x-2/5
