Answer:
Mininum value of K is 220
Step-by-step explanation:
400 people has a "yes" answer for the first question and 220 people has a "yes" answer for the second question
There is a possibility that 220 out of the 400 people that has a "yes" answer for the first question also has a "yes" for the second question
Therefore, the minimum number of people that has two "yes" answer (K) is 220
I believe the answer is c
Your answer is going to be 23/22
Answer:
Pat a) The graph in the attached figure
Part b) ![y=(4/3)x-5](https://tex.z-dn.net/?f=y%3D%284%2F3%29x-5)
The slope is ![m=(4/3)](https://tex.z-dn.net/?f=m%3D%284%2F3%29)
The y-coordinate of the y-intercept is ![b=-5](https://tex.z-dn.net/?f=b%3D-5)
Step-by-step explanation:
Part a) Which line represents the linear equation
?
To graph the linear equation find the intercepts
we know that
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0
![-3y=15-4(0)](https://tex.z-dn.net/?f=-3y%3D15-4%280%29)
![-3y=15](https://tex.z-dn.net/?f=-3y%3D15)
![y=-5](https://tex.z-dn.net/?f=y%3D-5)
The y-intercept is the point ![(0,-5)](https://tex.z-dn.net/?f=%280%2C-5%29)
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0
![-3(0)=15-4x](https://tex.z-dn.net/?f=-3%280%29%3D15-4x)
![4x=15](https://tex.z-dn.net/?f=4x%3D15)
![x=15/4=3.75](https://tex.z-dn.net/?f=x%3D15%2F4%3D3.75)
The x-intercept is the point ![(3.75,0)](https://tex.z-dn.net/?f=%283.75%2C0%29)
Plot the intercepts to graph the linear equation
see the attached figure
Part b) Rewritten in slope-intercept form
we know that
The equation of the line into slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope
b is the y-coordinate of the y-intercept
we have
![-3y=15-4x](https://tex.z-dn.net/?f=-3y%3D15-4x)
convert to slope intercept form
isolate the variable y
![3y=4x-15](https://tex.z-dn.net/?f=3y%3D4x-15)
![y=(4/3)x-5](https://tex.z-dn.net/?f=y%3D%284%2F3%29x-5)
The slope is ![m=(4/3)](https://tex.z-dn.net/?f=m%3D%284%2F3%29)
The y-coordinate of the y-intercept is ![b=-5](https://tex.z-dn.net/?f=b%3D-5)
Answer:
About $437.25
Step-by-step explanation:
Using the table which gives the annual premium per $1000; the premium paid annually by the 40 year old male is $437.23
The total annual premium = $75000
Using the data in the table :
Annual premium per $1000 of coverage for a 40-year old male with a 10 - years life insurance policy = $5.83
The annual premium for $75,000 ;
Premium per $1000 × ($75000/$1000)
Annual premium = $5.83 × ($75,000/1000)
Annual premium = $5.83 × 75 = $437.25
Hence, the annual premium for the lifetime insurance based on the stated conditions is $437.25
