Answer: If you add 4+6+8 all together it's 18
Step-by-step explanation: So, the probability of him choosing all those together is 6\18 4\18 and 8\18
hope this helps
have a good day
♥ Chen was here
The margin of error is 1/√n, where n is the number of people
Margin of error = 1/√475 = 0.0458
Multiply by 100 to get percent:
0.0458 x 100 = 4.58% round to 4.6%
The answer is c.
I have solved some examples in the picture

Answer:
see below
Step-by-step explanation:
a. Has a slope of 2 and passes through (10,17)
Using the slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 2x+b
Substitute the point into the equation
17 = 2(10)+b
17 = 20+b
Subtract 20 from each side
17-20 =b
-3 =b
y = 2x-3
b. passes through (1,-4) and (2,-5)
First find the slope
m= (y2-y1)/(x2-x1)
= (-5- -4)/(2-1)
= (-5+4)/(2-1)
= -1/1
= -1
Using the slope intercept form
y = -x+b
Substitute a point into the equation
-4 = -1(1) +b
-4 = -1+b
Add 1 to each side
-3 = b
y = -x+3
