Answer:
(a)
(b)
(c)
Step-by-step explanation:
We are required to construct 3 linear equations starting with the given solution z = 1/3.
<u>Equation 1</u>
<u />
<u />
Multiply both sides by 9
Rewrite 3 as 5-2
9z=5-2
Add 2 to both sides
Our first equation is:
<u>Equation 2</u>
<u /><u />
Multiply both sides by 21
Rewrite 7 as 11-4
21z=11-4
Subtract 11 from both sides
Our second equation is:
<u>Equation 3</u>
<u /><u />
Multiply both sides by 6
Rewrite 6z as 4z+2z
4z+2z=2
Subtract 2z from both sides
Our third equation is:
Answer:
A and B are independent events because P(AIB) = P(A).

Answer:
y = 1/5x -2
Step-by-step explanation:
When a point and slope are given, sometimes it is easiest to start with the point-slope form of the equation. Then it can be rearranged to the desired form.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y -0 = 1/5(x -10) . . . . . line with slope 1/5 through point (10, 0)
y = 1/5x -2 . . . . . . . eliminate parentheses to get slope-intercept form
_____
Note that the slope in the attached picture is 1/5, but your problem text says it is 5. Very different equations will result from these different slopes.
Answer:
10 potatoes.
Step-by-step explanation:
Let x be the number of potatoes.
Then by proportion:
30/12 = x/4
12x = 4*30 = 120
x = 10.
Answer:
3,662
Step-by-step explanation:
It says that x= -10 so you have to multiply 345 by -10 because x is next to the number 345. Then you get the number -3450-212 from there you can see they are both negative so you can add them together and take out the negative symbol at the end. Hope that helped!
