Answer:
(0, -2)
Step-by-step explanation:
Step 1: Write equation in slope-intercept form
-3y = 6 - 2x
y = -2 - 2/3x
Step 2: Find y-int
y = -2 -2/3(0)
y = -2
(0, -2)
Answer:
0.6154 or 61.54%
Step-by-step explanation:
Machine B output level= 80%
Machine A output level= 20%
Machine B defective rate = 0.04
Machine A defective rate = 0.10
The proportion of total washers that are defective is:
![D=0.8*0.04+0.2*0.1\\D=0.052](https://tex.z-dn.net/?f=D%3D0.8%2A0.04%2B0.2%2A0.1%5C%5CD%3D0.052)
Therefore, the probability that a randomly selected washer was manufactured by machine B, given that it is defective, is determined by the proportion of defective washers produced by machine B divided by the proportion of total defective washers:
![p=\frac{0.8*0.04}{0.052}\\p=0.6154=61.54\%](https://tex.z-dn.net/?f=p%3D%5Cfrac%7B0.8%2A0.04%7D%7B0.052%7D%5C%5Cp%3D0.6154%3D61.54%5C%25)
The probability is 0.6154 or 61.54%.
Answer: y = -6x + 5
Step-by-step explanation:
equastion is y = dx + e
+) Because it perpendicular y = \dfrac{1}{6} x + 3
d \times \dfrac{1}{6} = -1
<=> d = -1 : \dfrac{1}{6}
<=> d = -6
=> y = -6x + e;
+) Because it contains the point (-3; 23)
=> 23 = -6 \times (-3) + e
<=> e = 5
=> y = -6x + 5

My bad dint mean to answer :/
Step-by-step explanation:
Answer:
y=35z+20
Step-by-step explanation:
Y is the total cost, so it goes on the outside. 35z represents the months of service because you multiply 35 by however many months there are (for example, if you had 3 months, you'd have $35 3 times). Finally, the $20 is tacked onto the end because that's the initial payment to open an account
