Answer:
198 is the variance for the number of defective parts made each week.
Step-by-step explanation:
We are given the following in the question:
Number of parts produced each week = 20,000
Percentage of defective parts = 1%
We have to calculate the variance for the number of defective parts made each week.
We treat defective part as a success.
P(Defective part) = 1% = 0.01
Then the number defective parts follows a binomial distribution
.
Formula for variance =
Thus, 198 is the variance for the number of defective parts made each week.
I think its gunna be like 7
The slope-intercept form of the equation of a straight line:
y=mx+b
m=slope
Therefore; in this equation (y=3x+5); m=3
a)
6x+2y=12
2y=-6x+12
y=-6/2 x + 12/2
y=-3x+6 ⇒ m=-3≠3 (this line is not parallel to "y=3x+5")
b)
-3x+y=8
y=3x+8 ⇒ m=3 (this line es parallel to "y=3x+5")
c)
3y=9x
y=9/3 x
y=3x ⇒ m=3 (this line is parallel to "y=3x+5")
d)
y=-x ⇒ m=-1≠3 (this line is not parallet to "y=3x+5")
Therefore; "-3x+y=8" and "3y=9x" are parallel to "y=3x+5".
Answer:
X=7 ST=11 RT=17
Step-by-step explanation:
RT=RS+ST. RS= 2(7)-8. ST=11
X+10=2x-8+11. =14-8=6. RT= x+10
X+10=2x+3. RS=6. 7+10=17
10=x+3. RT=17
X=7
Answer: 8
Explanation:
The number line of cards goes by 1 and the number line of wool goes by 2.
So if Jillian wants 4 cards then he will have trade 8 wool for it. :)
