Answer:
The potato bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the popcorn chip bag assembly line.
Step-by-step explanation:
Popcorn mean= μ`1= 3.06
Popcorn St. Dev= σ1= 0.02
Potato Mean= μ`2= 5.05
Potato St. Dev= σ2= 0.05
Finding the z score
z= x- u / σ
Popcorn z= 3.06- 3.03/0.02= 1.5
Potato Z= 5.05-5.07/0.05= -0.4
The mean is taken to be at zero ( 0) therefore difference of 0.4 is less than a difference of 1.5
Choice 3 is the best option .
Answer:
do you mean PEMDAS?
Step-by-step explanation:
parenthesis, exponents, multiplication, division, addition, and subtraction
you solve in order and go left to right
if you give an equation i can explain it better, but it's basically that
Answer:


Step-by-step explanation:
we are given
speed =8 mph
time = 6 hours
so, we have

now, we can find distance
distance = (speed)*(time)


so, we have

so, our range for x and y can be


Answer:
A (-5,2)
Step-by-step explanation:
5x+y=-23
7x-3y=-41
3×(5x+y)=3×(-23)
15x+3y=-69
<u>+</u><u>7x-3y</u><u>=</u><u>-41</u>
<u>22x</u>=<u>-110</u>
22. 22
x=-5
5x+y=-23
5(-5)+y=-23
-25+y=-23
<u>+25</u><u>.</u> <u>+25</u>
y=2
When using elimination you add both equations together so that one variable cancels out the other. In this situation, y can be the variable. You must get the y-variables to cancel out leaving just the x- variables to solve for.
