Answer: 60cm
Step-by-step explanation:
6 times 2 is 12
12 times 5 is 60
In standard form the two equations are
7x +y = 5
7x +y = -5
The equations describe lines that are parallel.
Answer:
This ratio is 0.6.
Step-by-step explanation:
This ratio is:
gold 37.5%
-------- = ----------- = -0.6
nickel 62.5%
3n-5=-48-40n
Move -40n to the other side. Sign changes from -40n to +40n.
3n+40n-5=-48= -48-40n+40n
3n+40n-5=-48
Move -5 to the other side.
3n+40n-5+5=-48+5
3n+40n=-43
43n=-43
Divide by 43 for both sides
43n/43=-43/43
n=-1
Answer: n=-1
Since 74% of the middle area is bounded, this means that
there is 13% on the left side, and another 13% on the right side.
P (left) = 0.13
P (right ) = 1 - 0.13 = 0.87
At this P values, the z scores are approximately:
z score (left) = -2.22
<span>z score (right) = 1.13</span>
