Answer:
Z-score = 1.5
Step-by-step explanation:
Z-score = (x-mean)/standard deviation
= (90-75)/10
= 1.5
We have that
solution is
x <-10 or x>=25
for
x < -10
the solution is the interval (-∞, -10)
and
for
x>=25
the solution is the interval [25,∞)
therefore
the solution for
x <-10 or x>=25
is
(-∞, -10) ∪ [25,∞)
<span>the solution is any value of x less than -10 or greater than or equal to 25</span>
Answer:
none of the two graphs in the pic.
it should be one in the II quadrant
Step-by-step explanation:
the plus four means to move 4 to the left
the plus 2 means to move up 2
That would make the vertex in the II quadrant.

Thanks for free points :)
<span>L the length W the width
The length of a rectangle is 5 more than twice the width</span>
L = 5+ 2W
<span>the perimeter is equal the sum of sides =130
</span>
L+L+W+W =130
by subtitution we replace L by <span>L = 5+ 2W
</span>5+ 2W+<span>5+ 2W +W+W = 130
</span>
6W= 120
w= 20 <span>L = 5+ 2W= 5+ 40=45</span>
