We have that
using a graph tool
see the attached figure
case A) x − 2y > 3
this <span>inequality represented the graph
case B) </span><span>x − 2y < 3
</span>this inequality not represented the graph
case C) <span>2x − y > 3
</span>this inequality not represented the graph
case D) <span>2x − y < 3
</span>this inequality not represented the graph
the answer isthe option <span>
A, x − 2y > 3</span>
Answer:
624
Step-by-step explanation:
Plug into the formula, SA=bh+(s1+s2+s3)H.
H=14
s1=13
s2=13
s3=10
Hope that helps!
<h3>
Answer: 9 inches (choice D)</h3>
Work Shown:
V = volume of pyramid
V = (1/3)*(area of base)*(height)
V = (1/3)*(12*10)*h
V = (1/3)*120h
V = 40h
Set this equal to the given pyramid volume 360 cubic inches and solve for h
40h = 360
h = 360/40
h = 9
The way to do this question is : difference of the two sides < x < sum of the two sides. so for 1) 4 < x< 8
2) 8 < x< 16
3) 9 < x < 13
i’m pretty sure this is right! hope it helps!
According to the empirical rule, roughly 68% of the scores fall between z = -1 and z = 1
You can use a calculator to get a more approximate answer. If you have a TI calculator, you can use the "normalcdf" function to type in normalcdf(-1,1)
