Answer:
h = 8
Step-by-step explanation:
Area of rectangle: base * height
So, by substituting the values given, we can write this equation:
Note: 1/4 = 0.25, so 3 1/4 = 3.25
A = b * h
26 = 3.25 * h
Divide both sides by 3.25.
h = 8

E) 12 minutes
A normal curve has approximately 95% of graph between mean - 2sd and mean + 2sd
So 95% of the times will be between 0 and 12 minutes. 6 - 2x3 to 6 + 2x3
2.5% will take over 12 minutes
Strangely 2.5% will also take less than 0 minutes to process which shows the normal curve is not perfect in this example.
You would take 3 x 4 which equals 12. And then you would take 12 x8 which would equal 96
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!
I don’t know sorry please somebody else can help you
