The standard deviation is the square root of the variance...so that means the variance is the standard deviation squared.
2.3^2 = 5.29 <===
Answer:
it would be 200 units
Step-by-step explanation:
if the length is twice the width and the perimeter only being 60 units, you would have 20 as your length and 10 as your width (20+20+10+10=60). Then if you multiply 20 and 10 you get 200
You're given the value of m so you plug that in the equation given to get 1500=-475t+2650. Now with some algebra just solve it for t! so subtract 2650 and get -1150=-475t. Now divide by -475 and get 2.4. Now the t value is already in hours, so there's no conversions, and the closest answer is A! This makes sense because it's an approximation :)
M = 48+x
h=x
x+48+x = 432
2x +48= 432
x=192
