twic as big
Volume of B is 2 times that of Volume of A
Answer:
they bisect each other
Step-by-step explanation:
<em>The diagonals of a parallelogram bisect each other</em>.
__
If they are the same length, the parallelogram is a rectangle. If they cross at right angles, it is a rhombus.
The height of the ball at ground level would be 0 feet.
Set h to 0 and solve for t:
Rewrite the equation as
-5t^2 -2t +49 = 0
Factor -1 out of the equation to get:
5t^2 + 2t -49 = 0
Use the quadratic formula:
-b +/- sqrt(b^2 -4(ac) / 2a
Where a = 5, b = 2 and c = -49
The quadratic formula becomes:
-2 +/-sqrt(2^2 – 4(5*-49) / (2*5)
Simplify to get :
T = -2 +/-sqrt246 / 10
T = 2.936 and – 3.336
Since the time has to be a positive value t = 2.936 seconds.
Rounded to the nearest hundredth = 2.94 seconds.

Answer:
0.3573 = 35.7%
Step-by-step explanation:
We roll a pair of dice 10,000 times so the mean and standard deviation is,
μ = 10000/36 =277.7 σ = 
= (280 - 277.7)/16.4 = .14
= (300 - 277.7)/16.4 = 1.35
Probablity (range)
0.3573
