Answer:
E(Bases ) = 0.6584499955929 choice C.
Step-by-step explanation:
We want Expected number of bases during 2009
E(bases) = SUM (number of outcomes) *probabiility of outcome
93 + 45 + 1 + 47 = 176 hits
but there are a total of 568 bats
568 - 176 = 392 misses?
E(Bases) = 0* P( miss) + 1 * P( hitting singles) + 2*P(hitting doubles) + 3*P(hitting triples) + 4*P(home run)
E(Bases) = 0 + 93/568 + 2* (45/568) + 3*(1/568) + 4*(47/568)
0.16373239 + 0.158450 + 0.0052816901 + 0.33098591549
E(Bases ) = 0.6584499955929
Answer:
h=2.2
Step-by-step explanation:
All of them would be correct except for the third option, Angle BCA is not equivalent to Angle DCE.
Using the side of the square find the area:
Area = 30^2 = 900 square feet.
The rectangles area is the same, 900 square feet.
Let the width = X
The length would be 2X + 70
Area = length x width
X * 2x+ 70 = 900
This expands to 2x^2 * 70x = 900
Use the quadratic formula to solve for x:
-70 +/- sqrt(70^2-4*2(-900))/2*2
X = 10
Width = x = 10 feet
Length = 2x + 70 = 90 feet
