Answer:
24 units squared.
Step-by-step explanation:
You can count the individual units to see the length and height, or you can subtract the coordinates. Ex: S-T = length of parallelogram.
Answer : 2 dogs.
Explanation : If there were 2dogs there would be 8 legs. That means 8 legs belong to 4 chickens. 2 dogs and 4 chickens is 12 eyes. If the number of fish is double the number of chickens, there would be 8 fish. 8 fish is 16 eyes. 16 fish eyes + 4 dog eyes and 8 fish eyes is 28 eyes.
Answer:
–0.5
Step-by-step explanation:
Expected value is found by multiplying the probabilities of each roll by the amount won or lost with each roll.
The odd rolls are 1, 3 and 5. The probability of rolling a 1 is 1/6, and the value is 1; this gives us 1/6(1) = 1/6.
The probability of rolling a 3 is 1/6, and the value is 3; this gives us 1/6(3) = 3/6.
The probability of rolling a 5 is 1/6, and the value is 5; this gives us 1/6(5) = 5/6.
Rolling any even number gives us the same value. The probability of rolling an odd number is 3/6, and the value is -4; this gives us 3/6(-4) = -12/6.
Together we have
1/6+3/6+5/6-12/6 = 4/6+5/6-12/6 = 9/6-12/6 = -3/6 = -0.5
