Answer:
2
Step-by-step explanation:
Because 3-1 is 2 and 1/4-1/4=0
So 2
I need the answer too. My brother needs it.
Fold tracing paper so that the line segment's endpoints line up with each other , Option D is the correct answer.
<h3>What is a Perpendicular ?</h3>
A perpendicular is a line drawn at 90 degree to a given line or line segment .
Fold tracing paper so that the line segment's endpoints line up with each other.
After drawing a line segment ,
when the end point will be on each other and a crease will be made by pressing the paper , The crease formed will be perpendicular to the line segment.
Therefore, Option D is the correct answer.

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
The given equation is 
where h is the height, in feet, of a ball and t is the time, in seconds.
<u>Part a: The height of the ball when t = 2 seconds:</u>
The height of the ball above the ground 2 seconds after it is released can be determined by substituting t= 2 in the equation , we get;
Simplifying the terms, we get;
Thus, the height of the ball after 2 seconds is 100 feet.
<u>Part b: The height of the ball when t = 4 seconds:</u>
The height of the ball above the ground 4 seconds after it is released can be determined by substituting t = 4 in the equation , we get;
Simplifying the terms, we get;
Thus, the height of the ball after 4 seconds is 68 feet.
