Answer: A. T2
Step-by-step explanation:
When we first toss a coin then roll a die, then the sample space of the event must contain element that has :
First component of coin : T or H
Second component of dice : 1 , 2 , 3, 4, 5, 6,
The element of the sample space for first tossing a coin then rolling a die will look like: T1, T2, H1, H2, ...... so on.
From all the given options the element of the sample space for first tossing a coin then rolling a die = T2

Answer:
Equation B, 10 + 5.50n = y.
Step-by-step explanation:
N is the pounds of shrimp that were purchased. This has no set value, it can change at any time.
Since each pound of shrimp is $5.50, if you wanted to buy 10 pounds of fish you'd pay $55.
If I wanted to write an equation to find the total amount of money that I'd need to pay for n pounds of shrimp, I would use the equation 5.50n. (I don't know if this makes sense lol I'm terrible at explaining ;-;)
Now, it states that he wants an extra 10 dollars to pay for expenses. On top of the 5.50n, he wants an extra $10.
You need to add 10 to 5.50, in order to get the total amount, or y.
The final equation is going to be 5.50n + 10 = y, or choice B.

Explanation:
a) The velocity curve is linearly increasing from 0 to 6 m/s over a period of 2 seconds, then linearly decreasing from 6 m/s to 0 over the same period. The acceleration is the rate of change of velocity, so for the first half of the motion the acceleration is a constant (6 m/s)/(2 s) = 3 m/s². Similarly, over the second half of the motion, the acceleration is a constant (-6 m/s)/(2 s) = -3 m/s².
The distance traveled is the integral of the velocity, so the linearly increasing velocity will cause the distance vs. time curve to have a parabolic shape. The shape will likewise be parabolic, but with decreasing slope, as the velocity ramps down to zero. Overall, the distance versus time curve will have an "S" shape.
The motion (position and velocity) will be continuous, but the acceleration will not be. There will be a significant "j.erk" at the 2-second mark where acceleration abruptly changes from increasing the velocity to braking (decreasing the velocity).

b) The attachment shows the (given) velocity curve in meters per second and its integral, the position curve, in meters.
The integral in the attached works nicely for machine evaluation. For hand evaluation, it is perhaps best written piecewise:
