To ease the understanding, let's write it in degrees and not in Radian:
Formula of conversion: Degree°/180 = Radian/π
Convert 7π/4 in degrees: = (7x180)/4 = 315°
This angle is in the IV th Quadrant of the UNIT circle. So you can write 315° or - 45° .
sin(7π/4) = sin(315°) = sin( - 45°) = - sin(45°) = - (√2)/2
Answer:
P(X ≤ 5) = 0.84134
Step-by-step explanation:
This is a normal distribution problem with
μ = mean = 4 years
σ = standard deviation = 1 year
To find the probability that a terminal will last 5 years or less using excel, we follow these steps. P(X ≤ 5)
- Use an empty cell.
- Right click and go to “Insert Formula”.
- In the searchbox, type “Normdist” and click “Go.”
- Pick “NORMDIST” from the list and then click “OK” to open the Function Arguments window.
- Enter the data into the box. Type “5” in the X box, “4” in the Mean box, “1” in the Standard Deviation box and “true” in the cumulative box..
- Click “OK.”. This returns 0.84134474 in the cell you clicked in Step 1, which is the probability that a terminal will last 5 years or less using excel, we follow these steps. P(X ≤ 5).
P(X ≤ 5) = 0.84134
The small box is 384inches squared for the volume and the larger box is 2,700 inches squared so if you place the smaller box inside the larger box the room left inside the larger box would be 2,316 inches squared
Answer:
- Robert is wrong, the correct answer is 4 times greater
Step-by-step explanation:
Area is the product of two dimensions.
If each dimension is doubled, then the area becomes 2*2 = 4 times greater.
If each face is 4 times greater, then their sum will be 4 times greater.
The sum of the faces is the total surface area, therefore the B's surface area is 4 times as great as A's surface area.
The function represents the height of the object after t seconds is
Step-by-step explanation:
The projectile motion of an object is modeled by the function
where, v is the initial velocity of the object,
c is the initial height of the object,
t represents the time the object is in motion.
Given that v=59 ft/s and intial height is h(0)=6 ft
h(0)=6 ft
h(0)=
h(0)=c
So, c= 6
Therefore, The function represents the height of the object after t seconds is
