Answer:
Step-by-step explanation:
The volume of the pyramid is given by:
where 
is the area of the base and 
is the height.
We know that the height is:
Thus we need to find the area of the square at the base.
The perimeter of the square is:
this means that the length of the sides of the square is :
Now we can find the area of the base which the area of the square:
and finally we find the volume:
Which rounded to the nearest tenth of a cubic centimeter is:
Answer:
x = 51
Step-by-step explanation:
The sum of internal angles for this rectangle is 360
x + 81 + 124 + 104 = 360 add like terms
x + 309 = 360 subtract 309 from both sides
x = 51
Answer:
10.27 feet/sec.
Step-by-step explanation:
The distance traveled by the car, d in feet, is given by the function 
.......... (1), where t is the time in seconds.
So, at t= 2 sec, from equation (1) we get d = 1.1 × 4 = 4.4 feet.
Again, at t = 5 sec, we get d = 1.1 × 32 = 35.2 feet.
Now, average speed of the car from t = 2 sec. to t = 5 sec. will be give by
= 
feet/sec. (Answer)
Answer:
x=8
Step-by-step explanation:
The normal distribution is also known as the Gaussian distribution. The correct option is B, while the approx z-score is 0.31.
<h3>What is Normal Distribution?</h3>
The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Since the normal distribution is symmetrical about the mean. Therefore, the correct option is B, while the approx z-score is 0.31.
