Answer:
Step-by-step explanation:
Divide 8 1/4 by 6 7/8 and the answer will be 1.2 times heavier.
8 1/4 is 8.25 and 6 7/8 is 6.875 in decimal point and again:
8.25 divided by 6.875 is 1.2.
Answer:1,200 meters per minute
Step-by-step explanation:
Answer: A projectile reaches its highest point when its vertical velocity component is zero.
Step-by-step explanation:
In projectile motion, objects moves in parabolic path.
Projectile motion is a type of motion in which an object moves in a bilaterally symmetrical, parabolic path. Projection motion happens when the force is applied at the start of the trajectory (where the object follows) which follows an interference which is gravity. Gravity takes over and afterwards the object accelerates downwards. The acceleration is constant so the vertical velocity (Vy) varies linearly. The maximum height of the projectile which is the highest height is reached when the vertical velocity (Vy) is equal to zero.
After the projectile reaches its maximum height which is its highest point, it begins to drop downwards.
Answer:

--- Variance
Step-by-step explanation:
Given

Solving (a): Calculate the mean.
The given data is a grouped data. So, first we calculate the class midpoint (x)
For 51 - 58.

For 59 - 66

For 67 - 74

For 75 - 82

For 83 - 90

So, the table becomes:

The mean is then calculated as:



-- approximated
Solving (b): The sample variance:
This is calculated as:

So, we have:


-- approximated
To find this you would do 800 + 15x where x is the amount of years.
For 9 years it would be 800 + 15(9) which is 800 + 135.
At the end of 9 years, the apartment's rent would be $935. I hope that's utilities included because... yikes...
