Step-by-step explanation:
The difference in weights compared over the two different groups is significant and at 0.05 level of significance, the age of men is directly linked with their mean weight.
Answer:
Option c is correct
226 feet is the maximum height of the projectile.
Step-by-step explanation:
A quadratic equation , ....[1]
then the axis of symmetry is given by:
As per the statement:
The path of the projectile is modeled using the equation :
....[2]
where, h(t) is the height after t time.
On comparing with [1] we have;
a = -16 and b = 48
then;
sec
Substitute this in [2] we have;
⇒
Simplify:
Therefore, the maximum height of the projectile at 1.5 sec is, 226 feet.
ok so I am no expert (Actually i am it says it on my profile) but the answer is 69/5555*^ I hope that this helps you and if it was so easy then why can't ya do it buddy! lol jkjkjkjk
