For this case we have an equation of the form:
h (t) = - (1/2) * a * t ^ 2 + vo * t + h0
Where,
vo: initial speed
a: acceleration:
h0: initial height.
We have the following equation:
h (t) = - 16t2 + 19t + 110
Therefore, the initial velocity is:
vo = 19 feet / s
Answer:
The initial velocity when the rock is thrown:
vo = 19 feet / s
164+56−(3+4+1)
=220−(3+4+1)
=220−(7+1)
=220−8
=212
You have to do a histogram here:
<span>11 sec: 2 people: probability is 2/50 = 1/25 = 0.04
12 sec: 5 people: probability is 5/50 = 1/10 = 0.1
13 sec: 8 people: probability is 8/50 = 4/25 = 0.16
</span>14 sec: 10 people: probability is 10/50 = 1/5 = 0.2
15 sec: 21 people: probability is 21/50 = 2.38
16 sec: 2 people: probability is 2/50 = 1/25 = 0.04
17 sec: 2 people: probability is 2/50 = 1/25 = 0.04
The answer is c because the two numbers on a number line 16 will be greater then 10
Answer:
5/8
10/8 = 1 2/8 = 1 1/4
15/8 = 1 7/8
20/8 = 2 4/8 = 2/1/2
Step-by-step explanation:
DO NOT multiply both the numerator and the denominator by the same value.
