Answer:
2.4
Step-by-step explanation:
12 ÷ 5 = 2.4
have a nice day!
Vertex is highest point
ok so the t value of the vertex of a function in the form
f(x)=at^2+bt+c is
-b/2a
find t value
h(x)=-16t^2+50t+6
a=-16
b=50
-50/(2*-16)=1.5625
round
1.6 seconds
max height
input 1.6 for t and evaluate (for more precice, input 1.5625 for t)
max height is 45 feet
seems to be
b=initial velocity
c=intial height
a=-16
eqation is
h(t)=-16t^2+70t+5
vertex is -70/(2*-16)=2.1875
input for t to get max height
82 feet
answers are
1.6 seconds
45 feet
82 feet

Step-by-step explanation:
a) X is a discrete uniform distribution. As the number of outcomes is only 3.
b) sum is at least 4
X ≥ 4
i.e (1,3) or (2,3)
probability of X ≥ 4 is 2/3
2/3= 0.667
66.7 % is the probability of the outcome to have a sum at least 4.
c) The 3 likely outcome of X
<em>(1,2) where X ; </em> 1+2=3
<em>(1,3) where X ;</em> 1+3=4
<em>(2,3) where X ;</em> 2+3=5
Mean = 3+4+5/ 3
Mean = 4
