Answer:
1/3; 33% chance
Step-by-step explanation:
1/2 (prob. of tossing tails) * 2/3 (prob of rolling < 2) = 1/3
Given:
Latasha spends $3.35
Helen spends 4 times as much as Latasha.
Dee spends $7.50 more then Helen.
To find:
The amount Dee spends.
Solution:
It is given that, Latasha spends $3.35.
Helen spends 4 times as much as Latasha.
So, Helen spends = 4 × $3.35
= $13.40
Dee spends $7.50 more then Helen.
Dee spends = $13.40+$7.50
= $20.90
Therefore, dee spends $20.90.
135 degrees is your answer
Answer:
65.5
Step-by-step explanation:
(74 + 57)divided by 2 = 65.5
Answer:
axis of symmetry x=3/2
vertex (3/2, 0)
Step-by-step explanation:
to find the axis of symmetry we use h = -b/2a
where ax^2 + bx+c
h = -(-12)/2(4)
h= 12/8
h = 3/2
the axis of symmetry is x = 3/2
the x coordinate of the vertex is h x=3/2
to find k, the y coordinate of the vertex, substitute x=3/2 into the equation
y=4x^2-12x+9
y=4(3/2) ^2-12(3/2)+9
= 4 (9/4) - 6*3 +9
= 9-18+9
= 0
the vertex (3/2, 0)
