Let's denote X as the numbered marbles.
P(21≤ X ≤27) = 0.4332
P( 0 ≤ z ≤ 6/σx) = 0.4332; Z is the z-score here
1.5 = 6/σx
σx = 4
Answer:
I will assume the second equation is y=2x^3. If it is y=2x+3 or y=2x-3, the lines will never intersect: they have the same slope (2):
Step-by-step explanation:
2x – y = 7 can be rewritten as: y = 2x -7. It has a slope of 2. The second equation, y = 2x 3, isn't clearly written. If the 3 has a plus or minus sign, then the lines will never intersect: they have the same slope, 2.
I'll assume the second equation is y=2x^3.
See attached graph.
Answer:
True
Step-by-step explanation:
8a -(8a - 8)
Multiply - to the inside (_) terms
8a - 8a + 8
Subtract 8a - 8a
You get 8 left
:)
Brainiest plz?
X = 13
13 x 8 = 104
2(13) + 14 = 40
104 + 40 + 36 = 180
(24 m)*(4 m) = (5 m)*height . . . . . area is the same no matter which base you use
height = (4/5)*(24 m) = 19.2 m
