The probability that has a basic model purchase extended warranty will be 0.1935 or 19.35%.
<h3>What is probability?</h3>
Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
A company that manufactures video cameras produces a basic model and a deluxe model.
Over the past year, 45% of the cameras sold have been of the basic model.
Of those buying the basic model, 43% purchase an extended warranty, whereas 50% of all deluxe purchasers do so.
If you learn that a randomly selected purchaser has an extended warranty.
Then the probability that has a basic model purchase extended warranty will be
P = 0.45 × 0.43
P = 0.1935
P = 19.35%

Answer:
$15.5
Step-by-step explanation:
let a = price of one orchid plant
8 orchids would cost 8 x a = 8a
12 orchids would cost 12 x a = 12a
Let b = price of one lily plant
12 lilies would cost 12 x b = 12b
8 lilies would cost 8 x b = 8b
8a + 12b = 362 -- eqn 1
12a + 8b = 388 -- eqn 2
to solve, multiply equation 1 by 8 and equation 2 by 12
64a + 96b = 2896 equation 3
144a + 96b = 4656 equation 4
substract equation 4 from 3
80a = 1760
a = $22
Substitute for a in eqn 1 and solve for b
8(22) + 12b = 362
b = $15.5
(See attached diagram.) The positions of the vaulter's left and right hands are marked. The length of the entire pole is 15 feet. The segment below her left hand is twice as long as the segment above, so label those two parts with x and 2x. Those two segments add up to 15 feet:
The lower segment is 10 feet long. The vaulter's right hand is 1.5 feet above her left, so it is 10 + 1.5 = 11.5 from the bottom of the pole.
