Answer:</h2>
a)
The probability both are math phobic: 0.0144 or 1.44%
b)
The probability that atleast one is math phobic is: 0.2256 or 22.56%
<h2>
Step-by-step explanation:</h2>
It is given that:
About 12% of the population of a large country is math phobic.
This means that the probability that a randomly selected person is math phobic is: 0.12
If two people are randomly selected.
a)
The probability both are math phobic:
This means that the first person selected is math phobic and the second person selected is also math phobic.
= 0.12×0.12
= 0.0144
which in percent is: 1.44%
b)
The probability that atleast one is math phobic is:
1-none is math phobic.
= 1-(1-0.12)×(1-0.12)
=1- 0.88×0.88
= 0.2256
which in percent is: 22.56%
Answer:

Answer:
4 cm
Step-by-step explanation:
The volume (V) of milk in the container is
V = 8 × 5 × 12 = 480 cm³
The volume remains the same whatever the position of the container.
let d be the depth then
8 × 15 × d = 480
120d = 480 ( divide both sides by 120 )
d = 4 cm
We can expand this expression using foil method (multiply first terms, outer terms, inner terms then last terms together):
<span>(x+4)(x+6)
x^2 + 6x + 4x + 24
combine like terms
x^2 + 10x + 24
This is also the final simplified expression. It cannot be further expanded or simplified. Foil method is the easiest way to expand expressions.</span>
