The probability that a region prone to hurricanes will be hit by a hurricane in any single year is one tenth or 0.1

P(at least one) = 1 - P(none in five years)

-----

= 1 - 0.90^5

= 1 - 0.59049

=0.40951 or 0.41.

41% probability that there will be a hurricane at least once in the next 5​ years.

Which two equations would be most appropriately solved by using the zero product property? Select each correct answer.
ss7ja [257]

Answer:

1) (x + 4)(x - ½) = 0

4x² + 16x = 0

2) 0.25x² + 0.8x - 8 = 0

3x² - 4x = 15

Step-by-step explanation:

1) (x + 4)(x - ½) = 0

x = -4, ½

4x² + 16x = 0

4x(x + 4) = 0

x = 0, -4

2) (x - 6)(x + 9) = 0

x = 6, -9

(x - 1)² = 4

(x - 1)² - (2)² = 0

(x - 1 - 2)(x - 1 + 2) = 0

(x - 3)(x + 1) = 0

x = 3, -1

These two are easier to solve using product = 0 property, while the other two would be easier using the quadratic formula

How many different four-digit numbers can be made using the digits 1, 2, 3, 4, 5, 6 if no digit can be used more than once?
Alexandra [31]
In the first digit, there are 6 possibilities. In the second, there are 5, because you can't use the digit you used before. In the third, there are 4, and in the fourth, there are 3. So, 

6*5*4*3=360

There are 360 different possible four-digit numbers
