Answer:

4x^2 - 5.

Step-by-step explanation:

h(x) = x^2 - 5

Replace the x in h(x) by 2x:

h(2x) = (2x)^2 - 5

        =  4x^2 - 5.

three zebras are chilling in the desert. suddenly a lion attacks. each zebra is sitting on a corner of an equally length triangl
AnnyKZ [126]

Probability that no zebras collide is 0.25

The zebras are represented as z1, z2 and z3.

Z1 to B, Z2 to C, and Z3 to A come first = (\frac{1}{2})^3

Following that, z1 to C, z2 to A, and z3 to B = (\frac{1}{2})^3

Consequently, the likelihood of no collision is 2×1/8 = 0.25.

<h3>What are the types of probability distributions ?</h3>

Discrete and continuous probability distributions are the two main categories in which probability distributions fall. There are numerous varieties of probability distributions within each category.

  • The number of favorable outcomes of an event divided by the total number of possible outcomes of an event can be used to calculate the probability of an event.
  • The likelihood of a sure or certain event is one.
  • The likelihood of an impossibility is 0 (0).
  • Every event has a probability between 0 and 1.
