Add up the base lengths: 22+29 = 51
Divide that result over two: 51/2 = 25.5
Answer: 25.5
Answer:
I THINK ITS 14 SIS PURRRR
Answer:
a)
b)
And we can use the complement rule and we have this:
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
The complement rule is a theorem that provides a connection between the probability of an event and the probability of the complement of the event. Lat A the event of interest and A' the complement. The rule is defined by:
Solution to the problem
For this case we define the random variable X="number of children unvaccinated" and the distribution for X is given by:
Part a
For this case we want this probability:
Using the probability mass function we can replace and we got:
Part b
For this case we want this probability:
And we can use the complement rule and we have this:

Answer:
Arrow C.
Step-by-step explanation:
Out of three arrows, nearest arrow from the origin will be the best arrow.
Ordered pair for arrow A → (-5, 4)
Distance between A and bullseye =
=
=
= 6.40 units
Ordered pair for arrow B → (5, -5)
Distance between B and bullseye =
=
= 7.1 units
Ordered pair for arrow C → (-2, -6)
Distance between C and the bullseye =
=
= 6.32 units
Distance between C and the bullseye is the shortest.
Therefore, arrow C will be the best arrow.
