Answer:
16 comets
Step-by-step explanation:
This is like a simple versions of systems of equations.
You'd want to create 2 equations describing the two pieces of information they give you. First, define the variables:
# of Fantails = f
# of Comets = c
You know Gloria has 22 total, so f + c = 22
You also know there are 10 fewer f than c, so c - 10 = f
In this case, you can substitute "f" in and solve for c.
(c - 10) + c = 22
2c - 10 = 22
2c = 32
c = 16

Mean (average) - add all numbers up and divided by the number of addends
Mean = 46.19047619 (50)
Median - arrange numbers in numerical order, and find the one in the middle
Median = 35
Mode - number that appears the mode
Mode = 80
Range - difference between biggest and smallest number
Range = 80

Answer:
0.5054
Step-by-step explanation:
This is a question on conditional probability.
We solve using Baye's Theorem of conditional probability
From the question
The probability of having a particular disease = 0.08.
The probability of not having a particular disease = 1 - 0.08 = 0.92
The probability of testing positive for the disease is given that a person has the disease = 0.94
The probability of testing positive given that the person does not have the disease = 0.08
Given that a person tests positive for the disease, the probability that they actually have the disease is
= (0.08 × 0.94)/(0.08 × 0.94) + (0.08 × 0.92)
= 0.0752/0.0752 + 0.0736
=0.0752/ 0.1488
= 0.5053763441
≈ Approximately to 4 decimal places = 0.5054
