Answer:
A. Angel fish = 48
B. Gold fish = 36
Step-by-step explanation:
Clown fish : angel fish = 5 : 4
Angel fish : gold fish = 4 : 3
Clown fish = 60
A. How many angel fish are there
Let x = number of angel fish there
Clown fish : angel fish = 5 : 4
Clown fish : angel fish = 60 : x
Equate the ratios
5 : 4 = 60 : x
5/4 = 60/x
Cross product
5 * x = 4 * 60
5x = 240
x = 240/5
= 48
x = 48
Angel fish = 48
B. How many gold fish are there
Let
y = number of gold fish there
Angel fish : gold fish = 48 : y
Angel fish : gold fish = 4 : 3
Equate both ratios
48 : y = 4 : 3
48/y = 4/3
Cross product
48 * 3 = y * 4
144 = 4y
y = 144/4
= 36
y = 36
Gold fish = 36
Answer:
= 4n
Step-by-step explanation:
Note that the values on the second row are 4 times the corresponding values on the first row , that is
1 × 4 = 4
5 × 4 = 20
10 × 4 = 40
12 × 4 = 48
15 × 4 = 60
25 × 4 = 100
Then
n × 4 = 4n ← nth term rule
Answer:
Continous distributions:
- A probability distribution showing the average number of days mothers spent in the hospital.
- A probability distribution showing the weights of newborns.
Step-by-step explanation:
A probability distribution showing the number of vaccines given to babies during their first year of life will have a discrete distribution as only a natural number can represent the number of vaccines (0, 1, 2 vaccines and so on).
A probability distribution showing the average number of days mothers spent in the hospital can be described as continous because we are averaging days and this average can be fractional, so it is not discrete.
A probability distribution showing the weights of newborns is continous, as the weights are a continous variable (physical measurement), not discrete.
A probability distribution showing the amount of births in a hospital in a month is a discrete distribution, as the number of births can only be represented by natural numbers.
