Explanation:
Midline: it is a horizontal line where half of the function above it and half of the function is below it.
Amplitude: It means how far the function varies from the midline to the above and below.
Period: the distance between two consecutive maximum points (minimum points).

$505-$115= $390
$390÷$65= 6
6+1= 7
Answer:
135 cm
Step-by-step explanation:
Let Jose's height = x
The mean of their heights = 150
Given the Heights:
150cm, 170cm, 140cm, 155cm
The mean is the sum if the heights divided by the number of people
Here :
(150 + 170 + 140 + 155 + x) / 5 = 150
(615 + x) / 5 = 150
615 + x = 750
x = 750 - 615
x = 135 cm
So you can say that the weight of a koala here can be x.
So x * 1/8 = 2
2 being the chinchilla's weight and the 1/8 coming from the fact that the chinchilla weighs 1/8 of the weight of the koala.
So you can just divide both sides by 1/8 first.
x * 1/8 = 2
/ 1/8 / 1/8
Or,
x *1/8 * 8/1 = 2 * 8/1
x = 16
So the koala weighs 16 pounds.
