Total number of marbles = 88
Number of red marbles = 25% x 88 = 0.25 x 88 = 22
Answer: There are 22 red marbles in the tin.
Answer:
Both amplitude and coefficient are equal.
Step-by-step explanation:
Given the equation y = 50 sinx. we have to find the relationship between the amplitude of y = 50 sinx and the coefficient 50.
For the curve y = a sin x, the variable 'a' represents the amplitude of graph i.e
Amplitude=|a|
Hence, for the curve y = 50 sinx
Amplitude=|a|=|50|=50
which is equal to the coefficient 50.
Hence, both amplitude and coefficient are equal.

Answer:
65%
Step-by-step explanation:
78/120=13/20
13/20=65/100
65/100=65%
