So you have 20% of blue and 50% of black.
So you have 70% in total that are both blue and black.
100%- 70%= 30%
So that means 30% were neither blue or black.
Do a proportion
30/100= x/30
30 x 30= 900
900 divided by 100= 9
Answer is 9 shirts are neither blue or black
Groups of four for the group of 288 and groups of five for the group of 360
Answer
C) -8
Step-by-step explanation:
Im assuming the base of the triangle is 4cm. The volume is

.
If the dimensions are tripled, the base is 12, the height is 24, and the length is 18. The volume is

, which is 27 times bigger.
If you are increasing each side by a factor of x, you are multiplying the original by
The function f(x)=4sin(2πx) is a sinusoidal function
The graph of the function f(x)=4sin(2πx) is graph (c)
<h3>How to determine the graph of the function f(x)=4sin(2πx)?</h3>
The parent function of a sine function is
f(x) = sin(x)
The function f(x)=4sin(2πx) implies that the parent function f(x) = sin(x) has been horizontally and vertically stretched
So, the graph of the function f(x)=4sin(2πx) would have a higher amplitude and shorter period than its parent function
Hence, the graph of the function f(x)=4sin(2πx) is graph (c)
