4 .c is the right answer
Step-by-step explanation:
16=100%
20÷16=1.25 or 125%
125%-100%= 25% increase
X + y = 24
x - y = 2
Adding both equations
2x = 26
x = 13
y = 11
Answer:
6.5
Step-by-step explanation:
5.1+7.9=13
13 divided by 2
= 6.5
Step-by-step explanation:
The period of f(x) is π.
To calculate the period using the formula derived from the basic sine and cosine equations. The period for function y = A sin (B a – c) and y = A cos ( B a – c ) is equal to 2πB radians. The reciprocal of the period of a function is equal to its frequency.
Number of tables al four restaurants have;
= 4 * 30
=120 tables
Two new restaurants + 4
=6 restaurants
(120+15+9)= 144 tables
Mean = total # of tables/ total # of restaurants;
144/6
=24
This is the mean so it decreases. I hope this helps even though you didn’t actually post the number line
