48 degrees, anything opposite of a degree on the same 2 infinite lines will always be the degree.
f(x) = x² + 2
y = x² + 2
x = y² + 2
x - 2 = y²
√(x - 2) = y
√(x - 2) = f⁻¹(x)
Answer:
a) 4.33 (three repeating)
b) 3.5
c) 3
d) 0.44
Step-by-step explanation: Mean is all the numbers added up and divided by the amount of items. All the items added together are 78. We have 18 items 78/18 = 4.3 (three repeating). Median is just the middle value. This is between 3 and 4 so 3.5. Mode is the one that shows the most. This is 3. 8 students play games for more than 4 hours. 8/18 = 0.44
It could represent Range or domain
