Intersection means elements both have. Both sets have -1 but they have nothing else in common so the intersection is {-1}
Union means combining the sets so {-1, 1, 2, 3, 7} Note that I only wrote 1 twice. No duplicates allowed!
<span>Average speed = distance over time so here
Speed = (22 1/2) / (1/3) = 67 1/2 miles per hour</span>
The equations to represent the relationship are ƒx3/5=4 4/5 and 4 4/5 divided 3/5 =f
<h3>Ratio and proportion</h3>
Fractions are written as a ratio of two integers. For instance a/b is a fraction.
If Anastacio distributed 4 4/5 kg of seed among several bird feeders and put 3/5 kg of seed in each feeder, the expression that represents the number of bird feeders that Anastacio filled is given as;
Number of bird feeder = 4 4/5 ÷ 3/5
f = 4 4/5 ÷ 3/5
Multiply both sides by
f * 3/5 = 4 4/5 ÷ 3/5 * 3/5
f * 3/5 = 4 4/5
Hence the equations to represent the relationship are ƒx3/5=4 4/5 and 4 4/5 divided 3/5 =f

Step-by-step explanation:
The age of the skull can be found using carbon-14 by applying the half-life relationship.
Age of skull is given by;

where N=63 N₀=100 -0.693=decay factor of carbon and 5730 =half-life of carbon-14, t =age
substitute values in equation
