Answer:
A
Step-by-step explanation:
easy way to take a note
is that the sum of the 2 first angles much be greater than the 3rd one
so A
Answer:
a. standard deviation
Step-by-step explanation:
Dispersion is a measure of variability in a given data i.e the level or extent of spread of a data. This can easily be measured for a random variable by considering its standard deviation.
The standard deviation would show the extent to which each value is different from the mean. Thus showing the extent of the dispersion of variables.
Therefore, to measure the dispersion of a random variable, look at its standard deviation.
Ratios are simple if you know how. Simply put the two numbers next to each other with a : in between, then simplify.
Therefore, 5 flag stamps to 11 flower stamps has a ratio of 5:11. As both 5 and 11 are prime numbers, they cannot be simplified, so the answer is 5:11<span />
