Answer:
Unit rate is often a useful means for comparing ratios and their associated rates when measured in different units. The unit rate allows us to compare varying sizes of quantities by examining the number of units of one quantity per one unit of the second quantity. This value of the ratio is the unit rate.

Answer:
What is the probability both are math phobic? 0.49%
What is the probability at least one is math phobic? 9.31%
Step-by-step explanation:
In order to both be math phobic, both individuals has to be inside of the probability of 7%, that means 0.07*0.07 = 0.0049 = 0.49%
In order to at least one be math phobic there's some cases which satisfies the sentence:
Individual A is math phobic and B as well = 0.07*0.07 = 0.0049 = 0.49%
Individual A is math phobic, but B is not = 0.07*0.63 = 0.0441 = 4.41%
Individual A is not, but B is math phobic = 0.63*0.07 = 0.0441 = 4.41%
Suming the 3 possibles cases, the probability at least one is math phobic
= 9.31%

b) Blue color had an experimental probability that matched its theoretical probability.
Explanation:
Since we have given that
Number of times this spinner is spinned = 60
Number of times black occur = 17
Number of times blue occur = 15
Number of times orange occur = 21
Number of times purple occur = 7
a) So, Experimental probability of a spin of orange is given by

b) which color had an experimental probability that matched its theoretical probability.
According to theoretical probability ,
Every event must have equal probability, i.e. 
And,

So, Blue color had an experimental probability that matched its theoretical probability.
