Aconsumer report counted 72 low quality, 112 medium quality, and 711 high quality computers based on a random sample. the report went on to say that all computers, regardless of quality, are packaged identically and sold at the same price. use the observed frequencies to create a probability model for the quality of the next computer purchased

Step-by-step explanation:

A probability is the number of desired outcomes desired by the number of total outcomes.

I am going to say that we have these following events

L is the event that a computer is low quality.

There are 72+112+711 = 895 computers. Of those, 72 are low quality. So

M is the event that a computer is medium quality.

Of the 895 computers, 112 of them are medium quality. So

H is the event that a computer is medium quality.

Of the 895 computers, 711 of them are medium quality. So

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
