What are the values of a and b in the relative frequency table for the survey results? Round answers to the nearest percent. a = 12%, b = 17% a = 12%, b = 18% a = 40%, b = 18% a = 41%, b = 63%

The data that we have is:

Carrots = 84

Turnips = 25

Both = 17

Neither = 15

Root vegetables = 84 + 25 - 17 + 15 = 107

"a" is the percentage of carrots that also are turnips.

we know that 17 carrots are also turnips. so the relative frequency is:

17/107 = 0.158, in percent form this can be rounded to 16%.

b is the number of NOT carrots, that also are turnips.

This will be equal to the 25 turnips minus the 17 turnips that also are carrots

25 - 17 = 8

So we have 8 turnips that are not carrots.

Then we have:

b = 8/107 = 0.075

rounded to the nearest percent we get b = 8%.

So the values do not coincide with the options, and neither some of the data, for example the carrots that are not turnips are:

84 total carots, 17 of them are turnips, so we have 84 - 17 carrots that are not turnips:

84 - 17 = 67

then the relative frequency is:

P = 67/107 = 0.626, rounded to the nearest percent we get 63%

So there may be a number wrong in the diagram.

in english this is

ex.15 pag.85 create. write in ten lines the continuation of the ballad of the five motanasi, using verbs to the imperfect and to the perfect compound. five stars

hope i with whatever it is that you need! : )

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
