The two-way table shows the number of people whose hobbies are reading or solving puzzles and who either ride a motorcycle or don’t ride a motorcycle.
among people whose hobby is reading, what is the relative frequency of not riding a motorcycle? express your answer as a decimal, and round to the nearest hundredth if necessary.

The relative frequency of people whose hobby is reading and is not riding a motorcycle is 0.42 (approx)

Step-by-step explanation:

Relative frequency  is the fraction of number of favorable outcome by total possible outcomes that is

Since, we have to find the relative frequency of people whose hobby is reading and is not riding a motorcycle.

From the given data,

Number of people whose hobby is reading  are ( 7 +5) = 12

Number of people whose hobby is reading and is not riding a motorcycle is 5.

(approx)

Thus, the required relative frequency of people whose hobby is reading and is not riding a motorcycle is 0.42 (approx)

the answer is 2/54

step-by-step explanation:

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
