A number is selected at random from the set {1,2,3,…,1000}. What is the probability that it is divisible by 19?

the probability is %5.2

Step-by-step explanation:

To know the probability that it is a multiple of 19 we have to know the number of multiples that 19 has between 1 and 1000. And that amount divide it by 1000. Finally we multiply it by 100 and we will have the percentage.

To know how many multiples there are from 1 to 1000 we have to make 1000 divided by 19 and the number that we get the decimals.

1000/19 = 52.63

there are 52 multiples

100*52/1000 = 5.2

the probability is %5.2

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
