Problem 7.7 (large population sampling). We know that 5% of the people in a certain population have a virus. Suppose that I draw a random sample of 100 individuals: the population is so large (in the order of millions) so that, even though I perform the sampling without replacement, my samples may be considered independent of one another (that is, (i) the first and second individuals having the virus are independent events, and (ii) regardless of the first individual, the probability of picking another individual with the virus is still 5%). Let N be the random variable describing the number of individuals, in my sample, with the virus. (a) What is the probability distribution of N

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17

step-by-step explanation:

mark brainliest and have a great day!

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
