A research company found that 11% of the people that they called agreed to participate in a survey.
goldfiish [28.3K]

Answer:

22 people would be expected to participate in the survey.

Step-by-step explanation:

We are given that a research company found that 11% of the people that they called agreed to participate in a survey.

The company called 196 people and we have to find that how many would be expected to participate in the survey.

The above situation can be represented through binomial distribution;

P(X=r)=\binom{n}{r} \times p^{r}\times (1-p)^{n-r}; x = 0,1,2,3,.....

where, n = number of trials (samples) taken = 196 people

            r = number of success

            p = probability of success which in our question is probability

                   that people agreed to participate in a survey, i.e; p = 11%

Let X = <em><u>Number of people who agreed to participate in a survey</u></em>

SO, X ~ Binom(n = 196, p = 0.11)

Now, the expected number of people who would participate in the survey is given by;

                   E(X)  =  n \times p  

                            =  196 \times 0.11  = 21.56 ≈ <u>22 people</u>

<u></u>

Hence, 22 people would be expected to participate in the survey.

What is the solution? 4p – 12 = 8 + 4p + 5p<br> a. 16<br> b. 6<br> c. -5<br> d. -4
ira [324]

Answer:

d. -4

Step-by-step explanation:

  • 4p – 12 = 8 + 4p + 5p
  • 4p – 12 = 8 + 9p
  • 4p – 9p = 8 + 12
  • – 5p = 20
  • p = 20 ÷ (– 5)
  • p = – 4

Two old RSM students were standing ten feet apart when they ran in opposite directions with speeds of 180 feet per minute and 16
inessss [21]

The number of minutes that would pass before they were 1870 feet apart is 5.47 minutes

  • Since one student runs at a speed of 180 feet per minutes, in time t minutes, he moves a distance of d = 180t.
  • Also, the second student runs at a speed of 160 feet per minute, in time t minutes, he moves a distance of d' = 160t.

Since they are initially 10 feet apart, their total distance apart after t minutes is D = d + 10 + d'

D = 180t + 10 + 160t

D = 340t + 10

<h3>Number of minutes before they are 1870 feet</h3>

Making t subject of the formula, we have

t = (D - 10)/340

Since they are 1870 feet apart after t minutes, D = 1870 feet.

t = (D - 10)/340

t = (1870 - 10)/340

t = 1860/340

t = 5.47 minutes

So, the number of minutes that would pass before they were 1870 feet apart is 5.47 minutes
