5x=(2x-2)(m+6)<br> Solve for x

coldgirl [10]

Answer:

Step-by-step explanation:

hello :

5x=(2x-2)(m+6) equivalent : 5x = 2xm+12x-2m-12

5x-2xm -12x=-2m-12

x(5-2m-12) = -2m-12

x(-7-2m) = -2m-12

x(2m+7) = 2m+12

if : 2m+7 ≠ 0 means m ≠ -7/2 so : x= (2m+12)/(2m+7)

if : 2m+7 = 0 means : m = -7/2 you have : x(0) = 2(-7/2)+12

0= 5 ( false) ... x no exist

Answer:

0.2060 = 20.60% probability that 2 or fewer will withdraw

Step-by-step explanation:

For each student, there are only two possible outcomes. Either they withdraw, or they do not. The probability of a student withdrawing is independent from other students. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

20% of its students withdraw without completing the introductory statistics course.

This means that $p = 0.2$

Assume that 20 students registered for the course.

This means that $n = 20$

Compute the probability that 2 or fewer will withdraw (to 4 decimals).

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{20,0}.(0.2)^{0}.(0.8)^{20} = 0.0115$

$P(X = 1) = C_{20,1}.(0.2)^{1}.(0.8)^{19} = 0.0576$

$P(X = 2) = C_{20,2}.(0.2)^{2}.(0.8)^{18} = 0.1369$

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0115 + 0.0576 + 0.1369 = 0.2060$

0.2060 = 20.60% probability that 2 or fewer will withdraw
