Answer:

x=-5/13

taking note of the assumption made.

Step-by-step explanation:

(5x-4)+(8x+9)=0

to solve for X, assuming you meant '0' and not '=simply'

we have

5x-4+8x+9=0

group like terms and solve.

5x+8x-4+9=0

13x+5=0

subtracting -5 from both sides of the equation

13x+5-5=0-5;

13x=-5

<u>x=-5/13</u>

In a certain college, 33% of the physics majors belong to ethnic minorities. Of 8 students are selected at random from the physi

Answer: 0.0187

Step-by-step explanation:

The binomial distribution formula for probability :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(x) is the probability of getting success in x trials , n is the total number of trials and p is the probability of getting success in each trial.

Given : The probability that the physics majors belong to ethnic minorities =0.33

Number of students selected : n= 8

Now, the probability that more than 5 belong to an ethnic minority :-

$P(x>5)=P(6)+P(7)+P(8)\\\\=^8C_6(0.33)^6(0.67)^{2}+^8C_7(0.33)^7(0.67)^{1}+^8C_8(0.33)^8(0.67)^{0}\\\\=(\dfrac{8!}{6!2!})(0.33)^6(0.67)^{2}+(8)(0.33)^7(0.67)^{1}+(0.33)^8(0.67)^{0}\\\\=0.0186577086013\approx0.0187$

Hence, the probability that more than 5 belong to an ethnic minority = 0.0187

X + 1 > 3 how many solutions are there?

vagabundo [1.1K]

Answer:

its infinite

Step-by-step explanation:

Given equation is 2x+1=x−3

That is 2x−x=−3−1

⇒x=−4

Thus there is only one point on the number line that satisfies the equation x=−4, but on cartesian plane i.e. X-Y plane , there are infinite number of solutions as x=−4, and y can have any real value.
