The coordinates of the vertices of AJKL are J(-5, -1), K(0, 1), and L(2, -5).

dalvyx [7]

We need slope of all lines ?

J(-5,-1)
K(0,1)
L(2,-5)

Slope of JK:-

$\\ \sf\longmapsto m=\dfrac{1+1}{0+5}=\dfrac{2}{5}$

Slope of KL:-

$\\ \sf\longmapsto m=\dfrac{-5-1}{2-0}=\dfrac{-6}{0}=-3$

Slope of JL

$\\ \sf\longmapsto m=\dfrac{-5-1}{2+5}=\dfrac{-6}{7}$

There are 30 balls numbered 1-30 in a bag. One is randomly selected 12 times. What is the probability of getting a prime number

Sliva [168]

Answer: The probability of getting a prime number exactly five times = 0.1908

Step-by-step explanation:

Prime numbers from 1 to 30 are 2,3,5,7,11, 13, 17, 19, 23, 29.

The probability of getting a prime number p= $\dfrac{10}{30}=\dfrac13$

Number of trials n = 12

Binomial probability formula:

$P(X=x) = \ ^nC_x p^x(1-p)^{n-x}$

, where x= number of successes

n= number of trials.

x = Number of successes

p= probability of getting one success.

The probability of getting a prime number exactly five times:

$P(X=5)=\ ^{12}C_5(\frac13)^5(1-\frac13)^{7}$

$=\frac{12!}{5!7!}(\frac1{243})(\frac{128}{2187})\\\\=0.1908$

Hence, the probability of getting a prime number exactly five times = 0.1908

In 1978, the amount of earnings required to earn one Social Security credit was $250. Thirty years later, in 2008, this amount w

vagabundo [1.1K]

Answer:

the percentage increase is 360%

Step-by-step explanation:

The computation of the increase in percentage is shown below;

Given that

SOcial security credit as on 1978 is $250

And, the social security tax as on 2008 is $1,150

Now based on the above information

The percentage increase is

= ($1,150 - $250) ÷ ($250)

= 360%

Hence, the percentage increase is 360%
