1. Refer to the equation 2x − 6y = 12. (a) Create a table of values for at least 4 points. Show your work.
Sergio039 [100]
2x - 6y = 12

so we pick any number for x and then solve for y

lets say x = 0
2(0) - 6y = 12
-6y = 12
y = -12/6
y = -2....so when x = 0, y = -2....(0,-2) <== one point

lets say x = 1
2(1) - 6x = 12
2 - 6x = 12
-6x = 12 - 2
-6x = 10
x = -10/6
x = - 5/3...so when x = 1, y = -5/3....(1,-5/3) <== another point

Lets say x = 2
2(2) - 6y = 12
4 - 6y = 12
-6y = 12 - 4
-6y = 8
y = -8/6
y = - 4/3....so when x = 2, y = -4/3.....(2,-4/3) <== another point

lets say x = 3
2(3) - 6y = 12
6 - 6y = 12
-6y = 12 - 6
-6y = 6
y = -6/6
y = -1....so when x = 3, y = -1.....(3,-1) <== another point

now there is 4 points.

A banks loan officer rates applicants for credit. The ratings are normally distributed with a mean of 200 and a standard deviati
Alona [7]

Answer:

2.87%

Step-by-step explanation:

We have the following information:

mean (m) = 200

standard deviation (sd) = 50

sample size = n = 40

the probability that their mean is above 21.5 is determined as follows:

P (x> 21.5) = P [(x - m) / (sd / n ^ (1/2))> (21.5 - 200) / (50/40 ^ (1/2))]

P (x> 21.5) = P (z> -22.57)

this value is very strange, therefore I suggest that it is not 21.5 but 215, therefore it would be:

P (x> 215) = P [(x - m) / (sd / n ^ (1/2))> (215 - 200) / (50/40 ^ (1/2))]

P (x> 215) = P (z> 1.897)

P (x> 215) = 1 - P (z <1.897)

We look for this value in the attached table of z and we have to:

P (x> 215) = 1 - 0.9713 (attached table)

P (x> 215) =.0287

Therefore the probability is approximately 2.87%

Help help help it is simple one​
algol [13]

Answer:

3^{ -x+3}

Step-by-step explanation:

We need to simplify out the given exponential expression . The given expression to us is ,

\rm\implies \dfrac{\dfrac{1}{3}}{3^{x-4}}

We can use the <u>Law of </u><u>Exponents</u> to simplify the given expression . Recall that ,

\rm\implies \red{\dfrac{a^m}{a^n}= a^{m-n}}

Note that , we can write ,

\rm\implies \dfrac{1}{3}= 3^{-1}

Therefore our expression becomes ,

\rm\implies \dfrac{ 3^{-1}}{3^{x-4}}

Simpify using the Law of Exponents ,

\rm\implies 3^{ -1 - ( x - 4 )}

Open the brackets in exponent ,

\rm\implies 3^{ -1 - x +4 }

Simplify to get final expression ,

\rm\implies \boxed{\quad \blue{ 3^{-x+3} \quad}}
