Solve the compound inequality n-4 > 5 AND 2 > n + 3
Papessa [141]
Get n by itself in both inequalities

(This program doesn't allow for regular less than or greater than signs, so for the purposes of this problem I will be using less than or equal to (≤) and greater than or equal to (≥) signs)

Inequality 1:
n-4   \geq 5 \\ n \geq 9

Inequality 2:
2 \geq n+3 \\ -1 \geq n

Now that you have both of the n's by themselves, you can put the two inequalities together, like this
-1 \geq n \geq 9

Just keep in mind that these are supposed to be regular less than signs

Suppose a normal distribution has a mean of 38 and a standard deviation of 2. What is the probability that a data value is betwe
Dimas [21]

Answer:

P ( 37 < x < 41) = P(-0.5 < Z < 1.5) =  0.6247

Step-by-step explanation:

We know mean u = 38  standard dev. s = 2

We want  P ( 37 < x < 41)

so

P( (37 - 38) / 2 <  Z) =  P(-0.5 < Z)  

P( Z <  (41 - 38)/2 ) =  P( Z < 1.5)

Find  P(Z < -0.5) = 0.3085

Find P(Z > 1.5) = 0.0668

so  P(-0.5 < Z < 1.5) =  1  - P(Z < -0.5) - P(Z > 1.5)

P(-0.5 < Z < 1.5) =  1  - 0.3085 -  0.0668

P(-0.5 < Z < 1.5) =  0.6247

P ( 37 < x < 41) = P(-0.5 < Z < 1.5) =  0.6247

How to evaluate F/G(x) if f(x)=x²-2x , g(x) = x+9​
tiny-mole [99]

Answer:

f/g\textrm{ }(x)=\frac{x^{2}-2x}{x+9}

Step-by-step explanation:

Given:

f(x)=x^{2}-2x, g(x)=x+9

f/g\textrm{ }(x) is nothing but dividing f(x) by g(x)

Therefore, f/g\textrm{ }(x) is given as:

f/g\textrm{ }(x)=\frac{f(x)}{g(x)}\\f/g(x)=\frac{x^{2}-2x}{x+9}
