Suppose the probability of being in honors math is 0.30 and the probability of being in honors math and honors science is 0.20.
kaheart [24]

Answer:

Option C) 0.67

Step-by-step explanation:

We are given the following in the question:

M: Maths honors

S: Science honors

Probability of being in honors math = 0.30

P(M) = 0.30

Probability of being in honors math and honors science = 0.20

P(M\cap S) = 0.20

We have to find the probability of being in honors science if you are in honors math.

We have to evaluate:

P(S|M) = \dfrac{P(M\cap S)}{P(M)} = \dfrac{0.20}{0.30} = 0.67

Thus, 0.67 is the probability of being in honors science if you are in honors math.

Thus, the correct answer is

Option C) 0.67

Hi,
To find K you will pick a value from the x and then the corresponding Y value. Then we will plug it into the equation that is given y=Kx

Here:
X=25 Y=160
160=k25
(Divide both sides by 25 to isolate K)
K=6.5

Then plug K value into equation
Y=6.5X

Then if you want to check if that is correct you can pick a different point on the table and plug that into the equation to see if you get the same value.

Check:
X=50

Y=6.5x50
Y=320

find the formula for a rational function that satisfies all of the following. its x-intercept is (-3,0). it has a vertical asymp
Norma-Jean [14]

Let that be

\\ \rm\Rightarrow y=\dfrac{a(f(x))}{g(x)}

Two vertical asymptotes at -1 and 0

\\ \rm\Rightarrow y=\dfrac{a(f(x)}{x(x+1)}

If we simply

\\ \rm\Rightarrow y=\dfrac{a(f(x)}{x^2+1}

  • Denominator has degree 2
  • Numerator should have degree as 2 and coefficient as 3 inorder to get horizontal asymptote y=3 means the quadratic equation should contain 3x²
  • But there should be a x intercept at -3 so one zeros should be -3

Find a equation

  • 3x²+9x

Find zeros

  • 3x²+9x=0
  • 3x(x+3)=0
  • x=0,-3

Horizontal asymptote

  • 3x²/x²
  • 3

So our equation is

\\ \rm\Rightarrow y=\dfrac{3x^2+9x}{x(x+1)}
