Answer:

Option (D) : 1 / 4

Step-by-step explanation:

We know that :

P(A ∩ B) = P(A) * P(B|A)

P(B|A) = P(A ∩ B) / P(A) =  \frac{13}{25}  \times  \frac{20}{13}

P(B|A) =  \frac{4}{5}

Macs farm has a total of 18 horses and 27 cows. what is the ratio of horses to cows in simplest form?
Evgesh-ka [11]
The ratio is basically finding the quotient of two numbers. If you want to find the ratio of horses to cows, divide the number of horses to that of cows.

Ratio = 18/27

When expressing it to its simplest form, make sure it is reduced. 18 and 27 are both factors of 9. So,

Ratio = 9*2/9*3
Cancelling out 9, the ratio at its simplest form is: <em>2/3</em>

How would logx (49) = x look like in exponential form
Ivanshal [37]

I'm assuming the given log equation is \log_{\text{x}}(49) = \text{x}

If so, then the exponential form is \text{x}^{\text{x}} = 49

This is because the general form \log_{\text{b}}(\text{x}) = \text{y} transforms into \text{y} = \text{b}^{\text{x}}

For both equations, the 'b' is the base.
