Exponential to log : y=bx

1 answer:

5 0

I believe the equation is as follows:

y=bˣ , if so :

We know that exponential functions are one-to-one. Being one-to-one functions mean they have an inverse, then the inverse of:
<span>y=bˣ is its logarithmic function that is log(b).x=y, where b is the base of the logarithm .Example
</span>
Suppose y=25, the base b=5 & x the number

The exponential form is 5ˣ = 25
& its logarithmic form: x= log₅(25)
The exponential form is equivalent to the logarithmic form:

5ˣ = 25 ==>x= log₅(25)

Answer: 0.23

Step-by-step explanation:

Given : F is the event "works in the finishing department;"

and A is the event "is absent excessively."

Given : 10% of all plant employees work in the finishing department; 20% of all plant employees are absent excessively; and 7% of all plant employees work in the finishing department and are absent excessively.

i.e. P(A)= 0.20 ; P(F)=0.10 ; P(A ∩ F) = 0.07

We know that $P(X\cup Y)=P(X)+P(Y)-P(X\cap Y)$
