Answer:
b=1/2
Step-by-step explanation:
2logb - 3logb = log8b - log4b
log - log
= log8b - log4b
log() = log(2)
∴1/b = 2
∴b = 1/2
By 32,760 different ways can a researcher select 4 rats from 15 rats and assign each to a different test .
<u>Step-by-step explanation:</u>
We need to find How many different ways can a researcher select 4 rats from 15 rats and assign each to a different test.Let's find out:
We will use Permutation here : As we will chose 4 rats out of 15 rats , order will be considered which will make this as a permutation problem . Formula for permutation is given by :
⇒
According to question , we have

Therefore , By 32,760 different ways can a researcher select 4 rats from 15 rats and assign each to a different test .
Answer:
Step-by-step explanation:
slope-intercept form: y = mx + b
y = (x , y)
m = slope =
x = (x , y)
b = y-intercept =
With this given information, your slope will be
