Answer:
more than 10 months
Step-by-step explanation:
Alex's balance starts at 720 and increases by 80 each month. It can be represented by ...
A = 720 +80m
Jax's balance starts at 480 and increases by 120 each month. It can be represented by ...
J = 480 +120m
Jax's balance will be more than 160 more than Alex's when ...
J -A > 160
(480 +120m) -(720 +80m) > 160
40m -240 > 160 . . . . . . . . . . . . . collect terms
m -6 > 4 . . . . . . . . . . . . . . . divide by 40
m > 10 . . . . . . . . . . . . add 6
It will take more than 10 months for Jax to have saved over $160 more than Alex.
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 .
