The first thing you should do is to<span> divide the total cost by the unit cost you have got: </span><span>(2y^2 + 6) / (y^2 - 1) </span>
Then just use simple math by plugging in the value y=3
(2*3²+6): (3²-1)=  24:8 = 3 which is the nubmer of the bought notebooks. 

<span>In total he spent $24 on notebooks that cost $8.</span>

Count by five from 135 to 175 .write these numbers and describe the pattern
melomori [17]
<span>Count by five from 135 to 175 means you will increase the number by 5 each time.
The pattern will be as follows:
135
135 + 5 = 140
140 + 5 = 145
</span>145 + 5 = 150
150 + 5 = 155
155 + 5 = 160
160 + 5 = 165
165 + 5 = 170
170 + 5 = 175

The pattern is n+5 where n is the previous number in the pattern.

Companies use employee training for various reasons, including employee loyalty, certification, quality, and process improvement
Radda [10]

Answer:

0.3081 = 30.81% probability that the company uses training for employee retention and not for process improvement

Step-by-step explanation:

56% employee retention.

38% for process improvement. Of those, 89% for employee retention.

a. What is the probability that the company uses training for employee retention and not for process improvement

The 56% is composed by:

x of 100 - 38 = 72%(not for process improvement)

89% of 38%(for process improvement).

We want to find x. So

0.72x + 0.89*0.38 = 0.56

0.72x = 0.56 - 0.89*0.38

x = \frac{0.56 - 0.89*0.38}{0.72}

x = 0.3081

0.3081 = 30.81% probability that the company uses training for employee retention and not for process improvement
