The number of quasi-prime numbers that are less than 500 = 92
<h3>What are quasi-prime numbers?</h3>
Quasi-prime numbers are those numbers that are also known as semi prime numbers which can not be divided by 2,7 or 11.
They are often derived from prime numbers which are 95 in number from 2 - 499. ( less than 500).
The 95 prime numbers - 3 numbers( such as 2,7 or 11) = 92
Therefore, the number of quasi-prime numbers that are less than 500 = 92

In this question:
Assignment of 4 employees, from a set of 15. So
Answer: $9.20
Step-by-step explanation:
Divide the full tax price by the sales tax (7% or .07) plus 1 (always add 1 to the tax) thus
$147.66 / 1.07 = $138.00
So $138.00 is the full price without tax.
Now divide $138.00 by the amount of tickets (15) to find a single ticket price before tax!
138.00/15 = $9.20
Remember to always add 1 to the tax percentage above when dividing to get the *pre-tax* price.
6 is 61
5 and 7 are 119 (180 - 61)
4 and 2 are 61
1 and 3 are 119
We are given that
An ion has a charge of +7
and a neutral has charge always 0
so, change is charge = ion charge - neutral change
so, we can plug values
change is charge = +7 -0
change is charge = 7
so, option-C..................Answer
