Answer:
x=8,9
Step-by-step explanation:
x^2-17x+72=0
(x-8)(x-9)=0
x=8,9
Out of the weekly amount that Shashi Rimoko makes, a deduction of $37.93 is made for insurance.
The total Medical cost is $9,560 and out of this, the amount paid by Shashi per year is:
<em>= Amount x (1 - percentage paid by restaurant)</em>
= 9,560 x ( 1 - 80%)
= $1,912
The amount he pays for Dental coverage is:
<em>= Amount x (1 - percentage paid by restaurant)</em>
= 172 x (1 - 65%)
= $60.20
The total amount he pays for insurance per year is:
<em>= Medical + Dental </em>
= 1,912 + 60.20
= $1,972.20
The weekly deduction is:
<em>= Year amount / No. of weeks in year </em>
= 1,972.20 / 52
= $37.93
In conclusion, $37.93 is deducted from his paycheck every week.

83 + 94 + 79 + 97 + 96 + 87 = 536.
536 ÷ 6 = 89.333333...
So, Lamonts' average is under 90.
A. C(13, 10) = 13! = 13·12·11 = 13 · 2 · 11 = 286.C(13, 10) = 13! = 13·12·11 = 13 · 2 · 11 = 286.
B. P(13,10)= 13! =13! =13·12·11·10·9·8·7·6·5·4.
(13−10)! 3!
C. f there is exactly one woman chosen, this is possible in C(10, 9)C(3, 1) =
10! 3!
9!1! 1!2!
10! 3!
8!2! 2!1!
10! 3!
7!3! 3!0!
= 10 · 3 = 30 ways; two women chosen — in C(10,8)C(3,2) =
= 45·3 = 135 ways; three women chosen — in C(10, 7)C(3, 3) =
= 10·9·8 ·1 = 120 ways. Altogether there are 30+135+120 = 285
