Hence the 95% confidence interval for the number of chocolate chips per cookie for big chip cookies= (10.1989,\ 11.0011)(10.1989, 11.0011)
Answer:
(7w - k)(4x + y)
Step-by-step explanation:
Factor by grouping is best for this expression. To factor by grouping, group pairs of terms with parenthesis. Then find the GCF in each pair. If the parenthesis match after, the factoring is complete.
28xw + 7wy - 4kx - ky
(28xw + 7wy) + (- 4kx - ky)
7w(4x + y) - k (4x + y)
The factors are (7w - k)(4x + y).
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.
