Answer:
Step-by-step explanation:
If we choose chairs having odd number in the row
no of chairs from which selection is made = 10
no of chairs to be selected = 5
no of ways = 10C₅
similarly if we choose hairs having even numbers only ,
similar to above , no of ways
= 10C₅
Total no of ways
= 2 x 10C₅
= 2 x 10 x 9 x 8 x 7 x 6 / 5 x 4x3 x 2 x 1
= 504 .
Answer:
A
Total before tax: $118
Total after tax: $102.66
Step-by-step explanation:
For A, we add the cost of the shirt and jeans to get the total before tax.
$39.20 + $79.80 = $118.00
For the total, after 13% we see how much 1% is.
1% of $118 is $1.18
$1.18 * 13 = $15.34.
$118 - $15.34 = $102.66
Hope this helped! Have a nice day :)
2+(-3) = -1
2- 3 = -1
-1=-1
The question is why though ?
It is because you keep the negative exponent which is with the biggest number. So this is how its look like +2 -3, so 3 is bigger then 2 so for that reason you keep the negative sign.
I hope that's help:)
