. the sum of the firs n term is:
the nearest integer would be:
292
AFTER 25%
oriignal=100%
discount of 25% means minus 25%
100%-25%=75%
therefor
180=75% of original

240=original
$240
There’s 4 jacks and 4 aces in a deck of cards so the probability would be 8:52 i think
Answer:
-10² = -100
Step-by-step explanation:
The error in the evaluation occurred when the negative base (which is -10) was squared altogether outside of the parenthesis. (-10²) still results in <u>-100</u>.
The only time that the result will produce a positive 100 is when you square -10 this way: (-10)² = 100 because the negative sign is included with the squaring of base through the parenthesis.
Hope this helps.
