Answer:
5^4
Step-by-step explanation:
because 5 is multiplied 4 times
The price of the sweater was reduced by 40%
Step-by-step explanation:
Step 1; Cost before reduction was $20. The cost after reduction was 12$. Cost reduced= cost before reduction - cost after reduction
Cost reduced= $20 - $12 = $8
Step 2; We must find how much of the cost was reduced from the initial cost i.e. how much $8 is to $20. To do this we must convert it into a percentage. We divide the $8 with the $20 to get a value. This value must be multiplied with a 100 to be converted into a percentage.
Cost by which sweater was reduced=
* 100 = 0.4 * 100 = 40
So the price of the sweater was reduced from $20 to $8 which equates to a reduction in 40%.
yo i dont know the answer but i hope you have a good day
Answer:
The last choice: log 25 Over log 8
Step-by-step explanation:
Because the change of base formula says:
log (subscript 8) of 25 = log (25) / log (8)
let log be the Common Log without subscripts
Answer:
C. 19.23%
Step-by-step explanation:
We simply have to sum up all the times he had a six then divide that by all the times he rolled the die.
Total times he got 6: 5 + 3 + 11 + 11 = 30
Total times he rolled the die: 39 + 21 + 55 + 41 = 156
The experimental probability is then 30 / 156 = 19.23%
It's a bit higher than expected (1/6 or 16.66%), but the sampling is relatively small. If he were to throw it a thousand times, he'd probably be much close to the theoretical probability.
