Experimental probability is doing a test and basing probability on that.
Like if you roll a dice 100 times and 6 comes up 21 times, the
experimental probability is 21%.
1. 2x - (3x + 6).....negative before parentheses makes everything inside parentheses opposite
2. 2x - 3x - 6....2x - 3x = -1x
3. -1x - 6
Answer:
-1x - 6
The linear function representing the above function is
F=0.4x+2
Step-by-step explanation:
Let the total monthly cost be represented as $ F
Let the number of songs downloaded in a month be x
Given: cost of downloading one song= $ 0.40
Monthly subscription fee (one time monthly) = $ 2
Hence total monthly cost-
Total monthly cost= cost of downloading “x” songs + monthly subscription fee
Total cost of downloading “x” songs monthly= number of songs downloaded* cost of downloading one song
Total cost of downloading “x” songs monthly=$ 0.4x
Hence Total monthly cost= 0.4x + 2
We have assumed total monthly cost as “F”
F=0.4x+2
