Answer:
x=44
Step-by-step explanation:
33+103+x=180
136+x=180
x=44
Answer:
- The term observed frequencies are found in the sample.
Hence, option 'd' is correct.
Step-by-step explanation:
Unlike the expected frequency which is obtained based on prediction, the observed frequency is the actual frequency that is determined from the experiment.
Therefore, we conclude that
- The term observed frequencies are found in the sample.
Hence, option 'd' is correct.
The answer would have to be A because if it's ROUNDED to the nearest ounce then 2 is closer to 0 so it would be A
Complete question :
Sam knows that his MP3 player has 40% of its battery life left and that the battery
charges by an additional 12 percentage points every 15 minutes. What percent of
the mp3's battery will be charged when Sam and his family leave? If mp3 was plugged in an hour before his family plan to leave.
Answer:
88%
Step-by-step explanation:
Time before leaving = 1hour
Current percentage = 40%
Charge rate = 12% every 15 minutes
Therefore,
Charge rate per minute :
12% / 15 = 0.8% per minute
Charge recieved after one hour (60 minutes) :
0.8% * 60
= 48%
Therefore, total charge after just before leaving is:
Current percentage + percentage received
40% + 48%
= 88%
Multiply the equations to get the coefficients Greatest Common Factor:
3(2x+4y=11)
2(3x+6y=17)
6x+12y=33
6x+12y=34
Then you subtract them:
0x+0y=-1 0=-1
Or in other words no solutions
