If x is the number of students on the field trip:
60 + 15x + 95 + 12x
Supplementary means they add up to 180°.
180-112= 68
The answer is 68°
Answer:
8 16
Step-by-step explanation:
3/16+5+16=8/16
16/16(the whole mug)-8/16=8/16
At 95% confidence interval, true population mean is given by
x+/- 2sd
where x= sample mean and sd = sample standard deviation
True mean of population = 13.50 +/- 2*1.51 = 13.50+/-3.02
Interval: 13.50+3.02, 13.50-3.02 = 16.51, 10.48
