Answer:
x=29. Angle C= 93
Step-by-step explanation:
3(x+2)= 3x+6.
3x+6+52+35= 3x+93.
180-93=87.
87/3= 29. So that means x=29.
for proof you can do 3(29)+93 and you'll get 180.
For angle C; 3(29+2)= 3x31. 31x3= 93.
Angle C= 93 degrees.
Well the real answer is three hundred-ninety three point five. So numbers around it could be three hundred and fifty and four hundred. An estimate could be three hundred and seventy five.
The first one is 5
The second one is 200
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Let the 
be the mean amount of time first population ( freshmen) spent studying for the biostatistics final exam.
Let 
be the mean amount of time second population (sophomores) spent studying for the biostatistics final exam.
So, the hypothesis would be
Since, A professor claims that the mean amount of time (in hours) sophomores spent studying for the biostatistics final exam is more than that of freshmen.
So, alternate hypothesis becomes:
Hence, Option 'D' is correct.
