Hyp^2 = a^2 + b^2
sqrt (hyp) = 2
hyp = 4
hyp^2 = 16 then from above a^2 + b^2 = 16
Answer: 
Step-by-step explanation:
Given
Sample of 12 measurements has a mean of 16.5 and
a sample of 15 measurements has a mean of 18.6
Take 
be the mean and no of measurements
and 
be the mean and no of measurements in second case
Similarly,
Mean of 27 measurements
Answer:
1. m=2x b=1 2. m=5/8x b= -1 3. m=7/8x b= -3/4 4. m=3/4x b=4
Step-by-step explanation:
Answer: -7
Step-by-step explanation:
The equation is in slope-intercept form (y=mx+b), where m is the slope and b is the y-intercept
Therefore, the m value is -7 and it is the slope
T < 5/2
t is less than 5/2 or 2.5
