Blank equals 2 because 543-2=541
Accuracy refers to how close the values are to the true result.
Precision refers to how close the values are to each other.
The above example shows that on Sunday, the reading of thermometer was 6 degrees from the actual reading and on the next 4 days the reading was 2 to 5 degrees from the actual reading. Since the measurements are being compared to the actual result and not to each other, the example gives the instant of Accuracy only, not the precision.
So, the answer to this question is option A
Answer:x = - 5
y = 2
Step-by-step explanation:
The given system of simultaneous equations is expressed as
x + 3y = 1 - - - - - - - - - - - - - -1
4x + 4y = -12 - - - - - - - - - - - 2
We want to eliminate x. Multiplying equation 1 by 4 and equation 2 by 1, it becomes
4x + 12y = 4
4x + 4y = - 12
Subtracting the second equation from the first equation, it becomes
8y = 16
y = 16/8 = 2
Substituting y = 2 into equation 1, it becomes
x + 3 × 2 = 1
x + 6 = 1
x = 1 - 6 = - 5
Hi there!
πd = Circumference of th' circle
![\dfrac {22}{7}](https://tex.z-dn.net/?f=%5Cdfrac%20%7B22%7D%7B7%7D)
× d = 15 ft
d = 15 ×
![\dfrac {7}{22}](https://tex.z-dn.net/?f=%5Cdfrac%20%7B7%7D%7B22%7D)
d =
![\dfrac {105}{22}](https://tex.z-dn.net/?f=%5Cdfrac%20%7B105%7D%7B22%7D)
d = 4. 77
Hence, the required dia-meter = 4. 77
