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:
c
Step-by-step explanation:
because it shows long stable periods
Answer:
c. 198π units²
Step-by-step explanation:
We have to find the surface area of a cylinder.
We know that surface area of a cylinder= 2πrh+2πr²
where r is the radius
and h is the height of the cylinder.
here h=2 units and r=9 units
Surface area= 2π×9×2+2π×9×9
= 198π units²
Hence, correct option is:
c. 198π units²
Maybe 40. I got it by multiplying 8 and 5
Answer:
y = 2sinx + 2
Step-by-step explanation:
∵ y = Asin(Bx - C) + D
∵ D is the vertically shift
∵ It moves 2 units up
∴ D = 2
∴ y = 2sinx + 2
