The <em>correct answer</em> is:
B) precise
Explanation:
Precision can be broken down into two pieces:
<em>Repeatability </em>- The variation observed when the same person measures the same thing repeatedly with the same device.
<em>Reproducibility</em>: The variation observed when different people measure the same thing using the same device.
If two measurements are very close to each other, this gives repeatability. If the measurements were made by different people, this gives reproducibility.
<em>Accuracy</em>, however, describes the difference between the measurement and the thing's actual value. This would not involve getting the same result repeatedly; it would be getting the <em>correct</em> value.
Two million, nine thousand, three hundred forty five.
Answer:
X=30; Z=80; Y=70
Step-by-step explanation:
The straight lines equal 180 and you subtract 180 to 150 and 180 to 100 to get 30 and 80 and the inside of a triangle is 180 and you subtract 30 and 80 to 180 to get 70.
Answer:A)0.27
B)0.78
Step-by-step explanation:
This is the probability of picking 2balls of same color.
P(RR)+Pr(WW)+Pr(BB)
3/10×2/9+4/10× 3/10+3/10 ×2/9=6/90+12/90+6/90=
24/90=4/15=0.27
B)if the first ball is not returned, then there are 9 balls left.
Then probability of same color will be
PrB+PrW+PrR
2/9+3/9+2/9=
7/9=0.78
