Step-by-step explanation:
Accuracy is the closeness of a measured value to a standard value.
Precision is the closeness of two or more measurements to each other.
1.The norm is 45 sit-ups in a minute.The students did, 64, 69,65 and 67. Values are not accurate compared to standard value 45.
Values are precise
Answer--Precise
2. Average score is 89.5
Scores are 89,93,91,87
Values are precise i.e a difference of 2 from each score
Values are accurate because the average score is 90 thus compared to the known average score of 89.5 they are accurate.
Answer-Both
3. Yesterday temperature=89
Tomorrow=88
Next day=90
Average =75
Values are precise i.e. difference of ± 1°
Values are not accurate compared to the average temperatures of 75 F

Answer:
She could divide 9.42 by Pi to find the radius, then multiply 9.42 by the radius.
(Last option)
Step-by-step explanation:
We need the formula for the area of a circle:
A = πr²
Remember r² = r × r
So you could rewrite the formula like this:
A = π × r × r
If π × r = 9.42, then the area becomes:
A = 9.42 × r
"<em>Then multiply 9.42 by the radius</em>".
To find "r", divide 9.42 by π.
π × r = 9.42
r = 9.42/π
"<em>Divide 9.42 by Pi to find the radius</em>".
Answer:
A
Step-by-step explanation: Well 15:30 I would think is just 1:2 so looking for another ratio like that there's only one other answer. 3:6 15 is half of 30 and 3 is half of 6.
16 = 2/3f
16 ÷ 2/3 = f
16 × 3/2 = f
48/2 = f
24 = f
