Answer:
we expect the results to have less spread
Step-by-step explanation:
The spread between the maximum and minimum is almost 1/3 of the average of those values (0.8 vs 2.6). We expect repeated measurements of the same physical value to be well within 5% of their mean if they are done carefully.
The investigation has errors because the spread is too great.
I believe the correct answer is B
Answer:
Step-by-step explanation:
STEP 1: <em>Rewrite the equation as 3
n
+
6
p
=
15
.</em>
STEP 2: <em>Subtract 6
p from both sides of the equation.</em>
STEP 3: <em>Divide each term by 3 and simplify.</em>
The value of y will probably be 4.
The circumference of the larger circle is about 12.57 inches. The circumference of the smaller circle is about 3.14 inches. So, the total length of gold leaf on a tag is approximately 15.71 inches.
<h3>How to illustrate the circle?</h3>
The circumference will be:
= 2πr
= 2 × 3.14 × 2
= 12.57 inches.
The circumference of the smaller circle will be:
= 2πr
= 2 × 3.14 × 0.5
= 3.14
The total length will be:
= 12.57 + 3.14
= 15.71 inches.
