Lisa's drawing has the following dimensions:
Width=43.5 cm
Length=934 mm
but 1 cm =10 mm
thus
934mm when converted into cm we shall have:
length=93.4 cm
To get the total length of material required to frame the picture, we calculate the perimeter.
P=2(L+W)
P=2(93.4+43.5) cm
P=2(136.9)
P=273.8 cm
The total length of material required will be 273.8 cm
Answer: The friend won the round.
Step-by-step explanation:
We want to find the lowest score.
The lowest score means the smallest value.
With intergers, as the number gets farther away from zero to the left, the smaller the value is. The middle number is zero on a number line. The numbers to the left of zero are negative. The number to the write of zero are positive.
As you move to the left on the number line, the numbers get smaller. As you move to the right on a number line, the values get bigger
Since -4 is farther away from zero to the left on a number line than -3, -4 is smaller.
Hence -4 is smaller than -3. -4 is one more to the left than -3 so -4 is smaller than -3.
Hence the friend won the round.
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.
