This is a result of the rules of significant figures. These are the digits of the numbers that matter. For operations involving multiplication, the product should have the same significant numbers with the least significant numbers of the given data. In this case, that would be 0.4. Since 0.4 has one significant figure, then the product should be reported with one significant number. That should be 0.1.

At a grocery store, eggs come in cartons that hold 12 eggs. Experience indicates that 78.5% of cartons have no broken eggs, 19.2
AfilCa [17]

Answer:

0.8930 or 89.30%

Step-by-step explanation:

The probability that an egg is the only broken one in the carton, given that it is broken, is determined as the percentage of cartons with exactly one broken egg, divided by the percentage of cartons with broken eggs.

19.2% of cartons have exactly one broken egg.

The percentage of cartons with broken eggs is:

B = 19.2\%+2.2\%+0.1\%\\B=21.5\%

Therefore, the probability that this egg is the only broken one in the carton is:

P = \frac{19.2\%}{21.5\%}=0.8930 =89.30\%

There is a 0.8930 or 89.30% that this is the only broken egg.

Find the measure of angle 2... State what the relationship is between angle 2 and the 18 degree angle
sergij07 [2.7K]

Answer:

-The Relationship:

Both \angle 2 and the 18\textdegree angle are supplementary.

The measure of \angle 2:

\angle 2 = 162\textdegree

Step-by-step explanation:

-The relationship about both \angle 2 and the 18\textdegree angle, is that they are supplementary, which they both add up to 180\textdegree.

-To find the measure of \angle 2, you need to subtract 18 from 180 to get the actual angle measurement of \angle 2:

Finding the measure of \angle 2:

180 - 18 = 162

\angle 2 = 162\textdegree

So, now you have the measure of \angle 2 .

How do you find a circumference of a circle?
Tanzania [10]

Answer:The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle). Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!Hope it helps!!!!
