How do you round an irrational number to the nearest hundredth

1 answer:

7 0

To round to the nearest cent, nearest penny, or nearest hundredth, you will need to locate the hundredths place. Then look at the digit to the right. If it is 5 or above, the number in the hundredths place will be increased by 1 and all the rest of the numbers after it are dropped. If the number is 4 or below, you leave the digit in the hundredths place alone and drop all the rest of the numbers after.

<span>Just remember, if the problem asks you to round to the nearest hundredth, make the end result look like money, meaning only two digits after the decimal point!</span>

What is the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81?

Marizza181 [45]

Answer: d. 1.3333

Step-by-step explanation:

We know that the standard error of a sampling distribution is given by :-

$S.E.=\dfrac{\sigma}{\sqrt{n}}$

, where $\sigma$ = Population standard deviation.

n= Sample size.

AS per given , we have

$\sigma =12$

n=81

Then, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 will be :-

$S.E.=\dfrac{12}{\sqrt{81}}$

$=\dfrac{12}{\sqrt{9^2}}=\dfrac{12}{9}\\\\=\dfrac{4}{3}\\\\\approx1.3333$

Hence, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 is 1.3333.

Thus the correct answer is d. 1.3333 .

You have 5 pieces of wood. What is the total length of the wood? 73cm, 1.6m, 2.87m, 325cm and 4.04m

skad [1K]

First, you need to make sure that they're in the same measurement ration

1 m = 100 cm

so, now you have

73 cm + 160 cm + 287 cm + 325 cm + 404 cm

The total length would of all the wood would be be 1249 centimeters or 12.49 meter
