Round 65,470 to the nearest thousand

1 answer:

5 0

You have to have a number that ends with three zeros. You have to look at the number formed by the last three digits. If this number smaller or equal to 500, you round down, meaning you just replace the three digits by three zeros, if it is bigger than 500, you round up, meaning you replace the three digits by three zeros and add one to the digit of the thousands.

Here, the last three digits form the number 470 which is smaller than 500 so the nearest thousand of 65470 is 65000.

Answer:

C. 34.15 oz

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu= 33, \sigma = 0.7$

How heavy does a box have to be for it to be labeled overweight?

Top 5%, so X when Z has a pvalue of 1-0.05 = 0.95.

So X when Z = 1.645.

$Z = \frac{X - \mu}{\sigma}$

$1.645 = \frac{X - 33}{0.7}$

$X - 33 = 0.7*1.645$

$X = 34.15$

So the correct answer is:

C. 34.15 oz

You scored 18 points in your fourth game because if you played 4 games and got 12 points each game that equals 48 points all together and if the average is 10 points for the first 3 games that equals 30 points for the three games so 48-30=18
