I would say it’s the first one because if you round it it is going to be approximately 12 so that is my reason and also why it isn’t number two is because if you subtract 13.26 and 7.98 you get 5. Something so that’s why

2. Two angle measures are in the ratio 5:9. Write
iris [78.8K]

The two angles are x and 9x/5

<h3 /><h3 />

Let the two angles we require be x and y.

<h3 /><h3>Ratio of both angles</h3>

We have that the ratio of both angles are x:y

Since both angles are in the ratio 5:9, we have that,

x:y = 5:9

⇒ x/y = 5/9

<h3 /><h3>Value of the other angle</h3>

So, we Make y subject of the formula

Multiplying both sides by y, we have

y × x/y = 5/9 × y

x = 5y/9

Multiplying both sides by 9, we have

9 × x = 5y/9 × 9

9x = 5y

Dividing both sides by 5, we have

9x/5 = 5y/5

y = 9x/5

So, the two angles are x and 9x/5

  • Mean is the best measure to represent the center of the data but when data have outliers it gets affected badly.
  • In that case, we use the Median as the best measure of center.

The given data is 12 10,9,68,12 .

As it can be seen that, the data have extreme value 68 ( called outliers).

In this case, we will use the Median as the best measure of center.

So, the most appropriate measure of center is the median.

HELP ASAP! PLS!! The Water Department checks the city water supply on a regular basis for
aleksandr82 [10.1K]

Answer:

B. 95% confident the average concentration of PCBs in the water supply is between 2.9 ppb and 3.5 ppb

Step-by-step explanation:

You are given the total number of samples, the concentration of lead, and the standard deviation. The standard deviation represents how inaccurate the estimation of the concentration of lead in the drinking water. This means that there can only possibly be a 0.3 ppb error in the estimation. 3.2-0.3=2.9, and 3.2+0.3=3.5
