Answer:

The sum of all the data values divided by the number of data values is 7.

Explaination:

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

Answer:

The last one

Step-by-step explanation:

We know that the mean is 7, what we are trying to identify is which situation correctly describes how to find the mean.

<u>Define</u>

Mean = Sum of values divided by number of data values

<u>Reasoning</u>

For "The middle value of the ordered data set is 7."

The middle value is known as the median not mean therefore this answer is not correct.

For "The value that occurs most often in the set is 7."

The number that occurs the most is known as the mode not the mean therefore this is not the correct answer

For " The difference between the smallest value and the largest value is 7.

"

The difference between the smallest and largest number is known as the range therefore this answer is not correct.

We're left with "The sum of all the data values divided by the number of data values is 7." which does indeed correctly describe how to find the mean.

The measure of ∠1 =<br><br> 188<br> 172<br> 94
yanalaym [24]

Answer:  Third option is correct.

Step-by-step explanation:

Since we have given that

There is a cyclic quadrilateral.

As we know that "Sum of opposite angles in a cyclic quadrilateral is supplementary.":

so, it becomes,

86^\circ+\angle 1=180^\circ\\\\\angle 1=180^\circ-86^\circ\\\\\angle 1=94^\circ

Hence, the measure of  ∠1 = 94°

Therefore, Third option is correct.

Find the measure of angle y. Round your answer to the nearest hundredth. Right triangle
e-lub [12.9K]
<h3>The measure of angle y is 35.68 degrees</h3>

<em><u>Solution:</u></em>

Given that,

hypotenuse 12

Opposite 7

Find the measure of angle y

y is unknown and is between the hypotenuse and adjacent side

The figure is attached below

In a right triangle, the sine of the angle is the ratio of the side opposite to the angle to the hypotenuse

Therefore,

sin\ y = \frac{opposite}{hypotenuse}\\\\sin\ y = \frac{7}{12}\\\\sin\ y = 0.5833\\\\y = sin^{-1}\ 0.5833\\\\Use\ arcsin\ calculator\\\\y = 35.6829 \\\\y \approx 35.68

Thus measure of angle y is 35.68 degrees
