Hello! Here is your answer!
Mean: the mean is the number's all added up and then divided by the number of number's in the equation,
Example:
24 58 93 44 56 Now first we add 24 = 58 = 82 82 + 93 = 257 257 + 44 =
301 301 + 56 = 357 Now we divide our number by the amount of number's
listed "24 58 93 44 56" 357 ÷ 5 = 71.4! And that is the mean,
Mode: Now the mode is the most used number we need to find that to get our answer,
Example: 28 34 58 28 34 53 24 28 Now as you can see there is two 34's one 58 one 53 one 24 and three 28's so the mode is 28!,
Median: The median is the middle number if there is none it would be the half of the two middle number's,
Example: 0 10 20 30 40 50 60 70 80 90 100 The median is 50 to get it simply divide 100 by 2 so the median is once again 50,
Further example: To get the median when there is no middle number 20 35 45 60 80 you would simply get the number between 35 and 45 so the median would be 40,
Range: To find the range you must subtract the highest number by the lowest number
Example: 41 56 58 55 23 63 now we find the highest and lowest number 23 and 63 so we subtract 63 by 23 63 - 23 = 40 so the range is 40. Hope this helps you! :)

Answer:
70°
Step-by-step explanation:
Connect the center of the circle with endpoints of the chord. Let the center of the circle be point O and endpoints of the chord be points A (let point A lie on the tangent line too)and B.
From the figure, central angle AOB has the measure of 220°.
Consider triangle AOB. This triangle is isosceles triangle because OA and OB are both radii. In this triangle the measure of angle AOB is 360° - 220° = 140°.
Angles OAB and OBA are angles adjacent to the base AB, so they are congruent. The sum of the measures of all interior angles in triangle is always 180°, so
m∠OAB + m∠OBA + m∠AOB = 180°
m∠OAB = m∠OBA = 1/2 (180° - 140°)
m∠OAB = 20°
Since drawn line is tangent line, then OA is perpendicular to this tangent line and
x° = 90° - 20°
x° = 70°
Substitute x for "a number". This is a verbal equation, so it will look like this:
3x+4x+1=6x. Then solve for x.
Answer:
151.5
Step-by-step explanation:
the ratios of the sides PQ:ST=4:3, and the perimeter of POQ is 202, so 3/4 of 202 is 151.5
