Answer: If I put a line over the number that means continued Ex: (23.333333..., 3.098888 or 56.77777...)

11. Mean 1 + 2 + 3+ 3+ 4+ 4+ 4+ 5+ 5 / 9 = 31/9 =26.5 .Median 4 Mode 4 Range 5 - 1 = 4. _

12. Mean 6.5 + 7.5 + 7.5 + 7.5+ 8 + 8.5 + 8.5 + 8.5 + 8.5 + 8.5 +9 = 88.5/11 =8.045

median 8.5 mode 8.5 range 9 - 6.5= 2.5

13. Mean 5.75 + 7.25 + 7.75 + 8 = 28.75/4 = 7.1875. median 7.25 + 7.75 = 15/2 = 7.5 range 8 - 5.75 = 2.25

14. Mean 5 + 5 + 6 + 6 + 6 + 7 + 7 + 7 + 7+ 7 = 63/10 = 6.3 median 6 + 7 = 13/2 = 6.5 . mode = 7 range 7 - 5 = 2. _

15. Mean 5 + 5 + 5 + 7+ 7+ 7+ 7 + 7+ 7+ 7/9 = 62/9 = 57.5 median 2 mode 2 range 7 - 5 = 2.

16. 1 + 2 + 2 + 2 + 2 + 2 + 3 + 5 + 5 + 5= 29/10 = 2.9 Median 2 mode 2 range 5 - 1 = 4.

17. 1 +2 + 3 + 5 + 6 + 6+ 6 + 8 + 13 + 19 = 69/10 = 6.9 median 6 mode 6 range 19 - 1 = 18. __

18. 1 + 2 + 2 + 2 + 2+ 2 + 2 + 2 + 4 + 4 + 5 = 27/11 = 2.45 median 2 mode 2 range 4.

Step-by-step explanation:

Mean

Add up all the numbers, then divide by how many numbers there are. Ex: 2, 3, 4. 2 + 3 + 4 = 9. Since there is 3 numbers we divide. 9 divided by 3 equals 3 so 3 is your mean.

Median

Arrange your numbers from least to greatest.

Count how your numbers.

If you have a set of odd numbers, the number in the middle is your median. Ex: 2, 3, 6, 7, 1, . your median is 6.

Mean

If you have a set of even numbers use the 2 numbers in the middle then divide. Ex: 1, 5, 3, 8, 9, 2. The two numbers in the middle are 3 and 8 . 3 plus 8 equals 11. 11 divided by 2 is 5.5. the mean.

Mode

write the numbers from least to greatest. The number that shows the most is your mode. Ex. 4 , 6 ,7 ,3 ,1 3, 3, 3, 2 3, . The number that appears the most is 3. So 3 is the mode. If there is no number that appears more than all the others put NONE or N/A in the blank.

Range

To find the range put the subtract the greatest number and least number. Ex: 2, 4, 7, 1, 8. 1 , 2, 4, 7, 8. 8 mins 1 is 7 so 7 is the range.

Solve the proportion. i need help.<br> x+3/6=8/3<br><br> x=?
stellarik [79]

Answer:

x = 2 1/6 (13/6)

Step-by-step explanation:

to solve the proportion you must first find the LCF or least common factor

that is 6

so turn 8/3 into 16/6 by multiplying it by 2/2

x + 3/6 = 16/6

then you subtract 3/6 from both sides

x = 13/6

x is 2 1/6

Find an equation of the tangent line to the graph of
lakkis [162]

Answer:

y + 4 = -3 (x - 5)

In other words,

y = -3 x + 11

Step-by-step explanation:

The slope of the tangent line to y = g(x) at x = 5 is the same as the value of g'(x). g'(5) = 3. Therefore, 3 will be the slope of the tangent line.

The tangent line goes through the point of tangency (5, g(5)). g(5) = -4. Therefore, the tangent line passes through the point (5, -4).

Apply the slope-point form of the line. The equation for a line with slope <em>m</em> that goes through point (a, b) will be y - b = m(x - a). For the tangent line in this question,

  • m = 3,
  • a = 5, and
  • b = -4.

What will be the equation of this line?
