Answer:84

Step-by-step explanation: add all the numbers together you should get a total of 395

Step 2 divide 395 by 5 = 79 that’s your average so far

Step 3 ( x the 6th test)

5• 79 + x =80 You will first multiply

6 5•79 = 395

Then 80 • 6 =480

Then subtract 480-395 = 85 is the lowest you will need to make

The area of a trapezoid is 36.36 square centimeters. One base of the trapezoid is 14.8 centimeters. Its height is 3.6 centimeter
zmey [24]
The third answer (Dividing the area by the height, multiplying the quotient, etc) is correct.

If we multiply by the height, we receive an expression equal to the sum of the bases divided by two.  Multiplying by two, we now have the sum of the bases.  Subtracting one base gives the length of the other base.

What is the standard deviation of the data set given below 5 7 9 11 13
AURORKA [14]

Answer:

3.1623 (sqrt(10))

Step-by-step explanation:

Standard Deviation is calculated by first squaring the differences between the observations and the mean and then taking the square root of the sum of the squares of the differences divided by the number of observations - 1.

Mean = Sum of Observations/Total Observations

Mean = (5 + 7 + 9 + 11 + 13)/5 = 45/5 = 9.

Square of the mean = 9^2 = 81.

Now subtracting the mean from each observation and squaring it gives:

(5 - 9)^2 = (-4)^2 = 16

(7 - 9)^2 = (-2)^2 = 4

(9 - 9)^2 = (0)^2 = 0

(11 - 9)^2 = (2)^2 = 4

(13 - 9)^2 = (4)^2 = 16

Sum of squares = 16 + 4 + 0 + 4 + 16 = 40.

Standard deviation = sqrt(40/4) = sqrt(10) = 3.16 (correct to 2 decimal places).

Therefore, answer is 3.16!!!
