Answer:
x = 133
Step-by-step explanation:
First, determine what total sum would be needed for the mean to be 114. Do this by multiplying 114 by 6 (bc total number of values in data set includes the variable <em>x</em>).
114 x 6 = 684
Next, add the five known values to get a sum of 551.
Now, just: 684 - 551 = 133
For the mean to be 114, x must equal 133.
36/7^2c that’s what I got I’m sure that is right
Answer:
42.5 units²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = h (a + b)
where a and b are the parallel bases and h the perpendicular height
Here a = 5, b = 12 and h = 5, thus
A = 0.5 × 5 × (5 + 12) = 0.5 × 5 × 17 = 42.5 units²
