Answer:
area = 50 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 4, a = 15 and b = 10, thus
A =
× 4 × (15 + 10) = 2 × 25 = 50 cm²
Answer:
171
Step-by-step explanation:
multiply 380 times 0.45 so like this:
380 x 0.45 = 171
Answer:
Mean = 33+ 22+35+27+23+35+27+36 = 238/8 = 29.75
Median = 27+23 = 50/2 = 25
Mode = 35
Range = 36 - 22 = 14
