You have three figures here: a parallelogram, a rectangle, and a trapezoid.
area of a parallelogram =bh
area of a parallelogram =18 x 16
area of a parallelogram =288 ft²
area of a rectangle= wl
area of a rectangle= 17 x 56
area of a rectangle= 952 ft²
area of a trapezoid= base1 +base2/2 *h
area of a trapezoid=21+38/2 *16
area of a trapezoid= 59/2 *16
area of a trapezoid= 29.5 *16
area of a trapezoid=472ft²
The last step is to add all three areas together.
288 ft² + 952 ft² + 472 ft² = 1712ft²
Write and solve an equation of ratios:
15 min 3 racks
---------- = -------------
x 36 racks
Solving this for x: 3x = (15)(36) => x = 180 minutes.
convert this into hours: 180 min 1 hr
------------ * -------------- = 3 hrs (answer)
1 60 min
Answer:
The 95% confidence interval is from 64 to 88
Step-by-step explanation:
The confidence interval has two values.
The lower limit, that is the mean subtracted by the margin of error.
The upper limit, that is the mean added to the margin of error.
So the 95% confidence interval is
76-12 to 76+12 = 64 to 88
