In square qrst, points u and v are midpoints. if the square has a side length of 18 mm, what is the probability that a point chosen at random in the square lies in the shaded triangle region? round the answer to the nearest thousandth.
a. 0.028
b. 0.056
c. 0.125
d. 0.222

We can get the probability by 1st calculating the area of the shaded triangle region and the area of the square.

Area of triangle = b h / 2

Where,

b = h = half of side length of square = 9 mm

Area of triangle = 9 mm * 9 mm / 2

Area of triangle = 40.5 mm^2

Area of square = s^2

Area of square = (18 mm)^2

Area of square = 324 mm^2

Probability that a point is in the shaded region = Area of triangle / Area of square

= 40.5 / 324

= 0.124

ANSWER: The closest answer is letter C. 0.125

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
