The required probability of giving class period run between 51.5 and 51.75 is 0.125.
The lengths of her classes are uniformly distributed between 50 and 52 minutes.
<h3>What is the probability?</h3>
Probability, can be define as the ratio of favorable events to the n number of total events.
since,

p(r) = 0.125
Thus, the required probability of class period runs between 51.5 and 51.75 is given by 0.125

Answer:
A = 57.97 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A =
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 6.2, a = 10.8 and b = 7.9, thus
A =
× 6.2 × (10.8 + 7.9) = 3.1 × 18.7 = 57.97 cm²
Answer:
27
Step-by-step explanation:
30/100 ×90 is 27.
it's making me type more but that's the answer :)
X = 180 - 58 - y
Y = 180- 126= 54
X= 180 - 58 - 54
X= 180- 112= 68 degrees
