Let ABCD be this parallelogram
AB + BC + CD + DA = 50, but AD = BC and AB = DC, Then:
2.AD + 2.AB = 50 and :
AD+AB = 25 . We also know that AB+1 = AD (Given), then:
AD + (AD+1) = 25
2.AD = 24
AD = 12, THEN AB = 12+1=13
Calculate DB the diagonal perpendicular to AD, using Pythagoras:
AD² + DB² = AB²
12² +DB² = 13²
DB² = 13² - 12² = 25
AND DB= 5
The relative frequency probability that an accurate forecast will be made the next day is ratio of the number of correct predictions made to the total number of predictions is 0.575
The total number of predictions made = 40
The number of correct predictions = 23
The relative frequency probability is given by ;
- Number of correct predictions ÷ total number of predictions made
Therefore, the relative frequency probability that an accurate forecast will be made tomorrow is 0.575
