Answer: 5%
Step-by-step explanation:
A meteorologist predicted that Monday's hight temperature would be 76F and on Monday, the temperature reached 80F.
The percentage error will be
Percentage error=
(Exact value-Forecasted value)/exact value x 100
= 76-80/80 × 100
= -4/80 × 100
=4/80 × 100
= 400/80
= 5%
The percentage error is 5%.
Answer:
No ABC is not a triangle
Step-by-step explanation:
Perimeter = 22 cm
AB = 8 cm ; BC = 8 cm
AC = 22 - ( 8 + 8 ) = 6 cm
But all those sides doesn't follow Pythagorean Theorem(AB^2 + BC^2 = AC^2) ....because 8^2 + 8^2 isn't equal to 6^2 ......
Had it followed the theorem , it could have been a right angle triangle...
