Answer:
Step-by-step explanation:
the shape can be divided into two semi-circles of radius 5 cm and (11x10) cm rectangle
so,
area = (2 x 0.5x pi x 5x 5) + (11x10) = 188.5 cm sq
The error Giovanna made in her calculation is multiplying 7 by 2 and adding with 5/8(step 3)
<h3>Fraction</h3>
Her calculation:
- 7 (2 and StartFraction 5 over 8 EndFraction): 7(2 5/8)
- 7 (2 + StartFraction 5 over 8 EndFraction): 7(2 + 5/8)
- 14 + StartFraction 5 over 8 EndFraction: 14 + 5/8
- 14 and StartFraction 5 over 8 EndFraction: 14 5/8
Her error was multiplying 7 by 2 and adding with 5/8(step 3)
Correct calculation:
7(2 + 5/8)
= 14 + 35/8
= (112+35) /8
= 147/8
= 18 3/8

Answer:
No, his inference is not valid
Step-by-step explanation:
the data shown represents the statistic of 100 people's preferred ways to view movies in total
out of that 30/100 people prefer to watch in theatre.
trent inferences that out of 400 people 300 would prefer to watch in theatre another way to write this is 300/400
if we multiply the data we're given so that the denominators match Trent's inference. The data tells us that 120/400 would prefer to watch in theatre, so his inference is not valid.
