A cinema seats 280 people. if 98 people are in the cinema, what percentage of the seats are filled ?
Answers
The total number of seats are 280
Out of this 98 seats are filled
Hence it is expressed in fraction as
(part out of whole)
To convert any fraction into percentage, we just need to multiply it with 100
×100
= 35 %
Hence 35% of the cinema is filled

A manufacturer claims that only 1% of their computers are defective, but in a sample of 600 3% were found to be defective. If the 1% claim were true there would be less than 1 chance in 1000 of getting this number of defects in the sample. Is there statistically significant evidence against the manufacturer's claim? Why or why not?No, because the difference between a 1% and a 3% defect rate is insignificant. Yes, because the source of the data was unbiased. Yes, because the results are unlikely to occur by chance. No, because the sample size was too small to reach a conclusion.

The coordinates of the vertices of the image after the 90-degree counter- clockwise rotation about the origin is :
- ( - 3, 2 )
- ( 1, -3 )
- ( 1, 2 )
How to rotate 90-degree counter- clockwise rotation about the origin?
To perform a 90-degree counterclockwise rotation about the origin, follow these steps:
- Write down the coordinates of the point you want to rotate. Let's call the point ( x , y).
- To perform a counterclockwise rotation, switch the x and y-coordinates and negate the new x-coordinate. The new coordinates will be ( - y , x).
This means that the vertices will become :
( 2 , 3) ⇒ ( - 3, 2 )
( - 3, -1) ⇒ ( 1, -3 )
( 2, - 1) ⇒ ( 1, 2 )

Answer:
s = -43.245
Step-by-step explanation:
First, you move the constant to the right:
-s=44-0.755
Calculate:
-s=43.245
Then, you change the signs:
s=-43.245

tiles. How many tiles will she need?
56 tiles
15 tiles
30 tiles
Answers
Final answer:
To tile a 7-foot by 8-foot room with one-foot square tiles, the builder will need 56 tiles.
Explanation:
To find the number of tiles needed to tile a room, we can divide the area of the room by the area of each tile. The area of the room is 7 feet by 8 feet, which is 56 square feet. The area of each tile is 1 square foot. So, to find the number of tiles needed, we divide 56 by 1, which gives us 56 tiles.
