Answer: lower bound = 9550
<u>Step-by-step explanation:</u>
Since the number is rounded to the nearest hundred, the actual value is somewhere between 9550 (which rounds up to 9600) and 9649 (which rounds down to 9600).
The lower bound is: 9550
The upper bound is: 9649
Answer: O 3-7,5, 18, 24, 32}
O {-9, 7, 15, 22, 26}
these two sets are not equal
Answer:
X= blue tiles
Y = red tiles
X/y = 4/21
X+y= 425
Y= 357 tiles
X= 68 tiles
Step-by-step explanation:
red and blue ceramic tiles are laid according to a pattern.
The pattern= every 21 red tiles used, 4 blue tiles are used
Total number of tiles used = 425 tiles
X= blue tiles
Y = red tiles
X/y = 4/21
X+y= 425
21x= 4y
X= 4y/21
X+y= 425
4y/21 + y = 425
25y= 425(21)
Y=( 425*21)/25
Y= 357 tiles
X= 4y/21
X= (4*357)/21
X= 1428/21
X= 68 tiles
Answer:
1/9
Step-by-step explanation:
The die has sides 1,2,3,4,5,6
P( less than 5) = 1,2,3,4 / total
=4/6 = 2/3
Then rolling again
P(greater than 5) = 6/total = 1/6
P( less than 5,greater than 5) = 2/3* 1/6= 1/9
The probability would be 2/6 or 1/3
