Without calculating, this would be about 9 because 54/6=9
Answer:
Any number less than 1
Step-by-step explanation:
Let x be the number Lin multiplies by 7/8. So, we have:
(7/8)*x < 7/8
We need to find the possible values for x. Lets start by dividing both sides of our inequality by (7/8) in order to get x alone on the left side.
(7/8)*x / (7/8) < (7/8)/(7/8)
Reordering:
(7/8) / (7/8) * x < (7/8)/(7/8)
As any number divided by itself (except from 0) is equal to 1:
x < 1
So, the number that Lin multiplied by 7/8 MUST be less than 1. This is evident, as any positive number multiplied by a number less than 1 will decrease, doesn't matter if its a negative or positive number.
So, such number is less than 1. Any number less than 1 could be Lin's number.
Answer:
Mode is 20.
Step-by-step explanation:
Mode is the value or values in the data set that occurs most frequently.
{12, 12.50, 13, 18.50, 20, 20}
20 is the number that occurs most frequently.
hope this helps and is right :)
a - b is 9
Step-by-step explanation:
- Step 1: Given a² + b² = 1305, a × b = 648. Find a - b using the identity for (a - b)²
⇒ (a - b)² = a² + b² - 2ab
⇒ (a - b)² = 1305 - 2 × 648 = 1305 - 1296 = 9
⇒ (a - b) = 9
