Step-by-step explanation:
Answer:
D. 740
Step-by-step explanation:
Put the given value of b into the formula and do the arithmetic:
A(150) = 5×150 -10 = 750 -10
A(150) = 740
The band raised $740 from their sales.
The answer is choice A) 2
The main cluster of data is the group {12, 12, 14, 17, 18, 19} as they aren't very far apart in distance (plot the values on a number line). The range of this group is 7 since 19-12 = 7. Compare this to the distance from 2 to 12 which is 10 units; a far greater distance than 7. So the value 2 is on its own on an "island" so to speak
The number of years past when Alan was twice Vanessa's age is 14 years.
Current ages :
- Alan = 30 years
- Vanessa = 22 years
<u>We can set up an equation where, x = number of years when Alan was 2 times Vanessa's age thus</u> :
30 - x = 2(22 - x)
30 - x = 44 - 2x
Collect like terms
-x + 2x = 44 - 30
x = 14
Therefore, 14 years ago, Alan's age was twice Vanessa's age.
