Answer: $0.05
Step-by-step explanation:
Mean of a given set of numbers simply means that one should find the average of the numbers. Therefore, the mean change of the stock prices will be:
= ($1.25 + -$0.75 + $1.25 + -$0.75 + -$0.75) / 5
= $0.25 / 5
= $0.05
Therefore, the mean change of the stock prices is $0.05.
Answer:
The total cost of the bike is $180.
Step-by-step explanation:
Given that Juanita has saved 35% of the money for a bike.
Let the total cost of the bike = x
As she has saved $63 dollars which represents the 35% of the money for a bike.
In other words, 35% of the total cost is $63 dollars.
As the total cost = x
Thus,
35% of x = 63

Multiply both sides by 20

simplify

Divide both sides by 7

Simplify
$
Thus, the total cost of the bike is $180.
Step-by-step explanation:
3 - 2(b - 2) = 2 - 7b
To solve this first distribute -2 to (b - 2)
3 + (-2b + (-2) x -2) = 2 - 7b
when we simplify this it becomes:
3 + (-2b + 4) = 2 - 7b
We take (-2b + 4) out of the parenthesis:
3 - 2b + 4 = 2 - 7b
Now simplify again.
7 - 2b = 2 - 7b
Now send all the b's to one side and constants on the other.
7 - 2 = -7b +2b
5 = 5b
b = 1
