Answer:
a = 20
Step-by-step explanation:
The mean is calculated as
mean = 
=
= 
Then
= 27 ( multiply both sides by 5 to clear the fraction )
115 + a = 135 ( subtract 115 from both sides )
a = 20
Answer:
y=-2/3x+10
Step-by-step explanation:
y=2/3x-11
plug in plot and remove intercept
6=-2/3(6)+b
6=-4+b
10=b
y=-2/3x+10
Answer: 360ft
Explanation:
x = 18/1/20
x = 18 x 20
x = 360ft
The correct representations of this solution are
- (d) A number line going from negative 5 to positive 5. An open circle appears at positive 3. The number line is shaded from positive 3 to negative 5.
- (e) (3, ∞)
<h3>How to determine the solution set?</h3>
The inequality is given as:
6 + 2n > 12
The solution is given as:
n > 3
When the above inequality is represented as an interval, we have:
(3, ∞)
Also, the inequality symbol > is represented using an open circle.
This means that the number line would use an open circle and the arrow would point right
Hence, the correct representations of this solution are (d) and (e)

Answer: There is 680% increase for the fund.
Step-by-step explanation:
Since we have given that
Number of shares they purchased = 1000
Cost of per share at the time of their marriage = $10
So, Amount of fund will be

Cost per share after 30 years = $78
So, Amount of fund will be

Percentage of increase for the fund will be given as

Hence, there is 680% increase for the fund.
