Eric invested 5000 dollars in the stock market. The value of his stock increased by 13%. a) what is the amount earned from this

blagie [28]

Answer:

$Earnings = 650$

$New\ Value = 5650$

Step-by-step explanation:

Given

$Amount = 5000$

$Rate = 13\%$

Solving (a): The earnings.

This is calculated as:

$Earnings = Amount * Rate$

$Earnings = 5000 * 13\%$

$Earnings = 650$

Solving (b): New Value

This is calculated as:

So, we have:

$New\ Value = Amount + Earnings$

$New\ Value = 5000 + 650$

$New\ Value = 5650$

a) Choose Z since the σ is smallest . The smaller the σ the higher the consistency. Also we can see that the fewest day the student attendance is higher than other while the highest day is the same with others. (L = 130 ,H = 180)

b) Choose W since mean in W is the highest.

A) 9(x + 4) = 27

9x + 36 = 27

9x = 27 - 36

9x = -9

x = -9 ÷ 9

x = -1

B) x/3 - 5 = 6

x/3 = 6 + 5

x/3 = 11

x = 11 × 3

x = 33

C) 15 + 3 ( x -7 ) = -30

15 + 3x - 21 = -30

3x + 15 - 21 = -30

3x - 6 = -30

3x = -30 + 6

3x = -24

x = -24 ÷ 3

x = -8
