Use a formula to calculate the amount of money you would have if you invest $3000 at a rate of 5% compounded quarterly, for 3 ye
snow_lady [41]

Answer:

At 5% compounded quarterly, the amount of $3,000 would be $3,482.

At 1.5% compounded monthly, the amount of $3,000 would be $3,138.

Step-by-step explanation:

Option 1:

Rate = r = 5%

Times = b = 4

y = a (1 + r)ⁿ

For compounded quarterly the rate of interest and Number of years will be written as follows:

y = a [1 + (r / b)]ⁿᵇ

y = $3,000 [1 + (0.05 / 4]³ ˣ ⁴

y = $3,000 [1 + 0.0125]¹²

y = $3,000 [1.0125]¹²

y = $3,000 x 1.160755

y = $3,482

Option 2:

Rate = r = 1.5%

Times = b = 12

y = a (1 + r)ⁿ

For compounded monthly the rate of interest and Number of years will be written as follows:

y = a [1 + (r / b)]ⁿᵇ

y = $3,000 [1 + (0.015 / 12]³ ˣ ¹²

y = $3,000 [1 + 0.00125]³⁶

y = $3,000 [1.00125]³⁶

y = $3,000 x 1.045998

y = $3,138

Hence As compared to Option 1, Option 2 has low rate of return by $344. Therefore Option 1 should be selected.

Solve for x:<br> 3(x+1)=5 (x-2)+7
Aleonysh [2.5K]

Step-by-step explanation:

3( x +1) = 5 (x - 2) + 7

3x + 3 = 5x - 10 + 7

5x - 3x = 3 + 10 - 7

2x = 13 - 7

2x = 6

Therefore x = 3

Find the sample space for a committee of two chosen from Alice (A), Bill (B), Carol (C), and David (D).
Finger [1]

Answer:

(a) C.  {(A, B), (A, C), (A, D), (B, C), (B, D), (C, D)}

(b) C. {(A,B),(A,D),(B,C),(C,D)}

Step-by-step explanation:

Given four members eligible for selection:

Alice (A), Bill (B), Carol (C), and David (D).

The possible combinations are:

(A,B),(A,C),(A,D),(B,A),(B,C),(B,D),(C,A),(C,B),(C,D), (D,A),(D,B), (D,C)

<u>Part A</u>

Since the same pairs are equal i.e. (A, B)=(B , A),

The Sample space for a committee of two is:

{(A,B),(A,C),(A,D),(B,C),(B,D),(C,D)}

This is Option C.

<u>Part B</u>

If both genders must be represented, we remove the entries that contain the same gender from the sample space above.

A and C -Female

B and D - Male

{(A,B),(A,C),(A,D),(B,C),(B,D),(C,D)}

Therefore, the sample space if both genders are to be represented is:

{(A,B),(A,D),(B,C),(C,D)}

This is Option C.
