A. The value of r = -0.83 means that there is a good negative correlation between the analyzed variables. In option A, the relation is positive, then it is not the correct answer. In option C, the values are highly dispersed, then the absolute value of r = 0.83 seems too high for this case. Therefore, Option B seems to be the correct option.

B. The equation y = 0.6x + 1.75 has a positive slope. The only graph with a line of best fit whit a positive slope is option A.

Answer:

Broker1 with $66.

Broker2 with $54.25

Broker4 with $50

Broker3 with $47.5

Broker5 with $33.5

Explanation :

Total number of shares Cindy have : 300

Market Price per share : $25

Total price for the shares : 300 $\times$ $25

= $7500

Now ,

Case 1:

Commission provided by broker1 = 0.75%

Online fees provided by broker1 = $ 10

Total price provided by broker1= $\frac{75}{10000}\times7500 +$10$

=$66.25

Case 2:

Commission provided by broker2= 0.5%

Online fees provided by broker2=$17

Total price provided by broker2= $\frac{5}{1000}\times 7500 + $17$

=$54.5

Case 3:

Commission provided by broker 3= 0.6% for 100 0r few

Not applicable because the total shares are 300

For over 100 shares

Commission provided= 0.5%

Online fees = $10

Total price = $\frac{5}{1000}\times 7500 + $10$

=$47.5

Case 4:

For more than 100 shares

Online fees for buying and sharing= $50

Total price = $50

Case5 :

Commision for a share bought or sold = 0.05%

Online fees =$30

Total Price= $\frac{5}{10000}\times 7500 + $30$

=$33.75

Write three equations whose solution is x=3.5

My name is Ann [436]

Answer:

1. 2x + 23 = 30

2. 3x + 19.5 = 30

3. (10x - 20)/ 5 = 3

Explanation:

Work backward:

1. 2x + 23 = 30

Start:

x = 3.5

Multiply the equation by 2:

2x = 2 (3.5)
2x = 7

Subtract 30 from both sides

2x - 30 = 7 - 30
2x - 30 = -23

Add 23 and 30 to both sides:

2x + 23 = 30

2. 3x + 19.5 = 30

Start:

x = 3.5

Add 6.5 to both sides:

x + 6.5 = 10

Multiply by 3:

3(x + 6.5) = 30

Distributive property:

3x + 19.5 = 30

3. (10x - 20)/ 5 = 3

Start:

x=3.5

Multiply by 10:

10x = 35

Subtract 20:

10x - 20 = 15

Divide by 5:

(10x - 20)/ 5 = 15/5

(10x - 20) / 5 = 3
