Answer:
The answer is -3,29
Step-by-step explanation:
Answer:
y = 3 + 12x - - - (1)
y = 9 + 10x - - - (2)
3 albums
$39
Step-by-step explanation:
Let number of download = x
Given :
I-moon :
Initial joining fee = $3
Cost per download = $12
Hence,
y = 3 + 12x - - - (1)
I - Toons :
Initial joining fee = $9
Cost per download = $10
y = 9 + 10x - - - (2)
For cost to be the same ;
Equate (1) and (2)
3 + 12x = 9 + 10x
Collect like terms
3 - 9 = 10x - 12x
-6 = - 2x
x = 3
It will take 3 albums
Cost :
3 + 12(3)
3 + 36 = 39

❖ The gray whale will need to come up 12 times during the 6 hr period.
Convert 6 hrs to mins:
1 hr = 60 mins
60 x 6 = 360 mins
Divide by 30 to see how many times the whale will need to come up:
360/30 = 12

Step-by-step explanation:
<u>Step 1: Define
</u>
y = home runs
x = hits
[Best Line of Fit] y = 0.15x - 1.5
<em>We can use this to predict the average of the scatter plot.
</em>
hits = x = 200 times
<u>Step 2: Solve for </u><em><u>y</u></em><u> home runs</u>
- Substitute [BLF]: y = 0.15(200) - 1.5
- Multiply: y = 30 - 1.5
- Subtract: y = 28.5
Remember that this is only a <em>prediction.</em> Actual data can vary. The best line of fit tells us that if a player hits 200 times, we would get approximately 28.5 home runs.
