<span>Found the complete problem, see attachment. 

My answer: 
C and Y are not independent events because P(C∣Y) ≠ P(C).

Probability of C = 110/300 = 0.37
Probability of Y =   75/300 = 0.25

Probability of (C|Y) = 0.37 * 0.25 = 0.0925

As you can see, </span><span>P(C∣Y) is 0.0925 which is not equal to P(C) = 0.37. Thus, C and Y are not independent events. </span><span>

40% of 400- how to solve please (thanks
Alexxandr [17]

Step-by-step explanation:

What is 40% of 400?

  • Convert the problem to an equation using the percentage formula: P% * X = Y
  • P is 40%, X is 400, so the equation is 40% * 400 = Y
  • Convert 40% to a decimal by removing the percent sign and dividing by 100:40/100 = 0.4
  • Substitute 0.10 for 10% in the equation: 40% * 400 = Y becomes 0.4 * 400 = Y
  • Do the math: 0.4 * 400 = 160
  • Y = 160
  • So 10% of 150 is 160
  • Double check your answer with the original question: What is 40% of 400? Multiply 0.4 * 400 = 160

Isabella has already baked 4 pies, and she can bake 2 pies with each additional cup of sugar she buys. Write an equation that sh
Alla [95]

Answer:

It would be y = 2x+4

Step-by-step explanation:

This is because Isabella has started with 4 baked pies and is gaining additional pies with in amounts of 2 pies.

With this, 4 would be by itself and 2 would be attached to the variable x for the unknown amount of additional pies.

Lastly, you would have this all equaling y, as y is the total amount of pies.

I had $80.45 in my bank account on Monday. I deposited $20.50 on Tuesday, Wednesday, and Thursday. I then withdrew $37.25 on Fri
brilliants [131]

Answer:

$104.70

Step-by-step explanation:

The equation would be set up like this: 80.45 + 20.50(3) - 37.25. You started off with $80.45 in your bank account and deposited, or added, $20.50 every day on Tuesday, Wednesday and Thursday. That would mean you added $20.50 three times. Adding $80.45 + $20.50 + $20.50 + $20.50, simplified to $80.45 + $20.50(3)  would get you $141.95 in total. Then, on Friday, you withdraw $37.25, getting the equation $141.95 - $37.25, leaving $104.70 for the weekend.
